NGSS are about the art of teaching rather than just content expectations.  In this lesson, we will teach an ecology lesson about biodiversity this particular way.

Biodiversity is discussed in many objectives ranging from genetic variation, ecosystem dynamics, functioning and resilience, to interdependent relationships in habitats.  We will capture insects, an activity related to the BEST plots biodiversity protocol, as a vehicle to discuss differences in biodiversity among natural and disturbed habitats.  A follow up discussion in Landscape Restoration can be included.

At the conclusion of the lesson, students will be able to:

  • Define ecosystem and biodiversity
  • Design and carry out standardized protocols for conducting biological surveys
  • Use a simple dichotomous key to identify organisms
  • Graph data and interpret results

Concurrent Sessions

Sex Changes, Drugs, and Rockin’ Dead Zones: Effects of Human Contaminants on Aquatic Organisms
with Sara Garnett, Jake Nalley, and Emily Dittmar, MS/HS
Aquatic organisms can be very sensitive to changes in their environment. Increased human activity has led to large loads of contaminants being introduced to aquatic ecosystems, many of which have not been previously encountered at those levels. In addition to challenges at the individual level, these contaminants have the potential to alter ecological interactions at the community level. In this session, we will explore how over-fertilization of crops in Michigan can lead to changes in food webs and growing dead zones in Lake Erie and the Gulf of Mexico through a lab and an interactive game. We will also explore how a variety of novel contaminants can impact amphibian population dynamics.

Where the Wild Things Are: How Rainfall Drives Food Web Interactions
with Sarah Jones, Cara Krieg, and Dani Fegan, EL/MS/HS
Why would a wildebeest risk crossing a crocodile-infested river? Why does the African savannah have a wet and dry season? In this workshop session we will use the African Serengeti as a case study to examine how weather patterns explain these two seemingly unconnected phenomena. First, we will examine why the water cycle changes between the wet and dry season in Africa. Second, participants will take on the role of African animals and build a living food web. When the dry season comes each player will have to make a choice- will they follow the rain or can they survive until the rains return? For the elementary session we will emphasize the water cycle and food chain relationships and vocabulary. For the high school sessions we will go a step beyond and investigate what happens to the food web interactions when we add human disturbances such as wildlife reserve boundaries or domestic cattle herds.

Wonders of Wetlands (WOW!): improving water quality
with Dustin Kincaid, Susan Magnoli, and Amanda Charbonneau, advanced MS/HS 
Wetlands serve as sources, sinks, and transformers of materials transported across our landscape; thus, wetlands alter the chemistry of surface and ground waters in southwestern Michigan. In this workshop session participants will explore the role that sediments and microorganisms play in retaining sediments and nutrients. The specific objectives will be to explore (1) how wetlands trap organic materials and sediments, and (2) how microbes decompose these materials and cycle nutrients in the absence of oxygen. Participants will accomplish these objectives by observing sediments from several wetlands in the region. Teachers will also learn how to set up a long-term lab experiment that demonstrates how physical and biological features of wetland sediments transform materials and cycle nutrients over time.

Wonders of Wetlands (WOW!) for elementary levels
with Dustin Kincaid, Susan Magnoli, and Amanda Charbonneau, EL 
Wetlands are a ubiquitous part of the southwestern Michigan landscape and provide numerous important ecological services. Wetlands allow water to slowly filter into the ground, which cleans water, provides a buffer against flooding, and re- charges groundwater supplies. They also provide habitat for many animal and plant species. Wetlands provide an opportunity for students to explore parts of the water cycle, food webs, and many other ecological processes. In this session, we will introduce students to different types of wetlands and how they work with a series of presentations, games, and hands-on activities.

Telling the Story of a River
with Sara Syswerda, KBS, and Lisa Wininger, Plainwell Middle School, MS/HS
This session will describe a model for teaching about watershed dynamics, with this particular session focusing on the Kalamazoo River. We will look at maps of the Kalamazoo River and think about the dynamics of this particular watershed. We will talk about issues like evaluating water quality, river morphology, land use change, pollution from industrial sites, and dam removal. We will also work with ArcGIS Online to construct and interpret data in a geographic context.

Tools and Activities for Teaching About Global Carbon Cycling
with Hannah Miller and Andy Anderson, MS/HS
This session focuses on how to use animations, videos, and activities to help middle school and high students calculate how global carbon fluxes are connected with our daily activities and affect the global carbon balance.

Bioprospecting for Better Biofuels (In Your Backyard!)
with John Greenler and Leith Nye, GLBRC, MS/HS
Researchers at the Great Lakes Bioenergy Research Center (GLBRC) are investigating microorganisms living diverse environments that can efficiently breakdown cellulose, the primary component of plant cell walls. The enzymes produced by these microbes could be used to more efficiently convert fibrous, plant materials, such as switchgrass, into sugars and then biofuels. GLBRC researchers have made exciting discoveries studying microbial communities living in both unusual environments, such as tropical leaf-cutter ant colonies, and in more familiar places, such as cow poop. Join us to learn more about this fascinating area of biofuels research. We present a simple, classroom-tested lab activity for students to bioprospect for cellulose-degrading microbes in their local environments and share their findings directly with GLBRC scientists.

Roid Rage: Is It for Boys? How “true” are gender stereotypes?

Sep 122013
 

Jones_photo

Using a critical reading exercise and discussion, students will explore the perceptions and realities of sex differences in behavior, the causes of these differences. They will then use spotted hyenas, an unusual African mammal with a primate-like social system, to explore how scientists learn about individual and sex differences in aggressive behavior. The lesson will end with an activity that allows students to act as behavioral researchers. The lesson can be divided into three portions which can easily be made to stand alone, so teachers can do any and all portions as time permits.

At the conclusion of the lesson, students will be able to:

  • Read science presented in the media with a critical eye
  • Consider the causes of variation in animal and human aggression
  • Become more familiar how scientists study behavior
  • Learn about current research in spotted hyena behavior

Survivor: Extreme Environments: How invasive plants outwit, outplay and outlast their competitors

Sep 122013
 

Survivor_photo

This lesson plan provides a simple introduction to the mechanism of natural selection for students who are already familiar with concepts such as ecosystems, species, and variation. The lesson includes a short walk (can be done with nature photos) to identify the types and scales of variation in the natural world. Students then work in groups to adapt organisms (seeds) to different environments (soil types) in a fun, interactive exercise. Once seeds are well adapted to their environments, students will try to determine what made some of the organisms better than others, and try to predict how a new seed type will fare. The entire lesson is framed around how adaptions may help invasive species, but is equally applicable to native species. Teacher scripts are provided for the lesson introduction and accompanying power point.

This lesson would be appropriate in sections covering: natural selection, evolution, variation, invasive species, and adaptation.

At the conclusion of these lessons, students will be able to:

  • Explain the role of the environment in natural selection and evolution
  • Explain how variants lead to evolution through natural selection
  • Explain how invasive species create competition with native species
  • Explain how invasive species can affect natural selection and evolution

Students will gain an appreciation for why invasive species are important through a series of discussions, videos, and keying activities. A graphing activity will allow students to make graphs, interpret data from graphs, and draw conclusions based on data.

At the conclusion of the lesson, students will be able to:

  • Make and use simple dichotomous keys to identify species
  • Discuss why species identification skills are important to understanding and preventing invasion.
  • Convert a data table into a figure and draw conclusions

GK-12 in the community

Sep 092013
 

A new school year begins and our Fellows are back in the classrooms!  As always, we enjoy bragging on our Fellows, Partner-teachers, and districts, so here are a couple of recent GK-12 community happenings that we’re proud to be a part of.

Olivet’s Salmon in the Classroom (SIC) project

2013-05-13 Salmon Release (4)

Students in Russ Stolberg’s 8th grade classroom (with Fellow Jake Nalley) raised salmon fry from the DNR Wolf Lake hatchery during the 2012-2013 school year. In May, the class traveled to the MSU main campus to release the 4-inch fry into the Red Cedar River. The Olivet salmon project received first page honors on the Olivet Community Schools Newsletter, The Oakum, which you can read here.

2013-05-13 Salmon Release (1)

GK-12 Fellow Developed Lesson Plans go to Vegas!

Our Lessons Page and Interactive Lessons Table now contains full access to 90 Fellow and Partner-Teacher developed lessons for use in the classroom! Lesson content spans ecology and evolutionary biology, covering topics from nutrient cycling to predator-prey interactions, and folks from outside the K-12 Partnership are beginning to access our resources.

Recently, the Forest Service in the Spring Mountains National Recreation Area (northwest of Las Vegas) has adapted the Invasive Species Game to their environment as a stewardship lesson for students and teachers traveling to their new visitor’s center.

How Do Scientists Study Succession?

Aug 302013
 

KBS LTER from Bing

KBS scientists maintain 4 different types of successional plots: two get tilled every year and two have been undisturbed since 1988.  One of the tilled and one of the untilled plot get fertilized with nitrogen, an important nutrient limiting plant growth, every year; the other two plots do not.  Each year, scientists collect data on which plant species are there, how much they grow, and other characteristics of the plants.  In this lesson, students will explore this data to learn about succession, human disturbance (tillage), plant traits, plant life history, and population growth.  They will also gain scientific skills in graphing and math.

At the conclusion of the lesson, students will be able to:

  • Work with a real data set from the KBS LTER
  • Understand how management regimes can influence communities
  • Have a good understanding of using Microsoft Excel to analyze data

Students will learn the products and reactants of photosynthesis and respiration.  They will generate a circular diagram showing the cycle of carbon through carbon dioxide and sugars (the hypothesis).  They will generate predictions from this hypothesis that refer to specific treatments in the experiment they will set up.  They will set up an experiment with germinating bean seeds in petri plates (with or without water, in the light or in the dark), collect data over two weeks, and analyze the results graphically and verbally.

At the conclusion of the lesson, students will be able to:

  • Explain that respiration causes the loss of dry biomass (sugars)
  • Explain that photosynthesis causes the gain of dry biomass
  • Understand that carbon (carbohydrates) from carbon dioxide in the atmosphere makes up most of the dry mass of plants.

Albedo: How much of the sun’s energy gets absorbed?

Aug 292013
 

Celestia sun

Students will explore how different substances (air, water) and different colors absorb energy from the sun and warm up.  We will discuss what we already know about light energy and absorption, make predictions about what color of background paper will cause air and water to heat up faster, test our predictions by constructing boxes and collecting temperature data, analyze our data, and make conclusions about the implications for climate change.

At the conclusion of the lesson, students will be able to:

  • Graph data and interpret graphs
  • Draw conclusions from data collected during an experiment
  • Understand that the energy that powers almost everything on the planet comes from the sun, and that different substances can absorb more or less of that energy

rain forest loss

This lesson explores potential impacts that humans have on biodiversity as well as defining biodiversity, and exploring the potential positive impacts it has on humans and ecosystems. The lesson includes an outdoor activity consisting of choosing and visiting three sites that span a gradient of human impact. Using data collected during this activity, students will learn to use these data to calculate indexes of biodiversity. Some time will be spent discussing benefits/drawbacks to the methods employed. Data from the three sites will be compared to explore how humans tend to affect biodiversity. The topic of genetic biodiversity will also be covered with some examples where genetic diversity is important for humans and ecosystems.

At the conclusion of the lesson, students will be able to:

  • Assess levels of biodiversity in a given habitat
  • Discuss benefits and drawbacks of different methods for measuring biodiversity
  • Generate and test hypotheses about the levels of biodiversity in different ecosystems and regions

Rotten, but not forgotten

Aug 202013

Students often have misconceptions about the process of decomposition.  Students often explain decomposition as a purely physical process.  This introductory activity is meant to display the biochemical process of cellular respiration as it is occurring in microorganisms present in composting material. Cell respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available according to the following equation:

C6H12O6 + 6O2  –>  6 H2O + 6 CO2 + energy

All organisms oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Using the CO2 Gas Sensor and O2 Gas Sensor, students will monitor the carbon dioxide produced and the oxygen consumed by bacterial and fungi during cell respiration.

Conserving water and calculating your water footprint

Aug 202013
 

Conserve toilet water

Students will record their own water usage at their house for a week and estimate their daily water consumption. They will then be re-assigned to a different country where their water will be limited to the average usage of people in that location. The students will have to decide what they will use their allocation of water for, and then listen to how much other groups got to use and what they chose to use their water for. At the end, we will brainstorm why some locations have more water to use than others, and how that can lead to conflicts among different groups.

At the conclusion of the lesson, students will be able to:

  • Identify wasteful water practices
  • Explain differences in water usages in different areas
  • Understand the impact that water availability has on society

For this lesson, you will be participating in citizen science project started by Dr. Mary Gardiner at Ohio State University. Mary is a former graduate student in Entomology at Michigan State under the direction of Dr. Doug Landis. In 2009, approximately 100 Ohio gardeners will be collecting lady beetles on sticky traps and assessing populations of native and exotic species. All of the data will be compiled by Dr. Gardiner to assess the status of lady beetle populations across the state (http://ale.cfaes.ohio-state.edu/outreach/buckeye-lady-beetle-blitz-blbb).

We are excited at KBS to expand this study into curriculum material that can be used in area K-12 classrooms to improve biodiversity literacy and provide an opportunity for cross district collaborations and partnerships between KBS teachers and other teachers nationally and/or internationally.

Upon completion of this lesson, students will be able to:

  • Identify lady beetles to the species level by using handout materials
  • Use the three constraining principles from the MSP Strand to explain changes in biodiversity:
    1. Dispersal Constraints
    2. Environmental Constraints
    3. Community Dynamics

The Subliminal Significance of Soil

Aug 202013
 

Soil_profile

This lesson will build participants’ understanding of the importance of soil food webs by directly measuring carbon dioxide production due to soil organism respiration in samples from a variety of habitat types. Differences between annual and perennial crop field soils, as well as those from forests and lawns, will be used to highlight the important differences in carbon storage rates among these soil types. The main activity will be a titration lab determining the CO2 production from soil microcosms caused by microbial respiration. A class demonstration using Vernier probes will measure the same variable as a comparative method. A brief introduction to global carbon cycling and soil ecosystem components will precede the lab work.

Upon completion of this lesson, students will be able to:

  • Measure CO2 production from soil respiration with at least two methods.
  • Identify some of the major groups of organisms active in soil food webs, and their connection to global carbon cycling.
  • Explain how different plant communities affect the amount and type of organic carbon stored in their soils.
  • Predict how changes in human management practices of various communities are likely to affect soil carbon respiration rates in their soils.

Groundwater Conceptions and Processes

Aug 162013
 

Groundwater_flow

Teacher professional development lesson that can be modified for the classroom.

This lesson about groundwater includes an overview of three important ideas:  the scarcity of freshwater reservoirs available to us, what water looks like and how it flows in the ground, and how our land-use choices impact the availability of groundwater.  First is a demonstration of what percentage of the Earth’s water is available to us.  Incorrect conceptions of groundwater are very common, so we will use student drawings to understand where our students are starting when we introduce the idea of groundwater.  Finally we will demonstrate groundwater movement and storage using small groundwater models that teachers can use in their classrooms.

Upon completion of this professional development session, teachers will be able to:

  • Demonstrate the relative amounts of water on the Earth that is in various reservoirs
  • Pre-assess and anticipate students’ conceptions of groundwater
  • Model the water table and its relationship to surface water.
  • Model how groundwater contamination flows through the ground depending on the subsurface characteristics
  • Define and explain key terms related to groundwater processes: infiltration, porosity, permeability, aquifer

Gases matter!

Aug 162013
 

Soda_bubbles_macro

When understanding the states of matter, students often are able to understand those states they can see and work with the easiest (liquids and solids), and they are less able to reason about gases. Gas is all around us, but most students don’t think it weighs anything or matters very much. This exercise is designed to help students realize that gas has mass, and that the gas can add up and affect how the world works. We will weigh a balloon empty and full to see how the gas weighs something. We will watch a glass of soda lose mass as the bubbles leave. We will then compare the temperature within two clear containers (one with classroom air, and the other with the breath of a student) that are placed in the sun to see how particular gases (in this case carbon dioxide) can change the environment.

At the conclusion of the lesson, students will be able to:

  • Recognize that matter in the gas phase has weight
  • Describe how there can be different types of gases that can act differently (just like there are different types of liquids or solids)
  • Understand that even though we can’t see air, it is still all around us.
  • Operate a scale or balance to measure the weight of an object
  • Operate a thermometer to measure the temperature

Frogsicles: how frogs survive the winter

Aug 162013
 

Wood frog

How do frogs survive the winter when they’re frozen solid? Their heart may even cease to be beating, and yet they still bounce back just in time for some springtime hanky-panky. You will complete three short lab experiments to explore topics that help explain how frogs freeze over the winter: solute concentration, osmosis, and freezing point depression.

At the conclusion of the lesson, students will be able to:

  • Define and explain osmosis
  • Predict the relative freezing points of pure water, salt water, and sugar water
  • Understand that frogs have adaptations that help them survive the winter

Metrioptera_roeselii cricket

Students will explore their own level of assertiveness via a quick personality test to show that scores are not all the same in humans. Students will then do a manipulative simulation of her how individual variation can be maintained within a population by examining the survival and growth of bluegill that exhibit more aggressive and less aggressive foraging strategies. Students will do a behavioral lab experiment observing the behaviors of crickets in the presence or absence of food.  Students will then be guided in creating their own inquiry experiment. 

At the conclusion of the lesson, students will be able to:

  • Explain why intraspecific variation (individual variation within a population) can be maintained. (i.e. not always one best “adapted” trait)
  • Learn how zoologists study behaviors of animals in varying contexts (crickets in the presence and absence of food).
  • Create and carry out inquiry experiments regarding other cricket behavior.

Mussels

 

Students explore the effects of natural selection on populations with or without trait variation.  Students play a game with nuts simulating crab-mussel interactions, gather data from the game, analyze it by making figures, and draw conclusions about how an introduced predator could cause quick evolutionary change in only a few generations of the prey species.  Students answer questions about the three requirements for evolution by natural selection and discuss other examples of rapid evolution.

At the conclusion of the lesson, students will be able to:

  • List the three requirements for evolution by natural selection
    • Phenotypic variation in a trait
    • Relationship between that trait and fitness
    • The trait must be heritable
  • Determine whether evolution happened in a given situation

Comparison of Historical Lake Ice Cover Data From Three Lakes in Michigan and Wisconsin

Aug 152013
 

LakeIce

What evidence do scientists really have to support global climate change? Students will explore long term datasets on the duration of ice cover for three different lakes (Gull Lake, Fair Lake, and Lake Mendota). They will examine patterns of variation at different time scales to see the importance of long-term data as well as the importance of having multiple sources of support for scientific hypotheses (in this case, global climate change).

At the conclusion of the lesson, students will be able to:

  • Interpret data
  • Make inferences from trends or patterns in data
  • Make spatial and temporal comparisons of ecological systems
  • Explain how lake ice cover has changed due to global climate change on three lakes
