Animal Nutrition
Use this great overview to give information on all aspects of nutrition. By working their way through this PowerPoint, students review a lot of information about the digestive process. Students read many facts on a number of...
Curated OER
The good microbes
The question posed for the class to consider; What would decay and what would not? They read the short passage on decomposition and microbes, then mark the items that would decay after a two-week period. A scientific investigation idea...

The Scientific Method
Young scholars examine the Scientific Method. They will discover the value in being observant, organized, and thorough with regard to science. They will also explore how these traits can serve them well in other areas of life.
Curated OER
Measuring the Effects of Gravistimulation on Plants
Students conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.
Curated OER
Comparing Roots After Rotation of Ninety Degrees
Young scholars conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.
Curated OER
Observing the Growth of a Maize Root
Students conduct an experiment in order to observe the typical downward growth of a maize root. They become familiar with the root's growth patterns to use as a control for comparison in other experiments.
Curated OER
Root Caps and the Effect on Gravity Sensing
Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.
Curated OER
De"compost"ition
Students develop an understanding of the decomposition process and the parameters which influence the rate at which it occurs.
Curated OER
Stream Quality Assessment
Young scholars investigate many of the factors that affect water quality. They take measurements and water samples at a local stream and evaluate the health of their community's watershed. They write a report detailing their findings.
Curated OER
Should Soil Be Sterile?
Learners determine if the sterilization of topsoil is beneficial to seed germination and plant growth. They grow plants alongside control groups, make and record observations of plant growth and measure plant biomass.
Curated OER
Plant Diversity and Distribution
Students construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.
Curated OER
Dating a Volcanic Eruption
Young scholars discover how to "read" tree rings to determine the date of a volcanic eruption and the effects an eruption has on plant growth. After a lecture/demo, students utilize a worksheet imbedded in this plan to date an eruption.
Curated OER
The Food Connection
Learners examine the connection between the foods on the food pyramid and agricultural products. They identify the food groups, discuss foods from each group, complete two handouts, and construct a desktop food pyramid, placing foods in...
Curated OER
Where the Buffalo Roam
Second graders explore what life in the Chicago area was like hundreds of years ago. They discuss how settlers impacted the environment, and why there are no longer herds of buffalo in the Chicago area today. They read an article and...
Curated OER
Fire Fighting
Students consider the effects of a wildfire on prairie life. They explore the ways that plants regenerate after a fire and create fictional plants that have adapted specifically to the prairie environment. They share models of their plants.
Curated OER
Food Pyramid
Students construct food pyramids by painting shoe boxes and using them to respresent different food groups. They cut out and paste pictures of the respresentative foods for the groups on the box sides. They compare their diets to the...
Curated OER
Hierarchy Theory and Biotic Hierarchy
Learners examine the hierarchy theory and biotic organization by playing a teacher-created card game matching groups of items, such as organelles, in suits of four. They discuss the reasons for their hierarchical organization of the...
Curated OER
Soil Porosity, Moisture Content, pH, and Density
This lab activity does not have to be done with AP environmental scientists. It can also be done with middle to high school earth scientists. The procedures aren't complex. Learners determine the density of dry and wet sand in order to...
Curated OER
Worms, Nature's Recyclers!
Young scholars study what worms need to survive in different environments. They study how worm composting improves soil and reduce waste. They discuss composting techniques and present a puppet show about a worm's life.
Curated OER
Lesson 2: Timber Harvesting Methods and Logging Methods
Whereas very few learners study this topic, this lesson plan is written well! An organized and detailed teaching outline explains thinning, clearcutting, seed tree, and shelterwood methods of harvesting timber. Beautiful diagrams can be...
Curated OER
Cyanobacteria Races: Cyanobacteria Motility Experiment for a Classroom
Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.
Curated OER
Soil's Secret
Students examine two types of soils in their area. They identify its texture and permeability to determine its origin. They share their results with the class.
Curated OER
Food Choices The Pyramid Way
Young scholars develop skills in making nutritionally-sound food choices. Keeping a food diary, they analyze their food intake using the food pyramid as a guide. Students identify and explain the relationship of nutrition to personal...
