Monitoring Water Pollution with Invertebrate Indicator Species
Healthy invertebrates mean healthy ponds. An outdoor activity has scholars collect samples of invertebrates from local lakes or ponds. They identify and count different species and use the information to estimate the level of pollution...

Investigating the Effect of Temperature on the Activity of Lipase
How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Controlling Body Mass
Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

A Model for Natural Selection- Spaghetti Worms
Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

Observing Earthworm Locomotion
One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...

Elastic Recoil in Arteries and Veins
A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Investigating Factors Affecting the Breathing Rate of a Locust
Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

Investigating the Effect of Concentration of Blackcurrant Squash on Osmosis in Chipped Potatoes
Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Investigating an Enzyme-controlled Reaction: Catalase and Hydrogen Peroxide Concentration
Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Investigating the Effect of Minerals on Plant Growth
How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...

Monitoring the Body's Reaction to Stress
When stressed, do you prefer the fight or flight response? Scholars observe, measure, and identify the body's response to stress using a well-researched methodology. They learn about the autonomic nervous system, hormones, and more.

Recycled Paper
Sixth graders keep track of the amount of paper they consume on a daily, weekly, and monthly basis. The goal of the lesson is to have them all find ways to reduce the amount they use. Everyone creates recycled paper from old newspapers...

Appearances Are Deceiving
Young scientists study creeks around their area to see how clean the water really is. One way to tell is by the invertebrate populations that are present. This lesson introduces a game which learners simulate a variety of species found...

Biodiversity in Your Backyard!
Take your enthusiastic ecologists outdoors to explore the biodiversity right in their own schoolyard! In preparing for this activity, it may be worthwhile to research websites with local flora to help in the plant identification portion.

Waste Audit
Students engage in a lesson that is concerned with the concept of mental math. They perform calculations as following: recognizing a half, three quarters, and tenths. Students are also challenged to extend skills to making calculation...
