In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

Can gelatin (like Jell-O ®) change the speed of light?

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.
