Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.

In this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

Using indirect methods, learners determine the shape and size of a piece of carpet hidden under a piece of plywood.

In this activity, learners discover how NASA engineers develop experimental aircraft.

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
