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 (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners discover that atoms and ions of different metals will change places.

Learners investigate how drag affects the falling rate of objects.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
