Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

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

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this activity, learners control the (apparent) size of a hole with their brain.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this activity, learners consider how oil spills behave in the ocean and what impact they have on marine wildlife.

In this activity, learners explore the process of condensation.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity, learners create their own experiment and test which of 4 mixtures of household chemicals turn pennies green over 5 days.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity on page 7 of the PDF (Get Cooking With Chemistry), learners conduct an experiment to get an idea of how cheese is made.
