In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
