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.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this activity, learners conduct tests for proteins, glucose, and starch.

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

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.

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

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

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 stain fabrics--on purpose!

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 activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

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