In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In this health activity (page 6 of the PDF), learners examine ingredient labels of packaged food products to find out what sugar ingredients they contain.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

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

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In the related activity called "Colors Collide or Combine," learners are intrigued by the apparent "line" that forms where colors from M&M coatings meet but do not mix.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.
