In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

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

In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this math lesson, learners explore probability.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.
