In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

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

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

In this group or individual activity, learners are encouraged to watch birds near home or school—possibly where birds are nesting in a tree, pecking in a park, feeding from a feeder, or flying through

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

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 math lesson, learners explore probability.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

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.

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.

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

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

In this activity, learners will create a soil profile in a bottle. They will learn about the organic and inorganic matter found in soil and observe as it separates into layers in the bottle.

In this three-day lesson, learners identify two-dimensional shapes used in castle construction, create a castle collage using assorted shapes, and design tapestries using repeated patterns of color, s

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.

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 (located on page 6 of PDF), learners observe and reproduce the distinctive physical features (i.e. plates, sharp spikes, long necks, deep jaws, claws) of their favorite dinosaurs.
