Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to repre

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

In this activity, learners explore center of gravity, or balance point, of stacked blocks.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.
