In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

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

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
