In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.

In this science/art activity, learners create an insignia or emblem for a planet exploration mission.

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

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners use sound to figure out, or infer, the position of objects. Learners create a maze inside a shoebox with blocks of wood.

In this math game (Page 15 of the Dining Out! PDF), learners figure discounts and/or profit increases for various food totals. Learners add decimals to $100.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity (on pages 26-33), learners play parasitologists, solving several "mysteries" about people who got sick from various parasites. In teams of four, each member solves one mystery.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.
