This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.

In this activity, learners explore sound by constructing their very own bagpipe instrument.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity, learners build styrofoam boats powered by twisted rubber bands.
