In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this activity, learners create a cylindrical mirror to see themselves as others see them.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

In this demonstration, learners explore the thermal properties of rubber. Learners investigate whether a rubber band contracts or expands when heated.
