In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

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.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

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

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

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.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners will build an instrument from common household items. Explore sound through vibrations created by your vocal chords and captured by an instrument.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.
