In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners conduct tests for proteins, glucose, and starch.

In this multi-faceted game (on pages 25-35), learners recreate what happens to creatures in the Brazilian rain forest as they grow from egg to adult—especially those that use fallen, empty Brazil nut

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.
