Grades:

In this activity, students will make sound three ways: by blowing across the top of a bottle, tapping a glass, and running a finger around the rim of a glass.
- K–5

Grades:

In this activity, students will test and observe the bouncing properties of different types of balls (softball, basketball, golf ball, playground ball, volleyball, beach ball, ball of paper).
- K–5

Grades:

In this activity students will experiment with how far sound travels naturally, as compared to how far it travels with satellite amplification.
- K–5

Grades:

In this activity, students will use paper chromatography to separate the colors in the dyes used to color candies.
- K–5

Grades:

In this activity, students will build a Cartesian diver and discover how compression and changes in density cause the diver to mysteriously move up and down.
- K–5

Grades:

In this activity, students will construct color wheels and spin them to see that light colors combine to form new colors.
- K–5

Grades:

In this activity, students build simple circuits to investigate the conductivity of solutions.
- K–5

Grades:

In this activity, students will test the effectiveness of different parachute designs.
- K–5

Grades:

In this activity, students will gain an understanding of how a simple hovercraft uses the forces of motion to move.
- K–5

Grades:

In this activity, students will use a ramp to launch a car and reach a finish line.
- K–5

Grades:

In this activity teams design, build, and test paper helicopters to observe a relationship between blade surface area and descent rate.
- K–5

Grades:

In this activity, students will design their own miniature golf hole and then determine the path along which a ball would travel to score a "hole-in-one."
- K–5

Grades:

In this activity, students will create their own insulating "ice chambers" and then test them against the models made by their classmates.
- K–5

Grades:

In this activity, students will gain an understanding of how sound waves travel through different media by building a sound transmission device.
- K–5

Grades:

In this activity, students will create a simple electromagnet using a nail, a battery, and copper wire.
- K–5

Grades:

In this activity, students will compare two forces of energy on the motion, velocity, and direction of an object.
- K–5

Grades:

In this activity, students will gain an understanding of the engineering design process by designing and observing different containers that slow down the process of heat transfer.
- K–5

Grades:

In this activity, students will use a laser pointer and flat mirrors to explore the law of reflection.
