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 observe how ice melts on wood and metal blocks, and they will draw conclusions about how heat conducts through different materials.
- 6–8

Grades:

In this activity, students build simple circuits to investigate the conductivity of solutions.
- 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 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 create a simple electromagnet using a nail, a battery, and copper wire.
- K–5

Grades:

In this activity, students will observe how ice melts on wood and metal blocks, and they will draw conclusions about how heat conducts through different materials.
- 6–8

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 gain an understanding of magnetic fields and magnetic forces.
- K–5

Grades:

In this activity, students carefully add drops of liquids to the surface of a penny to help them understand the concept of surface tension.
- K–5

Grades:

In this activity, students will examine the behavior of different types of solids when they are dissolved in water and explain those behaviors by examining the properties of the solids.
- K–5

Grades:

In this activity, students will create a simple model of Earth as a magnet.
- K–5

Grades:

In this activity, students will explore the relationship between angles of incident and reflected light and use this relationship to design and test their own periscopes in a classroom competition.
- K–5

Grades:

In this activity, students will use a ramp to launch a ball and strike a target.
- K–5

Grades:

In this activity, students construct a spectroscope and use it to observe the spectra of various sources of light.
