Funded by The Healthineers Fund of the Siemens Foundation

Grades:

In this activity, students create an acid-based indicator using red cabbage extract.
- 6–8

Grades:

Description: Students consider the benefits and tradeoffs of using credit and learn about the role interest plays in using credit cards. Then, they create an equation that describes the length of time it takes to pay off a debt.
- 9–12

Grades:

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

Funded by The Healthineers Fund of the Siemens Foundation

Grades:

In this activity, students will explore the five senses by performing a variety of activities.
- K–5

Grades:

In this activity, students will build a simple solar cooker, make observations and qualitatively describe the melting rate of a piece of chocolate in the cooker.
- 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

Funded by The Healthineers Fund of the Siemens Foundation

Grades:

In this activity, students will construct a model ear to learn how different materials transmit sound.
- K–5

Grades:

Working in groups, students will select a city and then use U.S. government census data to develop an algebraic relationship between time and population size.
- 9–12

Grades:

In this activity, students will make their own weather station.
- 6–8

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 excavate a box containing several layers of sediment.
- 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 use a stream table to model the processes of erosion and streambed formation.
- K–5

Funded by The Healthineers Fund of the Siemens Foundation

Grades:

In this activity, students will explore the nature of human hearing by attempting to determine the location of coins dropping at different locations in a room.
- K–5

Grades:

In this investigation, students will design three different circuit arrangements with a switch capable of lighting a small light bulb. They will use the results of this investigation to determine the best configuration for wiring holiday lights.
- 9–12

Grades:

In this activity, students will use a variety of materials to attempt to clean up a simulated oil spill.
- 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.
