How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Water Exploration Station
Source Institutions
In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

Sinking Water
Source Institutions
In this experiment, learners float colored ice cubes in hot and cold water.

Jet Propulsion
Source Institutions
In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

Ocean Home: Swimming Fishes
Source Institutions
In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

Spectroscope
Source Institutions
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

Knowing North: Understanding the Relationship between Time and the Sun
Source Institutions
This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.

Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

A Universe of Galaxies: How is the Universe Structured?
Source Institutions
This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies.

Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.

Match Rock
Source Institutions
In this activity, learners try to figure out who has their matching rock type by reading a description of their rock (no talking!).

Shower Estimation
Source Institutions
In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

Ramp it Up
Source Institutions
In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

Tomb Mapping
Source Institutions
In this activity, learners examine the culture and history of the tomb site.

Counting Your Lucky Stars
Source Institutions
In this activity, learners sample a star field to estimate the number of stars in the universe.

Looking Back Through Time
Source Institutions
In this activity, learners create their own archaeological profiles.

Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
