In this activity, learners investigate the properties of different types of balls.

Learners play the role of materials engineers as they test the flexibility of different materials.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

Historically, sea floor mapping (bathymetry) was done by soundings.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this activity, learners discover how NASA engineers develop experimental aircraft.
