Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore accuracy and precision.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this mechanical engineering activity, learners design shadow puppets with moving parts and use them to tell stories.
