This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity, learners will build the highest tower they can out of recycled materials.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

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

In this activity, learners investigate the history and development of agricultural biotechnology.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
