Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

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

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

In this lab (Activity #1 on page), learners explore how we see color.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity learners will build a neighborhood out of blocks and cardboard.

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 accuracy and precision.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
