In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

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

In this engineering activity, learners design their own board games.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners design a bungee jump for an egg using nylon stockings.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners build a seesaw powered by magnets.
