In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

Learn about friction and kinetic energy with this cool spinning toy.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

Computers store drawings, photographs, and other pictures using only numbers. Through this activity, learners decode numbers to create pictures using the same process that computers use.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners will reuse plastic bags in an interesting way.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

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

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

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

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
