In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this activity, learners follow simple historical maritime recipes to cook up hardtack and swanky, and then compare the foods they eat to what was served on ships in the past.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

In this activity (page 4 of the pdf), learners build a model of a tide pool, using chicken wire, paper mache, and other craft materials.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity (page 5 of pdf), learners explore the relationships between the shape and structure of a shark's teeth and the food it eats, and then create their own shark tooth from clay.

In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
