Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

Playing with Parachutes
Source Institutions
In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

Flat Flashlight
Source Institutions
In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

What Trickles Down?
Source Institutions
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

DIY Pasta Rover
Source Institutions
In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

Circuit Board
Source Institutions
Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

Exploring Structures
Source Institutions
This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

Exploring the Nanoworld with LEGO Bricks: Structures at the Nanoscale
Source Institutions
In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.

Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

ROV Races
Source Institutions
In this activity, learners will work together to create a program to navigate a Remotely Operated Vehicle (ROV) through an obstacle course.

Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

Forces at the Nanoscale: Nano Properties of Everyday Plants
Source Institutions
This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Burst a Bubble
Source Institutions
In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.
