How Big Were the Dinosaurs?
Source Institutions
In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

Rover Races
Source Institutions
In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

Mystery Matter
Source Institutions
This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

Dirt Life
Source Institutions
After an interest-generating discussion about "dirt" and microbes, learners select and collect soil samples from a variety of locations (schoolyard, home, etc.).

Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

Using Chemical Change to Identify an Unknown
Source Institutions
In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

Tape Electroscope
Source Institutions
In this simple activity, learners create an electroscope by sticking two short pieces of magic tape together and then pulling them apart to find the sign of the charge on an unknown charged object.
Are you a Supertaster?
Source Institutions
In this activity, learners examine their tongue and taste buds.

Density Intensity
Source Institutions
In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

Foam Rocket
Source Institutions
In this activity, learners work in teams build and launch rubberband-powered foam rockets.
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

The Nose Knows!
Source Institutions
In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

Introduction to the Scientific Method
Source Institutions
In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

Rockets Away
Source Institutions
In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

Density Rainbow
Source Institutions
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Tree-mendous Plots
Source Institutions
In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.
