As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Make a Wire Critter That Can Walk on Water
Source Institutions
In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
Solving Linear Equations: The Yo-Yo Problem
Source Institutions
In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
Mars from Above: Viewing Volcanoes
Source Institutions
In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.
Average Names
Source Institutions
In this activity, learners compare the number of letters in the names of the people in their families or group of friends.
Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.
Tissue Paper Spray Art
Source Institutions
In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.
M&M's in Different Sugar Solutions
Source Institutions
In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.
The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.
Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.
Scented Dough
Source Institutions
In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
Making Mosaics
Source Institutions
In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.
Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.
Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Underwater Hide and Seek
Source Institutions
In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.
The Water Cycle
Source Institutions
Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.
