Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho
Oboe? Oh, Boy!
Source Institutions
In this activity, learners create a straw oboe to explore sound and pitch.
Build a Raft
Source Institutions
In this activity, learners explore density and buoyancy as they design and construct rafts.
Protect That BRAIN!: Mr. Egghead
Source Institutions
This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.
The Great Fossil Find
Source Institutions
On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.
Loony Balloons
Source Institutions
In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.
Super Spinners
Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.
Constellation Tubes
Source Institutions
In this activity, learners will create their very own constellation.
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.
Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
Weightless Water
Source Institutions
In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.
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.
Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.
Making Map Projections
Source Institutions
In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.
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
Big Bubbles
Source Institutions
How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.
Medical Mystery
Source Institutions
This activity (on pages 15-23) combines interactive role-playing and graphing to introduce learners to the health affects of pollen.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.
Pop Rockets
Source Institutions
In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.
