What's the Difference between Weather and Climate?
Source Institutions
In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

Straw Pipes
Source Institutions
Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.
Pattern Sticks
Source Institutions
In this activity, learners compete to be the first to win twenty counting pieces. First, learners draw patterns on only one side of four craft sticks.

Estimation Exploration
Source Institutions
In this "Sid the Science Kid" activity from Episode 103: Enough With the Seashells!, learners practice estimating numbers of objects (like shells) and then check their estimates by counting.

Is it a Fair Game?
Source Institutions
In this math activity, learners play two versions of a card game and decide what makes a game fair. Learners also practice addition and subtraction skills.

Toma Todo
Source Institutions
In this activity, learners play a traditional Mexican game of chance with a twist. Learners take turns spinning a special "Toma Todo" top.

Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
Race to the Dollar
Source Institutions
In this math activity, learners play a card game to practice adding coins quickly, just like a banker. First, learners create coin cards. Next, the cards are dealt to each player.

Circle Logic
Source Institutions
This is a deceptively simple game to teach strategy, planning, and pattern analysis. In this game, learners take turns removing tokens from a board, and develop a plan to take the last piece.

Color Spy
Source Institutions
In this activity (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.

Symmetry Fold-Overs
Source Institutions
In this math activity, learners experiment with the concept of symmetry.

Moving Model Glacier
Source Institutions
In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.
Work for Your Money
Source Institutions
In this math activity, learners earn "money" by completing simple tasks. Learners complete as many "jobs" as possible in a set amount of time.

How High (or Low!) Can You Go?
Source Institutions
In this math activity, learners play a game using their number sense to make the highest or lowest number possible. Use this activity to explore place value and/or decimals.

Topographic Investigation: Map an Underwater Surface
Source Institutions
In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

Symmetry of Butterfly Wings
Source Institutions
In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

Magnetic Sensory Bottles
Source Institutions
In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

Weight in Space
Source Institutions
In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In Proportion
Source Institutions
Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.
