Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.
Racing M&M Colors
Source Institutions
Learners design their own experiment to determine which M&M color dissolves the fastest in water.
Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Any Year Calendars
Source Institutions
This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.
Make a Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.
Scale Model of Sun and Earth
Source Institutions
In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.
Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.
Gravity and Muscles
Source Institutions
In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Super Golf Tower
Source Institutions
In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.
Home Water Audit
Source Institutions
This activity offers learners and their families several ways to raise their awareness together about home water.
Active Graphs
Source Institutions
In this activity, learners track their movements with jumping and leaping graphs.
Drinking Straw Pulse Measurer
Source Institutions
In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Double or More
Source Institutions
Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?
Atmospheric Collisions
Source Institutions
In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.
Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
