Up, Up, and Away
Source Institutions
In this math lesson, learners explore the real world meaning of slope. Learners conduct a balloon experiment in which they measure the circumference and flight time of deflating balloons.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Invisible Investigations
Source Institutions
Using indirect observational methods, learners distinguish between charged and uncharged objects.
Drip, Drop, Drip, Drop
Source Institutions
In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
Challenge: Microgravity
Source Institutions
In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod
Build an Overhead Projector Spectroscope
Source Institutions
This activity guide includes instructions for building a spectroscope using a standard classroom overhead projector.
The Ups and Downs of Thermometers
Source Institutions
In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.
Create a Mangrove Tree
Source Institutions
In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.
Floating and Falling Flows
Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.
Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.
Fishy Observations
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.
Bouncing Yo-Yo
Source Institutions
In this activity, learners build unique yo-yos, which spin round and round without moving up and down.
Bean-Counter Evolution
Source Institutions
In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).
Avi's Sensational Salt Dough
Source Institutions
In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.
Telescope Treasure Hunt
Source Institutions
This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.
Cleaning Water with Dirt
Source Institutions
In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.
Energetic Musical Instruments
Source Institutions
Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.
Testing Vitamin C: Chemistry's Clear Solution
Source Institutions
In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.
Scent Tag
Source Institutions
In this matchmaking activity (on page 2 of the PDF under GPS: Animal Scent Activity), learners will each have a scented cotton ball taped to their shoulder. The scent (e.g.
Lung Model: Make a Lung and Diaphragm
Source Institutions
By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.
