Number Sense and Computation: Money Counts
Source Institutions
In this math lesson, learners count and compare amounts of money less than or equal to one dollar.
Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
The Length of My Foot
Source Institutions
In this math lesson, learners explore the concept of using units to measure length. Learners first read "How Big is a Foot" by Rolf Myller and learn about units.
Saldo Island: An Unfair Game
Source Institutions
In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.
Sky Time: Kinesthetic Astronomy
Source Institutions
Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Castle Basics
Source Institutions
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha
Cloud Fun
Source Institutions
Learners complete a series of hands-on and investigative activities to explore cumulus clouds.
Animals in a Grassland
Source Institutions
In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.
Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.
Ocean Home: Swimming Fishes
Source Institutions
In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.
Spectroscope
Source Institutions
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
A Tree of Genetic Traits
Source Institutions
Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.
Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
Geometry and Spatial Relations: It's a Perfect Fit
Source Institutions
In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.
Food for the Brain
Source Institutions
In this activity, learners dissect a piece of pizza to learn about nutrients important for health.
Patterns and Relationships: The Magic Box
Source Institutions
In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Blimp Jet Challenge
Source Institutions
In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
Photosynthetic Pictures Are Worth More Than a Thousand Words
Source Institutions
This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
