Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.
Pre-School Ball Run!
Source Institutions
In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.
Heavy Lifting
Source Institutions
In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Jumpin' the Gap
Source Institutions
In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
Cool It!
Source Institutions
Learners make a refrigerator that works without electricity. The pot-in-pot refrigerator works by evaporation: a layer of sand is placed between two terra cotta pots and thoroughly soaked with water.
Spectroscope
Source Institutions
In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.
Properties of Metals
Source Institutions
In this activity, learners explore the properties of metals at four stations. The stations include A) Magnetism and Breakfast Cereal; B) Conductivity of Metals; C) Alloys; and D) Metal Plating.
Measurement: It Takes Ten
Source Institutions
In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.
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.
Good Vibrations
Source Institutions
This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.
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.
Gel Electrophoresis of Dyes
Source Institutions
In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.
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.
