Mystery Matter
Source Institutions
This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.
Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.
Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.
Foam Rocket
Source Institutions
In this activity, learners work in teams build and launch rubberband-powered foam rockets.
Balsa Towers
Source Institutions
Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
Introduction to the Scientific Method
Source Institutions
In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.
Density Rainbow
Source Institutions
In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.
Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
Forward Thinking
Source Institutions
In this activity, learners create their own weather forecast map.
Gel Electrophoresis of Dyes
Source Institutions
In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.
Protein Bracelets
Source Institutions
In this activity, learners use beads, which represent amino acids, to create protein bracelets. Learners examine the relationship between amino acids and proteins.
Print Hints
Source Institutions
In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.
Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
Gravity and Falling
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.
Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
Whale Cart
Source Institutions
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).
