Source Institutions
This guide outlines how to plant a garden even if you don't have a yard!
Super Gelatin
Source Institutions
Can gelatin (like Jell-O ®) change the speed of light?
Phase Changes
Source Institutions
Learners observe a sealed test tube containing a small amount of solid stearic acid.
Planting with Precision
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.
Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.
Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.
Ice Fishing
Source Institutions
In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
Leaf Rubbings
Source Institutions
When was the last time you took a really close look at a leaf? In this activity, learners will use leaves and simple materials to make colorful leaf rubbings.
Collaboration via Slime Mold
Source Institutions
In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.
Extruding
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the process of extrusion used to produce pipes and wires in industry.
As The Stomach Churns
Source Institutions
In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre
Energy Choices Board Game
Source Institutions
This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.
Space Origami: Make Your Own Starshade
Source Institutions
In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
Build the Big Dipper
Source Institutions
Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.
Inverse Square Law
Source Institutions
In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.
Pocket Protractor
Source Institutions
In this activity, learners create angle-measuring devices--protractors--out of paper. Learners follow a series of steps to fold a square sheet of paper into a triangular Pocket Protractor.
Magnetic Free Fall
Source Institutions
In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.
Exercise in Creating Drawings for Field Notebooks
Source Institutions
Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.
A Slice of Apple Fly
Source Institutions
In this activity, learners build an instrument for catching and observing flies. Learners act as entomologists, attract flies into a jar using a slice of apple, and then observe the flies' behavior.
