Watercolor
Source Institutions
In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.
Bag Pipe
Source Institutions
In this activity, learners explore sound by constructing their very own bagpipe instrument.
So Many Parts
Source Institutions
In this online Flash game and spacewalk mission simulation, learners are challenged to repair parts of a space station while balancing their oxygen and fuel use carefully.
Stick to It: Adhesion II
Source Institutions
Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
Resistance is Useful
Source Institutions
Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint.
Apples with Appeal
Source Institutions
In this activity, learners investigate why apples turn brown. Learners discover that lemon juice interferes with the reaction that causes the browning.
Exploring Forces: Gravity
Source Institutions
In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
Screaming String Thing
Source Institutions
In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.
Seeds: Roots and Shoots
Source Institutions
In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.
Design a Parachute
Source Institutions
After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.
Water on the Move: Wind and Waves
Source Institutions
In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).
Parachute Design
Source Institutions
In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.
Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
Butterflies in Space
Source Institutions
The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
Nature Drawing
Source Institutions
In this family or group activity, learners create a nature journal by visiting a local nature center or backyard, observing creatures in their natural habitats, and sketching what they see.
Protein Factory
Source Institutions
In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.
What's in a Penny?
Source Institutions
In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.
Marble Mazes
Source Institutions
In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.
Water Ways
Source Institutions
In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.
