That Sinking Feeling
Source Institutions
In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
Tree Investigations
Source Institutions
In this activities, learners head outside and investigate trees through bark rubbings. Learners will need paper, a pencil, and some unwrapped crayons to create them.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Daffy Density
Source Institutions
In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.
Reaction Time
Source Institutions
In this activity, learners explore reaction time and challenge themselves to improve their coordination. Do you want to move faster? Catch that ball that you never seem to see in time?
Organ Pipe: Get Bach to the fundamentals
Source Institutions
If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.
Zoom-A-Rang
Source Institutions
In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Monster Evolution
Source Institutions
In this online activity, learners create monsters and see how they survived when released into the wild.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
Exploring Size: Measure Yourself
Source Institutions
In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.
Color Vision
Source Institutions
In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.
Mind-Reading Magic
Source Institutions
In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.
Stethoscope
Source Institutions
Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!
Sink or Swim?
Source Institutions
Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.
Shark Cart
Source Institutions
In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).
Binary Challenge
Source Institutions
In this activity, learners cut out 5 paper cards and label them with 1, 2, 4, 8, or 16 dot(s) to explore binary digits.
When is a Glass of Water Really Full?
Source Institutions
In this activity, learners see how many coins they can add to a full glass of water before the water overflows.
Scale Model of Sun and Earth
Source Institutions
In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.
Mechanical Madness
Source Institutions
In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.
