Mummy Magic
Source Institutions
Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
Damsels and Dragons
Source Institutions
In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Build a Giant Puzzle!
Source Institutions
In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
The Wander of Pollen
Source Institutions
In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.
Fuzzy Worms
Source Institutions
In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.
Swirling Milk
Source Institutions
In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.
Candy Chemistry
Source Institutions
In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.
Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.
Exploring Ultraviolet (UV) light from the Sun
Source Institutions
In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Hand Battery
Source Institutions
In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
Pixel Tube
Source Institutions
In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.
Recycling Paper
Source Institutions
In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.
Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Cutting it Down to Nano
Source Institutions
This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.
