Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.
Kid Machine
Source Institutions
This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.
Spider Glider
Source Institutions
In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.
Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.
DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
Rubber Blubber Gloves
Source Institutions
In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.
Bark Beetle Infestation Investigation: Estimation and Pheromones
Source Institutions
This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.
Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.
Test Density with a Supersaturated Solution
Source Institutions
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
Speed, Eggs and Slam!
Source Institutions
In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
