Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
Pressing Pressure
Source Institutions
In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.
Capturing Homemade Microgravity
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.
Egg Osmosis
Source Institutions
Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.
See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
Magnets are Marvelous
Source Institutions
In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.
My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.
Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
Shocking Fruit
Source Institutions
In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.
Jar Races
Source Institutions
In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.
Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
Exploring How Robots Move
Source Institutions
In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.
Black Magic (Color Chromatography)
Source Institutions
With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.
Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi
Double Dutch Distractions
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.
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.
Guar Gum Slime
Source Institutions
In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.
