Digestion
Source Institutions
In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.
Crossing the Synaptic Gap
Source Institutions
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.
Matter on the Move
Source Institutions
Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.
Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
M&M's in Different Temperatures
Source Institutions
Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.
Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Formation of a Precipitate
Source Institutions
Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.
Changing the Density of an Object: Changing Shape
Source Institutions
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
Exercise and Memory
Source Institutions
This activity (page 1 of the PDF under SciGirls Activity: Exercise and Memory) is a full inquiry investigation into the effects of exercise on short term memory.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Evaporation
Source Institutions
This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.
Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Dogs and Turnips
Source Institutions
Learners turn over a random selection of cards from a larger set. From the words revealed, they try to determine the sentence represented on the larger set of cards.
Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.
Tiny Geyser Models
Source Institutions
In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.
Lava Layers
Source Institutions
In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.
