Mermaid's Purse
Source Institutions
In this activity (page 2 of pdf), learners craft a model of a skate egg case and come to understand that cartilaginous fish such as sharks and shakes employ reproductive strategies that differ from th
Earthquake Science: Soil Liquefaction
Source Institutions
This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.
Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
Straws and Pins
Source Institutions
In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.
The Model Neuron
Source Institutions
In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.
Full of Hot Air: Hot Air Balloon Building
Source Institutions
In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.
Old Faithful Plumbing Investigation
Source Institutions
This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.
Invent an Insect
Source Institutions
In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.
Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.
Straws and Airplanes
Source Institutions
Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.
Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Edible Earth
Source Institutions
In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Constellation Chamber
Source Institutions
Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Gravity Launch
Source Institutions
In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.
Inside Out
Source Institutions
Learners draw and cut out shapes of organs from construction paper. Then they attach these organs to the body of one learner to make a life-sized map of all the internal organs.
