Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Landing the Rover
Source Institutions
In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
Going for a Spin: Making a Model Steam Turbine
Source Institutions
In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
Construction Technologies: Construct the Strongest Bridge
Source Institutions
Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
Weather Stations: Storms
Source Institutions
In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.
Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.
Raceways
Source Institutions
In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.
Plants: Hanging Tough
Source Institutions
In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge
To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).
