Fizzy Nano ChallengeAdd to list Details
This lesson focuses on how materials behave differently as their surface area increases.
Perspectives: Powers of 10
In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.
Skin, Scales and Skulls
In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.
Rate It: Working With Zero and Negative Numbers
In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.
Incredible Shrinking ShapesAdd to list Details
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
Modeling Limits to Cell Size
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Heavyweight Champion: JupiterAdd to list Details
In this activity, learners confront their perceptions of gravity in the solar system.
Be a Scanning Probe MicroscopeAdd to list Details
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano
The Pull of the PlanetsAdd to list Details
In this activity, learners model the gravitational fields of planets on a flexible surface.
Do Your Own Dig
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.
Dunking the PlanetsAdd to list Details
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Build a Solar SystemAdd to list Details
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
Construction and DestructionAdd to list Details
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.
Life Size: What's in a microbe?Add to list Details
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
Proportionality: The X-Plane Generation
In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.
Castle BasicsAdd to list Details
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha
In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.
Small Snails, Enormous Elephants
This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.
Animals are Amazing!
In this activity, learners use measurement concepts to make models of what their body parts might look like if they were a snake or a chameleon.
Scaling CubesAdd to list Details
In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.
