Fizzy Nano ChallengeAdd to list Details
This lesson focuses on how materials behave differently as their surface area increases.
Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.
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.
Separation AnxietyAdd to list Details
In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.
In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .
Heavyweight Champion: JupiterAdd to list Details
In this activity, learners confront their perceptions of gravity in the solar system.
The Pull of the PlanetsAdd to list Details
In this activity, learners model the gravitational fields of planets on a flexible surface.
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
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.
Big and Little Cups
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.
How Big is SmallAdd to list Details
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Find Someone: Use Math to Learn About Friends
Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?
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.
In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.
Supersize That Dinosaur
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.
Sniffing for a Billionth
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.
