Fizzy Nano ChallengeAdd to list Details
This lesson focuses on how materials behave differently as their surface area increases.
Gravity in Action
Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.
The Boxes Go Mobile
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
Soap Bubble ShapesAdd to list Details
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
The Power of Words
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
Modeling Limits to Cell SizeAdd to list Details
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Surface Area and Soda Geysers
This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.
Bubble TrayAdd to list Details
In this activity, learners use simple materials to create giant bubbles.
Kool ColorsAdd to list Details
Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.
Number Sense and Computation: Soak It Up
In this math lesson, learners compare products to determine the best product.
Membrane Permeability with BeetsAdd to list Details
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
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.
Brick Drop ChallengeAdd to list Details
In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.
Desert Water Keepers
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
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.
Rate of Solution Demonstration
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
Measuring and Protecting Skin
In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.
Exploring at the NanoscaleAdd to list Details
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
