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.
Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
Rate of Solution Demonstration
Source Institutions
In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
Potato Power
Source Institutions
Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.
Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.
Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
Viral Packaging
Source Institutions
In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.
Nano Waterproofing
Source Institutions
This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
Number of Mentos vs. Height: Soda Geyser Series #5
Source Institutions
In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.
