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.
Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Inflate-a-mole
Source Institutions
In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.
Density Rainbows
Source Institutions
In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.
Energetic Musical Instruments
Source Institutions
Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.
Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.
Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.
Keeps on Pumpin': Your Heart
Source Institutions
In this activity, learners explore the great pump in their chests--the human heart!
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
