Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Having a Gas with Cola
Source Institutions
In this activity, learners measure the amount of carbon dioxide in a carbonated drink.
Bernoulli Levitator
Source Institutions
Demonstrate the Bernoulli Principle using simple materials on a small or large scale.
A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.
Gas Model
Source Institutions
This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.
Stability of Egg White Foams
Source Institutions
In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
Light Soda
Source Institutions
In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.
Conversation Piece
Source Institutions
Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.
Condiment Diver
Source Institutions
In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.
Sizing Up Temperature
Source Institutions
In this activity, learners explore Charles' Law in a syringe.
Liquid Crystal Thermometers
Source Institutions
In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Fog Chamber
Source Institutions
In this weather-related activity, learners make a portable cloud in a bottle.
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
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.
