Students, in groups, create experiments to predict and prove what a change in pressure can do to objects exposed to the change. They use AppleWorks to write their hypotheses and the steps they need to conduct the experiment.

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

If you want your young chemists to fully grasp the behavior of gases, here is an all-inclusive lesson plan. It provides handouts of detailed instructions for three laboratory activities, assessment reccomendations, and a list of...

Students observe what happens as crayon shavings are melted and/or pressed together. They compare this to the process some rocks go through as they are heated and compressed naturally on earth.

Spark an animated debate in your class! Young adults consider some of the fads or trends that are prevalent at their school, as well as their own level of participation in them. Just how much of a role does popular culture play in their...

Although it requires a little extra preparation the first time you use this geyser demonstration, it can be used repeatedly once it has been constructed. This demonstration is useful in showcasing how heat leads to increased pressure and...

Everyone knows that eggs break easily. Or do they? Give learners an egg-citing chance to try crushing an egg with one hand, and they likely will fail, due to the pressure being evely distributed around the shell. Life science learners...

Thorough instructions are given to guide you through making a demonstration hydraulic pump from two plastic soda bottles. After using the resource to teach your class about Pascal's and Bernoulli's principles, turn them loose in groups...

Push a straw through a potato using air pressure. This is a good for modeling how air pressure works.

Students explore their neighborhoods to collect a variety of rocks that are compared for color, texture, and size. This leads to a inquirey into the parts of the Earth and the type of rocks that conctitute its crust.

Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...

In this gases worksheet, students find temperatures, pressures, densities and volumes of gases using the gas laws. They also fill in the blanks about a "wet dry ice lab" done in class and they graph the data from a "Boyle's Law Lab" to...

For this ideal gas law worksheet, students solve eighteen problems using the ideal gas law to solve for moles of gases, temperature of gases, pressure of gases or volumes of gases.

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized lesson...

Pairs of space scientists or junior physicists construct and deploy antacid-powered rockets. Through this activity, they observe Newton's Laws of Motion. The plan is detailed and well-organized. Resource links include professionally...

A wonderful set of word problems about gas systems requiring volume, pressure, or molar calculations. The nine problems are phrased in different ways to provide different sets of variables, and consequently, calculations needed. This...

If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...

Using chalkboard animation, this video thoroughly explains the three empirical gas laws: Avogadro's, Boyle's, and Charles'. Use it as an introduction when teaching young chemists about the properties and behavior of gases.

Show your learners how to make a Styrofoam cup shrink. Steve Spangler demonstrates how you can use a pressure cooker to create a miniature Styrofoam cup. This could be used to kick off a variety of lessons focused on chemical reactions...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Liquids are lovely, and this slide show pays them the honor due! It introduces physics participants to the behavior and characteristics of liquids, buoyant force, Archimedes' and Pascal's principles, and the amazing properties of water....
