Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

A printable weather station that will blow you away, this includes tools that little meteorologists can use to display their observations of daily weather conditions. There is a gauge where they can slide a pointer to show the...

Raise the temperature in your class with this hot film! Cartoon teens discuss thermal energy, the conservation and transfer of energy, three methods of heat transfer, conductors, and insulators. The publisher effectively packed every...

The instructor uses the formula for temperature to show how the variables can be moved around to solve a problem.

Students obtain remote sensing data to compare and contrast global biomass data with global temperature data.

Throughout this earth science exam, high-school geologists complete a series of multiple choice and short answer questions about the solar system, atmosphere, and earth system. This is an amazing test, as are all of the exams developed...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they compare the...

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

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...

High schoolers determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law...

Students use an on line simulation to produce ammonia using Haber's process. In this Haber's process lesson plan, students use a spreadsheet to manipulate the pressure, temperature and catalysts used in the production of ammonia. Their...

Students explore how to read a thermometer and what the instrument does. They practice measuring hot and cold objects and discuss changes in the weather based on temperature.

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

See the direct relationship between pressure and temperature using these classic science toys. As individuals hold the glass bulb, the liquid inside reaches it's boiling temperature, which is just a bit above room temperature. As the...

Weather watchers are introduced to temperature scales using step-by-step animated slides. The Home set explains the Fahrenheit scale on a thermometer, while the Watch Out! set introduces Celsius. A Try It! tab contains two guided...

From temperature and mass, to length and volume, there are many different types of measurement. Expose young learners to a variety of measurement tools using this slide show of real-life pictures. Go through the presentation one image at...

What a terrific way to explore temperature! Little scientists can use this resource to make their own large thermometer and measure hot and cold liquids. They can then come up with their own experiment ideas or discuss how it might be...

Use this demonstration to help your class understand convection currents. Learners put food coloring in bottles, one with hot and the other cold water, and see what happens. This is a terrific way to make this idea come alive. Once they...
