Diffusion rates change with differences in temperature. See it happen through a simulation that allows scholars to explore the rates of diffusion at five different temperatures. It also allows young scientists to trace the movement of a...

All together now! Physical science pupils observe the effects of temperature and amount of substance on pressure and volume of a gas. The interactive resource guides learners through the Combined Gas Law, where they observe changing...

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

Young scholars estimate, calculate, and count back the amount of change needed from purchases made during small group activities.

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Learners discover the history of hot air balloons by watching one ascent.  In this physics instructional activity, students utilize a Montgolfier Hot Air Balloon from an earlier instructional activity and record the temperature,...

Open with a discussion on weather and climate and then explain how tree rings can provide scientists with information about the earth's past climate. Pupils analyze graphics of simulated tree rings from various US locations for the...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

Students explore Earth science by participating in a weather identification activity. In this scientific instrument instructional activity, students identify several weather related tools such as the weather vane, thermometer and rain...

Don't be resistant to physics! A simulation shows classes how a resistor works. Change the battery voltage and resistance to show how this affects the flow of electrons. Temperature and amps measurements are shown for the system as...

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Students make fudge after reading fractional values in recipes and finding equivalent fractions to those presented in the recipes. They study measurement abbreviations.

Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students determine where to buy the heaviest earthworms as they study invertebrates. They create a double bar graph of the results of the weight data.

Students play the role of scientists testing for water quality in the area. In this ecology instructional activity, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection...

How many jackets do you need to stay warm and climb Mount Everest? An informatie resource covers the topic of Mount Everest, the resource helps young scientists discover the difference between climate and weather. Activities include...

In a nose-cone to nose-cone competition, which rocket will prevail? Teams form rocket companies to design and build a rocket while competing against other teams in an economic challenge. The team that comes up with the best benefit/cost...

The Mars Global Surveyor spent two years creating a mineral map of the planet Mars using thermal emission spectrometry. To help young astronomers understand this remote sensing instrument, have them simulate how data is collected and...

Students investigate the weather by reading children stories.  In this weather observation lesson, students read Cloudy With a Chance of Meatballs and several other stories about weather before they create a KWL chart....

Students examine the phases of the water cycle and water's different forms it can have. They work in groups to create pantomimes to illustrate the water cycle to their classmates.
