Most buildings have leaky places where air can enter or escape — around windows, ceiling openings like pipes, wires or chimneys, and construction joints such as where the wall meets…
In this activity, you will use a temperature sensor to relate changes in sunlight to the temperature of the air trapped in a container.
Heat flows through solids at rates measured by their conductivity. The rate of heat flow is also proportional to the thickness of the material. This model compares the rate of…
The rate of heat flow between two objects is proportional to their difference in temperature. One experiences this every day, with stoves, outdoor weather and touching things. If you touch…
Learn to connect position-time and velocity-time graphs. Explore velocity using an animated car icon connected to either a position-time or a velocity-time graph, or both. Then investigate other motion graphs….
…Students can alter the environment by “growing” a chain of mountains through the field. Students are challenged to grow the mountains to their maximum height (corresponding to the maximum change…
Investigate the effect of gravity on objects of various mass during free fall. Predict what the position-time and velocity-time graphs will look like. Compare graphs for light and heavy objects….
Use a series of interactive models and games to explore electrostatics. Learn about the effects positive and negative charges have on one another, and investigate these effects further through games….
How does solar radiation interact with the Earth and its atmosphere to cause global warming? Use this model to see what’s going on at the molecular level. Watch the effects…
People like to avoid large temperature swings in buildings because it’s more comfortable. The heat capacity of the building is useful in reducing swings, especially in solar houses where the…
