Why Angle Changes Intensity

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these simple...

When exploring Mars, spacecrafts are exposed to 5-11 times more sunlight than when near Earth. Groups of pupils complete a hands-on activity to explore how distance and angle of the sun affect temperature. Through discussions, they then...

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...

If you have solar car kits for your junior high schoolers, they can experiment with photovoltaic cell angle, light intensity, and aerodynamic design to discover what makes their car move more quickly. This is a classic activity to use...

Students examine the difference between magnitude and intensity in earthquakes. They complete map work and write a first hand account of a person living in each level of intensity on the Modified Mercalli Scale.

Students study about the changes of puberty for boys and girls. In this health lesson, students study how the body changes during puberty and make a presentation about a significant change that can take place during puberty and how to...

The North Star changes — it was previously Thuban but now is Polaris, and in the future, it will be Vega. The video discusses the cycles observed in the sky with only your eyes. It focuses on the zodiac constellations and why they are...

There are few natural phenomena as startling as an earthquake, and depending on the building you're in, these experiences can be downright terrifying. Follow along as this video explores the factors that determine how a building reacts...

Learners explore environmental care by researching the impact of human beings on our planet. In this climate change lesson, students utilize the Internet to read informational text about climate change and the effect it will have on our...
