My Angle on Cooling—Effect of Distance and Inclination

For Teachers 5th - 8th Standards
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...
