Standard

• 6.ESS.2 Design models to describe how Earth's rotation, revolution, tilt, and interaction with the sun and moon cause seasons, tides, changes in daylight hours, eclipses, and phases of the moon. 

Collision!

• About 4 Billion years ago a Mars sized planet collided with Earth, tilting it on it's axis.

• This caused the tilt that is responsible for our seasons.

• This is the longest day of the year.

Summer

• During summer the hemisphere is tilting toward the sun

• It is getting very direct light

• The sun is high in the sky
