Mercury
Ages 7–10 · 7 minutes · Science
Bring your sunglasses! Start learning with the innermost planet, Mercury.
Students start their exploration of the solar system with the innermost planet, Mercury. Students learn many fun facts and are asked to make connections, such as:
- why Mercury is so hot
- why Mercury orbits the sun faster than the Earth and has a shorter year
- how the surface conditions on Mercury are not conducive to life as we know it

- ESS1.B — Earth and the Solar System: The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them. This model of the solar system can explain eclipses of the sun and the moon. Earth’s spin axis is fixed in direction over the short-term but tilted relative to its orbit around the sun. The seasons are a result of that tilt and are caused by the differential intensity of sunlight on different areas of Earth across the year. The solar system appears to have formed from a disk of dust and gas, drawn together by gravity.
