STEM Activity 7: "Solar System Scale"

solar system modeling tapestudents creating a scale model of the solar system Purpose: Children measure solar system object distances using astronomical units (AU) and learn how long it takes sunlight to reach each planet/object.

Supplies needed: Unobstructed space approximately 6’ X 60’. We provide the measuring tape and planet/object cards.

Age level: upper elementary school. For groups of 8-30.

Notes: One child is the Sun and other children hold a card representing a planet/object. Since children are disappointed if they do not have a card to hold, additional moon and asteroid cards were added. Math lesson on ratios for upper elementary or above.
