After we helped Saturn return it's rings to their normal size, we played Moon Rock Relay. I found some foam balls at the Dollar store and ripped them up into rock size pieces (it was harder than it sounds!). Then, I got four buckets, split the kids up into four teams and they were supposed to, one at a time, pick up a moon rock and place it in their team's bucket. Whatever team had the most moon rocks in their bucket once all the "rocks" were gone, won!The only thing left for our astronauts to do was discover the moon. I made this moon cake by putting half the batter in an 8" round pan and the other half in a glass oven-safe bowl. It stacked perfectly!
To make the inside more fun I did rainbow cake batter. It didn't turn out exactly how I wanted since I bought a yellow cake instead of a white. I'll know better next time!
