We had a bag of Oreos begging to be eaten, so we called our homeschooling neighbours over and decided to eat the phases of the moon
And we thought, "Why not make an edible comet?"
So we did.
Here's the nucleus: frozen juice and fruit cocktail
Then you freeze it
While it freezes you make craters on the moon, using flour and oranges or marbles
Then punch out the constellations
And make a constellation box to study the stars with
The comets still weren't frozen, so we read chapters of The Wonderclock and played with geoboards, legos and art stuff
Applying glo-in-the dark glue to our planet mobile.
Our friends leave and take their half-frozen comets with them
Working on our outer space puzzle
Finally frozen, we roll our nucleus in sugar to represent the coma part of the comet
A long fruit roll up makes for a good-tasting comet tail
