Astronomy projects

To conclude our 4 weeks of studying Mercury, we made our first ever salt dough model - Do you like all the craters?


This past week, we began our study of Venus.  Venus is "HOT, HOT, HOT!" and has many volcanoes on its surface.  Using butter, flour, and a small dish, the children saw how rock (butter) is hard when it is cold, but when heated, becomes a liquid.  When it erupts out of a volcano, the melted rock (lava) spills down the side making streams.  Then, after a while, it hardens again into rock. 

(I took these pictures to put in our Astronomy Notebook Journal and just decided to share them here, as well.)
