Any great suggestions for inquiry based labs in Physical Science that are more challenging for third grade?

Hello! I found a really interesting lab for teaching weathering versus eroding that could definitely be inquiry. You would need to pre-make some 'mountains' using rocks, dirt, and gelatin in order to do this experiment. You essentially create two separate 'mountains', one out of rocks and gelatin and one out of dirt and gelatin. The students can create hypothesis for what they think will happen when you pour hot water on each 'mountain' and then record what actually happened after the hot water is poured (rocks stay in place but there are gaps now-weathering and the dirt mountain got smaller as dirt was moved away-erosion). You could have them draw before and after pictures, or the students could try to guess which mountain will represent weathering and which one will represent erosion. I am including a link to the site I found it on, but make it your own!
