I got less science fun packed into the summer than I had planned, but I also didn't get my gallery wall started. The summer was busier than expected. That said, the boys and I did do a few experiments.
We had fun with learning about the different rock types thanks to Pinterest. It was much better than our Pinterest Fail in the spring.
|Tad excited about science. Warms my heart.|
|Our ingredients. You're supposed to use Starburst candies. I used Starburst and Laffy Taffy candies because that's what I had in my cabinet (thanks to Easter. Okay, let's be honest, some of those might be from Halloween. No judgement.)|
First we made sedimentary rocks. Pressure had to be applied to our rock layers.
|A toy box didn't work.|
|Hmmm, what could cause enough pressure to smash our layers together?|
|Sitting on the candy didn't work either.|
|Sitting on a chair on top of the candy worked!|
They smashed their rock layers with siting in a chair on top of the rocks, and then the rocks got heated in the oven.
|The candy is supposed to be wrapped in wax paper then foil. I had no wax paper so this happened. Oh well. The boys got the point.|
Finally, the boys made igneous rocks - heat only.
We also looked at pictures of the different rocks in one of my earth science textbooks along with talking about the connection to volcanoes. Fun times.
|Those aren't H's, they are I's. For Igneous. M for metamorphic. S for sedimentary.|
I took the boys up to the Earth Science lab at school so we could make volcanoes. This is by far their favorite activity.
|Bear and Yellow Friend came along as well.|
|The boys were super excited. Can you tell?|
|Ah, the old baking soda and vinegar trick.|
|The boys also experimented with whether or not the thickness of their lava will make a difference in the explosion.|
|Their findings suggest that the thickness of the lava does not affect the reaction between the vinegar and baking soda.|
