  Week 15:  1.) What did you learn this week? This week in the lab, we revisited the baking soda experiment. We were tasked with posing a question that students could answer through this activity. The question that our group posed was, “Is the weight of the baking soda and vinegar the same before and after they are mixed together?” The conclusion that our group determined is that the weights might not be exactly the same, but they will be very close before and after. First, we weighed the baking soda and vinegar in the Dixie Cups, then we mixed them into a plastic container that was sitting on a scale without screwing on the lid. Before we mixed them, the baking soda and vinegar weighed 12.8 grams. After, they weighed about 12.6 grams. We hypothesized that it weighed less after because of the chemicals escaping through the form as gas. Next, we repeated the same process but screwed the lid on after mixing the baking soda and vinegar. Before, they weighed about 21 grams. After ...

 Week 14:  1.) In the lab this week, first we used particle models to explain why a plunger sticks to the surface of a table. We said that the particles in the table are denser compared to other surfaces. When you push down on the plunger, the air inside compresses and pushes back against the pressure from outside. The density of the table also prevents air from escaping, which causes it to stick. Then our group had to make a flip video explaining why ice melts faster on a metal surface compared to wood. My group concluded that metal is denser. Because of this, heat travels through the metal particles quickly and has more collusions with the ice, which causes it to melt. More collisions will make the particles in the metal move faster, which causes an increase in temperature.  2.) I really enjoyed the flip book activity. I thought that it was very engaging compared to a generic worksheet. Additionally, I think it’s beneficial for the class to be able to watch the videos a...
