Fifth Week

It's been so easy to learn more in chemistry the past week since it has been so fun. I stay active, and am able to easily pay attention instead of drifting off and daydreaming all hour. We continued working with density and applying what we've learned to different scenarios. In the beginning of the week, we planned a lab in which we would find the density of two students. We decided to use a 44 gallon trash can to fill water with, and then use the water displacement technique to be able find the volume of the student once they got in the can! However, the displaced water would not stay in the can, of course, so we put the can in the middle of a plastic baby pool. This pool would capture all of the water that flows out of the trash can. After the water was displaced, we would gather the water from the pool into 2 liter bottles, using small cups to scoop up the water and put in the bottle. By doing this, we could find the volume of each student. However, with one of our students the water rushed out too quickly and much was lost onto the lab floor, so we did not gather all of the water that was displaced and therefore got a lessened reading of the student's volume. The students that were used also weighed themselves the night before the lab, so that we could then convert their weighting pounds to grams. Also, we could convert their volume from liters to milliliters, and then find their density in mL/g. We found that our male student was denser than out female one, but he also weighed almost 60 pounds more. As the lab was going on, we had people taking videos, pictures, and working on a presentation of the data in a PowerPoint. It successfully displayed our data and results with plenty of pictures and videos. The next day we finished the PowerPoint on google drive, so that everyone could make edits and input data which was a very convenient thing to have. Friday we took our Unit 1 Assessment. I feel confident in it since I knew the standards well and felt very prepared. Like I said, learning is a lot more easy when it's fun and keeps you involved in an active discussion.
