Volume and Density

This week was a week full of metric units in science,  in fact in Mrs.G's classroom, inches and feet are outlawed. This week involved dunking willing humans(Ellie, Kyler, and Jane) into water to find their volume.

To start out the week we learned precision and accuracy by throwing a tennis ball at some one with an apple on their head with a target behind them. I learned that an example of accuracy would be throwing a dart in the center of the target. Precision would be if you threw six darts in the same spot. Mrs.G showed us this is a much more fun and exciting way like everything else this week.

We started on our volume and density lab to help us understand a bit more how to calculate volume and density in regular and irregular shaped objects like humans. I was absent on Wednesday so I apparently missed a baby squirrel named Hootie which I was super bummed to have missed because everyone said it was super cute and small. The one thing I'm so glad I didn't miss is Ellie being dunked. By dunking her in water we learned her volume from how much water she displaced. This helped me learn in the future if I ever wanted to dunk someone for fun I could say it was for science and I wanted to figure out their volume.

On Thursday even before dunking Ellie we layered different liquids depending on how dense they were. Some liquids were honey, soap, oil, and water. I learned that when all put together the liquids would separate because of the difference in density.On Friday we had our quiz. I think I can improve on using all my studying resources like the assessment in the textbook. I think I did pretty well on the quiz  but there is always room for improvement. Overall I think this week was really fun and can't wait to see what next week has in store.
