Science Night


I learned many things during this 3-day period of research for Science Night. For example, I have never heard of a guy named Eratosthenes before and this experience helped me to learn about him. He was a mathematician, geographer, and astronomer. Some of the things he did were he found a way of finding prime numbers and he adopted or created the word geography. I am very glad that I got to learn about Eratosthenes and what he did to make my life easier.

Science Lab


Yesterday in Science Lab I had a lot of fun. We learned about plastics and petroleum products and how much stuff they are in today. For example, I never really thought about flowers, light switches, paint, etc. with having either plastic or petroleum products in them. Also, Mrs. Martinez then told us a story about an experiment with a group of people who had the same blood type and then were separated into two groups and were fed for a week with the same exact foods except for lunch everyday group one would have homemade soup and group two had canned soup. At the end of this experiment group two who had the canned soup had 100 percent more plastic in their body than group one. Amazing right?

Science Lab


Today in Science Lab we had to clean a “bird” after an oil spill. Instead of using an actual bird, we used a bird’s feather. There were many choices of what we could use, like our group used pet shampoo, corn starch, and baby powder. After you put on the material, you would have to smell, look, and touch the feather to see if the product affected it. First we did the pet shampoo, it worked very well because the oil came off and the feather smelt very good. Next was the corn starch, it was absorbent and the feather looked and felt fine but it smelt terrible. Finally, my choice, the baby powder. Let me just say bad choice. I thought it would be a good choice because it is soft and is gentle. Apparently, it is a horrible choice to clean a bird’s feather. Our bird died because of my great baby powder. I would use what I learned today in the future if I would ever have to clean up animals after an oil spill. Science Lab was very fun and educational.
