This was a great week full of hard work and fun experiences!
Kids were working very hard as evidenced by the following images. They were not staged! :-)
We learned about the work of Dr. Goldberber towards finding a cure for a terrible disease called Pellagra. (Ask your child for details.) This highlighted how he studied people scientifically.
We then all received virtual headaches (by drinking different mixes of lemonade) and then some of us were cured while others received a placebo! Here is a VERY sloppy graph of the class data which clearly shows that the medicine worked while the placebo had an odd "placebo effect" on the some of the students!
Next we did our touch sensor experiment. See the movie above to see some of the students on action. This tested the sensitivity of our sensory neurons! The data clearly showed that when the toothpick were .7 cm apart they were hard to detect as two and often felt like one toothpick! We learned that the one toothpick trials were a control to help us compare our data.
Beaker was very proud of you all this week!
Mr. F :-)
I love science sooo much this year. Last year, we did boring experiments and analysis questions were a dread, but now it seems more fun somehow. I loved the week and all we did.

Thanks beaker

I think science class will always be a mix of activities/labs and analysis of our learning. I wish it could always be only activities but then we wouldn't deepen our understanding of the material.
ReplyDeleteI'm glad you like it so far! I hope it stays that way.

I enjoyed all of the experiments last week! They were all soooo much fun, and interesting too. The pellagra video was kind of sad for me, but it was very informational. I love science this year!
