Discovery Lab at Central Washington UniversityBy discoverylab | October 4, 2016 | Uncategorized
On Friday we spent the day on the Central Washington University Campus. We are so lucky to have so many families with amazing community connections. We have four CWU faculty families. This time we were hosted by Allyson in the Science Department.
We started our day in the greenhouse. Our guide explained how scientists use observations to create new questions. It was a lovely experience to have the students observations guide our tour. Students noticed that there were plants with enormous leaves, and we discussed why it would be useful to have such a big leaf in the canopy. We saw how a bromeliad can hold water for the inhabitants of the jungle and how plants defend themselves.
When we went into the cactus house, we learned that thorns, and milky sap and a chemical that would make you feel full if ingested were ways a cactus could defend itself. We even saw something the cactus might need to protect itself from, a giant tortoise!
Our next stop was the lab. Allyson led us through an experiment using candy. We first learned about a problem, which was a friend at “Camp Way Too Hot” needing an emergency candy delivery. Then students choose two candies to test. Using hot water, they submerged candies for two minutes then recorded their results.
Each group then shared their result in a scientist meeting. After finding licorice and Swedish Fish to be the most solid, they went back to the lab with hotter water to see if they would really stand the heat. After yet another meeting, we concluded that licorice was the most heat resistant.
Allyson will be helping us all year to learn about matter. What a treat to spend the day as scientists.
