Week 12

 Week 12

What did you learn this week?
This week we practiced skills like observing, investigating, and collecting data. We got to test objects and determine the weight of the object and if it sinks or floats. My group tested a cork, aluminum foil, a candle, chalk, and marble. 

What are new or remaining questions?
Why did the chalk bubble when it was in the water?
The small chalk took longer to sink in the water, why did that happen?

How can you apply what you've learned to your teaching in the future?
I liked how interactive and engaging this lab was and believe that it will benefit the student learning. Students learn better by being hands-on than talking to them mainly when working with young students. I can apply a lab like this in my classroom for upper elementary, 4th-6th grade. It allows students to have a bigger role in their education,

    Hi Olga! Great post. I think the answers for your question are that when chalk bubbles are placed in water, it is likely due to a chemical reaction between the chalk and the water. This reaction could release gases trapped within the chalk which causes the bubbles to form.
    The smaller chalk's longer sinking time could be attributed to its lower density than larger chalk pieces. The smaller size may also create more surface area, letting it float on the water's surface longer before eventually sinking.

    Elementary Science II Week: October 21th - October 25st  What did you do in lab this week? / What was the big question?  The two discussion topics for this week's lab is geologic time and earth viewer. We began by looking at a presidential elections are impacted by a 100 years old coastline. We learned that parts of the south were underwater as a point in history, flowing the blue line. Then as a class we got to place events on a number line ranging from humans appeared to moon was created. This allowed use to visual see how far away it took earth to become what it is now. It also helps break the misconception that after the big bang earth just appeared. Now that we have learned many things about our universe we answer the question on how to now placed them in order. If we put  all the formations of the Earth on a time line humans have only been part of the timeline for 2 million years.     Answer questions about the weekly text books readings...

   Elementary Science II Week 13: November 18th- November 22th What did you do in the lab this week/ What was the big question:  We started by talking in our groups about the two articles, Couple Inquiry and Sweater, and about how similar and different they are. Both talk about teachers letting go of the control. I think that is something a lot of us are not used to or have never seen. Even as a college student, I am used to being told what to do and study for. To then move to allowing students to take over the lesson can be hard. But both articles make a great point. The sweater article talked about how students naturally lead a lesson if and only need a little bit of guides. The Coupled Inquiry talked about allowing time for freedom but with guidance.  A fun fact that I learned is that Americans are lagging in academics and despise the free education we give. I find it interesting but also not shocking. In all my travels I have seen how smart students can be withou...

What did you do in lab this week? / What was the big question?  My group's big research question was about the earth's origin. There are so many misconceptions about how the Earth was made, for example, the Earth was formed instantly. Historically people used to believe that the Earth was the center of the world. We learned that current science understands that Earth is 4.65 billion years old thanks to geology and fossil studies we were able to set a date for the Earth.  We also got to hear from other groups about the origin of the Universe, the lifecycles of stars, galaxies, Black holes, and exploration of spa...
