Lab Week 13

Today we started class by sharing our modifications we made to the 5E lesson plan from last week. Then, we started developing models as a group to show different densities of substances. We discussed what this means and what it might look like, as well as how this conversation could look among elementary students. Then, we talked about our last investigations that used the M&Ms and tried to explain why the colors spread out in the water using models. This led into another investigation on if certain colors spread out quicker than others using different variables. We used salt in room temperature water. 

One question I had was why the control group's colors spread out more evenly than ours, which spread into trail-like shapes and not out around the whole thing.

We can use this in our future classrooms as a part of engage or explore part of a lesson plan, because I think that students would engage in valuable conversation about why certain variables (water temp, sugar, salt) change how the colors spread out in the water. It would be a good investigation for students to ask questions and learn about properties.

    Hi Brenna, I had the same question as you with the control groups colors spreading out. I wish we could have seen all of them at the same time to really compare the differences.

    Hi Brenna! I think that this activity would also be great to do in our future elementary classrooms. It is very engaging and gets the students to start asking questions.

    Hi Brenna, I liked this activity but I wonder what would have happened if you used hot water with salt?I think allowing students to explore these different combinations would be a great way for them to explore this topic.

    Hey Meredith, I also was wondering why the control group's colors were more evenly spread out.
    Very good question, hopefully we will learn more!

Methods II: Week 9

 What did we do in lab this week? This week we focused a lot on the timeline of our existence and Earth's existence. We looked into big events such as the formation of the earth, water found on the earth, Earth freezing over, the first plants and animals on the earth, and when humans first existed on Earth. We emphasized that humans have been here for a very short time in comparison to the timeline of the universe since the "Big Bang". We used a simulation called Earthviewer to look through some of the big events and eras our earth has gone through.  What was the big question? When did big events relating to our Earth take place? What did we learn in Thursday's discussion? We took our Space exam so we did not continue our discussion on this topic.  This week's reading:  Chapter 15: History of Earth - I learned: the Earth was able to freeze over completely due to a positive feedback loop. When Ice accumulated on the planet, it reflected more and more light away fro...

Methods II: Week 11

What did we do in lab this week? We started by talking about the law of superposition, that the rocks further down in the earth are older than the ones above it. We also talked about how rocks are changed, through weathering/erosion (chemical or physical). We looked at different samples of sand and tried to determine if it was eroded by water, wind, or glaciers.  What was the big question? The big question was, how is sand made/what do different kinds of erosion cause?  What did we learn in Thursday's discussion? In our lecture, we did some investigations about what would float or sink in water and read a book about Archimedes' rule. We talked about how we could determine if the two objects were the same, using water displacement and buoyancy. Then we used this method to figure out how we can determine how many crystals/empty space are in a geode. We can decide how hollow a geode is using Specific Gravity. If it is less than 2.7, then it is at least somewhat hollow. If it is 2...

Methods II: Week 8

What did we do in lab this week? This week in lab, we focused on presenting our group slides covering several different ideas. We were able to practice teaching about these topics rather than just sitting and listening and learning ourselves. Being able to teach our classmates helped us to practice some of the tactics we have been seeing and learning about, as well as address misconceptions about each topic which we have learned how prevalent they are even in higher education.  What was the big question? The main themes we covered in our presentations were, the origin of the universe, lifecycles of stars, galaxies, black holes, origin of the earth, and space exploration in the past/present/future.  What did we learn in Thursday's discussion? We started by doing a short review about the moon phases and space. Then we discussed the Big Bang Theory as well as alternative theories. Then we went through the life cycles of stars and how/why stars are different and change. Next we ta...
