Lab Week 14

 Today in lab we started by creating definitions for matter, properties, and particles. Then, we tried to explain the motion of particles when a plunger sticks to the table. We thought that as you put pressure on the plunger, it pushes the air particles out through the bottom. Once you stop putting pressure the seal forms because it is not being pushed up by the pressure of the air. The seal is what prevents air from rushing back in and putting air particles in between the plunger and the table, so it stays sealed to the table. 

Then we tried to design explanations for why ice melts faster on metal than wood, and why water condenses on the outside of a cold can. We created a flip book for these and showed the steps of each with explanations. 

One thing that is clear about this is the movement of the air out of the base of the plunger when we press down, but something that is less clear that we are investigating is why the plunger gets stuck to the table. 

One question I have is what causes metal and wood to have the different conductivity? I can see that they do, but what about the objects makes those levels of conductivity different?

    Hi Brenna, I also was wondering why the conductivity is different in these two materials. I think that the things we did in class were a great way to try to understand particles.

    Hi Brenna! I think the wood and metal have different conductivity because they are made of different substances, and metal is more conductive than wood.

    Hi Brenna! It can be confusing to understand why the metal and wood have different levels of conductivity. But, it is important to remember that it is because they are made out of different substances that have different properties.

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...
