Week 7: Rocks and the Rock Cycle

1. What did you do in lab today? In the lab, we talked about different grades and what a certain grade actually means. We also went over test questions and the different percentages of what people got right and what people got wrong. We also learned about different types of rocks, and we made them out of starbursts and melted them into the different kinds. 





 2. What was the big question? What causes rocks to transform and form different types of rocks?
3. What did you learn in Thursday’s discussion? We learned about the rock cycle. I also learned that fossils are usually found in sedimentary rocks because they form in layers over time. I also learned about buoyancy objects like Coke sinks because its denser than water, while diet drinks float because they have less sugar and more air. Lastly, I learned that Archimedes’ principle helps us find the specific gravity of objects by comparing their weight in air and water. Using this, we can tell if a geode is hollow or solid.
1. What did you learn? I learned that rocks come in three types. These include igneous, sedimentary, and metamorphic. The rock cycle shows how these rocks can change from one type to another through processes like heat, pressure, and erosion. I also learned how geodes form with crystals inside and how Archimedes’ Principle helps us tell if a geode is hollow or solid.
2. What was most helpful? The most helpful part was learning about the rock cycle because it showed how rocks change over time and connect to each other. Also, understanding Archimedes’ Principle helped me see how scientists figure out if a geode is hollow or solid, which made the lesson more interesting and practical.
3. What do you need more information on? I want to understand better how heat and pressure change rocks into metamorphic rocks.
5. What questions, concerns, and/or comments do you have? Nothing right now

Week 10

Image
  What did you learn this week?  This week, we learned about evolution and its four main drivers: natural selection, genetic drift, migration, and mutation. Natural selection is the only one that isn’t random because it helps organisms survive. We did a preying on beans activity to see how natural selection works. We also visited the School of the Wild and acted as students in their lessons. In the lab, we talked about mutations and genetic drift, which is when allele frequencies change randomly. Migration can change the biodiversity in populations over time. We also learned how adaptation relates to natural selection. Are you able to relate what you learned to what you already knew? Yes, I can relate what I learned to what I already knew. I knew natural selection was important, but I learned it’s the only driver that’s not random. I also knew about mutations, but now I understand how they can affect evolution, especially with genetic drift, which is random. Migration makes se...

Week 3: Space: The Moon

Image
What did you do in the lab today?  In lab, we learned about how the Moon looks different in different places and why some parts of it are darker. We did an experiment using flour and cocoa powder to model the Moon’s surface. We dropped different-sized marbles from different heights to see how craters form and why there are darker spots. When the marbles hit, the darker cocoa powder showed through, just like how real impacts on the Moon can make some areas look darker. We also talked about how the Earth rotates counterclockwise on its axis, and we learned the difference between rotate and revolve . Rotate means spinning on its own axis, and revolve means moving around something else. Then we used styrofoam balls and a globe to figure out where the Moon would be during its different phases, like new moon, quarter moon, and full moon . We also learned that the Moon has a front side, which is the side we always see  , and a back side, which is the far side we never see ...

Week 10: Layers of Earth, Convection Cells, and Plate Tectonics

Image
  What did you do in lab today?  In our lab, we talked about the layers of the Earth, such as the crust, mantle, and core, and learned that the iron core helps protect us from the sun’s radiation. We learned about convection cells and how heat and density make the Earth’s plates move, which can cause earthquakes and volcanoes. We shared our convection cell videos and talked about how convection is like what happens in ovens and ocean currents. We also talked about why earthquakes and volcanoes can happen away from plate boundaries. For our lab activity, we used graham crackers, rice cakes, and whipped cream to model the three types of plate boundaries: divergent, convergent, and transform. What was the big question?  What is the Theory of Plate Tectonics​ What did you learn in Thursday’s discussion? I learned that earthquakes, volcanoes, and mountains all happen because Earth’s plates move. Earthquakes are caused by pressure building up and then breaking. Big ones can be...
