Welcome to Science 6: Period 2!

What did we do during 6th grade in science? - Vicky Mai

Earthquake PBL

Our Earthquake PBL was about creating a stable house that is able to survive a strong earthquake. The driving question to this PBL was, "How can we, as structural engineers, construct a two story house in California for Tony Stark that withstands seismic activity?" Our team design for Tony Stark is (for the main material of the house, we have Popsicle sticks) wood for the four walls. For reinforcement, we have (cut-in-half) straws in the back. The second floor are toothpicks. For more reinforcement, we have straws on the side connecting with clay. We really focused on reinforcement more than design. But we added a "balcony" if we had enough material(s). The main points I learned during this project was to learn how to be prepared for an earthquake, to learn about earthquakes, to learn how to be cooperative and work in a team, and learn how to be creative and use your resources wisely (while building).

30 Hands Project

From doing this project, I learned information about climate change, the Greenhouse Effect, and global warming. I learned about how global climate change is effecting Earth and the environment. Climate change is the shift in long-term, global weather patterns due to human action. The Greenhouse Effect is the process by which heat is trapped in the atmosphere that "blanket" around the Earth. Finally, global warming is one type of climate change, and it refers to the increasing temperature of the surface of Earth. During this project, the part I enjoyed the most was creating the PicCollages. It was fun because you got to customize your own slide and make it how you want to. (ex. down below)

Invention Convention (with Haley Kang)

Our environmental problem solves water pollution. We’re going to place our invention (The Solar Rod 5000) in polluted bodies of water (worldwide) such as Matanza-Riachulo river in Argentina, the Citarum River in Indonesia, and much more (hubpages.com). It picks up trash or recyclables, and we have another building that sorts these two. Our invention collects trash in the ocean and recycles as well. Our invention is a rod that is on a float. This rod has solar panels on it, so the sun can transfer energy through the rod. (This rod is controlled by another building.) This energy then activates the robot arms that is attached to the rod. The rod has a camera on top of it, so the building can control/move/look out for danger for the rod (ex. if there's danger, like powerful currents, then the building sends it back). The workers in the building move the robot arms and the rod to collect all trash or recyclables in the water. When the robot arms grab the trash, it transfers that trash to the container that is connected to the rod. The container has a rim, and when the trash reaches the rim, the building sends the rod back. There, the workers separate the trash from recyclables. After they are separated, we send the rod back to the water and start the cycle again.

Extra Credit - Erosion, Deposition, and Weathering

My favorite unit this year was learning about erosion, deposition, and weathering. I liked this unit because I think it's so amazing to learn about how Earth or other land forms. We learned that erosion is the process in which water, ice wind, or water moves weathered rock or soil. It forms lands, like valleys or mountains. Deposition is the process in which sediment is laid down in new locations. Weathering is the process that breaks down rock and other substances at Earth's surface. There's two types of weathering - mechanical and chemical. Mechanical weathering is when big rocks are physically broken down to tiny, smaller pieces of rock. Chemical weathering is the process that breaks down rock in chemical changes, My favorite lab we did with this unit was the stream table demo. We had a stream bed (large or narrow) and we tested/observed reasons for sediment loses.
