Today in integrated science, students prepared and debated the answers to the Free Body Diagram Worksheet. Tomorrow, we’ll be starting a lab that covers Newton’s 2nd Law of motion.
Science 8 students today began the Depositional Environments Lab (Depositional Environments Lab Stations). The purpose of this lab is to teach students how to use evidence in the geologic record to interpret past conditions. Students began with a short video about the Cargill Salt Mine, and then they were asked to make a claim about the past environment for that area. Cleveland (and most of Ohio) used to be under an ocean. The salt layer was evidence for this claim because salt is created when ocean water evaporates, depositing the salt in layers at the bottom. This lab helps give students some information about common or important features to be aware of when interpreting rocks to determine past environments. We’ll be continuing this next week.
Today in class, integrated students began to whiteboard and share their results from the Free Body Diagram Worksheet. This activity will extend to tomorrow as well.
Science 8 students worked on the Geologic Features and What they tell us Worksheet to learn how pieces of geologic evidence can be used to determine the past environment. Students will use the Relative Dating Practice homework tomorrow and practice creating the stories that go along with the problems.
Today in class, students in Integrated science reviewed their quiz over force basics (Newton’s 1st and 2nd laws, qualitatively). Students then worked on taking notes and learning about a new tool to describe the forces on an object with the Force Diagram Notes. The point of making force diagrams is to learn about motion, and not to learn what forces are acting on objects. We will be continuing the notes tomorrow, and then learning how the objects will move based on the forces acting upon them.
Science 8 students finished up the Making North America-Origins video worksheet, and grading the quotes section. The remainder of the period was spent reviewing the quiz from last week over seismic waves and Earth’s interior (Seismic Waves and Earth’s interior Quiz KEY). There will be a retake of the last question/exit ticket tomorrow, as well as new information on depositional environments.
Science 8= Do 5 points of annotations on the article “Everything Worth knowing about: Scientific Dating Methods“. Due Friday. Quiz Retake Friday.
Students in integrated science received their tests from the motion unit back today and reviewed the information on them. We discussed the scoring and final grades before moving on to the topic of force. Students took a few brief notes on force and then began work on determining motion direction from a few simple pictures of objects being pushed or pulled (Force Diagrams). Students will need to begin their annotations for the Sir Isaac Newton biography (Hero’s journey Socratic Friday).
Science 8 students today finished up the obscertainer labs, and we’ve never seen so many students curious to determine what’s inside a plastic disc before! Students were able to reflect on why we did the lab. Part of the purpose was to see how indirect observations can help us infer the properties of something. More specifically, it helped us as an analogy for how we use seismic waves to determine the earth’s interior structure. Students then took the Earth’s model notes and then discussed/reflected on the patterns in the evidence we have closer to earth’s surface and closer to the center of the earth. Students will learn more about seismic waves tomorrow and how they tell us about Earth’s Interior. For Friday, students also need to do their annotations for the articles “Weather Bomb” storms send tremors through Earth and Tracking warfare by “earth shakes” .
Homework: Integrated= Annotations for Sir Isaac Newton biography (Hero’s journey Socratic Friday); Quiz Monday on Forces
Science 8= Annotations for “Weather Bomb” storms send tremors through Earth and Tracking warfare by “earth shakes” due Friday. Quiz Monday on Seismic Waves.

Today in integrated science, students worked on finishing up the motion detector activity from last week. Students were able to test their motions to create the graphs that they intended to, but they soon found that Mr. Ross is master of all motion detector walk-outs. Students then continued with the question of why do objects move? Students were finalizing their potential answers but will continue working tomorrow.
Science 8 students began class today by making a new section for Earth’s Interior in their notebooks and estimating the proportions of different layers of Earth. Students were then given the actual sizes, and they were floored when they discovered how small the crust is. Students wrote some “Aha moments” for how the size of the crust explains the ease with which magma/lava can penetrate it, and also how easy it is for convection currents to move the crust. We asked students to determine how they thought scientists had figured out the sizes, and then we looked up how far humans have drilled into the crust. At only 12.26 km, the deepest well was not even half way through the crust. Students began the obscertainer activity to help them learn about indirect evidence, which we’ll discuss tomorrow.
