Summary: This week we learned about fossils and about different layers of rocks. There are also different types of fossils. Some types are when an insect get stuck in sap and their body is preserved or when a plant or shell is stamped onto mud and the mud hardens creating the shape. Another is when a dinosaur died and it gets buried until a couple years later when a geologist digs it up. There are also different terms being used to describe certain rock layers. Some of which include relative age, absolute age, extrusion, intrusion, and more. Relative age is when you compare an age of something to another thing. An example is " she's older than him by 1 year" the example is comparing someone's age to another's. For absolute age it shows the exact age for something or someone. An example is "this car is 5 years old" or "my dog is 4 years old". These examples show the age is the car and the age of the dog. Then extrusion is when magma cools on the surface and it's younger than the rock underneath it. Lastly intrusion is when magma cools underground and the rock is younger than the rock surrounding it.
SP7: Engaging in argument from evidence
In science, reasoning and argument are essential for clarifying strengths and weaknesses of a line of evidence and for identifying the best explanation for a natural phenomenon.
Did you participate in a class discussion providing evidence for your answers, and/or used the ACE strategy in your work?
Yes we discussed different types of rock with each other. We took notes and when a question was on the presentation the teacher asked us to discuss with our table. We also did a worksheet about a certain type of fossil that appeared in one place and in another. We discussed this and people provided evidence from the paragraph when we went over the answers.
