Today we summarized Activity 21, and defined the Law of Superposition. If you were absent, you need to find out how geologists know the age of a sediment layer, and what information they are able to gather based on the layer's thickness and composition. I also checked analysis questions and graph from Act. 21 and put it in the grade book for 3.25 points. We then moved on to Act. 22 "Rock Cycle Game" where we learned how rocks undergo change over time. Students played the game, and then answered analysis questions 1-7. This is homework if you did not finish. FORWARNING!!!! We will be taking the Unit Test for Rocks and Minerals around the time Science Fair projects are due the week of March 12. Please begin to prepare and plan accordingly.

Today students learned about scientific models and sedimentary rocks. We used different color tokens to model out sediments layer on top of one another over time. Students collected group data and then collaborated to create a class set of data. We then made a graph from this data. Homework is Analysis Questions 1-5 from Act. 21. Also, I forgot to attach the mineral video from last Friday, so I have attached it below for any that have missed it. You will need to take notes on it in order to take last week's notebook quiz. ![]()

Today in class we examined different rock samples in Activity 20 and made observations. Based on these observations, we were able to conclude the category each rock belonged to: metamorphic, igneous, or igneous. Students filled out student sheet 20.1, and Act. 20 Analysis Questions 1-2 are homework. ![]()
Today in class we completed Activity 19 "Rock Formation." Students teamed up and split the reading among the group. Unfortunately if you were absent you will need to do all the reading by yourself. I have attached the worksheets students filled out. Homework is to finish AQ 1-4, which is on the attached sheet. ![]()

Today we completed Activity 18 "Every Rock Tells a Story." Students also did analysis questions 1-4. This is homework if not finished in class. Students then set up their lab notebooks for Act. 19 and completed a warm up. If you missed last Friday, we had a quiz. Please take notes on the video below and come in to make up the quiz. Also, Science Fair help session is tomorrow. Please come to the library from 8:15 to 9 for assistance! ![]()

Today we started class by watching a video of the 5 characteristics of a mineral. Students took notes on this video, and then took a lab notebook quiz. There is no homework.
Today students investigated how to identify unknown minerals in rocks. We did this in Activity 17 "The Minerals in a Rock." Homework is Act 17 AQ 1-4. ![]()
Today we did a lab that was not in the textbook curriculum. We examined 4 unknown minerals and used different objects such as iron nails, pennies, etc to test the hardness of each mineral on the Mohs Hardness Scale. Students use this information to identify the minerals. There is no homework
Today students completed Activity 16 tested properties of two unknown minerals and used these properties to identify the minerals. Students then did Act. 16 AQ 1-3. #3 went into the grade book (This is homework.) ![]()
Today we had shortened periods for a Unity Assembly. We set our lab notebooks up for Activity 16, and then used the rest of the class time to go over the Weather and Atmosphere Test. There is no homework. Please remember that there is no school next Monday, and that we have Science Fair help next Tuesday in the library from 8:15 to 9:00.
