Report Cards Have Arrived!

Your child's report card was sent this week and most students received theirs on Thursday. If you have not received one by Saturday, please contact the office to let them know. You can also use your Pinnacle log in information for your student to check what their report card was too.



This week, we have done some review of cells and begun some inquiry into stem cells. The students have lots of questions, but have gathered lots of knowledge. Please talk with your child about what they have learned in class, it will really help their understanding. We are also closing the week with Cell Division, but going more in depth next week. This is a big topic for students that they need for high school.



On Thursday next week, we will be having a midterm, but on the Science Binder. I have been telling the students since Wednesday about this so that they get their Binder in order and are acquainted with it.



Also, students received new planners yesterday and they should be using them in each class.



Next Friday is a District Professional Development day so there is no school for students (2/6/09).



Have a great weekend!

Brrrr!

It has certainly been a cold week, cold enough that we had today off from school. How do the people in Minnesota and the Dakota's do it? Well, since we missed school today and Science Binders and late work were due today, we will be collecting all this on Monday. Hopefully that will give some students some extra time this weekend at home to get caught up.

This week, we are going to be looking at global warming and its connection to the car industry and then doing some research on biofuels for vehicles. What is the current research and how does Detroit need to react to this information? Students will be creating an advertisement on a biofuel that they have been assigned to research with a partner. While they are working on this, I will be interviewing students, one-on-one, to assess their knowledge of gasoline production, the internal combustion engine, global warming and their knowledge of their biofuel.

Students have all of Friday off. It is teacher records day.

Have a great weekend and stay warm!

Here's the schedule:
Science
Monday, January 19
Objectives:
At the completion of this activity, participants should be able to... write a definition of global warming.

Happy New Year!

I hope everyone has had a good Winter Break with an extra day added in there :). Before Break, we finished our Unit on the Advanced Rock Cycle and took the assessment on Thursday, December 18th. There was an assembly that ran longer than expected that day so 7th hour has 30 more minutes to finish their assessment on Monday, January 5th. If your child missed the assessment, please remind your child to take care of getting it finished after school at Homework Hub on Tuesday. I would like to be able to hand the assessment back to students quickly so I need all students to take the assessment quickly.

We will be beginning 2009 with a new WMU intern, Ms. Tracie Cagle. She came in and observed for two days before break started so most students have met her. Welcome to Milwood, Ms. Cagle!

If you did not know, we have been holding Homework Hub after school during the last two weeks of school. All the team teachers rotate through doing this and the schedule is posted in the team hallway each week. Students must sign in and also get a ditto slip that they fill out what they did and if it is finished or not. Then the teacher initials it and hands one sheet back to the student so they can show the parent/guardian and the teacher files the rest of the copies. Lots of kids have been taking advantage of this program either to just get their work done or get help.

We are now beginning our unit on Biofuels. What an opportune time to look at biofuels and how they affect Michigan and Detroit's Big Three! If you run across any information on the changes that Detroit's automakers are making to vehicles in order to improve sales please forward it to our classroom for discussion. Thanks.

Here's the schedule:

Monday, January 5
Science
Today, we will be getting our Science Binders in order so they are ready to turn in within the next two weeks for a final grade. We will also be beginning to see how the Biofuel unit looks and completing our Mind Map. In Science class, we are also responsible for reviewing hallway behaviors for the new year.

Tuesday, January 6
Science
Hopefully all assessments will be finished so that we can pass them back, look over them and then complete our test reflection and earning 1/2 points back.

Science Connections
We will be continuing the article on "Petroleum" that we began on Wednesday before break. (See December 17th and 19th).

Wednesday, January 7
Science
We will begin class with a reading strategy called, "BKWLQ". We will have a short article on what is occurring in MI currently with the automobile industry. Then we will create a list of things we already know about the situation with a partner at our table using the Kagan Strategy "Rally Table". Then we will share our ideas as a class using the team/student selector. After sharing, we will then go back to "Rally Table" to brainstorm all the things we want to learn about the topic during this unit. Again we will use the team/student selector to pick people to share their ideas for the class list. We will then read an article on the plight of the auto industry in Michigan independently and Rally Robin at our table ideas from the article. Students will complete an Exit Slip to leave class.

Thursday, January 8
Science
We will begin learning the vocabulary that will help us with this unit of study by completing Word Boxes. If they are completed in class today, students may turn them in, but they are due by tomorrow. Here are the words: biofuels, carbon dioxide, combustion, crude oil, emissions, global warming, hybrid, hydrogen, innovative, nonrenewable, oil refining, petroleum, renewable, and sustainable.

Friday, January 9

Science
We will begin our study of biofuels with a study of what the production of gasoline entails. Students will be given a primer, "How Gasoline is Made". We will work in pairs to read portions of the text and then come back together to take our Lancer Notes. This activity will be finished during Monday's lesson and there will be questions assigned to students to turn in on Tuesday, January 13th.
