Can't they all just get along? (referring to atoms, of course)

Life Science
Those students with time-intensive projects should start their experiments by this coming weekend. We will be working on data collection and manipulation prior to and immediately following fall break. In addition, students are not collecting much information from their research. By reading books and magazine articles, students gather background information about their projects. I am needing parents to allow students to gain access to various resources by making visits to the library. Wikipedia and ask.com are NOT reliable sources. The internet should be used with caution.

We are working on a lab in class. Students are to type their lab reports with the information that they currently have - Title, Purpose, Research, Hypothesis, Materials and Equipment, and Procedure. We will make observations tomorrow and complete the lab report.

Earth Science
Four States of Matter - Students are to read section 3.3 in the Chemistry packet, define the bold words, and answer questions 1 - 5 in section 3.3 assessment.

What on Earth? Where on Earth?

Life Science
Today, we discussed the possible origins of single-celled organisms. Urey and Miller conducted an important experiment which replicated the conditions of the early Earth. Their results yielded small chemical components which can combine to form proteins. Other similar experiments produced carbohydrates and nucleic acids (DNA). We covered the parts of prokaryotic cells as well as how eukaryotic cells may have developed. Homework is for students to complete their poster and paper for "The Cell is like... " project. All students will be presenting their projects to the class.

Science Fair - I have adjusted due dates for three parts of the science fair:
Answers to questions due 9/23/09
Bibliography notes due 9/23/09
Blank Data Table due 9/25/09

Earth Science
We are continuing to study topographic maps. The homework is for students to complete the last page of the topographic map packet - find the easiest path from one hill top to another. We will be having a test on Friday covering Chapter 1 - Maps, DOGS TAILS, and topographic maps.

This Week: Cells and Topo Maps!

Life Science
Students worked on their posters in class today. This is the only classtime provided to work on "The Cell is like..." project. The homework for tonight and tomorrow night will be to complete the poster and paper. Both the poster and paper are due on Wednesday. Students will present their posters to the class on Wednesday.

Earth Science
Is it a hill or a canyon? What is the slope? Students are working on creating topographic profiles using the contour lines on topographic maps. Practice, practice, practice is the best way to learn. It is a challenge to analyze spatial features, so students will have many opportunities to practice. Tonight, the homework is for students to create a topographic profile using the map in the packet (next to the last page). We will have a test on Friday covering topographic maps.

It's Wednesday ALREADY!

Life Science
We are discussing the parts of the plant and animal cell during class emphasizing the function of the organelles. We are continuing to work on "The Cell is like..." project (see August 31st for more info). Students signed up for a specific analogy yesterday. Tonight, students will complete the following:

(1) Choose either the plant or animal cell to be represented by their analogy.
(2) Make a list of the parts of the cell
(3) Make a list of the parts of their analogy which will represent the parts of the cell (the part of the analogy and the part of the cell should have a very similar function).

Earth Science
We are still working with maps. This week is an adventure in exploring topographic maps - reading the elevation of the contour lines, identifying physiographic features, describing slopes (gentle or steep), and locating stream valleys. Tonight, students are to read about "Locating Yourself on a Topographic Map" and identifiy features #1 through 4 on the next topographic map in the packet.
