Activity #42: A closer look


Today students started their new notebooks. We set up our table of contents and started activity 42 on page 4. Next students watched a power point on the organelles that make up a cell. As they watched the power point, they filled in a chart that had the structures and functions of each organelle. Finally students recorded their quiz grades on their ELG tracker.

Homework: Study for structure/function quiz on Friday!

Due Today: Make sure to have your new notebooks here!

Activity #40: A CELL MODEL


Today students participated in a cell membrane activity. We first reviewed what the cell theory is which states that all living things are made up of cells. Next we talked about our two new words: Cell membrane and cytoplasm. Next we made a model of the cell membrane and cytoplasm. Students watched as the white cornstarch turned purple and the orange Lugols stayed orange. We then discussed the possibilities of why this happened. Finally, we found out that only the orange molecules can travel through the bag(cell membrane) while the white cornstarch molecules were too large to go through the bag. This represents how the cell membrane works. It protects the cell by allowing some molecules to cross the membrane and keeps other things out.

Activity #39: Cells Alive


Today students examined the similarities between human cells and yeast cells. Students learned about cellular respiration. We used BTB solution which is blue when oxygen is present and yellow if carbon dioxide. When yeast carry out respiration, it is in a anaerobic environment where yeast break down sugar and release energy and carbon dioxide which is a waste product. When carbon dioxide is released, the solution turns yellow.

Students also took the 3rd quiz for unit C today!

College Survey Day


Today students took a college survey that looks at their personal characteristics and interests. After students complete the survey, specific jobs and careers are selected that represent the qualities of their survey. Students then research 2 careers to look at the amount of money they could make and the education they will need. We will finish the survey tomorrow!

Quiz tomorrow over Germ Theory!

Activity #37: Part II


Today students continued working on the Germ Theory of Disease Timeline. Each group was assigned one of the twelve scientists that we researched yesterday. Next students had to create a poster that had their scientists last name, important date, and discovery or contribution to help create the Germ Theory of Disease. Students then put all 12 posters together to create a timeline.

Hint: Quiz next Monday over scientists.

Activity #37: Germ Theory of Disease


During block days in Life Science, students will participate in Activity #37: Germ Theory. Students will research the contributions and discoveries of 12 scientists, which all helped to develop the Germ Theory of Disease. As we read, students will first discuss the important date that the discovery happened and the most important discovery for that specific scientist. Next students will complete their timeline worksheet. After the worksheet is filled in for each scientist, students drew pictures to help them remember the major contribution of the scientist. Tomorrow the students will create a life size timeline of the Germ Theory.

Homework Due Today: Plant and Animal Cell Coloring sheets

Math Acuity Testing


On Monday and Tuesday this week students will be taking the online Math Acuity test in science class. Students will work on science fair on Tuesday when they finish the test. Please remember to bring science fair sheet tomorrow!

Homework: Plant and Animal Cells (Coloring sheet) due on block day this week!
