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.

Tuesday, November 23, 2010

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!

Monday, November 22, 2010
