Ugh, I wrote a great post and something happened when I was uploading the picture and now it's gone! I found this cell cake and I would like to share it with everyone. It's from The Pioneer Woman website. The cake is covered with frosting and all the organelles are either made of candy or different colored frostings. It's colorful, beautiful, and yummy looking to eat!

Here is what we did today for Cell structure and function. I think it was more successful than doing this with Jello. They had to construct the ten organelles I wrote on the board and write down their functions as well. They did an awesome job! I hope it helps them on the exam next week. I walked around and asked questions while they were making their cells.

I will be starting my units on Photosynthesis and Cellular Respiration soon and I was wondering if anyone has any ideas for fun, short labs or activities we can do. I have the Elodea lab that measures oxygen levels in the test tube and I just learned about a lab that uses little disks of spinach leaves to test photosynthesis. I still need to learn that one. Any advice and opinions will be greatly ...

4 Food Chains and Webs
I used this SciGuide to create an activity for my Biology classes when we were doing the unit on Ecology. I liked this activity because the students got to use their hands for something other than taking notes, and there was an actual end product that the other students could compare and contrast between the different groups. I had the students cut out and paste the various organisms onto half index cards and create their food chains and webs that way. The students worked in groups of 2-3 and they were having a blast. I found all the pictures of the organisms (that I could find in magazines) and I color copied them and had multiple sheets for each group. That way the students already had the pictures to cut out and all the groups had the same organisms. I thought that worked out really well. I was proud of myself for thinking to do that in the first place. After they cut out the pictures and started making their flashcards, I let them play for a little while and get used to the difference between food CHAINS and food WEBS. I think after a short while they all seemed to get it pretty well. The last thing everyone did was answer the questions I had on their worksheet and handed it in. I really like this actvity and I will be sure to use it every year from now on.

3 "Reactionary" Skills
I did this activity with my 9th grade Physical Science students to understand the different reaction types. We did four types of reactions: synthesis, decomposition, single displacement and double displacement. We do not have access to computers in class and the computers in the library are always being used for testing so I just went over the different reactions in a lecture form with worksheets. I broke the class into four groups (we only have 18 students in class) and they each got one of the reactions. From there they were responsible for portraying their reaction in an easy to understand form for the rest of the class. I think they all did a good job and we were all laughing hysterically by the end of class. I think it helped them figure out the four types of reactions better.
