We did a lot of interesting things in class today. When we first went into the classroom we were given an elmo stamp for our stamp sheets if we did the homework.
Then Mrs. Stein explained to us our homework and taught us the difference between a Venn Diagram and a Double Bubble Map. A Venn Diagram has only two circles and a limited amount of space to write the similarities of the two subjects. Where as in a Double Bubble Map you can add as many circles you want.
Mrs. Stein then explained to us the Extra Credit that does not happen often. So if anyone wants to you should defineitly check the Extra Credit section on the blog for more information!
We then finished the notes that we had on Wednesday. We learned about the 3 pyramid.
Pyramid of Energy: This pryamid shows us that only 10% of the energy to one trophic level to the next is transfered. It also shows us that 90% of that energy is used in heat.
Biomass Pyramid: This pyramid shows us the amount of food on each trophic level. There is most likely a greater biomass at the base. For example, all the krills in the oceans weigh more than all the whales in the ocean because whales eat a lot of krill on a daily basis.
Pyramid of Numbers: This pyramid shows us approximately the number of individual organisms on each trophic level. Also in some ecosystems it's not shaped as a pyramid. An example, is that the pyramid could be shaped as a tree.
After the notes we counted our Duckweed lab, but before that Mrs. Stein found a problem. She believes that the lights in the back, where all the Duckweed are put, is too hot and are killing the Duckweed. Therefore we were given the chance to redo our expirement or just go with what we had.
Lastly, Mrs. Stein gave us time to do our homework for the Webquest.
The Next Scribe will be... JULIA!
