Today we observed our Abundance and Distribution of Bacteria lab. Some of you grew some weird looking critters! See Monday's post for a link to this lab. Next we did another microbiology lab: Antibiotics vs. Bacteria. This lab is found HERE. We started incubating these petri dishes and will observe them on Friday.
See the video below for a description of bacterial colonies:
Today we took notes on Thermal Energy Calculations. These notes are found HERE. Next we did some thermal energy practice questions. These are HERE. Finally, we prepared for the RUBE GOLDBERG chain reaction. See the videos below.
Today we did the Abundance and Distribution of Bacteria Lab. We swabbed some areas in the school and started off growing the bacteria. Next we finished notes and started the review assignment and A/E block watched the videos below:
Today we finished off the notes in the bacteria unit. These notes are found HERE. Make sure you take notes on pathogenic bacteria, helpful bacteria and how to control the spread of bacteria. Next we started to organize for our lab: Distribution and Abundance of Bacteria. This lab is found HERE. Finally we got our bacteria review for our bacteria final assessment on Monday, April 27th. This is found HERE.
Today we started off with some review questions on PE (Gravitational Potential Energy) and KE (Mechanical Kinetic Energy) questions. Remember to:
1) Write out the formula you used. 2) Write out what is given and what you are trying to find. 3) Substitute the numbers into the formula. 4) Give you answer clearly (in a box) with units
Worksheet is found HERE. This is due tomorrow.
Next we took some notes on Thermal Energy. These notes are found HERE.
Today we continued taking notes on Bacteria. We wrote notes on how bacteria get their energy and what there oxygen requirements are. Power point is found HERE (slide #27-29). Next we did a poster carousel project where we went around and gathered some information from each poster.
Today we took notes on KE and PE together. These notes are found HERE. Next we did a poster presentation carousel activity where we walked around and looked at other peoples energy projects.
