In AP Biology, we went over the discussion questions and shared the class data for our second attempt at the catalase enzyme lab. Everyone felt this one was easier to understand and it gave us the opportunity to change some of the conditions for the reaction, such as temperature, substrate concentration and pH. The instructions can be found here. This procedure will be similar to the one we will follow for the photosynthesis lab later in the week.
In Physical Science, we had a research day for our chemical reaction demonstration day. On Thursday, each group will be responsible for carrying out a demonstration of a chemical reaction using common household chemicals. The assignment sheet can be found here.
We found some great websites for cool demonstrations, some of which we will be showing throughout the year. One website was ChemDemo from James Madison University. Another was a list of household and lab chemical demonstrations from Elmhurst College.
