Announcements--Bring goggles if u dont already have them
Homework--Finish part one of the Alka seltzer lab and bring composition notebook
Body--Today in class we started by recieving 7 sheets of paper to tape into our composition notebooks the first 2 were Unit 1 calanders that told us what we would be doin each day and what pages you could find the material on in the book. The 3rd sheet was unit one objectives and the 4th was a Variables practices sheet. The last three are part of the Alka-seltzer lab that we are doin in class
Next Mr. Paek refreshed are memories on some of the scientific terminlogy we will need to know this year. First we reviewed variables which we used a little bit last year
Independent variable--What you change in the experiments, usually on the X axis of a graph
Dependent variable--What you are measuring, usually on the Y axis of a graph
Control--What stays the same
Then we went over 2 different types of data
Qualitative--Observations that are generally subjective
Quantitative--observations that are generally objective
Once we finished with the notes Mr paek pared us up and sent us to the back to work on the first part of the alka-seltzer lab. For this we took 2 tablets of Alka-seltzer and put them in a tiney tube filled with water. We then put the cap on and waited to see what happened. If you did the process right the cap should have shot of because of the chemical reaction between the water and the tablets. You may have done this once or twice depending on how many tablets you put in your first try. We will be doing the rest of the lab tomorow in class.
The next scriber is (and this was completely random) is joshua
