Wednesday 2.9.11

Announcements: Instead of having 7 quizzes we'll only have 6. We took a quiz today, and we're taking another  quiz tomorrow
Homework: pg 32-34 due tomorrow, Web assigns, and text questions due before the test 2/15


Today we worked on part one of our lab. We did all of the following steps listed in the picture below. To sum it up, we basically just put copper (II) chloride in water and stirred it until  the copper (II) chloride dissolved. Then we massed the nails and recorded data. After that we put the nails in the solution. We will come back to doing the lab tomorrow.

After we finished part one of the lab, we took a quiz on limiting reactants. When we finished the quiz, we used the rest of the class time to work on our homework. (pg 32-34, mentioned in bold above)

Tuesday 9/28/10

Black container that contained the bead. There were 12 different containers with differents line patterns inside of them.
(scroll down all the way for more details)

Black box lab

We did this sheet in class. The sheet had four atom scientists' names and we had to fill out information about them. The information can be found on the colored sheets pictured below.

These are the colored sheets of paper with the information on  four atomic scientists. (Dalton, Rutherford, Thomson, Bohr)

2nd part of the black box lab
Today in class, we started a new unit. We began studying the atomic theory. We did the Black Box Lab. In this lab, we had to go to several stations with black circular containers. Each container had a bead inside of it. We would rattle and move the container to determine what type of shapes/lines were inside of the canister. We could determine the shapes by feeling how the bead bounced off the surfaces, and how the bead sounded when it bounced off certain spots of the container. We weren't allowed to open up the container to see the shapes.Then, we would sketch what we guessed was in the container, on our lab sheet. It was sort of like the concept of trying to figure out what atoms looked like, back in the days of Dalton, Rutherford, Thomson and Bohr, who were atomic scientists.

We got four colored pieces of paper with information about 4 different atomic scientists. The information on the sheets of paper can be used to fill out the Atomic Scientists worksheet that we got to do in class.
