Announcements: Quiz tomorrow (9/2)

Homework: Measurement 3-6, Lab due Friday (9/2), Measurement lab questions

Overview: Today in class we got started on Measurement Lab 1. We grabbed a meter stick, a ruler, a metal bar, a paper clip, a pencil, a nail, and a plastic brick. We measured our height in meters, did some conversion with m-km and for every km, there are 100m. We then measured the square/rectangular object's dimensions and recored each measurement and multiplied each side by each other and that gave us the volume which is always followed by the units (cubed). We then took out the graduated cylinders and found the volume of things that are harder to find like the nail. Finally we used the electronic scales in the back to measure the mass of each object.

Announcements: Quiz on measurements on friday

Homework: finish lab write-up

Overview: Today in class we talked about safety in chemistry, and we watched a science lab safety video. After we finished, we got paapers about measurements and taped them in our notebooks (two to a page). After that, we reviewed the Variables sheet that we taped in our notebooks last week.

answers to variables sheet that we answered in class:

1.

I- amount of water
D- growth of plant
C1-light

C2-type of plant

2.

I-Coffee filter size

D-time to fall

C1-distance it's falling

C2-type of coffee filter

3.

I-type of food

D-temp.

C1-amount of water

C2-time

4.

I- concentration of oxygen
D-growth

C1-type of plant

C2-placement of plant

August 30, 2011 Part 3 of the alka seltzer lab

Announcements: None

Homework: Finish your lab report by this Friday.

Overview: Today in class we got laptops to use in class to start/ finish our lab reports. We got about 35 minutes to do so, and to do it you log on to google docs and add both your partner and Mr. Paek. You and your partner will be able to write at the same time, and Mr. Paek will grade by the seperate colors they come up as. On the lab report, you need to include a graph which is found on moodle. Click the link Make a graph and choose the type of graph you would like. After we finished that, Mr. Paek talked to us about safety and then showed us a lab demonstration. In the demo Mr. Paek took the bubles from dish wash soap and lit them on fire in his hand.

August 29, 2011 - Part 3 of The Alka-Seltzer Lab

Announcements - None!

Homework - Bring goggles and/or safety contract if you have not already done so!

Overview -

It is not just three days anymore, it is the first full week (= 7 days) of the 2011-2012 school year. To start off the Monday, Mr. Paek went over the scribe rules - since it is new to most people. Then, we walked through part 2 of the Alka-Seltzer lab just to save time and go on to part 3. For the remainder of the period, each group got to make their own experiment and end up writing the first two parts of the experimental design which are: Problem and Hypotheses (this order can be found on the third sheet of the lab that is taped in your composition notebook). Tomorrow, we will be working on google.doc to type up our whole experimental design. So try to be here! We did not take any notes and this is all that happened in class today.

The next scribe is..................................... Matthew.

August 26- The First Friday and a Lab Begins

Announcements- Bring/Buy Googles if you haven't done it yet

Homework- None

Overview:

The first Friday of the 2011-2012 school year starts of with notes and then a BANG. We started of taking notes on basic science that most of us learned in 8th grade. For example, variables and basic experiment proceeder. We taped in all seven of our note pages for the unit and then took some extra notes on specific variables.

Independent- the variable that experimenter is changing (light, temperature, location, ext.)

Dependent- the variable that can be measured (distance, health, size, ext.)

Control- the elements in the experiment that stay the same and stay constant

After notes we started an experiment that nearly gave me a heart attack. We added seltzer tablets to film canisters filled with water. The tablets created gas bubbles and if the seal of the canister we tight then when the bubbles built up the canister popped. It was quiet scary and we made many dents in the ceiling.

The next scribe will be .................... Izzy R.!! Wooh!
