Students drew pictures of their concept of an atom. I then had students post their pictures on the front board and explain them. Many students confused cell with atoms since they both have a nucleus. Other misconceptions were that the nucleus was a separate particle in addition to protons and neutrons and some students incorrectly positioned the electrons, protons, and neutrons.
Handed out Aim 23 - Parts of the Atom. Students read it and answered questions on a separate sheet of paper.
Went over answers.
Quiz next time (Tuesday) on the parts of an atom.
Modeled Sludge T-Shirts for Mrs. Lutes' class.
Students spent last half hour of class working on the reverse side of their T-Shirts.

Day 6 of sludge - Final in class day for lab work
Only make-up is today after school.
Continue to write up second half of report. The final report, both halves together (though I will only grade the second half) are due May 27. Reports are to be handed in at the beginning of class, there will be no time in class to work on them. No late work will be accepted.

Collected first half reports and checked names off list.
Day 3 of sludge.
Several students did the fractional distillation day 1 or day 2. Ran out of equipment so many students had to wait.
Recommended students work on making time vs temperature graph and making data table. Students can also start work on tests for solids.

Day 2 of sludge
The first half of the sludge write-up is due on Monday. It should be typed and have a cover page signed by a parent.
If you did not hand in your hypothesis and only had it stamped, the original stamped hypothesis must also be handed in with the report. Note - this does not replace the typed up hypothesis included in your report.
Several people completed Day 1 of the Fractional Distillation. Many even came in early to get started and be sure they got the equipment.

Day 1 - Sludge
Collected Parent forms for those students who had not handed them in.
Collected hypothesis sheets.
Students started sludge - most did a separation.
For homework, I would suggest writing up the Question, Hypothesis, and Separation of Insoluble solids sections of lab report.

Introduction to sludge. Handed out sludge packet and went through the entire packet explaining in detail what was expected in the write-up for each section of the report.
Those students who had handed in their parent form were allowed to examine their sludge to write their hypothesis.
Before students can get their sludge, they must hand in the signed parent form.
Before students can start analysis, they must hand in a copy of their hypothesis.
We will start sludge labs on Wednesday.

Density test
2 parts: measurements, questions and problems
Set-up 4 lab stations and gave students 10 minutes to make their measurements. Students worked on question and problem section of test while waiting for their turn at the lab station.
Many students had difficulties with the measurements. For reduced credit, I allowed them to go back and try again or even had another student help them.
Bring in parent letter for Sludge on Friday so we can start with the introduction to Sludge.
