Density Lab

  1.  Hand back section 7.1 worksheet – do you need to do any corrections and resubmit your worksheet?
  2. Hand in Check Your Understanding questions p.271 #1-5
  3. Do:  Density Lab.  See copy of lab here:  Density Lab
  4. HW:  Brainstorm ideas for your science fair project.  Starting next week, make time to talk to me about your ideas.


  1.  Go over article questions for “Cleaning Up Soiled Sites”
  2. Go over section 7.1 worksheet answers.  Hand the worksheet into the hand in folder.
  3. I will be able to compare the density of different objects.
  4. Read section 7.2 (p.260 – 265) and do the Check Your Understanding questions on p.271 #1-5 in complete sentences.

Identifying Variables and Controls

  1.  I will be able to identify the independent and dependent variables and controls in an experiment.
  2. We read through pages 476 to 478 in the textbook together and discussed the vocabulary terms.  The “manipulated” variable is the same as the independent variable.  The “responding” variable is the same as the dependent variable.
  3. Activity:  Look at past project displays.  Answer the questions in your journal.  See questions here:  Looking at Past Projects
  4. Read the article “Cleaning Up Soiled Sites” and answer the questions at the end.  See a copy of the article here:  Cleaning Up Soiled Sites
  5. Make sure section 7.1 worksheet is completed for Wed.

Library Day #2 – Bibliographies and Brainstorm Ideas

  1.  Today, students met in the library to learn how to keep track of their sources in a Bibliography (or Works Cited section).
  2. Students had time to begin brainstorming ideas for their science fair project.  Start with things you enjoy/like/are interested in.  What could you change in that topic area?  What could you measure?
  3. For next class:  finish the section 7.1 worksheet

Library Day #1 – Library Resources

  1.  Today, students were in the library for a lesson on academic honesty and they learned how to access the library online resources.
  2. Finish the library handout.  You can access the library website from home.  If you are having troubles, ask the librarian next class.
  3. Meet in the library next class. Bring your journals!

Thermal Expansion and Contraction

  1.  Go over Science Celebration handout –do you have any questions about the project?
  2. Hand out Journals to students to use (If you didn’t get one, come see me for one)
  3. Demo:  Ball in ring.  At room temperature, the ball fits through the ring.  When we heat up the ball, it no longer fits through the ring.  Why?  How does this relate to the Kinetic Molecular Theory?
  4. Do:  Worksheet for section 7.1 (pages 100-101).  See copy here:  Sec.7.1 Workbook

Designing Experiments

  1.  Review of the Smarter Science handout and how to design a controlled science experiment.
  2. Do:  Testing the Durability of Toilet Paper Lab Activity.  Remember that for it to be a controlled experiment, you can only change one variable at a time.  All other variables must remain identical for each test trial you do.  Gather your data and you will share your results with the class next day.
  3. For homework:  Read at least pages 1, 2, and 5 of the Science Celebration handout for next class.  If you have time, read the whole handout!  See copy here:  Science Fair Outline for 2019-20 ver1

Designing Science Experiments

  1.  Go over lab safety test (block 3 and 4).
  2.  I will be able to explain what happens when energy (heat) is added to matter.
  3. Demo:  Put hot water in Erlenmeyer flask with balloon over the opening of the flask.  When the flask is put into an ice bath, the balloon gets sucked into the flask.  Why?
  4. I will be able to design a controlled experiment.  See Smarter Science handouts here:  Smarter Science Steps to Inquiry 1
  5. Demo:  durability of toilet paper.  We made observations, wrote questions we had about the demonstration, brainstormed what we could have measured and what we could have changed.
  6. In groups of 3, students chose one thing that could be changed (i.e. the type of toilet paper, the number of drops of water added to the toilet paper, etc….) and we will measure how many pennies the paper can hold before it breaks.
  7. Fill out page 3-4 in the Smarter Science booklet for the experiment your group has chosen to do.
  8. Next class, you will be testing it out!

Locating Safety Equipment in Our Classroom

  1.  I will be able to know how to evacuate the building safety and know where to meet my teacher so he/she can record that I evacuated safely.
  2. Go over section 2.1 worksheet on HHPS and WHMIS symbols.  Keep this worksheet until next class so you can study from it.  You will hand in the worksheet next class.
  3. I will be able to locate lab safety equipment in our classroom.  Draw an outline of our classroom.  Label the lab safety equipment on your diagram.
  4. Lab Safety Test next class (Wed Sept 18 for blocks 3 and 4;  Tues. Sept 24 for block 8).  Test outline:  10 True/False questions, diagram in which you label the location of lab safety equipment; matching WHMIS symbols to their descriptions; 5 scenarios in which you identify what the students are doing that is UNsafe and what they are doing that IS safe.
  5. Video on Lab Safety:
