Presentation transcript:

Warm-Up  Explain what variable your group decided to manipulate for the experiment today.  Write down a quick prediction about what you think will happen.

Learning Targets  Learning Target: Students will understand the individual parts and overall format of the “Official” Investigational Design.  Learning Target: Students will have a basic understanding of surface tension.  Today we will continue working on “Official Drops on a Penny.”

Scientific Note: Surface Tension  The surface tension of water is caused by the attraction of water molecules to each other. Just as a magnet is attracted to things of metal.  Water molecules are attracted to each other because of hydrogen bonding.  Surface tension allows some things to float.

Surface Tension

Before you start the lab…  You must have all of the Pre-Lab completed including an organized data Table.  Make sure you also have a Procedure (with a diagram) completed.

During the lab…  Gather your data and complete “Official Drops on a Penny”  This includes:  A graph of your trials and averages (bar graph).  Conclusion (look at your 4 bullet points).  Discussion of results.  We will be grading this tomorrow! Make sure it is your best work!

Homework  Finish Official Drops on a Penny Investigation, due tomorrow!  Use the yellow sheet as your guide. All parts need to be included!  Remember not to rush and do your best!

Warm-Up  Explain what went well during your lab yesterday.  Explain what you would do differently next time.

Learning Target  Learning Target: Students will set goals for the year and receive feedback on their lab write-up.

Goal Setting  Setting Goals:  Thoughtfully fill out the blue goal sheet. I expect a few sentences in each box regarding Science.  These will be kept all year and re-visited at progress report time.

Official Drops on a Penny  Review and finish any parts to your Official Drops on a Penny Lab.  Look carefully at the Yellow Sheet to make sure you have answered all parts!  Be ready to grade another student’s lab report.

Grading the Lab  1. Give honest, constructive feedback to the individual.  2. Do your best and read all handwriting.  3. Use the Lab Handout to guide your grading.  4. Use the rubric to assign specific points.

Homework  Have a great weekend! GO BEAVS!
