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.

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!

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.
