Science with Mr. Dowst!

Today we started Chapter 3:  Get a Charge Out of Matter! As the title suggest, we’ll be learning about positively and negatively charged matter. This will continue our investigation into the microscopic nature of matter.

The Learning Targets for this Chapter are:

• Atoms interact due to forces between plus and minus charges.
• Forces of interaction inside molecules result in different types of chemical bonds
• Forces of interaction between molecules result in differences in physical properties

• Writing, speaking, diagrams, and mathematics are required for effective communication

Today we started the Engage section (“What’s Shocking?“) by looking at the conductivity of various solutions.

We saw that the heavier the filter the faster it fell. How long would it take for an infinitely heavy filter to fall??

In-Class Work: Process and Procedure, #1-5

Homework: None

Learning Target: Pure water doesn’t conduct electricity; some water solutions do.

Upcoming: Testing the properites of charged and non-charged compounds to see how they differ.

We wrapped up loose ends the first part of class today. And then filled out self/group evaluations and reflections on the learning targets. Congratulations on being done with Chapter 2!

In-Class Work:  Turn in 1-page drawing of Galilean thermometer and notebook

Homework: Finish reflection on learning targets, if you didn’t get it done in class.

Learning Target:  The particle model explains how the wave toy and other matter function.
