Students will be able to learn more about properties of matter, and, they will use Polymers to observe properties of matter.
What should students know as a result of this lesson?
What should the students be able to do as a result of this lesson?
Before the lesson on Polymers Matter!, students will be given a pretest on their knowledge of matter:
Assessment: Through discussing the questions with the students, determine that they have a basic understanding of matter, polymer, and physical properties of matter.
Give 10 grams of Polydoh moldable plastic to each student and ask them to make a chart to list the properties of polymer before the experiment.
Create a simple table with columns for the students to record their observations about the physical properties of their polymer "before" and "after" conducting the experiment.
Give 5 minutes to students to fill in the "before" section of their chart/table. Then have a discussion about their findings.
Then start to pass out the rest of the materials.
A styrofoam cup
(Teacher should have the control of the hot plate and water)
Have the students put the Polydoh in hot water that they have in the styrofoam cups.
Ask the students to record their observations.
After the Polydoh becomes clear, ask students to take them out using the spoon. And start to shape it.
Ask students to fill in the "after" section of their chart/tables.
Give them 5 minutes for that.
And have a discussion of their findings.
At the end, have students take the Post-Quiz.
Students will need to know lab safety.
[Clarification Statement: Emphasis is on understanding the strengths of forces between particles, not on naming specific intermolecular forces (such as dipoledipole). Examples of particles could include ions, atoms, molecules, and networked materials (such as graphite). Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.] [Assessment Boundary: Assessment does not include Raoult’s law calculations of vapor pressure.]
Develop a model based on evidence to illustrate the relationships between systems or between components of a system. (HS-PS1-8)
Use a model to predict the relationships between systems or between components of a system. (HSPS1- 1)
Arts and crafts, You can do anything you want to do with it.
Students will be assessed using a Pre-quiz and Post-quiz.
