Lesson Descriptions
Day 8 - Phases of Matter - Solids, Liquids, and Gases: This unit will start off with an introduction and a recap of the states of matter of a solid, liquid, and a gas. The students will be able to draw pictures of how the molecules of solids, liquids, and gasses behave. There is a short video to be shown by Bill Nye the Science Guy about matter, and then the students will go briefly over notes. They will then perform a lab with dry and regular ice, and seeing some properties of the states of matter.
Day 9 - Heating and Cooling Diagrams: The most common diagrams to go over include how the different phases change as heat is either added or taken away from the substance. This unit will go over those basics, so more in depth talks about phase diagrams and chemical/physical properties can be discussed the next day.
Day 10 - Physical and Chemical Properties / Intro to Phase Diagrams: The unit will continue with how matter has different chemical and physical properties. This coincides with what was talked about on days 8 and 9, since chemical properties change between differences in phases, but actually changing the phase is a physical change. This information will start with a series of demos as an informal assessment to see if students understand these differences. The students will then be previewed on phase diagrams, which will be continued the next day.
Day 11 - Phases Lab Day 1: The lesson will begin to wrap up with a lab for the students to perform. The lesson will begin with a bell ringer for the students to recap their knowledge on phase diagrams and the difference between chemical and physical changes. This lab activity is for the students to construct their own phase change diagram. This will be done by having the students measure the change in temperature over a span of time. They will see that their diagrams level off at certain points, and that the heat can only be used to either change the phase or temperature. It can't be both at the same time. This method of learning through inquiry is very important because it is getting the students thinking about how to construct their own models, and just how exactly these diagrams are helpful in the way they are constructed.
Day 12 - Phases Lab Day 2/ Mini Unit Quiz: This sub-unit will conclude with letting the students finish the lab from the day before if they didn't finish, going over very briefly what they have covered in this unit, and they will then take a mini unit quiz that will be constructed to test their knowledge on providing their own phase diagram for an unknown compound given a certain amount of information. The test will also ask them to give 3 examples of each a chemical and a physical change. To make this assessment more fair, I will make sure to give students the option of multiple choice questions, short answer questions, and even questions where they can draw diagrams to express ideas.
