Physical Properties of Matter – Chemical Properties of Matter 45+ Page Packet (Middle School Chemistry Unit)


This past week, we finished our second chemistry unit on the Properties of Matter. We explored physical properties (which do not change what the object is) and chemical properties.  We did a lot of hands-on activities exploring density and determining the density of various materials.

At the beginning of the year, we spent time first exploring the different states of matter. Then, in this unit we dove into more detail about how matter is classified. Just as scientists classify the living world, they also divide the non-living world into categories. We looked closely at matter: pure substances and mixtures. 

matter-puresubstance-mixturesTopics we explored in this unit included:

  • Elements & Compounds
  • Overview of the Periodic Table
  • Physical and Chemical Properties
  • Activities on Density
  • Mixtures: Solutions, Colloids and Suspensions
  • elements-and-compoundsSolutions: Solvent, Solutes, Saturation Point

We knew from our previous unit that matter is everything that has weight and takes up space. We went on to talk about elements, compounds and mixtures. Elements, of course, consist of just one type of atom while compounds are made of one type of molecule.

We read from a couple different science books including this one: Elements and Compounds, Building Blocks of Matter (affiliate link).

We also worked through a number of worksheets I made for the kids. (And we used review cards to go over the material we had learned as we progressed through this unit.)

matter-element-compound-mixture-worksheetsWe spent time talking about the organization Periodic Table again. (We did a chemistry unit last year that went into detail about the Periodic Table last year as well. I’ll link to some of those posts below). We talked about the four main groups – alkali metals, alkaline Earth metals, halogens and noble gases.

And, we also spent time talking about metals vs. non-metals.  The kids really enjoyed talking about the major elements we have in our body and those that are toxic to humans!

We also spent one day talking about molecular vs. structural formulas again.

Here are a couple of those (of course, the packet contains the answer sheets as well).

periodic-table-worksheet-molecular-vs-structural-formulaNext, we went on to talk about the physical properties of matter.  We spent several days brainstorming this list… how we can tell different substances from another. Things like… Size, Density, Mass, Volume, Color, Freezing point, Boiling point, Viscosity, Flexibility.  Over the course of several days we wrote out our list (and continued reviewing some of our chemistry cards).

density-activitiesdensity-cubeswater-displacement-density-activityWe did a couple of worksheet pages about calculating density:

density-worksheetWe purchased a number of science materials specifically for this unit.

Are these totally necessary? (I know many homeschoolers are on a tight budget.) Well, at this point I have two middle school-age kids so I really felt like doing some lab work with calculations (and a lab report) were important skills for them to build.  At the very least, you would need a graduated cylinder and a scale to be able to make calculations about density.

We spent just one day talking about chemical properties – things like rust, tarnish, radioactivity, etc.  The kids will go over this in much more detail in another couple of years.

In the last part of our unit we talked about mixtures. We talked about the difference between solutions and suspensions.  I had the kids do a worksheet about homogeneous (with examples like water and mouthwash) and heterogeneous mixtures (with examples like pizza and sand) to help them understand that some things mix thoroughly and others don’t.

We went over the difference between a solute and a solvent… and did a couple of hands-on activities to explore those.

As I said above, we spent time each day going over the material in this unit. Some things were new and challenging for my kids.  As with most of our units, I’m sure we’ll have to return to this material again in a couple of years!


We did this unit directly after our States of Matter Unit.  This Physical and Chemical Properties of Matter Unit was mainly for my older two kids who are currently 10 and 13, Grades 6 and 8. This packet is 45+ pages.

I have more than a dozen hands-on activities planned for this unit… everything from building simple and parallel circuits, to doing paper circuits and building a small motorized robot!  Stay tuned for that!  Here’s a sneak peek:
