We have a bran-new 50+ page packet on the three states of matter – solids, liquids, gases and changing states of matter. We talked quite a bit about the characteristics of solids, liquids and gases. We also went into a lot of detail on the changing states of matter covering those six changes (melting, freezing, evaporation, condensation, sublimation, deposition). In this packet there are various notebook pages, worksheets, lapbook (interactive notebook) pieces, sorting cards, cut-and-paste activities and more! I included the hands-on activities that helped this unit come alive!
We covered the three states of matter years ago, but I realized ED was so little she might not remember doing this topic. Sure enough, when I asked her this summer she was vague and said she needed some review. Since many of my readers have a wide age-range of kids this packet has material that can be adjusted for use with multiple ages. (ED is now 8, Grade 3.)
By the way, someone pointed out that plasma is also a state of matter. That’s true and I talked about that briefly with my kids…. Plasma is a state of matter that is similar to gas, but plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely. A gas becomes a plasma when it is heated until the atoms lose all their electrons, leaving a highly electrified collection of nuclei and free electrons. [My son (in middle school) was particular intrigued by plasma, but it went over my youngest daughter’s head.] This packet does not touch on plasma at all. Just wanted to make sure that is clear. 🙂

The cost of the Three States of Matter Packet is $4.00.
Once you pay for this packet, you will immediately receive a link to download this file (which will open in a browser window). You will also receive an email from Sendowl (the service I use), which will have a link you can click on to download the States of Matter unit. (It will go to the Paypal address you provided and will say, “You can download your digital products…” with a clickable link. It may take a few moments to arrive.)

Note BUNDLE OPTION below: If you want to purchase a bundle with the Properties of Matter Packet, see details below.
Molecules behave differently depending on what state they are in. The molecules in a solid are packed more tightly, while liquid molecules can slide and move past one another. In gases the atoms and molecules are able to move freely about. We did an activity with pony beads (several years ago we did it with marbles), to demonstrate molecule movement.
We talked about the various characteristics and properties of solids, liquids and gases. There are a couple of notebook pages and a foldable that ED added to her science notebook. The photo below was one the kids did a number of years ago, but there are also printable templates in the packet.
The same day we talked about several of the characteristics of solids:
- They resist being pulled apart.
- Elasticity: the solid can be bent or twisted a certain amount and it will return to its former shape
- Malleable – the solid can be formed into a new shape.
We read p. 38 of a Chemistry book called Chemistry: Physical and Chemical Changes in Matter (affiliate link) which we have used for this unit and for the next one (we did on matter: elements, compounds, mixtures, physical and chemical properties.)
I brought out rubber bands to emphasize the concept elasticity. To help explain how something is malleable, I gave them each a sheet of aluminum foil to create their own little critter:
In previous posts I shared some of the activities we did as we talked about the characteristics of liquids and gases.
The kids were pretty comfortable identifying which state of matter basic materials fall into, but I know many of you have younger kids so I included some Montessori-style sorting cards and several different states of matter worksheets:
ED and DD both spent some time sorting the characteristics & properties of matter onto the sorting mat:
We also spent time talking about the changing states of matter. When different substances are heated or cooled they can change properties. For instance, when warm air is cooled it can form condensation. Or, when liquids heat up they can evaporate. There are a number of different worksheets and notebook pages about the changing states of matter:
Changes in States of Matter: We had to spend quite a bit of time on sublimation and deposition. Yesterday I shared some of our hands-on activities for studying the change from a solid to a gas and from a gas to a solid.
And, as always we had a lot of fun with some hands-on activities. I shared those in the packet as well, but ED really enjoyed playing with cornstarch and water (and debating whether it is a solid or a liquid…)
Cornstarch: Is it a solid or a liquid?!!
Is shaving cream a solid or a liquid?
After finishing this unit, we went straight on to our next unit, the Physical and Chemical Properties of Matter ($4.00).
In this unit we are studied:
- Matter: Elements, Compounds, Mixtures
- Organization of the Periodic Table
- Molecular vs. Structural Formulas
- Describing Matter: Physical and Chemical Properties
- Density Activities – Mass÷Volume
- Mixtures: Solutions, Colloids and Suspensions
Another option is that you can purchase a bundle with the States of Matter Packet and the Properties of Matter Packet for $6.00.
$6.00 for the Bundle

- Earth Science Packet: Plate Movement, Earthquakes Volcanoes and more!
- Animal Unit Packet: in this unit we covered the types of animals (both vertebrates and invertebrates), animal characteristics, plus activities on domesticated vs. wild animals and also on animal tracks. There are also some materials on animal habitats and food webs, but we’ll go into much more detail in the 2nd half of this unit. This was made more for my 2nd grader, though it was great review for my older kids.
- Ocean Unit: Last year we did a huge unit on the ocean (right after our biology unit) and did lots of hands-on activities about early navigation, ocean depths, ocean features, tides, salinity and more! We learned about marine habitats, tides & currents, ocean life, bioluminescence and other topics.
