States of Matter: Changes

Grade 5 Science:  States of Matter:  Changes

Getting Started, something to get us thinking about changes in state.

When have you observed a material undergoing a change of some kind?

Reversible and Irreversible Changes

Check out this interactive online lab activity exploring reversible and irreversible changes, and how they are different.

Let's try to share all the types of changes.

Vote on the most effective setting poster projects!

 Results to follow.

Results from Character Poster Project

The results are in from the class vote on the most effective Character Posters from last week's homework project.

Students created posters using text features to effective showcase a character from the narrative each student was reading at home that week.  There were a lot of impressive posters, and the students selected their favourites.

Here is the result of that vote:

Computer Lab Thursday

Today we'll be practicing using an interface we'll be doing a number of things with this year.  It's called a form.

Each partner will be responsible today for filling out this form.

We'll then go back to class and see how the results work.

Solid, Liquid, Gas

Thursday grade 4's will be beginning their study of the regions, provinces, and territories of Canada with Ms. Li and grade 5's will be beginning an investigation of the Properties of and changes in matter.

Here is a link to today's grade 5 science handout.

Today we will be introducing 2 important big ideas:

1.  There are 3 main states (or phases) of matter.  Solid, Liquid, and GaS.

Other more exotic states/phases exist (such as plasma) but are not as commonly experienced.

2.  Matter the changes state is still the same matter.

Water that freezes into ice is still water, it's just changed into the solid state.  Water that evaporates or boils into water vapor (or steam) is still water, it's just changed into the gaseous state (changed into a gas).  Every kind of matter can change its state...not just water.  Rocks can melt, or even be vaporized if enough energy (heat) is applied.




So what is matter and how does it change into different states?

Okay, rocks can melt.  I get that.  But what does rock in the gas state look like?
