States of matter

Chemical Changes

Science Unit 4 is pretty difficult. (Don't you think?) If you want to make sure you understand everything you're learning in class, first, re-read the lesson in the book and then visit these websites:

This is a great video; you can review the definitions of physical and chemical changes and afterwards you can take a quiz to test your knowledge. (Be careful, it's designed for American children so you may have to watch two or three times). In this game you have to choose whether the video is showing a physical or a chemical change. Leave a comment with your score! In this activity, you review if changes are reversible or irreversible. Did you answer the questions correctly?

Extra: If you didn't do well on the last test and more practice, check out this video about Solids, Liquids, and Gases or watch this one about Changing States of Matter

Separating Mixtures and Boiling Points

We have been learning about mixtures for a week or so now, so we thought a few videos on methods used to separate mixtures might be helpful. Also included is a video about boiling points of a few different liquids.Something to think about: Why do different liquids have different boiling points?

Distillation

Filtration

Evaporation vs. Vaporization

Boiling points
