Students will be able to:
use information from videos from the internet, supplementary texts, and classroom discussions to
-compare and contrast physical and chemical changes.
-differentiate between exothermic and endothermic reactions.
The do now was to write an example of a physical change and a chemical change. For each, students should explain WHY it is THAT type of change.
Students reviewed home learning 6.
Students reviewed what is necessary for notebook check 1. Students should have ALL pages pasted in, which includes inside front and back cover, pages 1, 5-10 and a-o. They should have table of contents completed, and paste in the last page of the table of contents. All notes should be done, including the three questions, the highlighted answers, and the summary at the bottom of the page. All home learnings should be pasted in. FInally, they should teach one of the concepts to an adult, and have the adult write what they learned on page K of the notebook, and sign in the appropriate place.
Students watched a BrainPop on the Property Changes. You can watch the video by going to the following site, scrolling down until you reach property changes. Then click the link and enjoy!

Students took notes on physical and chemical changes, which include:
Physical change-changes the form, shape, state, or size of a substance. Tearing paper is a physical change.
A chemical change changes the substance into a new substance with new properties. Burning paper is a chemical change.
An exothermic reaction is a reaction that gives off heat. It releases heat energy into the atmosphere. An endothermic reaction is a reaction that absorbs heat energy from the environment.
You can tell when a chemical change has occurred because:
-color change
-order or smell produced
-solid precipitant formed
-gas produced
-energy given off in the form of light and/or heat.
The home learning is to get the notebook ready.
Since I have not posted pages a-o before, please look under Saturday, 18 September, 2010 to find all pages a-o.
Each group researched and discussed to come up with other examples of physical and chemical changes.
