Let’s CHECK your knowledge! Chemistry Formative Assessment What is a Chemical BOND? http://www.brainpop.com/science/matterandchemistry/chemicalbonds/

DIY- Did you know? Loud Noise Video The LAW of Conservation of Matter states that matter cannot be created or destroyed, only changed. Loud Noise Video http://www.periodicvideos.com/videos/feature_high_speed_hydrogen.htm

This is a chemical FORMULA. C8H10N4O2 This is a chemical FORMULA. It tells scientist what ELEMENTS are in the compound AND how many of those ELEMENTS are there. Caffeine

C8H10N4O2 What does the C stand for ? What does the H stand for ? How many Carbon’s are in this formula? What does the H stand for ? How many Hydrogen's are in this formula? What does the N stand for ? How many Nitrogen's are in this formula? What does the O stand for ? How many Oxygen's are in this formula?

Video time! On the back of your compound notes is a video sheet to fill out. We will check it when the video is over. http://safari.lcps.org/SAFARI/montage/play.php?keyindex=69273&location=local&filetypeid=54 While we watch… Let’s eat a COMPOUND and drink a MIXTURE!

Quiz on Friday! Homework We can start it together: color the element the color from the key write the formula for the compound you have colored Quiz on Friday!
