DAY 4-Thursday Kickoff:
Pencils down! Wait for Mad Minute Mad Minute A chemical reaction that releases thermal energy is called _________________. A chemical reaction that absorbs thermal energy is called _________________. Is energy ever created or destroyed in a chemical reaction? _____________ The Sun produces heat and l ight by fusing hydrogen atoms into helium atoms. Do you think this process is endothermic or exothermic? The chemical Freon is used in refrigerators to make them cold. Do you think this process is endothermic or exothermic?

Vocabulary Carbohydrate – Exothermic Process –
Quest ions How does your body turn food into energy? What happens to bonds in chemical reactions?
In an exothermic reaction, how does the energy of the products compare to the energy of the reactants?
Endothermic Process Indication – a sign that something is occuring
Why isn’t ice melting in your hand a chemical reaction? What is one indication that dissolving ammonium nitrate is an endothermic process?
How does the energy of the products compare to the energy of the reactants in an endothermic reaction?

DAY 5 - Friday Kickoff: Review and correct this week’s kickoffs Review/Reteach/ Work Period
FINAL EXAM NEXT WEEK
It covers everything we have done this semester:
History of the Atomic Model Periodic Table
States of Matter Changes in States of Matter
Radioactivity Compounds
Acids & Bases
A good place to review would be Chapter Content Mastery Worksheets, other worksheets, notes, and of course the book. Also, the website is good if there are
