8. Lesson 5: acids and bases
Contain Hydrogen

9. Lesson 5: acids and bases
Big Idea #3 – Properties of Bases
taste bitter
feel slippery when dissolved in water

10. Lesson 5: acids and bases
Taste Bitter

11. Lesson 5: acids and bases
Slippery when Dissolved in Water

12. Lesson 6: Identification of Compounds
precipitate - A solid that forms as a result of a chemical reaction. A white solid precipitate may form when aluminum chloride is added to a substance that contains aluminum.
residue- A substance left over as a result of a chemical reaction. The black residue left over from burning fossil fuels or wood is carbon.

* NOT ALWAYS an indicator of a chemical reaction

21. Lesson 6: Identification of Compounds
Changes in Color
* NOT ALWAYS an indicator of a chemical reaction

22. Lesson 6: Identification of Compounds
Release of a Gas
* NOT ALWAYS an indicator of a chemical reaction

23. Lesson 6: Identification of Compounds
Formation of a Precipitate
* NOT ALWAYS an indicator of a chemical reaction

24. Type your answer in the chat box!
REVIEW TIME!
Type your answer in the chat box!
Name 2 indicators that a chemical reaction has occurred.

25. Raise your hand to be given the microphone!
Is a change in temperature ALWAYS an indicator of a chemical reaction?
Defend your answer: WHY? or WHY NOT?

26. pH test for acids and bases flame test for metals and carbon
Exit Ticket: Use the polling tool to answer the question before you exit the room.
Which of the following methods can tell you whether there is a particular compound or element in a product or reaction?
pH test for acids and bases
flame test for metals and carbon
iodine test for starch
all of the above

27. ABOVE AND BEYOND…..

28. Use this time wisely! = I need help or have a question. = I finished!
Today you will be working to complete any of your unfinished Science Lessons #1-7.
= I finished!
