1. How do living things use Energy?

2. Objective:  Where do living things get energy and how do they use it?

3. Vocabulary preview sheet  Rate yourself 1-4 on your understanding of each word at this time in the rating before column  4 – you understand the word well enough to explain to someone else what it means  3- pretty sure you know what it means  2- heard the word before, but not sure exactly what it means  1- Never heard the word or no idea what it means.

4.  We will watch a few short videos about photosynthesis.

5. Photosynthesis Photo – light Synthesis- to make Photosynthesis – to make food energy using light energy

6. Photosynthesis  Examples:  Plants and some protists

7. Carbon Dioxide:  A compoundcontaining one carbon and two oxygen atoms. Formula: CO 2

8. Water:  A compound containing two hydrogen and one oxygen atoms.  Formula: H 2 O

9. Oxygen:  A compound containing two oxygen atoms.  Formula: O 2

13. Put it together and what do you get? Formula:_Sunlight___ CO 2 + H 2 O = O 2 + C 6 H 12 O 6 Photosynthesis: Carbon dioxide + Water = Oxygen + sugar

15. Respiration:  When an organism makes kinetic energy using food energy.  Reverse of photosynthesis  All organisms do this even plants.

17. Respiration Formula: _Kinetic Energy_____ O 2 + C 6 H 12 O 6 = CO 2 + H 2 O

19. Complete the T-Chart that compares how photosynthesis and respiration are similar and different: SimilarDifferent

20. Diagram of photosynthesis and respiration  Use the words, pictures and arrows to show the processes of photosynthesis and Match the words with the formulas.  Once completed, raise your hand to get checked.  Then draw the picture and explain in your journal.  Do the same for respiration
