1 Part 1: What s In A Leaf? Reactants YIELD products Reactants: the substances that are required (go in) Products: the substances that are produced (go out)
2 Part 2: Card Sort Practice Notice that you have 2 sets of cards. CHEMICAL FORMULA CARDS WORD CARDS Try your best to match each chemical formula card with the corresponding word card. CO 2 : carbon dioxide H 2 O: water C 6 H 12 O 6 : glucose O 2 : oxygen : yields
3 Let s Practice! Arrange your CHEMICAL FORMULA CARDS into the chemical equation for photosynthesis. CHECK YOUR ANSWER! Fill in the blanks for the chemical equation on your handout. (#3)
4 Let s Practice AGAIN! Arrange your WORD CARDS into the chemical equation for photosynthesis. CHECK YOUR ANSWER! Fill in the blanks for the chemical equation on your handout. (#4)
5 Write the words that best complete the statement below. According to your equation, the process of photosynthesis uses Carbon Dioxide, water, and energy from the Sun to produce Glucose and Oxygen.
6 Part 4: Putting It All Together 5. What type of energy is used in photosynthesis? solar (sun) 6. Is the energy source a reactant, product, or neither? neither 7. Photosynthesis typically occurs in what type of organism? plants 8. Where are CO 2 and O 2 found in the environment? the atmosphere 9. What organelle does photosynthesis take place in? chloroplast
7 Part 4: Putting It All Together 10.What is the overall purpose for photosynthesis? To make sugar (stored energy) that the plant will convert into useable energy (ATP).
8 Part 1: Cellular Respiration Use the diagram to answer questions 1-2.
9 Part 2: Putting It All Together 1. Arrange your pieces into the chemical equation for cellular respiration. Write this equation below: (Use the NAMES of the molecules) According to your equation, the process of cellular respiration uses and to produce and release.
10 Solution Station 3. Glucose, ATP 4. Plants AND animals 5. Oxygen: atmosphere release by plants Glucose: made in plants, consumed by animals 6. Mitochondria 7. Convert glucose (stored energy) into ATP (usable energy)
11 Part 3: Putting Cell Energy Together 9. What are the two main differences between the chemical reaction for photosynthesis and the chemical reaction for cellular respiration? Cellular respiration produces ATP (useable energy), while photosynthesis makes food. The products of one equation are the reactants of the other (minus ATP)
12 Part 3: Putting Cell Energy Together 10.How are photosynthesis and cellular respiration related (similar)? The products for photosynthesis are the reactants for cellular respiration. The products for cellular respiration are the reactants for photosynthesis. They both use/make Oxygen, Carbon Dioxide, Glucose, and Water
13 Snails and Elodea Lab - Light
14 Snails and Elodea Lab (exp. 1) What is in the test tube? Beginning color of test tube. If placed under a LIGHT, what do you think will happen to the color of the test tubes and WHY? Results (After 48 hours, what DID happen) Test Tube #1 Just water Blue Test Tube #2 Test Tube #3 Test Tube #4
15 Results from the LIGHT experiment One of the test tubes turned yellow, meaning excess CO 2 was present in the test tube with only the snail. 1.What cellular process took place that caused the color change in the test tube with the snail and water above? 2.Why did the other test tube containing a snail not change color?
16 Snails and Elodea Lab - Dark
17 Snails and Elodea Lab (exp. 2) What is in the test tube? Beginning color of test tube. If placed in the DARK, what do you think will happen to the color of the test tubes and WHY? Results (After 48 hours, what DID happen) Test Tube #1 Just water Blue Test Tube #2 Test Tube #3 Test Tube #4
18 Results from the DARK experiment Three of the test tubes turned yellow. 3.Explain what would caused the liquids to change color.
19 Aerobic respiration: Uses Oxygen to break down glucose (sugar) molecules into the products carbon dioxide, water and 36 ATP. Anaerobic Respiration happens when there is a lack of (Doesn t have any) Oxygen. It is the breakdown of glucose (sugar) molecules and produces only 2 ATP.
20 There are two types of anaerobic: Lactic Acid Fermentation: This happens during strenuous exercise when your body is not getting enough oxygen and causes cramps and a burning sensation. Alcoholic Fermentation: Used in yeast cells to make bread
21 Based off what you know about Oxygen and ATP output, try and label the two equations below as either anaerobic or aerobic. Aerobic Respiration Anaerobic Respiration
22 Part 5: Concept Map of Cell. Resp. Cellular Respiration Aerobic Respiration Anaerobic Respiration Alcoholic Fermentation Lactic Acid Fermentation
23 Putting Together the DNA 2. Use tape to tape the Deoxyribose and Phosphate molecules together on each side. These COVALENT bonds are hard to break. Write a C on the tape that holds them together. 3. Write an H on each of your sticky dots. 4. Use these H dots to attach the matching nitrogen bases together. These represent the weak HYDROGEN bonds between the base pairs.
24 DNA Discovery Lab You may work with your partner to complete this handout. Use your DNA molecule to help you discover some interesting facts about the structure of DNA and how it replicates. If you have a question, please raise your hand. When you finish, you may help your classmates seated around you.

26 Let s Practice! Try to sing the song with your eyes closed. Only look if you have to! We love DNA made of nucleotides. Phosphate, sugar, and a base bonded down one side. Thymine and adenine make a lovely pair, cytosine without guanine would feel very bare.
27 DNA Booklet DNA is composed of. The Deoxyribose sugarand the phosphate are always the same. The component that differs is the nitrogenous bases (or nitrogen base). BASE PARIRING RULES Adenine always pairs with. Thymine Cytosine always pairs with. Guanine nucleotides

30 What is DNA s job? DNA is like your body s instruction manual. DNA carries the information that tells your cell s how to replicate. All living things must have DNA. The only thing that makes you look different from another living this is the sequence (order) of the nitrogenous base pairs.
