1. Mind Stretcher 12/12/17
Explain the difference between diffusion and osmosis.
Diffusion- gas and liquid molecules
Osmosis- WATER molecules only

2. Read the Background Info now…

3. Set up Gummy Bear Lab:
1. Write a prediction/hypothesis to answer the question written at the top of your lab sheet. 2. Fill out “BEFORE soaking” data in the table by measuring with a ruler 3. Determine MASS using an electronic balance…push ON and then TARE before putting gummy bear on balance. 5. Write initials on TAPE on side of cup, place gummy bear inside and fill with water until it covers gummy bear 6. Place in back of room until next class!

5. Describe Photosynthesis
The process of changing light energy to chemical energy which is stored as sugar
Occurs in plants and some algae
Plants need sunlight, Carbon Dioxide (CO2 ), and Water (H2O) as REACTANTS
Describe Photosynthesis

6. Occurs in the ____________of plants
___________is the green pigment inside chloroplasts that absorb sunlight
chloroplasts
Chlorophyll

7. As the chlorophyll in leaves decays in the autumn, the green color fades and is replaced by the oranges and reds of carotenoids.

CO₂ O₂
H₂O
Glucose
CHLOROPLASTS. Performs photosynthesis. It will take water and carbon dioxide, and change it in to oxygen & glucose… it’s a very simple process.

10. The Photosynthesis Song

11. Photosynthesis:
Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose.
RELEASES…
MAKES…
carbon dioxide + water + light glucose + oxygen
6CO H2O + light C6H12O O2

12. Photosynthesis:
Photosynthesis is the process by which the energy of sunlight is converted into the energy of glucose.
carbon dioxide + water + light glucose + oxygen
REACTANTS PRODUCTS

13. Photosynthesis:
Photosynthesis is the process by which the energy of _________ is ________ into the energy of __________
carbon dioxide + water + light glucose + oxygen
______________ ______________

14. What happens during photosynthesis?
Sunlight provides the energy needed to change carbon dioxide and water into glucose
Oxygen is released as a waste
What happens during photosynthesis?

15. What happens during photosynthesis?
Carbon dioxide enters the leaf through holes called stomata
CO2 combines with the stored energy in the chloroplasts through a chemical reaction to make glucose
The sugar is moved through tubes in the leaf to the roots, stems and fruits of the plants
Some of the sugar is used right away by the plant for energy; some is stored as starch; and some is built into plant tissue

16. Why is this important to us? **Write on bottom half of sheet!!
Without photosynthesis, plants wouldn’t exist.
We cannot make our own food (glucose, energy), we must get our food from plants.
The oxygen released is necessary for
ALL living things.
Remember: Producers/Plants are the base of the food chain!

24. Gummy Bear Lab Day 2 Gently roll bear from cup onto flat paper towel
Measure the height & width of your bear FIRST!!
Measure mass- Push TARE with wax paper ON electronic scale; Gently roll bear from paper towel onto scale. Record (g) and slide bear back onto paper towel.
Record descriptive characteristics in the chart.
Calculate the percent change…example is class set provided. You may use a calculator/device for this...SHOW YOUR WORK !!
Graph percent change results in a BAR graph.
Answer the analysis questions & turn in.
