Forces and Plants Edu Obj: We will describe how forces affect plants by completing Edusmart S: What is the net force for each example? Explain your answer.

P: Turgor pressure is… The pressure exerted by water inside the cell against the cell wall.

A: Take notes as we go along. C: Edusmart interactivity. Draw and label each step.

Quiz : Forces affect Plant Growth E: Write 3 sentences about what you learned today about forces and plants

Turgor pressure Lab We will demonstrate forces of nature by examining potato samples TEK 7.7 the student knows that there is a relationship among force, motion and energy DRAW the Pyramid. 1) Label the trophic levels 2)IF the herbivores have 100,000 Kcal, label all The other levels with the correct energy S

Answer while you watch Plant VideoVideo 1. Plants need _______ and_____to keep on going. 2. A ____ _____ surrounds a plant cell. 3. Plant cells push water into the ________. 4. Water in vacuoles provide _______ pressure which makes a plant _______. 5. When cells lose water _____ ______ drops and the plant ________. P

Purpose- we will use potatoes to view how turgor pressure works Infer: write what you know about turgor pressure Materials: Potato samples, hand lens, microscopes A

DATA: create the table of physical properties and record your data How you investigated Salted potatoWater potato Touching Hand lens Tasting Smell Listen (when you break it) A

Analysis: Tell me at least 4 things you can learn from looking at your data chart Conclusion (half page reflection): 1.What did you do? 2. Compare the two samples your observed today. 3. What did you learn? 4.How did this help you understand turgor pressure? 5.Why should you not eat lots of frenchfries C E

Trashket Review We will review for our exam on force, motion, and energy by playing trashkit. S- Did this cat do work in scientific terms. Justify your answer!

Things I need to know for my test: 1. Contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp or standing still. 2. Demonstrate and illustrate forces that affect motion in everyday life such as emergence of seedlings, turgor pressure and geotropism. 3. Diagram flow of energy through living systems including food chains, food webs, and energy pyramids. P

A/C - Trashkit Rules: 1. One person shoots at a time from each group. 2. Must have the correct answer and make the basket first 3. When the music stops you must be seated and quiet to listen to an explaination.

Bob and George are fighting over if a ramp is less work or more work. Who is correct?

If ramps don’t change the total amount of work being done, why do we use them?

Students were conducting and experiment on the photosynthesis. Placed a strawberry plant in direct sunlight and one in indirect sunlight and one in the dark. What is the independent variable?

Based of what you know about energy transformations. In the previous question, Why did the plant with no light not produce strawberries?

What axis does the independent variable go on?
