Final Day of Leaf Disk Assay: Data Analysis (Day 4)

Leaf Disk Assay : Photosynthesis Lab Day 4 (final day)

Learning Objective: I can measure the rate of photosynthesis in a leaf by observing the buildup of oxygen which makes leaves float. I will adjust variables to see its effect on photosynthesis. 

Today you will be doing the data analysis for the lab.

Use the data from your table to complete the graph and answer the results and conclusion questions.

Due by the end of class today for 30 points!

Photosynthesis Lab Data Collection (Day 3)

Leaf Disk Assay : Photosynthesis Lab Data Collection (Day 3)

Learning Objective: I can measure the rate of photosynthesis in a leaf by observing the buildup of oxygen which makes leaves float. I will adjust variables to see its effect on photosynthesis. 

Today you will be doing the actual data collection for the lab.

1. Review procedure and set up materials.

2. Time rate of photosynthesis under different variables and record data

3. Analyze data and work on lab writeup 

IMPORTANT TIPS:
-Add 1 drop of soap to the baking soda solution to wet the hydrophobic surface of the leaf and allow the solution to be drawn into the leaf.
-Use 1 scoop of baking soda per 100mL of water.
-1 scoop of baking soda = 1.5 grams
-Try holding the vacuum for 10 seconds to sink the disks in the syringe
-Every cup has to get the same amount of light per group unless you're testing light type or intensity.

You will have Friday to work on the data analysis: graph and conclusion questions. It will be due by the end of the class period on Friday for 30 points.

Continue Photosynthesis Lab (Day 2)

Quarter 3 Grades were posted on Friday!

WARM UP (4/11/16)

What are three specific goals you have for yourself in biology class for Quarter 4?

1.

2.

3.

This Week: Tutorial Thursday, Assembly Friday

Congratulations go out to all of Franklin's High School Innovation Challenge participants!

This year's theme was "[Re]Fresh Our H2O." Eight high schools teams were invited to design technological solutions to address any problem facing humanity related to freshwater.  

Our team's theme was "Gamifying Water Conservation”. They came up with a revolutionary idea: make saving water fun through the creation of a water conservation app game that tracks our daily, weekly, and monthly consumption, along with other stats, such as fixture usage…They walked away as winners in the "Most Creative Solution" category.

Please congratulate our team for their hard work, they all put in many hours and efforts on this project:

Leaf Disk Assay : Photosynthesis Lab Day II

Learning Objective: I can measure the rate of photosynthesis in a leaf by observing the buildup of oxygen which makes leaves float. I will adjust variables to see its effect on photosynthesis. 

Today you will be doing the actual data collection for the lab.

1. Review procedure and set up materials.

2. Walk outside to gather leaves.

3. Time rate of photosynthesis under different variables and record data

4. Analyze data and work on lab writeup 

You will have the whole class period on Wednesday to work on the graph and conclusion questions. It will be due by the end of the class period on Wednesday for 30 points.

Begin Photosynthesis Lab (Day 1)

Tomorrow is the last day of Q3! Come see me after school today in C13 to turn in last minute work!

Last class we started Chapter 9: Photosynthesis & Cellular Respiration.

Open notebooks to notes to review.
What is photosynthesis? Who? Where? Why?

Today we will a begin a lab to explore photosynthesis further. We will spend the next two class periods working on it. It will be due Wednesday, April 13th for 30 points.

Title - Leaf Disk Assay : Photosynthesis Lab

Photosynthesis & Cellular Respiration notes

WARM UP (4/4/16)
1. What organelles helps plants capture light energy from the sun and convert it into chemical energy?
2. What is this conversion from light energy to chemical energy in plants called?
3. How do autotrophs and heterotrophs obtain energy to grow?



Answers...
1. chloroplasts
2. photosynthesis
3. Autotrophs make organic compounds that serve as food for them and all other organisms on Earth, and have a supply of food as long as sunlight is available. Heterotrophs, however, must consume the food that autotrophs make since they cannot make their own.

OK...LET'S DO SCIENCE!

In Chapter 8 we learned about how cells maintain homeostasis by controlling movement of substances into and out of the cell & how cells communicate...

Now we want to explore how cells get the energy they need to do these tasks.

Begin Ch 9: Photosynthesis & Cellular Respiration

Learning Objective: I can describe the processes cells use to obtain energy.

PHOTOSYNTHESIS: The process by which carbon dioxide, sunlight, and water are converted into carbohydrates and oxygen

-Who does it? plants, algae, & some prokaryotes (we'll focus on plants)

-Where does it occur? inside the chloroplasts, organelles found in plant cells

-Why is it important? it produces glucose and oxygen which are needed for cellular respiration (and sustains all life on earth!)

OVERVIEW OF PROCESS:

carbon dioxide + water + light energy from sun ----> glucose (sugar) + oxygen

Chemical equation:

6CO2 + 6H2O + light energy ------> C6H12O6 + 6O2

THREE STAGES OF PHOTOSYNTHESIS:

1. Light Reactions - energy from the sun is used to split water in an H+ (hydrogen ion) and an O2; oxygen diffuses out of chloroplasts as a byproduct.

2. Light energy is converted to chemical energy; temporarily stored in ATP (adenosine triphosphate) & NADPH (nicotinamide adenine dinucleotide phosphate)

3. Calvin Cycle - carbon is fixed into glucose; fixed = converting inorganic compounds like carbon dioxide into organic compounds like glucose

(left side processing)

CELLULAR RESPIRATION: Process used by humans and most other organisms to release the energy stored in the food they consume.

-Who does it? All living organisms

-Where does it occur? Step 1 occurs in cytoplasm, the rest of the process occurs in the mitochondria of plant & animal cells

-Why is it important? It produces ATP, the fuel needed by cells to perform all necessary functions and maintain life!

OVERVIEW OF PROCESS:

glucose + oxygen ---> carbon dioxide + water + energy

Chemical equation:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP (energy)

THREE STAGES OF CELLULAR RESPIRATION:

1. Glycolysis: occurs in cytoplasm of plant & animal cells; glucose is broken down into 2 pyruvate molecules.

2. Krebs Cycle: takes place in the matrix (inside) of a cell's mitochondria; breaks down pyruvate into carbon dioxide, or CO₂.

3. Electron Transport Chain: takes place in the inner mitochondrial membrane of cells; electrons and hydrogen ions (H+) are shuttled across the mitochondrial membrane to produce ATP for energy.
