Lab#1 - How is a controlled experiment formed?

Lab#1 - How is a controlled experiment formed?

Have you ever wondered whether light or dark clothing would be more comfortable on a hot, sunny day?  Scientists conduct scientific experiments to solve problems like this.  They use a process called the scientific method.

  

Problem

How does color affect heat absorption?

Hypothesis

I hypothesize that…  I believe that….  I think that…  I predict that…

  

Materials  (stuff we need to do our experiment)

Virtual Lab

Procedure  (step by step list of instructions, kind of like a recipe)

Results

--Each data table must have a bar graph accompanying it--

Analysis

1. What was the problem you were trying to solve?

2.  What was the independent variable? 

3. What was the dependent variable?

4. What were your constants?

5. What else could you have tested in this experiment?  Explain.

6. How does the color of the jacket affect heat absorption?

7. Describe the strengths and weaknesses of the computer model you used in the experiment.  How could you go about conducting this experiment with your jackets?

8.       8. What evidence can you find that suggests darker materials absorb more thermal energy than lighter materials?

  

Conclusion

What was your problem?

Restate your hypothesis.  Was your hypothesis right or wrong?  What facts would support this?

What did you learn in this lab?

What did you like about this lab?

What were some challenges you had to deal with?

What could you do next with this problem?  What other tests could you perform?

Write down any other additional thoughts, observations, inferences, etc.

Lab #9 – The Cell and its Organelles

Problem

How are plant cells and animal cells both similar and different?

Hypothesis

 Materials

I will supply: 2 zip-loc bags: inner bag = cell membrane
1 loose plastic bag: outer bag = cell wall

     Oil (cytoplasm)

     red beans, red and black beads (organelles)
     green beads (chloroplasts)
     clay or balloon (nucleus)

     water (vacuole)
Please bring: uncooked pasta, candy, uncooked rice, get creative! 

Procedure 

Step 1

Pour vegetable oil into one of your Ziploc bags until it’s about half full. The vegetable oil represents the cell’s cytoplasm.

Step 2

Add a piece of cauliflower to the bag. This will be your nucleus.

Step 3

Place three or four mandarin oranges as mitochondria and three or four green grapes as chloroplasts in the bag.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 4

Pour water into a balloon until it is two or three times the size of your nucleus bouncy ball. Tie the end of the balloon and place it in the Ziploc. This will serve as the vacuole, a fluid-filled space within the cell.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 5

Add several pieces of pipe cleaner as endoplasmic reticulum.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 6

Add a piece of ribbon candy to represent the Golgi apparatus and a small marble for the centrosome.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 7

Sprinkle in a small handful of sesame seeds. These will represent the cell’s ribosomes.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 8

Add more vegetable oil to the bag, if needed, until it is fairly full but still has plenty of give. Close the bag.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 9

Maneuver the organelles so they are spread throughout the bag. Make sure your centrisome and Golgi apparatus end up near the nucleus, as this is how they’re situated in a real cell.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 10

Place the bag inside your second Ziploc bag. If it doesn’t fit easily, pour out oil until it does.

Robinson Cartagena Lopez - RoCarLo/Demand Media

Step 11

Drizzle a little bit of oil in the space between the two bags. This represents the cell membrane, a thin, semi-permeable membrane between the cell wall and the rest of the cell. Close up the second bag.

Don’t forget to label your Ziploc bags (Cell Membrane) for BOTH plant and animal cells.

Results

Animal Cell	Plant Cell

Analysis

1. Compare/Contrast your plant and animal cells.

2. Predict what would happen to a plant cell if it were to lose its chloroplasts.

3. Explain the importance of the nucleus in both cells.

4.       On your gel cells, what is representing the cell membrane?  How is the cell membrane like your skin?

_____________________________________________

5.       Create your own model of an animal and/or a plant cell.  What materials would you use?  Make a list of what is going to represent the following: cytoplasm, cell membrane, nucleus, organelles, cell wall, chloroplasts.
