2. Cut it into 3 cubes measuring 3cmX3cmX3cm, 2cmX2cmX2cm, and 1cmX1cmX1cm.

3. Place the cubes in your beaker and just cover with the solution. Make sure they stay submerged.

4. Let the cubes sit for 10 minutes.

5. While the cubes are soaking fill in the table below under surface area. Calculate surface area by finding the area of one side and then multiplying by the total number of sides. Use the formula: SA = l x w x # sides. Remember a cube has 6 sides.

Surface area 1x1x1=6 sq. cm. 2x2x2=24 sq. cm. 3x3x3=54 sq. cm.

Example: 5 cm cube SA = 5cm x 5cm x 6 SA = 150 sq cm

6. Calculate the volumes and complete that portion of the table. Show your work. To find a cube's volume, use L x W x H. Example: 5 cm cube V = l x w x h V = 5cm x 5cm x 5cm V = 125 cubic cm Volume 1x1x1=1 cubic cm. 2x2x2=8 cubic cm. 3x3x3=27 cubic cm.

7. Find the surface area to volume ratio and complete the correct column of the table. Divide surface area by volume and reduce to the lowest fraction. Show your work. Use only the number values when calculating. Example: 5cm cube SA/V = 150/125 SA/V = 1.2

Surface to volume 1x1x1=.166666 2x2x2=.3333333 3x3x3=.5

8. Remove the cubes after 10 minutes and carefully cut them in half.

9. Measure the amount of diffusion in centimeters and record it in the table (Diffusion depth.) .5cm

10. Calculate the rate of diffusion and record in the table. This is calculated by dividing the amount of diffusion by the time (10 minutes). Show your work. Use this formula: R = d/t R=rate of diffusion d=distance the material diffused in cm t=time .5/10 = .05 ( the rate is 5/10cm. per minute

Three interesting facts

2.These plants can escape into the wild and some variants are considered an invasive species. 3. They provide a useful habitat for small fish and crustaceans, but because they propagate by breaking off and floating away, they can often choke up a pond.

Three interesting facts 1.It is osmosis & diffusion.

In plain water, cells take up water, swell & look larger and pale. 2.In saline water (if hypertonic=high concentration), cell will leave water 6 shrink and look dense. In normal saline (0.9% NaCl), cell usually remain as their original size. = Bio molecules in food results =

On your team page, complete the following:


 * 1) Provide the results from the four different foods you tested by making a data table. Make sure to include the results of all 4 tests (simple sugar, starch, fat, protein) for each food
 * 2) In a paragraph, discuss biomolecule(s) that are found in all 4 of your foods. Which of the biomolecules surprised you by their presence or absence in the various foods you tested? Biomolecules that where found in all of the four foods that showed up positive was Simple sugars that surprised the whole group. Fats and oils surprised us also because the results where better than we expected. Back to the simple sugars it was pretty cool how all of the results showed up positive but what got us why these foods were all positive. One biomolecule that got our attention is Starches because starches are usually in potatoes and we didn't except in to be in Gatorade. Finally, we thought that the whole lab went pretty good overall
 * 3) Look at the data collected from other classes. Were there any differences in the results that you obtained compared to others that tested the same foods?What are some reasons why your results were different than others who tested the same food? Some groups found that there was no starch in Gatorade, while we found that there was. We also found that there were fats and oils in Apples, while other groups found that there wasn't. The difference could be the aging of the foods over periods or that the person researching the foods could misinterpreted information in one of the groups.

flat To get the maximum amount of ATP you must have the light intensity at 200 Lux and the wavelength at 425nm

Van Helmont- He conducted an experiment where he tried to show the trees take nutrients from the ground. He thought most of the mass of the plant was the water that was taken in. Priestley- In 1772 he had evidence that gases participate in photosynthesis. He knew that if a burning candle is placed in a sealed chamber, the candle will soon go out. He also knew that if a rat was placed in a sealed chamber it would die. He stated it was simply the growth of the plant that accounted for this. Ingenhousz-He discovered in 1778 that the effect observed by priestley occurred only when the plant was illuminated. A plant kept in the dark in a sealed chamber consumes oxygen just as a mouse or candle does. He also demonstrated that only green parts of the plants liberated oxygen during photosynthesis. Calvin- He discovered the dark reaction, the 2nd part of photosynthesis. This stage does not require light to occur and during which energy released from ATP drives the production of organic molecules from carbon dioxide. Came up with dark reaction.

DNA Questions
 * 1) The five elements that make up DNA are: Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen.
 * 2) The day to day function of DNA is to control the bodies cells and contain genetic information.
 * 3) Strands of DNA can fit into a cheek cell because they bundle up into chromosomes
 * 4) The reason why we used detergent as a lysis solution is that detergent can break down cells to make them more visible.
 * 5) Alcohol makes DNA visible because alcohol is positive while DNA is negative.
 * 6) We are able to see the DNA because the positive alcohol makes the negative DNA clump together.
 * 7) DNA is referred to as your genetic fingerprint because no one strand of DNA is alike.
 * 8) DNA is used everyday to: find criminals using DNA as evidence, in hospitals to identify patients, and to tell the body how to function.[[image:Photo on 2-10-14 at 8.46 AM.jpg width="235" height="157"]]
