Carey Booth Box Biology 2 February Lab instructor: Ned Knight Lab day: Friday. Sample Formal Lab Report. The following is report that repeats the two classic experiments that were used to disprove Spontaneous Generation--that life originates from non-living substances. Write a formal lab report using the guidelines on the website. The Effect of Mung Bean seed and wheat seed germination when given NaCl. Example IB Biology IA Germination Scribd AP IB Lab Report .
A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement which may include a prediction. When Are Hypotheses Used? The key word is testable. That is, you will perform a test of how two variables might be related.
This is when you are doing a real experiment. You are testing variables. Usually, a hypothesis is based on some previous observation such as noticing that in November many trees undergo colour changes in their leaves and the average daily temperatures are dropping.
Are these two events connected? Any laboratory procedure you follow without a hypothesis is really not an experiment. It is just an exercise or demonstration of what is already known. How Are Hypotheses Written? Salt in soil may affect plant growth. Plant growth may be affected by the color of the light.
Bacterial growth may be affected by temperature. Ultra violet light may cause skin cancer. Temperature may cause leaves to change color. However, their form is not particularly useful. Using the word may does not suggest how you would go about proving it.
If these statements had not been written carefully, they may not have even been hypotheses at all.
One way to prevent making such easy mistakes is to formalize the form of the hypothesis. If the incidence of skin cancer is related to exposure levels of ultraviolet lightthen people with a high exposure to uv light will have a higher frequency of skin cancer.
Refer to AP Biology Lab Manual, investigation 4, for detailed procedure instructions. For part 2 of the experiment, the following was placed in the dialysis tubing: 1. Sucrose inside, water outside. Water was predicted to move into the tubing. 2. Glucose inside, sucrose outside. Water was .

Advanced Placement Program® (AP®). The College Board is committed to the principles of The College Board is committed to the principles of excellence and equity, and that commitment is embodied in all of its programs, services.
If leaf color change is related to temperaturethen exposing plants to low temperatures will result in changes in leaf color. Notice that these statements contain the wordsif and then.
They are necessary in a formalized hypothesis. But not all if-then statements are hypotheses. In a formalized hypothesis, a tentative relationship is stated. For example, if the frequency of winning is related to frequency of buying lottery tickets.
If you always ask yourself that if one thing is related to another, then you should be able to test it.
Formalized hypotheses contain two variables. In the statements above the dependent variable is underlined and the independent variable is underlined and italicized.
The ultimate value of a formalized hypothesis is it forces us to think about what results we should look for in an experiment.
How does the type of liquid water, milk, or orange juice given to a plant affect how tall the plant will grow?
If the plant is given water then the plant will grow the tallest because water helps the plant absorb the nutrients that the plant needs to survive.Formal Lab Write up for AP Biology These will be done for all 12 official AP labs. They must be typed or written neatly (preferably in a lab notebook) or typed (even better!).
Each formal lab write up will count for 2 lab grades and be due – 2 class periods after the lab. Chemistry Lab Resources (for CHM 1XX and 2XX Labs): Writing your lab report/worksheet Here you can find tips about organizing your lab notebook, how to effectively create graphs and table for lab reports, places to locate protocols and property information, and how to properly cite resources.
My lab partners and I placed clamps on both ends of each of the tubes to keep the solutions in their bags and in their rightful place. Two of the dialysis bags contained tap water.
The other three solutions inside the bags were 20% sucrose (at least 10mL), 40% sucrose (at .
