I really need help with my science lab. I was sick when we did the lab on Thursday and Friday was a snowday so I did not get to get the observations off my peers. My teacher has allowed people one more day and I do not understand this Lab at all.

If someone could help me write an introduction or abstract I would be highly greatful.

MEMBRANES LAB
It is a lab based on osmosis (I think?)where we took potato and placed it in different sucrose/water combinations.

This is a gr. 11 Science Biology lab. If someone could help me please post here and I will go in detail or preferably email me at

its the AP Bio lab #1. It wont let me post a website, but google Pearson LabBench and it'll be the first site. it explains it all for you after you get through the dialysis section of the lab

potatoes don't have water potential scott

I'd be happy to help you with your science lab! Let's start by understanding the purpose of the lab and what you need to include in your introduction or abstract.

1. Understand the Lab:
Based on your description, the lab seems to be about osmosis, which is the movement of water across a semi-permeable membrane. In this case, you used different sucrose/water solutions to test osmosis on potatoes.

2. Writing the Introduction or Abstract:
To write an introduction or abstract for your lab, you should include the following components:

a. Background Information: Begin by providing some information about osmosis and its importance in biological systems. You can explain how osmosis allows cells to maintain their internal stability by controlling the movement of water.

b. Objective or Purpose: State the specific objective of your lab. In this case, it could be something like "The objective of this lab was to investigate the effects of different sucrose/water solutions on osmosis in potatoes."

c. Hypothesis: If you have one, state your hypothesis, which is an educated guess about what you expect to observe in the experiment. For example, "It was hypothesized that as the concentration of the sucrose solution increases, the potato will experience greater water loss and decrease in size."

d. Experimental Design: Briefly describe the procedure or methodology used in the lab. Mention the different sucrose/water combinations you tested and how you measured the changes in the potatoes.

e. Expected Results: In this section, you can explain what results you anticipated based on your understanding of osmosis and the hypotheses you formulated. For instance, you might expect potatoes in higher sucrose concentrations to shrink more compared to those in lower concentrations.

f. Significance: End your introduction or abstract by discussing the importance or relevance of the lab. Explain how understanding osmosis and its effects on cells can provide insight into various biological processes.

Remember, it's important to be concise and clear in your writing. Make sure to use proper scientific language and avoid personal pronouns.
