A Somewhat Long (or Perhaps Verbose) Example of a Specific and Acceptable Lab Report (and Specifically here, Title)

Introduction

This is where I would like your introduction paragraph. I am expecting at least 5-10 sentences explaining some of the background information. I want you to basically tie this lab in with the material learned in the notes.

Ideas: Definitions of key terms in this chapter (sections 5.6-5.8)

Examples of key terms in this chapter (sections 5.6-5.8)

What were some of the substances tested? What are their respective sizes and/or charges?

Hypothesis

I would like 1-2 sentences explaining the predictionfor each setupwiththe rationale!

Materials and Methods

You can either write a paragraph describing each step, or, if you are more comfortable, then you may simply list the steps. Please make sure the steps are clear and anyone could follow them. Include ALL lab equipment used with appropriate sizes/volumes/masses of reagents.

Data

In this section, you will create two bar graphs.

One will be for the mass of the iodine/starch dialysis tubing before and after the experiment.

One will be a double bar graph: the concentration of glucose for the glucose/water dialysis

tubing before and after the experiment AND the mass of the glucose/water dialysis tubing before and after the experiment.

All graphs must have

-An extremely detailed title that is not the same as the members of your group (and you may not take my title either!)

  • At a minimum, you should include the contents of the dialysis bag, the beaker, and the time frame for each graph

-Labeled category axes for the charts

-Labeled Y-axes for the charts with appropriate units

Analysis—largest points section!

This section is the summary of your experiment. You want to be sure to include the 6 basic ideas below:

-The purpose of the investigation is clearly identified or stated

  • Why was this experiment done? What was tested?

-Conclusion includes whether the findings support or reject the hypothesis

  • Revisit the hypothesis your group generated. What do the data show compared to the hypothesis? Is it supported or rejected? (DO NOT SAY PROVE!)

-Summarizes data used to draw conclusions

  • What evidence specifically supports the rejection or support of the hypothesis? Refer to the data…numbers don’t lie.

-Identifies flaws and possible errors in the investigation

  • What possible errors could have been made by the investigators?
  • Are there any limitations to the experiment? How could it be improved?
  • What could a “next step” experiment be?

-Discusses applications or real world connections.

  • Why does this topic matter? What is the “big picture”? Why is this important to the study of biology/living things?

-Demonstrate comprehensive understanding of the concepts that apply to this investigation

  • Tie this into diffusion, osmosis, the factors that affect these processes, and how those factors affected which material(s) were able to move through the dialysis tubing

NO “I”, “WE”, or “YOU” in the lab report!!!
