Presentation Transcript

Getting started
Getting Started

  • Read through the entire experiment so you will know what is coming up next.

  • Write your hypothesis using the “If-Then” format. Each experiment will have its own hypothesis.

  • Follow the procedure, recording all data. (That means write it all down in an orderly way.)


  • Before you can write the hypothesis, you need to understand the purpose of the experiment. What are you trying to ‘prove’ or find out by doing the experiment? Where do you go for ideas about the purpose of the experiment?

    • What is the title of the experiment?

    • What are the objectives/goals of the experiment?

    • What is in the background information/introductory paragraph that will help you?


  • Procedures can be re-written or copied and pasted into the blank lab report.

  • There are 5 experiments to complete.

  • Experiments #1 – 4 are designed to show a positive test result for each of the biological molecules.

  • Experiment #5 takes different foods and tests them for the presence of each of the biological molecules.

Data observations

  • Complete the table in each experiment.

  • Be sure you have saved all of your information in LNL.

  • Then click on “submit assignment” at the bottom of the first column in student assignments.

Calculations interpretations

  • There are no calculations in this lab.

  • Answer the 3 questions in this section based on the data (information) collected in the 5 experiments.

Finishing up
Finishing Up

  • Use the template to write your report.

  • Type your hypothesis immediately after the directions for it.

  • Type (or copy and paste) your procedure immediately following the directions for it.

  • Insert your data in the space provided in the data section.

  • Answer all of the questions in the calculations/interpretations section.

  • Write your conclusion telling if your hypothesis was correct or incorrect and support your statement with your results. This should be about a paragraph in length.
