Practical 'sense of touch'

Together with a classmate you are going to perform the practical 'sense of touch'. You will make a lab report about this practical.

Do you know how to write a lab report?

No? Watch the following:

Are you writing a lab report for biology, physics or chemistry? Then you are writing a scientific paper. A real scientific paper includes the following: Introduction Start with the explanation about why you are doing the experiment. Include the things you already know and the theories you have already learned. Research question Write down the question you are trying to answer with the experiment. This is your research question. Explain what you are investigating and how you are going to get an answer to your research question. Material Write down the materials somebody would need if they wanted to do the same experiment. If the setup is quite complicated you should also make a drawing of how everything is put together. Method In your own words, explain how you perform the experiment. Keep in mind, somebody else must be able to re-do the experiment by reading your lab report! Results Write down what you observed during the experiment. Everything you: saw, heard, smelled, measured, counted, etc. In the results there should be either a drawing, a graph or a table (sometimes multiple). If you needed to calculate something show your calculations in the results. Conclusion In the conclusion you answer the research question. Answer the question in a full sentence. Make sure the conclusion matches the results. Discussion In the discussion you explain why the results lead to your conclusion. Also you give tips on how to improve the experiment. This way somebody who reads your research can make an even better experiment! Are you finished? When you are finished make sure your lab report includes the following: a title the subject your first and last name your class the date if there are multiple pages, include a contents page If you have used information from a book or the internet, make sure to mention which sources you used at the end.

Now we remember how to write a lab report we can move on with the following:

- Download the handout: Practical skin senses
- Read the handout
- Get all the materials ready at your station (so you won't have to walk during the experiment)
- Execute the practical as instructed
- Make a lab report about the experiment
- Dont forget to fill in the evaluation
- Before handing in your work, take a look at it and think about how you would grade your work
- Hand in the lab report to your teacher

Good luck!
