Sample Simple Lab Write-Up

Testing Dish Washing Detergents

(Leave out personal pronouns like I, we and leave out ‘think’. Use these in the conclusion only.)

Purpose

To determine which dish detergent will make more suds.

  Hypothesis

Suds A Lot will make more suds.

  Procedure

4 detergents will be tested, (list them)

3 cups of water and 1 teaspoon of detergent will be put into a one liter bottle.

The bottle will be shaken for 1 minute.

The height of the suds will be measured in centimeters.

Results

Try to table your results.

D

Conclusion

The results have shown that Suds A Lot performed poorly in these tests. Clean All had far more suds at 16cm than the other detergents. Suds A Lot only had 6 cm. CleanClean had 10 cm and Dishes Done had 11cm.

I question whether or not this has anything to do with how well these detergents clean. But if I had to choose a detergent, based on the tests, I would choose Clean All.
