Drops of Water on a Penny lab report instructions

Title: What would you name this report?

Observations: Summarize what we saw in the very beginning when we watched what happened to the water drop when it landed on a flat surface.

Testable Question:

Mr. Saeger has a roll of new pennies. What is a testable question about drops on pennies of different ages?

Hypothesis:

A hypothesis is an answer to the testable question. Don't use personal pronouns. Don't try to explain why you think one type of penny will hold a different number of drops.

Independent Variable:

The independent variable is the thing you changed in the experiment. What was the independent variable?

Dependent Variable:

The dependent variable is what was affected by the independent variable and is usually what you measure. What was the dependent variable?

Variables to Control

Some of the ways you did the lab might have changed the number of drops the penny held. We listed several in your notes. List ten using bullet points

Procedure:

List materials.

Give step-by-step instructions so someone else could do the lab the same way you did.

Bullet points are OK.

There are 5 to 10 steps depending on how you write them.

Results:

	Number of Drops (mean)
Control group Pennies > 13 years
Experimental group New pennies

Conclusion:

This is at least 3 complete sentences.

1.     What do the results show about how many drops fit on old and new pennies.

2.    Restate your hypothesis.

3.    Was your hypothesis right or wrong?

4.   Did you think of any other factors that might have affected your results while doing the experiment?

 

 

 Use complete sentences in all sections unless there are directions telling you bullet points are OK. All writing conventions count.

 

 

How to Write a Lab Report Update - Tilt Lab version

Here’s what goes in the Tilt lab lab report.

Title;   
A very brief description of what the lab is about.

Testable Question: 
A question that can be investigated with an experiment. This was done for you on the lab form.

Hypothesis:
A prediction of how the test you are doing will turn out. It is an answer to the question you are testing. Complete sentence. No personnel pronouns. It is not a question. Do not say why or use the word 'because.'

Independent Variable:
The one thing you change in the experiment to see what kind of difference it makes.

Dependent Variable:
The thing that is affected by the changes in the independent variable. It’s what you measure.

Controlled Variables:
The factors you keep the same because they might affect the outcome of the experiment.

Procedure:
Include materials here: A list of everything you used to do the experiment. Do not include everyday items like pencil and paper. Bullet points.
Describe how to do the experiment so someone else could read it and do the exact same thing. Bullet points. It should have at least 6 or as many as 15 steps.

Results:
For this lab its the table and graph. Every table and graph needs a title, each number needs a label, each axis on the graph needs a label, and include a legend for each line on the graph.

Conclusion:
This is where you decide if the independent variable made a difference in the experimental group. Look at the lines on the graph. If the slopes are different, the independent variable made a difference. Use the results to support your conclusion about the independent variable.
 State if the hypothesis was right or wrong.
 If necessary, mention how other factors may have influenced your results. Complete sentences.

Grading comments:

• 30 of the 50 points will be over how well you followed the instructions above.
• Writing conventions (spelling, punctuation, grammar) will be worth 10 points.
• 'Voice,' or how much it looks and sounds like a scientist will be worth 10 points.

Life Science CRT

The Life Science CRT will be on Friday, February 22. We will review in class on Wednesday and Thursday. Students should study all Life Science notes (Cells, Genetics, Interactions of Living Things, and Evolution) and old unit tests. There are vocabulary reviews on Quizlet. Use the links to the right to find them.
