PURPOSE
- What is the purpose of your lab?
- What is your goal?
- What are you trying to determine?

Hypothesis:
a statement based on an observation or previous knowledge that allows for the design of an experiment to test it.

HYPOTHESIS CRITERIA
- NOT a question
- NO "I" or "I wonder"
- Is a specific statement
- Can be experimentally tested
- Contains only ONE variable

A HYPOTHESIS IS...
- NOT a question, but a statement that includes your prediction
- Can be true or not.
- You do NOT have to be correct, it is your best guess as to what you think is correct

WHAT IS A VARIABLE?
- Experimental variable: the factor or thing you are changing to see if it is the cause

WHAT IS A VARIABLE?
- Control variable: what you are keeping the same throughout the experiment

MATERIALS
- List ALL of the materials you will use
- Think about this like the ingredient list to a cooking recipe

METHODS
- Step-by-step instructions
- Number each step (like a recipe)
- Should be so specific that someone else could replicate it!

Lab essentials, purpose, hypothesis, materials and methods should all be done BEFORE the experiment has begun

This is important.
These steps will help you understand:
(1) what will happen in the experiment
(2) possibly help you understand your results

OBSERVATIONS
- Information gathered before and after experiment is started
- May take form of notes, charts, sketches, or data

Up until here, your information may be similar to your lab partner's but NOT copied or printed out for one another.

Remember,
Each student is responsible for understanding the experiment and the results!

CONCLUSION
- Written as a small paragraph in complete sentences
- Here you answer the purpose

PARTS OF A LAB CONCLUSION
- Was your hypothesis correct?
- What were your results? Explain them.
- Was anything surprising?
- Where may there have been human error?

PARTS OF A LAB CONCLUSION II
- How could we improve this experiment?
- What future experiment could we do to build on our knowledge?
- What is the take-away lesson from this lab?
