Elodea Lab

1st step of the scientific method?

• Ask a question & do research
• Observe your environment
• Make a hypothesis (1st claim)
• Perform an experiment to test your 1st claim

What observations did we make?

• Elodea's are autotrophs
• Elodea's make food (glucose) through photosynthesis
• How are elodea's effected by the distance from the light source?
• All choices

During step 1: observing our environment we do which?

• look at the environment around us

• Ask questions based on our observations

• Make a hypothesis

2nd step of the scientific method?

• Ask a question & do research
• Observe your environment
• Make a hypothesis (1st claim)
• Perform an experiment to test your 1st claim

What question did we have in our experiment?

• How is the amount of bubbles of oxygen released by the elodea effected by the distance to the light
• How does the brightness of the light effect the growth of the elodea?
• How is size of the elodea effected by the distance to the light
• All choices

Scientific questions are

• Factual & Testable with an experiment
• Factual
• Opinions
• Factual & answered by researching in books

Research can be done by...

• Watching videos about concepts surrounding the question
• Reading about the scientific concepts surrounding the question
• Learning in class about the science concepts surrounding the question
• All choices
