Purpose• Why are you performing the

experiment?• What question would you like

answered?• Phrase question so it is specific and

therefore able to be tested!• Which brand of gum is the best?

– How can we test EVERY brand

of gum?– What is meant by “the best?”

• Which brand of gum, Bubbalicious or Bazooka, blows the biggest bubbles? – Able to be tested and answered

definitively!

“I get it! I can ask: Which flavor of gum lasts longer? Juicy Fruit or Mr. Wonka’s?”

>> 0 >> 1 >> 2 >> 3 >> 4 >>

Hypothesis• Educated Guess• Based on your prior

knowledge and experience, what do you think will happen?

• Example:– I think Bazooka gum

will blow the biggest bubbles because I chew it a lot at home and have blown some huge bubbles with it!

• It is unacceptable not to make a hypothesis or write “I don’t know.”

We hypothesize that we’ll sell more albums this year than last - because, let’s

face it, girls love us!

Materials• List of objects you will use

to perform your experiment

• Be specific enough so that a complete stranger could repeat your experiment if necessary

• Example:– Two packs of gum (one

Bubbalicious and one Bazooka), timer, ruler with measurements in inches.

Materials Needed to Be a Pop Star: recording

contract, makeup artist, hair stylist

Procedure• The exact description and order of the

steps taken to perform the experiment• Again, be so specific that a complete

stranger could understand and repeat the experiment if necessary

• Example:– 1. Unwrap and chew 1 piece of

Bubbalicious bubble gum for 30 seconds (use timer).

– 2. Blow bubble as large as possible.– 3. Using ruler, partner will measure

diameter of bubble to nearest tenth of an inch.

– 4. Repeat steps 1-3 with 1 piece of Bazooka bubble gum.

– 5. Compare diameters of bubbles blown.

1. Practice and hard work.

2. Sign a record label3. Become a country pop

star.4. More practice and

hard work.5. Sell millions of albums

Results• What did you observe?• Be specific; give

measurements if appropriate.

• Be OBJECTIVE – do not draw any conclusions or give your opinion here

• Example:– While Bubbalicious gum can

produce a bubble with a diameter of 3.7 inches, Bazooka gum can produce a bubble with a diameter of 4.2 inches.

The results are in!!!!! The next American Idol is…..

>> 0 >> 1 >> 2 >> 3 >> 4 >>

Conclusion• Explain the

significance of your results

• Answer the purpose question

• Example:– Bazooka blows bigger

bubbles (by 0.5 inches) than Bubbalicious bubble gum.

I conclude that if you study and apply these

terms, you’ll be a master scientist in no time!
