ReviewReview

A zoologist questioned the ability of baby cubs raised in a zoo to survive in a wild environment. She believed the cubs raised in captivity had lost their fear of predators. To test her idea, she placed 15 captivated young cubs and 15 wild young cubs of the same age into separate but identical cages. She then placed a clear piece of Plexiglas in each cage. In each cage, she placed the cub on one side of the Plexiglas and a large predator, a mountain lion, on the other side of the Plexiglas. She then recorded the amount of time it took the young cub to move to the back of the cage and away from the mountain lion. She found that the captivated cubs from the zoo were much slower in moving away. This led her to believe the caged cubs have less fear of predators than do wild cubs.

SCENARIOSCENARIO

Today, we are going to conduct a scientific investigation.

We will use the SCIENTIFIC METHOD!

Page 7: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

SCIENTIFIC METHODSCIENTIFIC METHODThese are the first few steps of what

we called the SCIENTIFIC METHOD.

Every time a scientist explores the world, they follow these six steps:

1. Ask a question!2. Make a hypothesis.

3. Research your hypothesis.4. Design an experiment.

5. Analyze your experiment.6. Reach a conclusion.

Page 8: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 1 | ASK A QUSTION

Question: How will different types of music affect your heart rate?

Page 9: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 2 | DEVELOP A TESTABLE HYPOTHESIS THAT ANSWERS THE QUSTION

Research:

•What is your opinion of rap music?

•How does rap music make you feel?

•What is your opinion of rock n roll

music?

•How does rock n roll music make you

feel?

•What is your opinion of classical music?

•How does classical music make you feel?

Page 10: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 3 | DEVELOP A TESTABLE HYPOTHESIS THAT ANSWERS THE QUSTION

Research:

•I think that rap music will _________________my heart

rate

•I think that rock n roll music will ____________my

heart rate.

•I think that classical music will _____________my heart

rate.

•Now, choose a type of music and form an hypothesis

using “if” and “then”

STEP 4 | DESIGN AND CONDUCT AN EXPERIMENT

Procedures:•Find your pulse on your neck

Every time you feel a thump = 1

Page 13: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

Procedures:•Count your resting heart rate for 30 seconds and then

record it in the table. Repeat.

•Listen to Rap music for 1 minute

•Count your heart rate for 30 seconds and then

record it in the table.

•Repeat

•Listen to rock n roll music for 1 minute

•Count your heart rate for 30 seconds and then

record it in the table.

•Repeat

•Listen to classical music for 1 minute

•Count your heart rate for 30 seconds and then

record it in the table.

•Repeat

Average

Heart Rate (Trial 1)

After Rap Music

After Classical Music

After Rock n Roll Music

STEP 5 | ANALYZE DATA Average = (Trial 1 + Trial

2) / 2

•Why do you think it is important to do two

trials?

STEP 6 | REACH A CONCLUSION

•A conclusion is similar to an inference. We

must use our data to decide what happened.

•Ex: You have an I-pod. One day you turn

your I-pod on, but it doesn’t work. You think

the I-pod is dead, so you charge it. But your I-

pod still will not work! You replace the

headphones, and now your I-pod works.

•You can conclude that the headphones

are broken.

STEP 6 | REACH A CONCLUSION

•In science, drawing a conclusion

means summing up what you have

learned in your experiment.

•Ex: Czar hypothesized if the day is

sunny, then the hottest time of day will

be about 3 o’clock in the afternoon.

Page 18: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 6 | REACH A CONCLUSION

•Czar conducted an experiment, and got the

following data.

10 am

11 am

12 pm

1 pm

2 pm

3 pm 4 pm 5 pm

Temperature

20 26 31 33 34 35 31 29

When was the hottest part of the day?What can Czar conclude?

On sunny days in July, the warmest temperatures occur about 3 pm.

Was Czar’s hypothesis supported or rejected?

Page 19: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 6 | REACH A CONCLUSION

•How did rock and roll music affect your heart

rate?

•How did rap music affect your heart rate?

•How did R & B affect your heart rate?

• Does this conclusion support or reject your

hypothesis?

Page 20: Warm Up 1.Write a detailed procedure on how to make a peanut butter and jelly sandwich. The following materials are available to you to make your sandwich:

STEP 6 | REACH A CONCLUSION

•Was your hypothesis confirmed?

•What data supported your conclusion?

•What errors did you make during the lab?

• What are your plans for future experiments

that answer the same question? What would

you do differently?

• Why is it important to communicate your

findings clearly in a good conclusion?
