Law

Question #12- 2 min

Nadia wants to test which type of Cheetos leaves more Cheetos dust on her fingers. To test this she eats one bag of regular Cheetos, rubs her fingers on a white shirt, washes her hands, eats one bag of Flammin’ Hot Cheetos, and then rubs her hands on the other side of the white shirt. She then measures the size of stain left by each brand on the white shirt.

Identify the independent and dependent variables in this experiment.

Question #12- 2 min

Nadia wants to test which type of Cheetos leaves more Cheetos dust on her fingers. To test this she eats one bag of regular Cheetos, rubs her fingers on a whit shirt, washes her hands, eats one bag of Flammin’ Hot Cheetos, and then rubs her hands on the other side of the white shirt. She then measures the size of stain left by each brand on the white shirt.

Independent variable- Brand of Cheetos

Dependent variable - Size of stain

Question #13- 1 min

Nadia wants to test which type of Cheetos leaves more Cheetos dust on her fingers. To test this she eats one bag of regular Cheetos, rubs her fingers on a whit shirt, washes her hands, eats one bag of Flammin’ Hot Cheetos, and then rubs her hands on the other side of the white shirt. She then measures the size of stain left by each brand on the white shirt.

​

Identify 3 control variables in this experiment

Question #13- 1 min

Nadia wants to test which type of Cheetos leaves more Cheetos dust on her fingers. To test this she eats one bag of regular Cheetos, rubs her fingers on a whit shirt, washes her hands, eats one bag of Flammin’ Hot Cheetos, and then rubs her hands on the other side of the white shirt. She then measures the size of stain left by each brand on the white shirt.

​

Controls- The white shirt, same person testing,

the size of the bag of Cheetos,

the same hand used to each the Cheetos with….

Question #14 – 2min

• Finn wants to test different shoes to see which one is faster. He tries on a pair of Nike shoes and runs a mile. He then puts on a pair of New Balance shoes and runs a mile.

​

Write an acceptable hypothesis for this experiment

Question #14 – 2min

• Finn wants to test different shoes to see which one is faster. He tries on a pair of Nike (sprinting shoes) shoes and runs a mile. He then puts on a pair of New Balance (distance shoes) shoes and runs a mile.

​

If Eileen runs a mile with New Balance shoes on, then she will have a faster time, because Newton shoes are specifically designed for distance running.

Question #15 – 1min

• Finn runs the first mile with Nike Shoes and finishes with a time of 7min and 23 sec. He runs the second mile with the New Balance shoes and finishes in 10min and 45 sec.

​

What conclusion can be made from these results? Are these results reliable?(why or why not)

​

Question #16 – 2min

• Joel notices that the music from his stereo gets quieter when he moves away from the speakers. To test this observation he uses a decibel-meter to measure sound levels at different distances form the speaker.

​

What are two acceptable ways for Elliot to record/ communicate the evidence that he collects in this experiment? (see next slide)

Question #16 – 2min

1. .Record his data in a data table with one column distance, another column sound level

b) Create a graph of the data with distance on the x-axis

and sound level on the y-axis

c) Write a paragraph describing the loudness at specific

positions in his room

d) Draw a picture indicating sound level at the various

distances measured.

​

Which acceptable ways for Joel to record/ communicate the evidence that he collects in this experiment?

​

All of the above are acceptable

17) After Testing your hypothesis you find that your hypothesis is not true. �What does this mean?��

1. Your experiment is a failure

​

• The results are useless

​

• The design of the experiment was bad

​

• The results may be useful, but further testing, redesign of the experiment may be needed.

18) Natural Law is:

a) A set of observations that have been tested time and time again with out any contradictions

​

b) A set of observations that have been tested a few times to be true but sometimes does not have the same results.

​

c) A theory that explains how something occurred but is not observable

​

d) A theory that explains how a law occurs in nature.

19) Learning through Inquiry is important because

1. You always get the right answer

​

​

b) it’s a process of learning by asking questions, collecting evidence and evaluating your hypothesis.

​

c) It allows your hypothesis to immediately become law

​

d) You always have one variable and never have to evaluate your controls.

19) Which scientist is objective?

Dr. Oblach measures everything carefully and writes down his data exactly the way he sees it regardless of his hypothesis

​

​

​

Dr. O fantastic had a hypothesis indicating plants will grow tall with his special light. He rounds all of his measurements up to the nearest inch to ensure his data shows as much growth as possible.

21) What is wrong with this experiment?

Billy is standing on the 10 yard line of the BHS football field and wants to see which football throws the furthest (Nerf or Leather). Peyton Manning is there helping the BHS football team for the day.

​

He throws the Nerf Ball as far as he can

​

Then Peyton Manning throws the leather ball as far as he can.

​

​

There are two variables

How can Billy fix his experiment?

22) Scientific Theories are:

1. Turn into law after five years of becoming a theory
2. Can be tested and proven wrong at anytime.
3. Are observations that are repeatable.
4. Examples are Gravity and Force = M*A

​

23) Inquiry is not:

1. a process of asking questions and conducting experiments

B) a process of proposing explanations to

questions

C) a process of getting the right answer every

time

D) a process of learning through use of the

scientific method

Does everyone feel comfortable with the following:

All of the vocab words on last nights homework

Difference between theory, law, hypothesis and fact

Ability to read an experiment and identify the Independent Variable, Dependent Variable and Controls Variables in an experiment

Independent Variable is the same as Experimental Variable

Control Variable is the same thing as Control

Good Luck on your Quizzam
