Scientific Method Review

Today’s Plan

• Update folders with the DNA Quiz• Review the scientific method• Practice the scientific method in the Tie Dyed

Milk lab• Complete the scientific method homework

DNA Quiz

• Place the quiz in the bindings of your folder.• Fill in the quiz tracker at the front. Put an X in

Midterm Questions Review• We will look at the midterm questions about

the scientific method and go over the correct answers. We are doing this to review the scientific method so you don’t make as many mistakes on the final test in May.

• Get out a piece of notebook paper. Each person at your table needs a piece of paper.

Make your paper look like the one below.Scientific Method Review Name Date Hr

Skip one line between each question and number your page to 14.

1. _________ An educated guess or prediction 2. _________ A list of steps to complete an experiment 3. _________ Words that describe qualities or characteristics 4. _________ Numbers and a label that describe something 5. _________ What is changed in an experiment 6. _________ What is measured in an experiment 7. _________ What is kept the same in an experiment 8. _________ A guess you make after an observation

9. Why is the following hypothesis considered a bad hypothesis? “Plants that are not given fertilizer will grow taller.”

a) It doesn’t have “if” and “then”.b) The prediction is wrong.c) The independent and dependent variables are in the wrong order.d) This is a good hypothesis.

10. De’Lon wants to know if students do better on their homework if they listen to classical music or hip hop music. What is the independent variable in this experiment?

a) Students’ grades on homeworkb) The age of the studentsc) The volume of the musicd) The type of music

11. Which is the example of a qualitative observation?A) It is going to rain later today.B) The clouds are dark gray.C) The temperature is 67 degrees Fahrenheit. D) All of the above.

12. Which is the example of a quantitative observation?

A) It is going to rain later today.B) The clouds are dark gray.C) The temperature is 67 degrees Fahrenheit. D) All of the above.

13. What is the main reason why scientists have constants?

A) So scientists know that their results came only from the independent variable and nothing elseB) So scientists stay safeC) So scientists can record data easierD) So the experiment is clear and easy to understand

14. Identify a constant in this experiment: “Do plants grow faster in the shade?”

A) Amount of shadeB) How fast the plants growC) The amount of water each plant getsD) All of the above are constants

• Make sure your name is on your paper and hand it in to the tray.

• Open your lab book to the “Scientific Method Review Sheet” from last week. If you don’t have this sheet, write on the next blank page of your lab book or on a piece of notebook paper.

• Together we will create an experiment about whether Nikes or Jordans will make you run faster.

Step 1: make an observation and ask a question about it.

What is an observation you could make about shoes if you were in track?-Some people in track wear Nikes and some wear Jordans.What question could you ask about Nikes and Jordans?-Do Nikes or Jordans make you run faster?

Step 1:-Observation: Some people in track wear Nikes and some wear Jordans.-Question: Do Nikes or Jordans make you run faster?

Write this on your paper.

Step 2: Research if needed

What do I already know about this?

What can I do to learn more?

Write this on your paper.

Step 2:-Research: Observe the runners, research online, talk to shoe salesmen, ect

Step 3: Make a hypothesis

Identify your independent variable:-Nikes and JordansIdentify your dependent variable: -speed Write your prediction about which shoe will make you run faster. Remember the If/then format and that what you change goes before what you measure.

Write this on your paper.

Step 3:-IV: Nikes and Jordans-DV: speed-Hypothesis: If you wear Nikes, then you will run faster.

Step 4: Test the hypothesis in an experiment

• How will we test this?• How many times should we test this?• What are some constants we should have?

Write this and finish it on your paper. Make sure you have details explaining exactly what you will do.

Step 4:-These are the steps I will take to test my hypothesis: …-Some constants I will have include:

• Step 5: Record and analyze the data • Step 6: Write a conclusion to sum up the

results

The last two steps of the scientific method would be done if you actually did this lab.

Tie Dyed Milk Lab

• Follow the directions given by your teacher.

Thursday Jan 24 and Friday Jan 25Hand in your Scientific Method HW

Do Now:1. What’s the difference between mass and

weight?2. If something has a mass of 30g, what is its

weight in space?3. Why do some objects sink in water?

Measurement Review

Today’s Plan

• Review measurement together• Complete the length, mass, and volume labs

• Homework tonight!

Write the red info in your lab books

Metric Units

• Kilo, Hecto, Deca, Base (grams, meters, liters), Deci, Ceni, Milli

NOT Metric

• Miles, pounds, inches, feet, ounces

• In science we do not use these units. Science always uses the metric system.

• Metric length smallest to largest:– Millimeter (mm) width of a period– Centimeter (cm) width of your fingernail– Meter (m) width of your table– Kilometer (km) distance between Rogers and the

University

• Meters = length• Grams = mass (the amount of stuff in

something)• Liters = volume (how much space something

takes up)

Other hints:

• When measuring with a ruler, measure starting at the first line (not the edge of the ruler).

• When measuring volume in a graduated cylinder, get at eyelevel with the liquid and read the bottom of the curve.

• Complete the Length, Mass, and Volume labs with a partner. You can have up to 3 people in your group. You must be on task or you risk being separated.

• Hand in your paper if/when you finish and begin your homework. Homework is due on Monday.
