Scientific Method Taboo

Goal: you want your audience to guess the vocabulary word on your card.

Rules: You cannot say any of the words on your card. To guess, students have to raise their hand and wait to be called on. No calling out answers!

Complete IV, DV, and Hypothesis worksheet

Complete only the front side of the worksheet with your tablemates. We will be going over the answers together.

Tuesday Sept 18 or Wednesday Sept 19Do Now: 1. Write 2 observations about what your clothes look and

smell like. 2. Make a guess about what is happening in the picture.

What you did in the Do Now

• When you use the 5 senses, you make observations.

• When you make a guess using your observations, you make an inference.

• Today we will learn about the inferences you can make using observations.

Importance of Observations & Inferences

Why Learn Them? How People Use Them• Understand scientific

method better

• Improve your explanation skills

• Help you solve problems

• Scientists: When doing experiments

• Doctors: When figuring out what’s wrong with a patient

• Detectives: When trying to solve a case

Review Observations

• You make observations using the 5 senses (sight, smell, taste, sound, and touch).

• Qualitative observations are words that describe characteristics. It tells what something is like. (purple writing)

• Quantitative observations are words that describe using numbers and a label. (35 students)

Review Observations

• Observations are like facts. • Everyone can make the same observations.

Review Observations

• Make a qualitative observation about the picture below.

• Make a quantitative observation about the picture below.

Example of Observations

Mrs. Thorsen’s observation:____________________________

Student 1 observation:____________________________

Student 2 observation:____________________________

Inferences

• An inference is a guess you make after an observation

• Inferences are NOT the same for everyone

• Inferences are like opinions: everyone has a different one

Example of Inferences

Mrs. Thorsen’s observation:____________________________

Mrs. Thorsen’s inference (guess): ____________________________

Student observation:____________________________

Student inference (guess):____________________________

Example 2:• My Observation:

• My Inference:

Example 3:

• My O:

• My I:

Difference Between Os & IsWAIT FOR SIGNAL!

During Activity Expectations• Read sentence with your

group.

• Decide together if it is an observation (O) or inference (I)

• Wait for signal to hold up O or I

• WAIT FOR SIGNAL

• Respect all answers

• EVERYONE participates

Difference Between Os & IsWAIT FOR SIGNAL!

• The car is yellow

Difference Between Os & IsWAIT FOR SIGNAL!

• It is dark outside

Difference Between Os & IsWAIT FOR SIGNAL!

• It is night time

Difference Between Os & IsWAIT FOR SIGNAL!

• There is water on the floor

Difference Between Os & IsWAIT FOR SIGNAL!

• Someone spilled water on the floor

Difference Between Os and IsWAIT FOR SIGNAL!

Nicki Minaj is happy.

Difference Between Os and IsWAIT FOR SIGNAL!

Nicki Minaj’s hair is pink.

Glossary Time

• Add the red word to your glossary. Remember to write the page number. You do NOT need to write the definition.

• Inference

On a piece of notebook paper…• Write your name, date, and hour on the top.• Write “Observations and Inferences Pictures”

at the top of your paper.• Number your page 1-16. Skip one line

between numbers.• You will be writing one observation and one

inference for each picture. • You will be handing this in, so make sure to do

all of the work.

Thursday Sept 20 or Friday Sept 21Do Now: 1. An independent variable is what you ______.2. A dependent variable is what you ______.3. Why should a race between 2 people be fair?

Steps of the Scientific Method

Steps of the Scientific Method1. Make an observation and ask a question

about it.2. Research if needed3. Make a hypothesis4. Test the hypothesis in an experiment5. Record and analyze the data6. Write a conclusion to share your results

Why do we research in science?

Brainstorm as many methods of research as you can think of.

• Example: Using the Internet

Procedure Notes

• A procedure is a list of steps to complete an experiment. It is like the directions.

Procedure Notes

• Follow these steps to test a hypothesis:– 1. Gather materials• Include materials to record data, measure the DV, and

safety– 2. Write a procedure• Include details for each step• It should be easy for anyone to follow

Procedure

• Why do we need to have a clear and detailed procedure?

• Procedures should be clear and detailed to increase accuracy and decrease mistakes.

Procedure Drawing

• Get out one piece of paper• Follow the procedures given by your teacher.

Procedure Drawing

• In your lab book, write three things you learned about procedure from the drawing activity.

Constants Notes

• A constant is everything that stays the same in an experiment.

Constant Notes

• Why is it important to have so many constants?

• It is important to have constants so we know what happened in the experiment happened only because of what we changed on purpose.

• Constants make experiments reliable and accurate.

Think about it this way…

• We want to find out who can do the most sit-ups in a minute.

• IV: we are changing the person doing the sit-ups

• DV: we are measuring how many sit-ups they can do

Was that fair?

• Why not?

• WE DIDN’T HAVE ANY CONSTANTS!!!

Constants

• Take this scientific question: Will the amount of sunlight a plant receives affect how tall the plant grows?

• What constants do we need?– Soil type– Fertilizer– Amount of water– Type of plant– Plant being inside or outside

Constants

• Take this scientific question: Do students who graduate high school make more money than students who drop out?

Glossary Time!

• Add these words to your glossary. Remember to write the PAGE NUMBER each word can be found on.

• Procedure• Constant

Observations and Constants

• Complete the worksheet on your own.
