Scientific method intro (Part B)Mr. LambertIntegrated Science 1ATrimester 1, 2014

+Bell Ringer

How do you think scientists do their work? What do you think they are looking for? Patterns? Relationships? As a scientist do you think it is important for other scientists to agree with your work? Why or why not?

+Agenda

1. Bell Ringer2. Reading review3. Systems4. Kinetic & potential5. Exit Slip

+Learning Targets

On your Bell Ringer Sheet, write the following:

We will make observations, and form hypothesis.

+Scientific Method

1. Ask a Question2. Make a Hypothesis3. Design an Experiment4. Analyze Data5. Draw Conclusions

+ 1. ObservationLooking at something very closely

Example: Hmmm….fish in small bowls are small, but fish in big bowls are big.

Look for patterns!

+Test your observation skills

From your seat: pick any object in the room and observe it!

Describe it in as much detail as possible, but don’t give the name or any identifying clues.

Lets see if we can figure out what you described!

+2. Ask a questionWhat are you curious about?

Example: Why are fish in fishbowls small, but fish in fish tanks big?

+20 Questions

Each group gets one question. Can you guess what I’m thinking of?

+3. Form a hypothesis

A prediction that can be tested using the scientific methodExample: Fish in large environments will grow to be

larger in size.

+3. Form a hypothesis

Key points:1. Can be TESTED2. Is state as FACT, not feeling or thought or

belief

+ Hypothesis or not???With your group, decide which of these are hypotheses and which are not!

1. Drummers are all clueless.2. If you have two drummers in the same band, that

band is doomed!3. The instrument with the highest pitch is the guitar.4. Tighter drum heads make a higher pitch.5. I think drummers have higher IQ than guitarists.6. If a drummer uses more high hat, then the song

will sound better.

+Flashlight Lab

In your groups: create a test-able hypothesis as to why my flashlights don’t work!

+Experiment

A scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.Example: I place one goldfish in a small bowl and one

goldfish in a big tank. After three months, I compare their sizes.

Good experiments have several components!

+Parts of an Experiment

Independent Variable:What you’re changing directly

Dependent Variable: What you’re observing/measuring

Control:What you have to keep the same

+Flashlight LabIn your groups: create an experiment that you could use to test your hypothesis. Remember, you need to think about:

1. What will you change?2. What do you think you will observe?3. What will you have to keep the same?

+Analyze results and draw conclusions

I compared the size of my two fish after 3 months and the fish in the large tank was bigger! My hypothesis was correct!

Hypothesis wrong = NEW HYPOTHESISHypothesis right = SHARE RESULTS!

+Flashlight Lab

Test it!Record your observations, then make a NEW hypothesis.

Only change/fix one thing at a time!

+Exit Slip

What must you do before you can make a hypothesis?

What is a hypothesis?What is the next step after making a hypothesis?
