Observations and Inferences
When I say "I see...", this is an example of a _____________.
OBSERVATION
What is the first step of the scientific method?
ASK A QUESTION
Does GASOLINE have energy? Why or why not?
YES, gasoline has energy. It has the ABILITY TO MAKE THINGS MOVE OR CHANGE.
OR
YES, gasoline has energy. It has POTENTIAL ENERGY, which is STORED ENERGY.
This connects evidence to the claim.
REASONING
Choose if the following is a RENEWABLE or NON-RENEWABLE source of energy and explain why:
HYDROELECTRIC POWER PLANT
RENEWABLE: There is unlimited water, and it can be used again.
When I say "I think...", this is an example of a ___________.
INFERENCE
After we "Test With An Experiment", the next step of the scientific method is ________________.
ANALYZE RESULTS AND DRAW CONCLUSIONS
What kind of energy does a BATTERY have? How do you know?
A BATTERY has POTENTIAL ENERGY, because:
- it has STORED energy
- we can not see the evidence of the energy but it has the ability to make things move or change
The observations we use are considered ______________ to prove or dispute a claim.
EVIDENCE
What is one major benefit to both SOLAR ENERGY or WIND ENERGY?
BONUS FOR DOUBLE POINTS: Why are these energy sources not the most ideal for the rescue workers during emergency situations?
They are RENEWABLE sources of energy.
BONUS:
Each depends on specific weather conditions. For example, the rescue team may not have access to sunlight.
Is the following statement an OBSERVATION or INFERENCE?
"If I touch the pot handle, I will burn my hand"
BONUS FOR DOUBLE POINTS: Is this QUALITATIVE or QUANTITATIVE information?
INFERENCE
BONUS: QUALITATIVE
For Experiment 2: How does exposure to sunlight affect plant growth?
Based on my research, I believe that more exposure to sunlight will help plants grow taller. I have not tested this with an experiment yet. What step of the Scientific Method is this?
________________________________
CONSTRUCT A HYPOTHESIS
What kind of energy does light from the sun have?
Kinetic or Potential?
Neither. It has LIGHT ENERGY.
Which claim is true?
CLAIM 1: Objects can make their own energy
CLAIM 2: Objects get energy from other objects that have energy
CLAIM 2: Objects get energy from other objects that have energy
Why is a NUCLEAR POWER PLANT considered a NON-RENEWABLE energy source?
It depends on Uranium. There is only a limited amout of uranium on Earth, and it can not be used again once used.
Is the following statement an OBSERVATION or INFERENCE?
"When I rang the doorbell, no one answered"
BONUS FOR DOUBLE POINTS: Is this QUALITATIVE or QUANTITATIVE information?
OBSERVATION
BONUS: QUALITATIVE
A 6th grade class was sampled to see how many of each type of fingerprint there was. For the class, the totals were:
ARCH: 30
WHORL: 60
LOOP: 110
As a percentage, this was:
ARCH: 15%
WHORL: 30%
LOOP: 55%
Which type of fingerprint was the LEAST COMMON? Use the data to support your claim.
Arch was the least common. Arch only accounted for 15% of the class OR 30 out of 20 fingers sampled.
ROCK ROLLING DOWN A HILL
Does it have Kinetic Energy or Potential Energy?
Why?
Kinetic Energy.
It is MOVING. Kinetic energy is the energy objects have when they are moving.
Use the energy system described below to provide one piece of evidence to support the following claim:
CLAIM: Objects get energy from other objects that have energy.
Energy System:
SUN -> SOLAR PANEL -> LED LIGHT
EVIDENCE:
Each object received it energy from another object.
The LED LIGHT received it from the SOLAR PANEL.
The SOLAR PANEL received it from the SUN.
From the options listed below- What would be considered the WORST energy source for the rescue workers? Why?
NUCLEAR POWER PLANT
FUEL BURNING POWER PLANT
WIND TURBINES
HYDROELECTRIC POWER PLANT
HAND CRANK GENERATOR
COMBUSTION ENGINE
SOLAR PANEL
NUCLEAR POWER PLANT (or fuel burning power plant)
- the size, not portable
- non-renewable
Will also accept any answer where the size does not allow it to be portable.
Is the following statement an OBSERVATION or INFERENCE?
"Corn must be her favorite vegetable, because she ate a lot"
BONUS FOR DOUBLE POINTS: Is this QUALITATIVE or QUANTITATIVE information?
INFERENCE
BONUS: QUALITATIVE
For Experiment 2: How does exposure to sunlight affect plant growth?
I will let 3 plants grow for 4 weeks, 1 in direct sunlight, 1 in a shadow, and the other with no sunlight. I will then measure the plant growth at the end of the 4 weeks.
What step of the Scientific Method is this?
TEST WITH AN EXPERIMENT
Mr. Barone is stretching out a rubber band over his fingers and aiming at students talking over him.
Explain when the rubber band would have potential energy.
Explain when the rubber band would have kinetic energy.
Use FULL SENTENCES.
The rubber band would have potential energy when it is stretched and not moving.
The rubber band would have kinetic energy when it is moving through the air.
Provide the REASONING to connect the following evidence and claim:
EVIDENCE: The fan moved when it was connected to the battery.
CLAIM: Objects get energy from other objects that have energy.
BONUS: Was the energy converted or transferred in the battery/fan system?
The fan got its energy from the battery. Energy is the ability to make things move or change. The battery made the fan move.
BONUS:
Energy was transferred from the battery to the fan.
Energy was also converted from potential energy in the battery to electrical energy, to kinetic energy in the fan.
From the options listed below- What would be considered the BEST energy source for the rescue workers? Why?
NUCLEAR POWER PLANT
FUEL BURNING POWER PLANT
WIND TURBINES
HYDROELECTRIC POWER PLANT
HAND CRANK GENERATOR
COMBUSTION ENGINE
SOLAR PANEL
BONUS FOR DOUBLE POINTS: Describe the full system needed to power a flashlight using the energy source.
HAND CRANK GENERATOR because it is:
- portable
- renewable
- works under all conditions
BONUS:
- hand crank generator
- battery
- flashlight
