Scientific MethodThe scientific method is the process that scientists follow when doing experiments.
Steps of the Scientific Method1. Question2. Research (Observation)3. Hypothesis (Inference)4. Variable and Controls5. Experiment6. Results (Evidence)7. C.E.R. (Valid Conclusion)VariableThe ONE (1) thing you are testing in an experiment.
Only ONE variable per experiment.
Only thing you change in an experiment.
ControlsThese are all the things that you keep the same in an experiment in order for it to be fair.
You can have many controls.
We keep controls the same so the experiment is fair.Examples.Which type of floor cleaners works the best?
What materials would be the warmest to make gloves from?
Which type of cup would keep hot water warmer longer?
Energize!The types of energy in our worldWhat types of energy do we use to make electricity?CoalPetroleum OilNatural GasSolarWind HydroGeothermal
Types of EnergiesWe can always get these energies. We will never run out.Solar energyWind energyHydro energyGeothermal energy
Once we run out, we can never get these energies back in our lifetime.Petroleum oil energyCoal energyNatural gas energyPropane gas energy Renewable Energies Nonrenewable EnergiesFossil Fuels (nonrenewable energy)takes millions of years to form (make)
animals and plants die and are buried under layers of sedimentary rock
Types of fossil fuels:coalnatural gaspetroleum oilpropane gasWhat is so bad about fossil fuels?Nonrenewable (takes millions of years to make)
Cause massive amounts of pollution
Very expensive to get out of the ground ($ and people wise.miners die)
