Renewable Energy Sources
Renewable energy sources come from this.
What is nature?
Before performing an experiment, a scientist must first make this using an "If...then..." statement.
What is a prediction (hypothesis)?
This type of energy is present in all moving objects.
What is energy of motion (mechanical energy)?
This type of energy helps keep us and other things warm.
What is heat (thermal) energy?
Solar panels are used to generate energy from this renewable source.
What is the sun?
Scientist cannot base their evidence on this because it is not factual.
What is a personal opinion?
Amonii observed the American flag moving outside. She stated that this kind of energy is being transferred to the flag, causing it to move.
What is wind?
Sound is produced by this and travels in waves.
What is vibrations?
This is data collected in an investigation.
What is evidence?
Lisa is camping in the winter and sits by her campfire to keep warm using this type of energy.
What is heat (thermal) energy?
Aiden is hungry and wants to toast some waffles in the toaster. The toaster is connected to a wall outlet. In order for Aiden to toast his waffles, he must use this source of energy.
What is electrical energy?
A geyser is an example of this kind of renewable energy source.
Why is it important to record and organize scientific data?
So scientist never have to memorize their data, observations, or procedures. They also do this to keep track of their data so they can replicate the experiment if necessary.
These are the 5 basic forms of energy.
What are light, heat (thermal), electrical, motion (mechanical), and sound?
Solar powered cars are being talked about for the future to reduce waste. Solar panels would be built into the car to make it move. What energy would power the solar car to move?
What is the Sun's light energy?
These are the 4 types of renewable energy sources.
What are wind, water (hydro), sun (solar), and geothermal?
During science class, Dr. Stephens walks in. He does not say anything, but is covered in water and holding an umbrella. Miss. Bookout thinks to herself that it must be raining outside. She used this scientific skill to determine that statement.
What is an inference?
Cayden plucked a rubber band to make a sound. He wants the rubber band to have a lower pitch. He will need to stretch the band like this to make the sound have a low pitch.
*Think back to your rubber band device experiment!*
What is stretch the rubber band shorter?
A microwave has these energies present.
Electrical, heat (thermal), light, motion (mechanical), sound
