What is the step where it tells you how to do the experiment?
Procedure

What is the difference between a controlled variable and a independent variable?
A controlled variable is something in an experiment that doesn't change. A independent variable is something that does change in the experiment.
100
In the lab Penny Water why did all of the stay on the penny?
Surface Tension is when all the molecules stick together.
100
How does photosynthesis work?
Plants absorb sunlight and convert it to energy. This is called radiant energy.
100
What is a generator and gravity?
A generator is something used to convert motion to energy Gravity is force being pulled down from outer-space
200
What would happen if we put a rose in the freezer?
Question
200
What are qualitative observations and quantitive observations?
Quantitive is an observation you measure in some way. Qualitative you can taste, smell, hear, feel, or see.
200
What experiment did we experience copper acetate and what is it?
We saw copper acetate in the penny vinegar lab. Copper acetate is when copper, acid, and oxygen are mixed and causes a chemical reaction that left a greenish substance on the penny.
200
What do revolution and rotation mean?
Revolution: One of the Earth's complete turns around the sun- this takes 365 1/4 days Rotation: the movement the earth makes while spinning
200
What is an aquifer, the atmosphere, and atoms
Atoms are tiny bits of matter that make up everything on earth The atmosphere is a thin layer of gases surrounding the earth An aquifer is an underground store of water

What would happen if we put the rose in the freezer for 2 weeks? What if we used another flower? Would it have a different result?
Next Question
300
What words do you have to have in a conclusion and hypothesis?
Conclusion:When, then, because Hypothesis: It, then, because
300
Explain the coffee filter lab.
In the coffee filter lab we drew a black line on a coffee filter and put it on water. Then we saw the black turn into many different colors. This is called chromatography, it is when many different colored inks make up one color ink.
300
What is the difference between precipitation and condensation?
Condensation is the process of a gas forming a liquid. Precipitation is water falling from the sky (including snow, sleet, rain)
300
What are fossil fuels and what is a reflection? What is a photovoltaic cell?
The radiant energy striking one thing and bouncing of and hitting another. That is reflection Fossil fuels are fuels charged by melting fossils An object that turns radiant energy into electrical energy
400
The rose shriveled up and died because all the oxogen was sucked out of it.
Conclusion
400
What is an inference?
To quess or reason
400
Explain why the solar balloon floated.
The reason is because the heat let in the balloon by the thin plastic and the hot air rose because it was less dense. That is how wind is created.
400
What are herbivores, carnivores, and omnivores?
Herbivores only eat things that come out of the ground. Carnivores only eat meat Omnivores eat both
400
What is the water cycle and water vapor? What is evaporation?
The water cycle is the process of water evaporating and floating into clouds then falling down again. Evaporation is the process of a liquid becoming a gas The gas phase of water

What does QHPOCN stand for?
Question, Hypothesis, Procedure, Observation, Conclusion, Next Question.
500
What is an observation?
Something important noticed in an experiment
500
How does the radiometer work?
The radiometer works when the air molecules on the black vane heat up and bounce of the white vanes causing them to spin.
500
What are renewable energies? How do hydropower, solar energy, and wind power work? What about chemical energy and thermal? Biomass?
Renewable is something you can use that either you can use again, or you won't run out of Thermal energy is when you capture heat and transfer it to energy Chemical energy is using the energy from chemicals when they have a chemical reaction Biomass is when you use wood or animal poo and burn it Solar energy is collecting the heat from the sun's rays using a solar collector Wind power is using the wind turning turbines to energy Hydropower is using the water to turn spooks on a wheel
500
What is an axis, hemisphere, equator, and latitude
An axis is an imaginary line that runs from the north to the South Pole A hemisphere is a section of the earth. they are there to separate the parts of the earth. The equator is an imaginary line that runs across the earth from east to west a line of latitude is east west
