What does energy have the ability to do? (2 things)
What is Do work and cause change
100
What's the difference between a renewable resource and a non-renewable source of energy?
What is renewable sources can be replenished in our lifetime and will not runout. Non-renewable resources will eventually run out. They are not able to be replenished in our lifetime.
100
Give an example of a physical change.
What is answers will vary.
100
What is the difference between a rock and a mineral?
What is minerals have a definite chemical composition. Rocks are a mixture of minerals.
100
Where does the independent variable go on a graph?
What is on the x axis.
200
List 5 types of energy (not kinetic or potential)
What is sound, thermal, radiant, chemical, mechanical, electrical, nuclear
200
Where does the chemical energy from food originally come from?
What is the sun.
200
What is a chemical change? Give two "proofs" and an example.
What is Two or more substances react together to make something new. color change, bubbling, precipitate is formed, energy is released, a new substance is produced. baking, rusting, rotting, digestion
200
What is Moh's hardness scale. How is it used to identify a mineral?
What is rating scale from 1-10. 1 is the softest, 10 is the hardest mineral. Explain the scratch test.
200
What are the 5 steps of the scientific method?
What is ask a question, form a hypothesis, test, analyze data, draw a conclusion
300
What is the difference between kinetic energy and Potential energy? Give an example of each.
What is kinetic is energy in motion (a moving car). Potential is stored energy (a rock sitting on the desk)
300
where do fossil fuels come from? Give two examples.
What is fossil fuels come from plants. They are found deep underground. Oil, natural gas, and coal are examples.
300
What is the difference between a reactant and a product?
What is reactants are what you start with in a chemical reaction, and products are what you end with.
300
What is the difference between and intrusive igneous rock and an extrusive igneous rock?
What is intrusive rocks are found within the ground cooling slowly and have big crystals. Extrusive rocks cool quickly above ground and have small crystals.
300
Give an example of bias during an experiment.
What is changing results to make your hypothesis be correct.
400
Describe the motion of a pendulum in terms of kinetic and Potential energy. Where is the potential energy the greatest? Where is the kinetic energy the greatest.
What is as the pendulum swings it decreases potential energy and increases kinetic energy. At the bottom of the swing the kinetic energy is the greatest and the pendulum is swinging the fastest. As it swings up, it is increases potential and decreasing kinetic. The potential energy is the greatest at the top of the swing.
400
Choose a source of energy. Give to positives about this source and two negatives.
What is answers will very
400
5 grams of zinc is combined with an amount of HCl in a closed container. The mass of the final products is 11 grams. What was the mass of the starting HCl and why?
What is 6 grams- The Law of Conservation of Mass says you can not created or destroy matter, therefore the mass of the starting reactants and the mass of the ending products must be the same.
400
What is the five part definition of a mineral?
What is a naturally formed, inorganic solid with a crystalline structure and a definite chemical composition.
400
How is a plant cell different from an animal cell?
What is plant cells have a cell wall and chloroplasts that hold the chlorophyll
500
Explain the Law of conservation of energy and why a pendulum eventually slows to a stop.
What is the law of conservation of energy states that energy can not be created or destroyed, just transferred to a different form. A pendulum slows down not because it is losing energy, but because the energy is being transferred to heat energy because of friction with the air.
500
How is coal used to created energy? Explain the energy transfer.
What is coal burned to heat water to make steam which turns the blades of a turbine which is used to move a magnet through copper coils producing electricity. chemical energy to heat energy to mechanical energy to electrical energy.
500
Draw a picture of an atom including the 3 sub-atomic particles and their charges.
What is include nucleus, proton (+), neutron (0), and electron (-)
500
What are the three types of rocks, and how are they formed?
What is sedimentary- formed from other particles of rock and sediment that has been weathered and then cemented or compacted into rock. Igneous- formed from cooling lava, metamorphic- rocks that have been heated and pressurized to make new rocks.
500
Explain the difference between the independent variable and the dependent variable. Use an example.
What is an independent variable is the one thing in the experiment that the experimenter changes. The dependent variable is what is measured.
