Ecology
This is the hydrosphere.
What is all of the water (oceans, lakes, rivers) on the Earth?
This is the third group of elements on the periodic table after metals and non-metals.
What are Metalloids?
A pair of electric charges will repel when they are like this.
What is "like charges" or "same charges"?
Accept Positive-Positive or Negative-Negative as correct.
Stars are made, mostly, out of these two elements.
What are hydrogen and helium?
A food web and food chain are different because of this.
(Or an answer similar to that)
This is element 19 on the periodic table.
What is Potassium?
List three ways that we can generate electricity
1) Solar (Using the Sun)
2) Hydro (Using water)
3) Thermal (Using steam)
4) Windmill (Using Wind)
A blue star is considered this on a temperature scale.
What is hot?
An aluminum atom loses 3 electrons turning into this type of ion.
What is a cation?
In the carbon cycle, carbons move from the atmosphere into plants through this process.
What is Photosynthesis (plants take in CO2)?
This is the number of electrons in oxygen.
What is 8?
This is the difference between static and current electricty.
What is static is a charge on the surface of objects, and current is a charge that moves in one direction through a conductor?
This planet is nicknamed "Earth's sister" due to their similar size.
What is Venus?
The two types of observations we make in science.
What are qualitative and quantitative?
What is respiration?
When sugar and oxygen are used to create energy for living things. This will release carbon dioxide and water
This is how to find the number of neutrons in an atom.
# neutrons = mass number - atomic number
These are the two types of circuits that we learned about in class.
What are series and parallel?
The universe will likely end in one of these 3 ways.
What is continue expanding forever, steady-state (not growing or shrinking) or oscillating between Big Bangs and Big Crunches?
This is the name for when a solid transforms directly into a gas, without becoming a liqud first.
What is sublimation?
When there are no more decomposers (worms, fungi, bacteria) this happens.
- The dead organic matter would build up
OR
- The plants would not get the recycled nutrients
As you move down the periods (rows) of the periodic table this happens to the Bohr Rutherford diagrams.
The amount of valence shells increase as you go down the periods
This is the type of object at the center of the Milky Way Galaxy.
Satellites do not float away or crash back into Earth because of these two things.
What is the satellite's speed AND the force of gravity?
Dust collects on computer screens. Use static electricity to explain why this happens.
What is:
1) The screen will be slightly charged when on
2) Nearby dust may have the opposite charge be closer to the screen
3) The opposite charges will cause the dust to be attracted to the screen
