A Chemical Reaction is a process that occurs when two or more molecules interact to form a new product(s).
The highest class?
Kingdom
Name three contact forces.
E.g.
Friction, tension, air resistance.
True or False:
Moon is a source of light.
False
True or False: You can run around the lab and yelling with your friends
False
Tell the differences between chemical and physical change.
E.g.
-New substances are created in a chemical change.
-Physical change affects only physical properties.

False
Fill in the gap: Cooling a substance ________ the energy of the particles, causing them to ______________.
decreases, vibrate less.
Name all the levels of classification.
Kingdom, Phylum, Class, Order, Family, Genus, Species.
Explain how airplanes can fly.
An airplane has specially designed wings called airfoils that move the air on the top of the wing faster than the air below the wing, creating higher pressure under the wing. Energy flows from higher to lower energy levels; the difference in pressures above and below the wing causes the upward force called lift.
Explain how the moon cause 'neap tides'.
Neap tides occur around the first and last quarter phase of the Moon, when the Moon's orbit around Earth brings it perpendicular to the Sun.
Why should we follow the rules in the lab?
To ensure our safety
What happens to water (H2O) particles when it's heated? (In solid state)
Why is Dichotomous key so important?
Because it is used to identify different organisms, based the organism's observable traits.
Explain how magnetic fields work.
E.g.
Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.
