Chemistry
God made all matter, energy, and the rules for how things interact.
Who made Chemistry? or Who made Physics?
Matter can be a liquid, a solid, or a gas.
What are the three states of matter?
The pieces of the sumo toy fall down because they stay at rest. The piece that was hit moved because a force acted on it.
How does the Sumo toy demonstrate the first law of motion?
Energy is what makes everything in the world work and do things.
What is energy?
Six simple machines are wedeges, screws, levers, pulleys, wheel & axles, and inclined planes.
What are six simple machines?
Atoms are made up of protons, neutrons, and electrons.
What are the three parts of atoms?
Atoms move faster in gasses than atoms in liquids and solids.
In which state of matter do atoms move fastest?
The bowling ball is heavier/has more mass and causes the soccer ball to change directions.
How does the bowling ball hitting the soccer ball demonstrate the second law of motion?
Insulators stop heat or energy from transferring.
What do insulators do?
We call it a simple machine because it uses only one type of machine.
Why do we call a machine a simple machine?
Atoms can bond/connect by sharing electrons (Covalent bonds) or by taking one electron from another electron and creating a magnetic like force (Ionic Bonds).
What are two ways atoms bond?
Trail Mix is a heterogenous mixture.
Is trail mix a homogeneous or heterogeneous mixture?
The air comes out of the open end of a balloon and the balloon gets pushed in the opposite direction.
How does the air coming out of a balloon demonstrate the 3rd law of motion?
Three ways heat is transferred are convection, conduction, and radiation.
What are three ways that heat is transferred?
FLE - 123 reminds us what part of the lever is in the middle for each class of lever. (Fulcrum, Load, Energy)
What does FLE - 123 remind us about levers?
Vinegar is an acid and soap is a base.
What is an example of an acid and a base?
When the north poles of two magnets are pushed near eachother they push apart.
What happens when the north poles of two magnets are pushed near eachother?
Sound waves need something to vibrate. They cannot move through empty space.
Can sound waves move through empty space?
Three things fire needs are heat, fuel, and oxygen.
What are three things fire needs?
On the table are three types of levers. Put them in order by class.
What are examples of the three types of levers?
Soap has a hydrophilic (water loving) head and a hydrophobic (water repelling) tail. Soap's tail attaches to dirt/oil and its head attaches to the water to wash the dirt away.
How does soap work?
The squares in the periodic table give the atomic number, the atomic symbol, and the atomic weight of an element.
What information is given in a square on the periodic table?
A crystal can bend light waves separating them into the colors of the rainbow.
What can a crystal do to light waves?
An electrical circuit needs to be closed to light a lightbulb.
Does an electrical circuit need to be open or closed to light a lightbulb?
A double pulley system cuts in half the effort needed to lift the same weight.
How does a double pulley system give mechanical advantage?
