TRANSCRIPT
Atoms
• Atoms are in particles and particles are in everything.
• The three parts in a atom are protons, neutrons, and electrons.
• Everything you breath, touch, and see is made up of Atoms.
• EX: The air you breath, A pencil you hold, And everything you see.
Evaporations
• Evaporations is when a liquid is heated enough to turn it into a gas
• Ex: when a pot of water is on the stove and is boiling this cause evaporation which is the steam in the air
Laws Of Motion
• One… two…three… laws of motion.• Example 2- If you kick a soccer ball the ball
will keep going in one direction until it hits an object and the is ball sent in a different direction.
• Example 3- if you blow up a balloon then let it go the air coming out cause the balloon to fly around
• Example 1-if you shoot an arrow into space it will stay at the same speed until the friction slows it down.
Mechanical Energy
• Mechanical energy is potential energy and kinetic energy combined .
• Potential energy is stored energy.
• Kinetic energy is the energy of motion.
• A car on a ramp that is higher then another car that is farther down the ramp will travel faster
Electricity
• Electricity is a form of energy that’s involves the movement of electric charges.
• In atoms, if there is more proton then
electrons it has a positives charge.
• If it has more electrons then it has a negative charge.
Circuit
• A circuit is a line or route that starts and finishes in the same place
• Ex: A battery, one end is positive the other is negative. If you wrap a wire starting from the positive end and ending at the negative side this will recharge the battery.
Oceanographer
• An oceanographer is a person who studies marine life and ecosystems, ocean circulation, plate tectonics and the geology of the sea floor, and the chemical and physical properties of the ocean.
• It’s compared to physical science because they look to see how much force the waves do.
