It's the classic Newton vs. Einstein battle
This time we have Newton's Force Model vs Einstein's Acceleration model of Gravity According to Newton gravity is a force that pulls matter to the ground.
According to Einstein, the Earth is actually continually accelerating upwards and an object is not pulled down by gravity, but pushed up on by the Earth. Einstein was able to show that gravity is not a mysterious, invisible force—it is the curvature of spacetime. This curved spacetime model asserts that you feel heavy because the surface of Earth is forever accelerating up without actually moving up. (Perimeter Inspirations) |

How do Atom's exist?
Opposite charges attract. In this activity we learn that an electron can neither move or stand still as each scenario has it collapsing into the nucleus. We learn that electrons act like waves and can be at many points around an atom at the same time! |
|
Does Time Travel exist?
Your speed and perception of time is all relative. That is, it depends what you are comparing it to. For Special Relativity to apply: ALL Physical laws are the same due to constant speed The Speed of light is always the SAME |

Matter and light have properties of both waves and particles simultaneously. The results of quantum mechanics make it clear that waves exhibit particle-like properties and particles exhibit wave-like properties, depending on the specific experiment. Quantum physics is therefore able to make descriptions of matter and energy based on wave equations that relate to the probability of a particle existing in a certain spot at a certain time.

Atoms are made up of three different particles.
Protons are positively charged particles. Neutrons are neutrally charged particles Electrons are smaller negatively charged particles. The number of Protons in an Atom determines what type of element it is. Isotopes are elements with the same number of protons but with different numbers of neutrons, and consequently a different Atomic mass.

Radioactivity is the spontaneous disintegration of an unstable atomic nucleus and the emission of particles or electromagnetic waves.
We will study 3 Types: Alpha Beta Gamma |
Transmutation describes a process by which an unstable atom of a given element changes into another element
Alpha Decay is when an alpha particle (or helium nucleus) is released, creating an atom of a different element Beta Decay is when a beta particle (or electron) is released from the nucleus. This happens when a neutron breaks up into a proton and an electron. Gamma decay is the release of excess stored energy from the nucleus. This type of decay does not cause a transmutation. Therefore, a new element does not result. |

A radioisotope is an isotope that is radioactive.
Radioisotopes spontaneously disintegrate into different elements by emitting alpha or beta particles. The rate at which a radioisotope emits decay particles is completely independent of temperature, pressure, or other factors that affect chemical reactions. The only factor that determines the rate of decay is the element itself. This rate is measured by a time called a half life. A half life is the amount of time required for one half of the atoms (or mass) in any sample of radioisotopes to decay. |

Some heavy atoms, like uranium, can capture slow moving neutrons.
This process splits the nucleus of the isotope into lighter elements and releases ?huge amounts of energy. Furthermore, other neutrons are released from the nucleus providing opportunities for nearby atoms to experience a similar type of reaction. Fission is the process of splitting a heavy nucleus into two or more smaller nuclei by using a neutron. |
After fission occurs, neutrons from the parent nucleus are expelled as products.
These neutrons are capable of causing other nuclei to undergo fission if they are slowed by a moderator. This process can repeat for some time. A sustained fission reaction caused by these free neutrons is called a chain reaction. |
|
|
Nuclear fusion occurs when two
small nuclei join together to form a larger nucleus. As with fission, fusion releases enormous amounts of energy. |
The CANDU (Canadian deuterium uranium) is a controlled fission reactor that uses uranium as a fuel to produce electricity.
