Science in the community-(Unit #2 Isaac Newton)

Newton BONUS: Visit the Aquatic Center or a local park and find somewhere that uses Newton’s laws of motion.

The students are learning all about Newton’s laws of motion and gravity, and also about mass and weight. Mass is how much matter is in an object. Weight is how much gravity is pulling on an object. Gravity pulls harder on the thing that has the greatest mass (or is the heaviest). They will be using all of this information when building their angry birds marshmallow catapults and roller coasters. Have fun making a splash and diving into physics!!

Angry Birds Are Mad About Physics- (Unit #2 Isaac Newton)

“To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me.”

In this unit we will be highlighting Isaac Newton and working with gravity, physics, engineering and mathematics. He taught the law on gravitation, the theory of gravity and invented calculus to explain it. He also came up with the theory on ocean tides which explained high and low tides because of the moon’s gravitational pull and he’s known for the reflecting telescope.

Example of Newton’s laws of motion: 1st law: The law of inertia. E.g. -A soccer ball will not move until a player kicks it. 2nd law: F=MA (Force = Mass X Acceleration). E.g. – You have to push a heavy ball harder to get it to move as fast as a small one. 3rd law: For every action, there is an equal and opposite re-action E.g.- A fireman turns on his hose and is knocked backwards.

In class we will be making angry birds marshmallow catapults. We will talk about the angles in math and how you have to aim to knock over the pigs. Also, how if you pull back further, the birds will go farther.

Where in the world is Mrs. Westwood’s Science Class? (Unit #1 Albert Einstein)

“The important thing is to never stop questioning.”

During our first unit, we will be highlighting Albert Einstein and working in the fields of physics, energy, and technology. Albert Einstein is the father of modern physics. He came up with the world’s most famous equation E=mc2 (Energy = mass X the speed of light squared) which gave birth to the atomic bomb. He provided evidence that molecules and atoms exist through Brownian motion.

He basically re-wrote the law of gravity, which had been unchallenged since Isaac Newton. His theory of relativity has changed the way we think about space and time. He showed that matter causes space to curve, which produces gravity.

Example of the theory of relativity used today: GPS

In class we will be learning about how to use coordinates and GPS. We will also used Google Earth in class and pin-point our exact location.
