Lab 2: Magnet/Compass
Objective: Understanding the impact of magnet field
on a Compass.
Procedure: First put the compass on the
Northwest/Northeast corner of the table. Put the meter
stick adjacent to the compass and make
Exploring Objects in the Universe
Sight an object along the right edge and a piece of rope hangs down, the use of a
quadrant is simple. Using a quadrant, one can measure the altitude of a target
above the horizon from a given loca
We use angular diameters to conclude the distances of common objects. A scale
can be used to measure the angular diameter of an Object. By standing 200 cm
away from the wall which contained a paper plate one could measure the angular
diameter of that plat

Keplers second law states that planets sweep out equal areas of orbit in equal time
intervals. We were able to prove Keplers second
How Telescopes Work
A telescope is an optical device used to make distant objects appear closer. Refracting
telescopes use lenses to focus the light, and reflecting telescopes use mirrors.
During the lab we were able to buil

Objective: Calculating the equivalent weight of metal.
The equivalent weight of a substance is that weight of the substance that releases or combines
In a chemical reaction, one or more reactants is converted
to one or more products.
In this chapter we discuss three aspects of chemical

In 1916, Gilbert N. Lewis pointed out that the lack of
chemical reactivity of the noble gases indicates a high
degree of stability of their electron configurations.
A main challenge of chemistry is to
understand the connection between the
macroscopic world that we experience and the
microscopic world of atoms and molecules.
You must learn to think on the atomic level.

Chemistry is the study of matter.
Matter is anything that has mass and takes up space.
Matter can change from one form to another.
In a chemical change (chemical reaction), su
