Science Guide

Orientation
1. Explain benefits and define strategies for successfully working with a module partner
the benefits are that you can divide responsibilities and you can share the use of the equipments as you work as a team
2. Compare the module guide to the post test, including similarities and differences
the module guide is in the beginning of the session and it is toknow what you all ready know, the post test is after the sessions and it is about what you learned in the modules. Module guide doesn’t count and post test does. They are both multiple choices and have 10 questions each.
3. What does acronym RCA stand for?
research, challenge and application
Applied physics
1. Differentiate between insulators and a conductor
an insulator doesn’t conductelectricity well. Charged particles called electrons are not free to move and can’t carry a current. Examples of insulator: plastic, glass, drywood, robber. Insulator such as metals is free to move through material and carry the electrical current. Examples of conductors are: all metals(silver, iron)
2. List the steps of sciencetific method
-observation
-objective
-state hypothesis-experiment
-theory
-make conclusions
3. Explain hypothesis
in an idea or prediction of the result of an experiment
Dynamic Earth
1. identify at least 5 layers of the earth
crust, upper mantle, lower mantle, inner core, outer core
2. Describe the process of liquefaction
were the vibrations in the ground that cause the soil to act as a fluid. In the liquefaction structures that were atone time built on solid foundations can sink into the ground as the earth under heat.
Electricity
1. Define the terms voltage, resistance, current and circuit
voltage: the amount of force per electron growing through a substance
resistance: the opposition to the flow of electrons. It is measured in ohms
Current: the amount of electrons moving passed a given point in a given period of timemeasured in ampere
circuit: a path through which electricity flows from a negative terminal to a positive terminal.
2. Define and give examples of static energy
ions tend to try to neutralize themselves by repeating or attracting electrons. As ions attract and repel electrons, some electrons find themselves attached or only loosely attached to atoms. This causes an unbalance of positive andnegative charged particle.
3. Explain how electricity is related to electrons and protons
electricity if formed of energy that is associated with the built-up and movement of electrons and protons. The attraction between the positive charge of the protons and negative charge of electrons holds atoms together. Electrons sometimes become free of atoms and they create electricity.
4. Definea series circuit
several devices connected into one same path
Energy, power and mechanics
1. name the 3 nonrenewable and three renewable resources
renewable: trees, crops and animals
non renewable: oil, coal, petroleum, gas, iron, gold
2. Explain the three classes of levers
3. Give an ex. Of each class of levers
first class-seesaws, shovels, craw bars, scissorssecond-nutcrackers, wheel barrows, bottle openers
third-tweezers, ice tongs, shovels, scissors
4. Explain the following: fulcrum, lever, load, effort
fulcrum: is the fixed point on which the lever rotates
lever: a rigid bar that rotates around the fulcrum
load: the way of the object that is to be moved by the lever
effort: force that is required to move the load
Environmental issues
1. Explain thedifferences among renewable and nonrenewable and give 2 examples of each
renewable resources are those that are replaced in nature at the rate close to the rate of use
nonrenewable are those that are difficult , almost impossible to replace once they have been used.
2. Which atmospheric gas is naturally occurring greenhouse gas?
carbon dioxide
Forces
1. state Newton’s first law and...
