4th Quarter Science with Mrs. Logston
Matter and Energy
Class is Every Tuesday and Thursday.
Matter and energy is in everything we see or touch as we go about our daily lives. We will learn about what makes the different elements in matter and explore energy as it applies to simple machinery.
· Describe the basic unit and properties of matter
· Examine physical and chemical properties of common objects
· Explain the relationship between force and motion
· Describe simple machines and their applications
Course Assessments (Graded Items):
The only homework that will required for this course will be studying for the end of unit quiz and turning in egg drop project on time. To be eligible to receive full credit projects must be turned in on the due date. Students will receive ½ credit for a project that is turned in the next class period after the due date. No credit will be given for projects that are later than the following class. In-class assignments and class participation will be graded. Failure to complete and turn in assignments on time will affect a student’s grade.
There will be one test at the end of the unit. This test will cover vocabulary; understanding of matter, force and motion; and simple machines. Test will be given on Tuesday, May 3, 2016.
The students will be assigned one project for the quarter. The project is an Egg Experiment to be completed at home and brought into class on Tuesday, April 26, 2016.

Egg Drop Project Due April 26, 2016
Students will use the following scientific method to conduct the egg drop project.
Question: What materials would protect an egg in an egg drop experiment?
Construct a hypothesis: You will need to write an if then statement that will answer the question.
Conduct the experiment:
- Only raw, store bought chicken eggs-size large-may be used. Your design must not include changing the egg in any way (no tape on the egg, no nail polish on the egg, no soaking the egg in vinegar, freezing, no hollow eggs…) You must supply the egg to be used in the project.
- No glass of any kind may be used in the design, for obvious reasons.
- The package must be able to be opened so that we may check on the condition of the egg. The inside materials must be designed to allow a raw egg to be easily inserted and removed.
- ALL EGGS NEED TO BE PLACED IN A SANDWICH SIZE BAGGIE, SEALED AND THEN PLACED INTO THEIR PROJECT.
- No balloons.
- No jello, peanut butter, pudding, liquids.
- Dropped from 7 feet
Results: Document what happened during the experiments at home until you have a successful egg drop.
· You will need to list each experiment conducted, materials used and what happened during each test. If the experiment is unsuccessful list why you think it was.
· Once you have a successful egg drop this is what you will need to bring to school to prove it worked by dropping it in the classroom in front of your peers.Conclusions: explain why the materials used made your egg drop experiment successful?
Study Guide for end of matter, energy and simple machines unit.
Condensation-gases change to a liquid.
Gravity-a force that the earth exerts on all objects.
Friction- resistance caused when two things rub together
Inertia- an object will keep doing what it is doing until a force acts upon it.
Motion- the physical moving of an object caused by force.
Magnetism- a force that either repels or attracts an object that is metallic.
Force- a push or pull on an object without a force there is not motion.
Isaac Newton’s Laws of Motion:
Law one- unless acted upon by an outside force, an object at rest will remain at rest, and an object moving in a straight line will continue moving in a straight line.
Law two-the change in an objects motion depends on its mass and the force acting upon it.
Law three-for every action, there is an equal and opposite reaction.
The only state of matter that can have all 3 stage’s is water. Solid-ice, liquid-water, gas-steam
The 6 simple machine names are:
Pulley-A wheel with a grooved rim in which a rope can run to change the direction of the pull and so lift a load.
Gear-A wheel with teeth around its rim that mesh with the teeth of another wheel to transmit motion.
Wheel and axle- two wheels of different diameters attached and rotating on the same axis.
Wedge- a double inclined plane that tapers to a point or sharp edge, used to change the direction of force.
Inclined plane –a flat surface set at an angle, used to change the direction of a force.
Lever-A beam, free to pivot around a point, used to move a load.
Screw-inclined plane spiraled around an axis.
