Student Created Rube Goldberg Machines My students have designed, created, and executed their own Rube Goldberg Machines; showcasing what they have learned about work, energy, and simple machines. I am so proud of my up-and-coming engineers!

This is filmed in Slo-Mo so that each step is easy to analyze. What you are witnessing happens very, very fast in real time. media type="custom" key="28224423" align="center"

Profile of a Wave Exercise

GPS (Georgia Performance Standards) for this unit include:  S8P1. Students will examine the scientific view of the nature of matter. a. Distinguish between atoms and molecules.

b. Describe the difference between pure substances (elements and compounds) and mixtures. c. Describe the movement of particles in solids, liquids, gases, and plasmas states.

d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility).

e. Distinguish between changes in matter as physical (i.e., physical change) or chemical (development of a gas, formation of precipitate, and change in color).

f. Recognize that there are more than 100 elements and some have similar properties as shown on the Periodic Table of Elements.

g. Identify and demonstrate the Law of Conservation of Matter.

Homework

Always check the class calendar (above) to get specific details relating to homework that may be in addition to our "usual" homework assignments.

"The Usual" is 3 Daily Homework Expectations

1. Review the weeks' essential questions to see if you can add to them, or need to revise them in any way. 2. Always study your vocabulary! One of the best ways to make sure you succeed in Physical Science is to learn the vocabulary. Study the vocabulary every night, not just memorizing the words in the definition, but knowing what each definition means well enough to use it in conversation. 3. Any activities we begin in class, but you didn't finish in class, must be completed for homework.

ENDURING UNDERSTANDINGS Students will understand that: 1. Energy appears in different forms such as mechanical energy, gravitational energy, heat energy, and electric and magnetic energy. 2. Energy cannot be created or destroyed, but is only changed from one form into another. 3. Every object exerts gravitational force on every other object. The force depends on the mass of the objects and the distance between them. 4. Transformations of energy usually release some energy typically in the form of heat. 5. Heat energy results due to the disorderly motion of molecules. 6. Temperature changes as heat gets transferred. 7. Heat transfer occurs by conduction, convection, or radiation. 8. Velocity is speed in a particular direction and can be written as a positive or negative number. 9. Acceleration is how fast velocity changes and can be written as a positive or negative number. 10. Balanced forces result in an object remaining at rest or moving at constant velocity. 11. Simple machines are all around us, they reduce the effort to do work.
