1 Honors Summer Research
2 ._ "'" - Scientific Method and Air 1. Research the meaning of "Physical Science' 2. Research the scientific method (what it is and if there are any steps involved). 3. Why is it important to follow the scientific method? 4. What is the difference between a fact, a hypothesis, a theory, and a law? 5. Define scientific notation and explain how it is used. 6. Research the meaning of "Environmental Science' 7. Research the properties of air. 8. Research the composition of air. 9. What is viscosity? 10. Research Bernoulli's Principle. 11. What are the forces involved in the flight of an airplane 12. Research the force that allows a hot air balloon to rise. 13. Research how air pollution is detected. 14. Research common air pollutants (what they are and their sources).
3 Motion and Force 1. Research Sir Isaac Newton. 2. What is motion? What is velocity? 3. When you are in a car traveling at a steady velocity for a known amount of time, how can you determine how far you have traveled? Determine the following: Joe jumped on a trolley that was traveling at a steady Smiles per hour and he rode it for 1 hour and 45 minutes then jumped off. How far did he travel? Sue slipped off a bridge and landed on a trash barge that was traveling at 25 miles per hour. She had to travel for an hour and a half before they docked so she could call home. How far did she travel? 4. When there is a vehicle moving for a known amount of time and a known distance, how do you determine your average velocity? - Determine the following: Max got in his car and traveled for 2 hours and 30 minutes to get to his destination 40 miles away. What was his average velocity? Bev got on her bike and traveled to the store 3 and a half miles away. If it took her 45 minutes to get there what was her average velocity? 5. What is acceleration? What units are used for acceleration? What is 'constant acceleration'? 6. What is a force? What units are used for force? 7. When something falls on earth, what forces are involved? 8. What is gravity? What is the value assigned to gravity, close to the surface of the earth? 9. How do you determine a falling object's velocity at a given amount of time? Determine the following (assuming there is no air resistance): What is the velocity of a rock falling off of a cliff after ½ second? What is the velocity after 1 second?

5 Energy 1. Research the meaning of energy. 2. Research the difference between kinetic energy and potential energy. If you know the mass of a moving object and its velocity, how can you find its kinetic energy? Find the following: The mass of a truck is 900 kilograms (which is roughly 2 tons), and it is traveling at a speed of 25 meters per second (which is roughly 55 miles per hour), what is its kinetic energy? The same truck has slowed to 1 lmeters/second (which is roughly 25 miles per hour), because it is in a school zone. What is its new kinetic energy? State at which speed the truck would do the most damage to an object that was standing still, and state why. If you know the mass of an object and its height above the ground, how would you find its potential energy? Find the following: The mass of the boulder is 454 kg (which is roughly 1 ton) and is at the top of the hill which is 61 meters high (which is roughly 200 feet), what is its potential energy? The same boulder rolled down the hill and stopped 15 meters (which is roughly 50 feet) from the bottom, what is its new potential energy? State at which height the rock would do the most damage to an object standing still if it fell and state why. 3. Research the Kinetic Theory of Matter. 4. Research the difference between temperature and heat. What units are used to measure temperature and heat? 5. Research heat, including how it is transferred, its sources, how it is produced and how it affects matter. 6. Research contraction and expansion. \ MORE QUESTIONS ON THE NEXT PAGE
