TO THE PARENTS-
the homework for the 3rd nine weeks for all classes are as follows:
GIFTED-3RD NINE WEEKS G.R.A.S.P. [GIFTED]
[GOAL]
You must convince the Board of Directors of the new city amusement park to buy your roller coaster design.
ROLE
You are part of a roller coaster design team.
AUDIENCE
The Board of Directors at “Islands of Fun" amusement park
SITUATION
The “Islands of Fun” amusement park wants to add a new roller coaster ride. Your job is to work together as a team to design a roller coaster and present your coaster design to the Board of Directors at “Islands of Fun".
PRODUCTS
Use provided materials (6 feet of 7/8-inch (inner diameter) foam pipe insulation [cut in half lengthwise], standard-size marble, masking tape[not duct tape], stop watch, flexible metric tape measure, balance) to construct a roller coaster with at least two “hills.” Conduct trials to be sure that the marble performs as planned. Once the roller coaster is performing acceptably, calculate the speed of the marble from start to finish for three trials. Find the average speed of the marble for the three trials. Calculate the work done by the marble in Newton meters.
Create a diagram of the roller coaster with labels and short explanations to show which parts demonstrate the following terms: speed or velocity, acceleration, friction, gravity, momentum, potential energy, kinetic energy, Newton's first law of motion. The diagram should include a data table for time and distance and the calculations for speed and work.
The presentation by the team should include a demonstration of the working roller coaster. The presentation must: give the name of the roller coaster; justify the design used in each part of the coaster; identify and explain the chosen terms; and provide the average speed of and work done by the marble.
GRADING STANDARDS
SC.6.13.2, SC.6.13.3
Roller coaster must use only approved materials and have three consecutive successful trials in which the marble stays on the track.
Diagram includes terms provided, correctly placed, with a short explanation for each, a data table with time and distance from three trials, the calculation of average speed, and the calculation of work done by the marble.
Presentation includes a demonstration of the working roller coaster, the name of the roller coaster, a justification of the design used in each part of the coaster, identification and explanation of the chosen terms, the average speed of the marble for the three trials, and the work done by the marble.
ADVANCED-3RD NINE WEEKS G.R.A.S.P. [ADVANCED]
Goal:
To understand the relationship between electricity and magnetism.
Role:
You are a scientist for the world’s largest ship builder.
Audience:
Your audiences are the owners of the ship building company
Situation:
Your company has designed a compass to be used in emergencies at sea, but it doesn’t seem to be working correctly when it is located near the solenoids in the engine. You have been asked to design a test to determine the effect of the engine on the compass.
Products:
You need to design and create a test that will determine what is affecting the reliability of the compass. Your product must
include a labeled diagram of the engine part that is affecting the compass, the data that you collected and the final conclusions
in the form of recommendations for the owners.
Solenoid Directions
Materials and equipment (per group)
• battery (6V)
• compass
• iron rod, bolt, or nail
• metric ruler
• tape
• cardboard tube from paper towel
• wire with stripped ends (700 cm)
Label the ends of the tube A and B. With the tube horizontally, place a piece of tape 20 cm from the end of the wire Tape this spot to the A end 1 cm from the edge. Wrap the long end of the wire tightly around the tube 50 times without overlapping, but closely together. Tape the wire at B with 20 cm left over. Attach wire A to the battery.
Place the compass 2 cm from the B end Record your prediction, what will happen when you connect B wire to the battery
Record what actually happened
Next, predict what will happen if the iron rod is placed inside the tube.
Record what actually happened
Conclusion:
What was the effect of the iron rod on the compass?
What does this tell you about the placement of the compass?
