Scholarship Science 9 Independent Study- The Comeback Toy
GOAL#1: Using the instructions provided, build a come-back toy that will roll a minimum of four meters and return to its starting point. Demonstrating the comeback toy for a final grade You will demonstrate your toy at school on the final presentation day. NO materials, including rubber bands, will be provided to students on final presentation day. The toys may not be touched once they pass the starting line. The toy must start and remain on the ground when moving. No bowling! You will have THREE free attempts to successfully demonstrate the toy. o A fourth attempt will cost 5% of your final grade (20 points). o A fifth attempt will cost 10% of your final grade (40 points). o No more than five attempts will be allowed. On final presentation day 10% will be deducted from your final grade for each occurrence of the following: o Changing the design of your toy. o Receiving assistance before or between attempts.
Extra credit options (You may earn up to 10% extra credit) You may earn a 5% bonus by testing your toy at school on one of the scheduled testing days. You may earn a 5% bonus by submitting your completed poster or PowerPoint no later than one week before the due date. o All parts of the poster or PowerPoint must be completed. o The poster or PowerPoint must earn at least three scores of 4 and one score of 3.
Goal#2: Students will submit either a poster or a PowerPoint as part of their Independent Study.
Poster Requirements The poster should meet all requirements of the grading rubric. The poster should contain the following components: o Digital photograph of final design o More than one picture may be needed to adequately display toy. . Print on plain white paper or photo paper; your choice. . Show all parts labeled correctly. . If your toy is made from an opaque or translucent cylinder, you will need to take a picture of the toy disassembled with all the parts displayed. . Show all dimensions of the toy in centimeters. o Sequence of energy conversions (flow chart) taking place in the toy . A minimum of SIX types of energy with FIVE energy conversions should be included. Types of energy may be used more than once. . Each type of energy will be listed on a 3” X 5” index card and attached to the poster. . Each index card should include the following—labeled in this order: The classification of energy as potential or kinetic. The type of energy. An explanation of how this type of energy relates to the movement of the device. . The information should be handwritten on each card by the student. . Arrows are to be included on the chart to interconnect energy types. Poster Design Use 22” X 28” poster board. The digital photograph and energy flow chart should be located on the front of the poster. The student’s name and class period should be placed on the back of the poster.

The PowerPoint should contain the following components: o A title slide that includes name of student. o Digital photograph of final design . More than one picture may be needed to adequately display the toy. . Show all parts labeled correctly. . If your toy is made from an opaque or translucent cylinder, you will need to take a picture of the toy disassembled with all the parts displayed. . Show all dimensions of the toy in centimeters. o Sequence of energy conversions (flow chart) taking place in the toy . A minimum of SIX types of energy with FIVE energy conversions should be included. Types of energy may be used more than once. . Each energy description should include the following and be labeled in this order: The classification of energy as potential or kinetic. The type of energy.

PowerPoint Design There should be a minimum of three slides. More may be used if needed. o Title slide including student’s name o Slide of digital photograph o Slide of energy conversions Use Tahoma, Verdana or Arial font. There should be no distracting animations or slide transitions. Choices of slide background and font color should make text easy to read. Flow chart example

Energy Introduction for Scholarship Science 9
Energy Energy enables physical work to be done. Energy is a property a body has that helps it move against a force. Physical work is done when something moves against a force. o This needs a transfer of energy to take place. o Work is done when we lift an object from a table onto a shelf. . We are lifting the weight (a force) upwards. . Energy is transferred from our arm to the object.
Types of energy Potential- Energy that is stored in a body and has the potential to do work. o Chemical . Energy a body has because of what it is made of. . Present in a battery, explosives, food, gasoline o Elastic . Energy stored when something is stretched or compressed. . Present in a pulled rubber band or squashed spring. o Gravitational . The energy a body has because it is near something . When we lift an object up, we transfer energy to it. . We say that it gains gravitational potential energy. . The higher the object is lifted the more gravitational energy it will gain. o Nuclear . Energy stored in the nucleus of atoms that can be released during fission, fusion, or radioactive decay. Kinetic- Energy a body has because it is moving. o How much kinetic energy a body has depends on its speed and mass. o Heat . Energy transferred from hot regions to cool regions because of the temperature difference between them o Sound . Energy moving through a medium causing a vibration o Electrical . Kinetic energy of moving charges in an electrical circuit o Electro-magnetic . Energy carried by electromagnetic radiation, such as light or X-rays. o Mechanical .
