Scholarship Science 9 Independent Study- The Air Car GOAL#1: Using the instructions provided, design and build an air car that will travel 30 feet and pass through a designated target area. (70% of project grade) Toy testing for 5% Materials list Electric motor bonus Propeller November 17, 18 & 9V battery clip 19th One wire lead with two alligator clips Four wheels 1 3/8” diameter with 3/32” tread width Two 9” length of 1/8” diameter dowel rod. Days to turn in Four straws 9/64” diameter X 5” length. completed (Some replacement parts are available for purchase at school if needed.) Posters/PowerPoint You will need to keep your car in a proper sized box for storage when turned in. Construction requirements The car presented for the final design must include the electric motor, propeller, wheels and dowel rod (used as axels only) provided in class. The motor may be connected to a battery however you choose to do so. Any type of tape or glue may be used in the construction of the car. The following items may NOT be used in the construction of the air car: o Legos, K’NEX or parts from any other construction sets. o Any parts from a car “kit” (e.g. CO2 car) o Any parts from any type of toy car or model car for possible 5% bonus December 1-3rd Posters/PowerPoint due by December 10th EVERYTHING due Demonstrating the Air Car for a final grade December 10th no You will demonstrate your car at school on the final presentation day. later than 3 PM NO materials will be provided to students on final presentation day. The cars may not be touched once they pass the starting line. You will have THREE free attempts to successfully demonstrate the car. 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 car. 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 car 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. (30% of project grade) Poster Requirements The poster should meet all requirements of the grading rubric. The poster should contain the following components: o Appropriate Title o Digital photograph of final design o More than one picture may be needed to adequately display car. Print on plain white paper. Show all parts labeled correctly. Show all dimensions of the car in centimeters. o Sequence of energy conversions (flow chart) taking place in the car 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: 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. PowerPoint Requirements The PowerPoint should meet all requirements of the grading rubric. 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 car. Show all parts labeled correctly. Show all dimensions of the car in centimeters. o Sequence of energy conversions (flow chart) taking place in the car 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: 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 car. Arrows are to be included on the chart to interconnect energy types. 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. Print out finished Power Point (at minimum energy conversions) to turn in to instructor on due date. o This does not have to be in color. IMPORTANT NOTICE! If on the scheduled day the project is due a student is absent due to a field trip, inschool performance, out of school trip, etc. then the student must demonstrate the car for a final grade the day before. If a student is on a preplanned absence (i.e. vacation, surgery) the day the project is due then the car must be demonstrated the last day the student is in school before the absence begins. If an unplanned absence (i.e. illness) occurs on presentation day, the project will be presented on the students’ first day back from the absence. Students may need to make alternate transportation arrangements for presentation before or after school. Flow chart example A A B B A ball starts from the top of the hill at point A and rolls to a stop at point B. The energy flow chart for this action is shown below. The energy flow chart for this action is shown below. Kinetic Sound The ball emits sound as it moves. Potential Gravitational The ball starts at the top of the hill. Kinetic Mechanical The ball begins rolling down the first hill. Kinetic Heat There is friction between the ball and the surface. Kinetic Sound The ball emits sound as it moves. Potential Gravitational The ball gains gravitational energy as it rolls up the smaller hill. Kinetic Mechanical The ball begins rolling down the second hill. Kinetic Heat There is friction between the ball and the surface.

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 The ability to do work Additional information may be found in your textbook.
