If you’re in a rush to sell and have a car that isn’t one of the market darlings or is in rough condition, it’s gener- ally best to price it close to the market value and be prepared to take market or less to make a deal happen quickly. But if your car is one of the current hot sellers, you could probably get away with pricing it 10 to 20 percent over the market. | Teacher Information Rocket Car Objectives To construct a rocket propelled vehicle. To experiment with ways of increasing the distance the rocket car travels. Description Students construct a balloon-powered rocket car from a styrofoam tray pins tape and a flexible straw and test it along a measured track on the floor. Science Standards Science as Inquiry Physical Science - Position and motion of objects Science and Technology - Abilities of technological design Unifying Concepts and Processes - Change constancy and measurement Science Process Skills Observing Communicating Measuring Collecting Data Inferring Making Models Interpreting Data Making Graphs Controlling Variables Defining Operationally Investigating Mathematics Standards Mathematics as Problem Solving Mathematics as Communication Mathematics as Reasoning Mathematical Connections Measurement Statistics and Probability Patterns and Relationships Management This activity can be done individually or with students working in pairs. Allow 40 to 45 minutes to complete the first part of the activity. The activity stresses Materials and Tools 4 Pins Styrofoam meat tray Masking tape Flexible straw Scissors Drawing compass Marker pen Small round party balloon Ruler Student Sheets one set per group 10 Meter tape measure or other measuring markers for track one for the whole class technology education and provides students with the opportunity to modify their car designs to increase performance. The optional second part of the activity directs students to design construct and test a new rocket car based on the results of the first car. Refer to the materials list and provide what is needed for making one rocket car for each group of two students. Styrofoam food trays are available from butchers in supermarkets. They are usually sold for a few cents each or you may be able to get them donated. Students can also save trays at home and bring them to class. 35 Rockets A Teacher s Guide with Activities in Science .
