TISSUE PAPER HOT AIR BALLOON
By Andrea Badua . Period 2 . Physics
Introduction
Objectives/Purpose & Standard
With the provided materials, the student will plan, design, and construct a hot-air balloon that will stay longer in air, and that will explain the Physics of a Hot-Air balloon. Measure the height of the flight of the balloon and the time the hot- air balloon will stay in air. Explain how the hot- air balloon works. Investigate how temperature affects air density. Cite a global issue related to the project. 3a. Students know heat flow and work are two forms of energy transfer between systems. 3b. Students know that the work done by a heat engine that is working in a cycle is the difference between the heat flow into the engine at high temperature and the heat flow out at a lower temperature (first law of thermodynamics) and that this is an example of the law of conservation of energy. 2c. Students know the internal energy of an object includes the energy of random motion of the object’s atoms and molecules, often referred to as thermal energy. The greater the temperature of the object, the greater the energy of motion of the atoms and molecules that make up the object. 2g. Students know how to solve problems involving heat flow, work, and efficiency in a heat engine and know that all real engines lose some heat to their surroundings.
Problem & Hypothesis
How can we make the hot air balloon float in air for a long amount of time? If we use the blow dryer as a heat source for the hot air balloon, then the heat emanating from the device will make the hot air balloon float in air for at least five seconds.
Materials
Tissue paper Glue stick Pair of scissors Ruler Stop watch
Plan & Design
Procedures
Cut out 8 strips of the outline Glue one side to the other and Repeat. Glue a circle on the top to Prevent air coming out. Turn inside-out. Make the skirt and glue it on The balloon.
Data & Observation
