First Quarter Egg Drop Project Force Objective: Design a container that will protect the egg from the force of impact during free fall. Components: 1. Egg must be raw, white, large, untreated (no paint, glue, etc.). 2. Container cannot be larger than 25cm in any direction; mass maximum is 200 g. Mass should be as low as possible without sacrificing protection of the egg. Remember: a project that is too massive is detrimental; a project without protective materials will not prevent the egg from the impact due to force. 3. No materials can be to suspend the egg within the container. 4. No parachutes or fins may be attached to the container. Second Quarter Mobile Project Work Objective: Design and construct a mobile so that all arms are balanced in the horizontal component. Components: 1. The mobile should have a minimum of three freely swinging arms as well as a general theme to enhance design merit. The three arms must be independent of each other, not crisscrossing. The design of the mobile should allow for full 180-degree turns of each arm without collisions. 2. The arms cannot be centered off one string. It is recommended that the top arm's supporting string be centered. 3. Plan to use 3/16-in to 1/2-in wooden dowels as arms. The diameter of the dowels is dependent on the weight of the objects. General Rule: the lighter the objects, the more narrow the diameter of the dowel. However, the dowel cannot bow under the weight of the objects, nor can a dowel have such a large diameter that the objects have no affect on the dowel arm swinging. 4. Select a minimum of nine hanging items for the mobile, using at least three per arm. 5. a. Sketch the general plan of the mobile on graph paper, using an appropriate scale. The sketch should provide an idea of how the mobile will look. b. Show the approximate length of each arm on the sketch, using the squares on the graph paper. c. Make a legend on the sketch that details all parts of the drawing (arms, objects, masses, lengths, etc.). 6. Find the mass of each item, as well as the mass of each painted and cut dowel. Record all measurements in the legend. 7. Calculate the position of the support string on each arm as well as that of the items.(Force x distance = Force x distance) Record measurements in the legend. Note: You will achieve the best results by starting with the lowest arm and working upward. Make a notch in the dowel for each string so that the object will not slip. 8. Allow plenty of time for the project as it will take longer than you think. 9. Make a list of five tips for next year's students. 10.Submit your sketch and all other written information in a three-prong folder with a title page. Bring all your supplies and arms in a box so your project will not get lost or damaged. Assessment: Finished Mobile 30%; Guideline Adherence 35%; Sketch with Legend 25%; Creativity 5%; Quality 5%; Bonus Best of Show 5%. Clarifications: Creativity Strive for interest in your design. Think of its visual impact. Vary the heights of dowels by balancing smaller objects with larger ones. Paint the dowels for effect. Quality This includes equilibrium of the arms, durability, neatness of construction, attention to design details, etc. Third Quarter Project Domino Project Energy & Simple Machines Fourth Quarter Project Electrified House Ohm's Law & Electric Circuits
