Unit Prject Descriptin: Using Newtn s Laws f Mtin and the scientific methd, create a catapult r trebuchet that will sht a marshmallw at least eight feet. After building and testing yur machine at hme, yu will use yur data t write a full reprt described in detail belw and n the rubric. The reprt is the majrity f yur grade. By having these tw requirements, each student may earn a 95. T earn the remaining five pints, a target must be accurately hit frm five feet back. Each persn will be given five tries t hit this mark. Unit prjects cunt as tw test grades. Requirements: Build a catapult r trebuchet that: is n mre than 2 x 2 x 2 in size. is made f, but nt limited t, elastic materials, wd, plastic, r pvc pipe (ther materials must be pre-apprved). **Try t use materials yu already have arund the hme t build yur prject. the launcher must be able t hld a large and small marshmallw. the trebuchet must have a weight; catapults d nt have weights. Reprt: All materials must be listed. Prcedures must be numbered, sequential, and set-up must be illustrated. Quantitative Data: Test catapult r trebuchet 10 times with a small marshmallw and 10 times with a large marshmallw. Recrd distances f each thrw. Put abve data int a table t shw cmparisns. Create a graph using same data and label bth axes. Cnclusins: Make inferences accrding t data results. List pssible limitatins r errrs. -------------------------------------------------------------------------------------------------------------- I am aware that my child,, has a science prject due n and is wrth TWO test grades.

1. COMPARE: Hw did the flight distance f the small marshmallw and the distance f the large marshmallw cmpare? 2. ANALYZE: Cmpare yur results with yur given hypthesis (My catapult/trebuchet will sht any size marshmallw at least eight feet.) D the results supprt yur hypthesis? 3. IDENTIFY LIMITS: What pssible limitatins r errrs did yu r culd yu have experienced during yur trials? Hw might these limitatins affect yur results? After identifying the limitatins r errrs, adjustments shuld be made. Hw wuld these adjustments affect yur results? 4. APPLY: Use Newtn s laws t thrughly explain yur quantitative results and why ne size may have wrked better fr yur machine. Law Definitin Hw did it apply t yur prject? 1 st 2 nd 3 rd
5. INFER: Using yur results, what can yu infer frm yur data? (Why did the small/large marshmallw g further? Hw did Newtn s laws, mass, gravity, frictin, air resistance, and cntact frces apply?) 6. CONCLUSION: (Write a cnclusin restating yur hypthesis, test results, and inferences.)
