1. Solar Oven & Egg Cage Project End of Year Graded Project 5 th Grade Science Ms. Mayville

2. 1.Question and Hypothesis presented (up to 12pts possible) Question clearly stated Testable hypothesis & in proper format - If (I do this..), then (this will happen). All materials identified for experiment 2.Procedure: (up to 8pts possible) Correctly listed all steps required to build their solar oven/egg cage picture(s) of construction (drawn or printed photographs) 3.Observations: (up to 16pts possible) SOLAR OVEN descriptive written observations recorded measurements (time and temperature) every 5 minutes Table of observations/temperature/time graph of temperature/time 4.Conclusion: (up to 4pts possible) conclusion based on their results 5.Follow-up Information: (up to 8pts possible) List any “human errors” that could have altered results described ways they could have improved their design *Additional Points (2pts): use of all recycled items Total Points: All added together _____ / 50 4 = excellent3 = adequate2 = partial 1 = needs work/not included EGG CAGE Descriptive written observations Recorded measurements (time & distance) Table of observations/distance/time Graph of distance/time

3. Design Requirements - Solar Oven design and build any style of cooker MUST use any non-toxic materials Only students are allowed to build their cooker -this is not a parent project. However, for safety reasons, students may have assistance with power tools Adults are encouraged to monitor the use of tools. The solar cooker may ONLY use solar thermal energy to heat the food. No additional power sources are permitted for heating food. Extra design points will be given for unusual designs and creative use of materials such as recycled items.

4. Cooking Requirements All cookers will be heating a S’MORE (chocolate & mini marshmallow between two graham crackers) in the cooking device. Melted chocolate & marshmallow 12”W x 12”L x 12”D The oven may be no bigger than 12”W x 12”L x 12”D. Each cooker must heat at least three s'mores at the same time within 25 mins. The cooker will be judged on appearance of s’more, time and temperature of cooker at end cooking time. (within 25mins)

5. Design Requirements – Egg Cage design and build any style of cage (NO PARACHUTE of any type) Only students are allowed to build their cage-this is not a parent project. However, for safety reasons, students may have assistance with power tools Adults are encouraged to monitor the use of tools 9”W x 9”H x 9”D The cage must be no bigger than 9”W x 9”H x 9”D 1.5lbs Weight of cage must be 1.5lbs or less Cage should be constructed to protect a raw egg from cracking/breaking from an 8ft drop Extra design points will be given for unusual designs and creative use of materials such as recycled items.

6. Class Competition Winners will be determined by: Solar oven best time to cook 3 s’mores at once to the desired results (up to 25mins) Appropriate melted chocolate and mini marshmallow Items held together for consumption Egg Cage No cracks/breakage of egg at end drop (impact) Condition of cage after drop Tie breaker will be based on student vote. Competitions will be held on Friday, May 29 and/or Monday, June 1 (based on weather) Participation in class competition is optional and winners will be reward a prize!
