Lesson OverviewTitleHurry Up-Engineering a New PlanGrade Levels3rd GradeSubject AreaScience/MathSummary & RationalStudents often times do not have the opportunity to work in collaborative groups to solve a problem. This lesson provides them this valuable experience while at the same time exploring science concepts that may pique their interest in global warming and other environmentally based sciences. ReferenceLesson Retrieved from: Scientists who study global warming: Water Career Websites: Tasks/PlanningActivity DescriptionWorking in groups students will design and engineer a process to make an ice cube melt at a faster rate. Integrates matter and engineering.Materials/Resources NeededMaterials:ice cubes of the same sizecupsclockaccess to heat sources such as a windowsill or microwave.Resources:Background videos on matter and changes in states of matter are available on BrainPop and Discovery Education.Engineering resources: Plan Sheet: Time20 minutes to preview resources Academic StandardsScience (Next Generation Science Standard) 2-PS1: Matter and its Interactions. Observe Properties. 5-PS1-3. Matter and its Interactions: Make observations.Engineering (Next Generation Science Standard) 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.Mathematics (Common Core State Standard) CCSS.Math.Content.3.MD.A.1 Tell and write time to the nearest minute and measure time intervals in minutes.Student Friendly ObjectiveI can work cooperatively in a group to develop and implement a plan to make an ice cube melt at a faster rate.Students will be able to:? Suggest methods of speeding up the melting of ice? Cooperatively design and implement a plan to melt ice quickly? Cooperatively design and implement an improved plan to melt ice at an even quicker rateUnderstand that:? Water exists in all three states of matter.? Matter changes states.? The addition of heat causes matter to change from a solid to a liquid.? The removal of heat causes matter to change from a liquid to a solid.Know: ? Concepts of Matter? Effect of Heat on Matter? How to calculate elapsed timeDo:? Develop methods to speed up the melting of ice? Design and implement a plan to melt ice quickly? Calculate elapsed time? Reflect upon their results? Design an improved plan to melt ice at an evenquicker paceNavajo Culture ConnectionEvaluation/Assessment(Describe the task, the criteria/rubric, and goal for mastery)Learning that will need to be “checked” during the lesson to be sure students have a secure understanding of important content: Are groups demonstrating their understanding that the addition of heat is causing the ice cube to melt faster? Are groups developing plans that will cause the ice cube to melt at a faster rate? Are groups calculating the elapsed times correctly?ASSESSENT:Was the group able to develop and carry out a plan that would melt an ice cube at a faster rate than the class observation?1 Basic: Group was unable to develop a plan that melted the ice at a faster rate than the class observation.2 Approaching: Group needed assistance in developing a way to melt the ice at a faster rate than the class observation.3 Meeting: Group developed and successfully carried out a plan that melted the ice at a faster rate than the class observation.4 Surpassing: Group developed and successfully carried out a plan that melted the ice at a faster rate than the class observation and were able to explain their group’s design process.VocabularyMatterSolidLiquidMeltingTeaching ProceduresSTEM Career Connection (Anticipatory set-emphasize how you will make this career a relevant possibility for students. How will this lesson inspire them through this part of the lesson?)water industry jobs scientists who work in global warming related fields: climate and atmospheric scientists, oceanographers, and environmental scientistsI DO (Introduction to New Material-Task Analysis)Introduction-Open-ended question activity as a whole-group to assess prior knowledge of the affect heat has on matter.This lesson will begin with a class discussion to grasp the students’ prior knowledge of what causes matter to change from a solid to a liquid. The class observation of the ice melting will build their background knowledge regarding the affect heat has on matter.WE DO (Guided Practice/Small Group Lesson Activities)PartnersObservation-Class will observe an ice cube in a cup. Students will calculate the time it took for the ice cube to completely melt. Can work in small groups of 2-4 students to see if all groups calculate similar times. YOU DO(Independent Practice)PartnersConstruction-Students will work in groups to design a plan to cause their ice cube to melt faster. Implementation-Students will carry out their plan and calculate the time it took their ice cube to melt. Reflection/ Improvement-Students will reflect on their group’s results and design a plan to cause their ice cube to melt at an even faster rate. Final attempt-Groups will then carry out their improved plan and report their results/findings to the class.Lesson ClosureStudents can write and/or present “I learned the following new information…”Filed Trip OpportunityN/ATimeframeApproximately 1 hour of class time. ................
