This 5-E lesson plan requires second graders to use observations and the engineering design process to test a variety of materials and decide which would make the best rain-proof roof for a doghouse.
K-2-ETS1-3 Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs. Clarification Statement: none Assessment Boundary: none
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation Students can compare different roof materials in terms of how they perform under model rainfall, and analyze the strengths and weaknesses of each.
2-PS1-2 Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose. Clarification Statement: Examples of properties could include, strength, flexibility, hardness, texture, and absorbency. Assessment Boundary: Assessment of quantitative measurements is limited to length.
Comments about Including the Performance Expectation Students will test a variety of materials and use observations to decide which materials are best suited as a roof to withstand rainfall.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice Students will explain why roofs are important and what features are needed to make a good roof and design solutions to the problem of building the best roof for a doghouse to withstand rainfall.
Comments about Including the Science and Engineering Practice Students can collect qualitative data in a chart as they test different materials under spray bottle "rainfall"; discuss observations with group members; interpret data to determine whether each material was effective; and explore an online application that tests different materials
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea Students will test different materials and compare how they stand up to a model of rainfall and discuss the different roofs that were tested and identify the best-performing roofs and the properties they had in common.
Comments about Including the Disciplinary Core Idea Students will test materials' suitability for use as a roofing material; discuss properties of materials observed in the activity; observe varied home designs and discuss properties of different materials used to build them; and discuss which properties are better suited for a shower curtain or T-shirt.
This resource is explicitly designed to build towards this crosscutting concept.
Comments about Including the Crosscutting Concept Students can examine how the properties of different materials affect function, as they test their properties under "rainfall" and discuss why a rigid roof is important to hold up against rainfall (can be extended to snowfall). Students will also compare materials and explain what make them suited or not suited for use as a roof material.
