This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.
Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.
This is a 21 day unit on the topic of floods. Students will plan and prepare for what might happen in the event of a flood in our area. We have had floods in the past that have affected the Walterville School, its campus, and the surrounding areas. Using this as a springboard, students will discuss the effects of flooding, do research and interview family members who have experienced flooding, and then discuss possible ways to prevent significant damage on the buildings and surrounding areas. They will then design a barrier that could protect an area from damage for a period of time. Students will need materials to conduct experiments. We have listed these in the lesson plan. We have also included a trip to the Leaburg Dam so that students can learn about dams and their uses. We plan on teaching this unit in the fall.
Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. The module begins with plenty of hands-on experience using a variety of tools to build practical measurement skills and conceptual understanding of metric and time units. Estimation naturally surfaces through application; this transitions students into rounding. In the modules final topics students round to assess whether or not their solutions to problems solved using the standard algorithms are reasonable.
Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property of thermal energy that engineers use in many applications.
Students embark on a scavenger hunt around the school looking for indoor air pollution and mapping source locations.
Students are introduced to brainstorming and the design process in problem solving as it relates to engineering. They perform an activity to develop and understand problem solving with an emphasis on learning from history. Using only paper, straws, tape and paper clips, they create structures that can support the weight of at least one textbook. In their first attempts to build the structures, they build whatever comes to mind. For the second trial, they examine examples of successful buildings from history and try again.
In this unit of study students learn how patterns can be used to predict weather. They also learn about how climates vary in different regions of the world. Finally, students learn how to create a structure that can withstand weather conditions in different climates. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.
