A Classrooms Unleashed Program for
Throughout this unit, students work collaboratively to apply the three steps of the Engineering Design Process: Define the Problem, Develop Solutions, and Optimize. Students participate in three in-class lessons that integrate the second grade standards for Engineering Design. During each of the lessons, students have the opportunity to work with a partner or a small team to design, construct, and test their solutions to given problems. Students also discover why the three steps of the Engineering Design Process are important to solving real-world problems.
LESSON 1: Sink or FloaT?
During this 75-minute lesson students practice making predictions and recording data while conducting a sink or float investigation with a variety of objects. Students identify and discuss the three steps of the Engineering Design Process to choose the best solution for a boat design that can hold at least ten “passengers” using only one piece of aluminum foil.
LESSON 3: The discovery museum
During this 3-hour field trip, students travel to the Terry Lee Wells Nevada Discovery Museum! Students work in teams during a museum lab to build a skyscraper, journey on a scavenger hunt throughout the museum looking for properties of matter, and build more bridges out of wooden blocks in the Build-it Room.
LESSON 2: Roller Coasters
During this 75-minute lesson, students explore a variety of household items to gather information about the idea of motion and how energy causes objects to move. Students apply their knowledge of energy to design a solution to a problem. Students use the Engineering Design Process with a partner to sketch, construct, and test model roller coasters.
LESSON 4: Towers
During this 75-minute lesson, students make inferences about the strength of shapes and recognize how a variety of shapes are used in different types of structures. With a partner, students actively participate in each step of the Engineering Design Process to build a structure with certain criteria and constraints, using only a limited amount of materials.
ELA: W.2.8 - Recall information from experiences or gather information from provided sources to answer a question.
Mathematical Practices - MP2: Reason abstractly and quantitatively; MP5: Use appropriate tools strategically.
Next Generation Science Standards
K-2-ETS1-1: DCI's - ETS1.A, ETS1.B, ETS1.C SEP's - Asking Questions and Defining Problems
K-2-ETS1-2: DCI's - Developing Possible Solutions SEP's - Developing and Using Models CC's: Structure and Function
K-2-ETS1-3: DCI's - Because there is always more than one possible solution to a problem, it is useful to compare and test designs. SEP's - Analyze data from tests of an object or tool to determine if it works as intended.
