Students will identify that the wind (moving air) can move objects and has power.
K-PS2-1 Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object Clarification Statement: Examples of pushes or pulls could include a string attached to an object being pulled, a person pushing an object, a person stopping a rolling ball, and two objects colliding and pushing on each other. Assessment Boundary: Assessment is limited to different relative strengths or different directions, but not both at the same time. Assessment does not include non-contact pushes or pulls such as those produced by magnets.
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation After students have listened to the story Gilberto and the Wind, they investigate three different stations about wind power. Then they test various objects to see if they can be moved (pushed) by wind. The term push is not used in the lesson so it should be added in the questioning and discussion sections.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice After exploring the wind stations, students are given materials to test in the wind (outside or inside with a fan) to see if the wind moves them. They collect data and compare the objects tested. To extend the lesson students may choose other objects to test in the wind to see how they move.
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea Students are exploring objects to see what different strengths are needed by a push from wind to move them. In some cases the direction of the wind may change the direction in which the object is moved. Students may think of objects they have at home they could move (push) by wind .
This resource is explicitly designed to build towards this crosscutting concept.
Comments about Including the Crosscutting Concept During the lesson various types of objects are tested by students to gather evidence to support or refute student ideas about the wind causing them to move. Students may write and illustrate a story about one of the objects they explore. Encourage students to design their own simple tests with objects of their choosing, in order to meet the full expectation of the crosscutting concept.
