  • Air Is Not Nothing

    Book Chapter | April 2016

    In this chapter, the objective of the activity “Moving Air” is to experience air’s mass and the force it can exert on objects. Chapters 1 and 2 are also included in this book selection. Chapter 1 focuses on science…

  • Air That Moves

    Book Chapter | May 2019

    This activity is for testing how different speeds of wind make objects move. In the activity, students hold their streamers in front of an electric fan. By changing the speed of the fan, have the students describe and…

  • Air Cannon

    Book Chapter | February 2019

    The guiding question for this activity is,“How can air be used to move something?” Large air cannons can be made or purchased for students to experiment with while waiting to create ones of their own. An explanation of…

  • Air Quality

    Book Chapter | December 2016

  • Air Pressure

    Book Chapter | September 2014

    Gravity pulls the air molecules toward the ground, and the molecules push on the ground. This pushing is called air pressure or atmospheric pressure. In this chapter’s experiments, students will learn about air pressure…

  • Is It Air or Wind?

    Book Chapter | May 2018

  • Let’s Clear the Air

    Journal Article | January 2021

  • The bombs bursting in air

    Book Chapter | January 2006

  • Do They Need Air?

    Book Chapter | September 2013

    The purpose of the assessment probe, in this chapter, is to elicit children’s ideas about needs of living things. The probe is designed to find out if students recognize that all animals need air to live, including…

  • Friction and Air Resistance

    Book Chapter | September 2014

    Friction is very common and experienced every day. It is a force that pushes on things and that you notice when two objects’ surfaces are in contact with each other. Air resistance is a force that occurs because moving…

  • Air Quality Science for All

    Journal Article | April 2021

  • Air Pollution and Environmental Equity

    Book Chapter | September 2011
