Air under Pressure

Develop a model to describe that matter is made of particles too small to be seen. [ Examples: adding air to expand a basketball, compressing air in a syringe, dissolving sugar in water, & evaporating salt water.]||Next Generation Science Standards||Grade 5||Physical Science||Matter and its Interactions|||Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object & the mass of the object.||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions |||Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, & its acceleration. [Objects subject to a net unbalanced force, e.g., an object falling , rolling down a ramp, or a moving- pulled by a constant force.]||Next Generation Science Standards||High School||Physical Science||Motion and Stability: Forces and Interactions
