Use models to explain that simple machines change the amount of effort force and/or direction of force.
In this unit, students analyze the phenomena of matter, forces, and energy. In this lesson, they compare the effects of unbalanced versus balanced forces on objects. They then evaluate how matter interacts with and is changed by energy, which transfers from one object or system to another. This page showcases key components of this lesson.
In this unit, students explore matter, forces, and energy. In this lesson, students evaluate the science phenomena of how matter interacts with and is changed by energy, which transfers from one object or system to another. This page is a high-level extract of the components of this lesson.
In this unit, students bring together what they have learned about the interactions of energy and matter to explore the science phenomena of relationships between energy, force, and motion. In this lesson, they investigate how windmills transfer the kinetic energy in wind so that it can be used to do work, and then use that knowledge to analyze balanced and unbalanced forces.
In this unit, students first use windmills to analyze how wind energy provides a force that causes windmills to turn. Then, in this lesson, they explore the science phenomenon of how patterns in motion can be used to predict future movements. This page provides a snapshot of key components of the lesson.
