TEKS & Objectives
7.7. Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy.
8.8.C identify how different wavelengths of the electromagnetic spectrum such as visible light and radio waves are used to gain information about components in the universe
7.2.B design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology
We will explore the relationship among force, motion, and energy.
I will investigate the practical effects of energy transfer.
1. Watch video.
Generation Genius Magnets & static Electricity 3-5
3. Review vocabulary and complete quiz.
Magnet An object that produces a magnetic field
Magnetic Field The invisible space where a magnet can exert its force on another object
Electromagnet A type of magnet that can be turned on and off using electricity
Static electricity A type of electricity that can be used to push and pull things at a distance; It is typically made by friction and causes things like dust to be attracted to you.
Attract To BRING TOGETHER, as with magnets of different charges
Repel When magnets with the same charges PUSH each other APART
3. Try the static electricity experiment from the video.
4. See more static electricity in action.
Blow up two balloons. Hang one from a string.
Rub the untied balloon against your hair to give it a static charge.
Slowly bring the static balloon toward the one hanging from a string. What do you observe?
Speaking of today’s topic…
What attracts knights in shining armor even more than damsels in distress?
Magnets
