Static charge12 objectives
- Describe how insulating materials can become charged when rubbed together.
- Explain that negatively charged electrons can be transferred from one material to another by rubbing.
- Explain that a material gaining electrons becomes negatively charged.
- Explain that a material losing electrons is left with an equal positive charge.
- Describe how charged objects exert forces on each other when brought close together.
- State that objects with the same type of charge repel.
- State that objects with different types of charge attract.
- Identify attraction and repulsion between charged objects as non-contact forces.
- Describe the production of static electricity by rubbing surfaces.
- Describe sparking caused by static electricity.
- Use electron transfer to explain static electricity phenomena.
- Describe evidence that charged objects exert attraction or repulsion without contact.
Electric fields10 objectives
- Define an electric field as the region around a charged object where another charged object experiences a force.
- Explain that a charged object creates an electric field around itself.
- State that an electric field is strongest close to the charged object.
- State that an electric field gets weaker further from the charged object.
- Explain that a second charged object placed in an electric field experiences a force.
- Explain that the force between charged objects gets stronger as distance decreases.
- Draw the electric field pattern for an isolated charged sphere.
- Use the concept of electric fields to explain non-contact forces between charged objects.
- Use electric fields to explain electrostatic phenomena such as sparking.
- Apply WS 1.2 and WS 1.5 when representing and explaining electric fields safely.
