PET Jr. Lessons
I. Current Electricity
A. The Path of Electricity
B. Conductors and Insulators
C. What Lights up?
D. Switches
Content Learning Goals
Electricity must travel in a circle.
Batteries and light bulbs have two ends.
Electricity travels through most metals.
Switches work by breaking the circuit.
More batteries added in a series make the light shine brighter.
Nature of Science Learning Goals
Forming and testing predictions.
Recording and sharing observations.
Creating generalizations.
II. Magnetism
A. Magnetic Interactions
B. The Strength of Magnets
C. Push and Pull
Content Learning Goal
Magnets interact with different materials differently.
Magnets stick to some but not all metals.
Combining magnets can create a stronger magnet.
Magnets have two ends that are different.
Magnets push and pull.
Nature of Science Learning Goals
Students will understand that to conduct a fair test, only one variable can be changed.
III. Force and Motion
A. Cars and Ramps
B. Slowing Down
C. Newton's 2nd Law
Content Learning Goal
Higher ramps cause cars to travel farther before stopping.
Things slow down because the surface pushes against them.
Things slow down or speed up because of a push or a pull.
Measuring speed requires both a time and a distance.
Nature of Science Learning Goals
A relationship is when changing one thing effects another.
A fair test is when only one variable is changed.
IV. Light
A. Mirrors
B. Shadows
C. Pinholes
D. How We See
Content Learning Goal
Mirrors reflect light in only one direction.
Shadows occur when light is blocked by an object.
Light must travel in a straight line.
Light must enter a person's eye in order to see.
Nature of Science Learning Goals
Scientists change their ideas based on observations.
Scientific knowledge is developed by people.
