GIF of magnet being dropped down a copper pipe showing it slow down due to magnetic induction.

# data[].attributes.attachment_link.description
When a magnet falls it induces a current in the copper pipe. That current creates a magnetic field that opposes the changing field of the falling magnet, so the magnet is repelled and falls more slowly. It almost looks like it's floating through the pipe.

Storyline of light’s nature and how we use it to see and communicate.

# data[].attributes.attachment_link.readable_text
This first-grade unit on light starts with students exploring how many shapes they can see on different pieces of paper at various locations around their classroom when the lights are turned off. They are surprised to find that some of the shapes are not visible in these conditions. This leads students to start wondering about other phenomena related to seeing in the dark, which in turn leads to new questions and design problems related to how they can make their room completely dark.

What students figure out

By the end of the unit, students develop powerful ideas about the interaction of different materials with light, and its effects on what we see. These ideas include:

Objects can be seen if light is available to illuminate them or if they give off their own light; very hot objects give off light.

Some materials allow light to pass through them, others allow only some light through, and others block out all the light and create a dark shadow on any surface beyond them, where light cannot reach.

People can use light to communicate (send and receive information) over long distances.

A situation that people want to change or create can be approached as a problem to be solved through engineering.
