learned about light years

Science

• The child has learned that a light year is a measure of distance, not time.
• They understand that a light year is the distance that light travels in one year, which is about 5.88 trillion miles.
• They have learned that light years are used to measure vast distances in space, such as the distance between stars and galaxies.
• They now know that objects that are farther away from Earth appear to us as they were in the past due to the time it takes for light to travel to us.

Encourage the child to further explore the concept of light years by conducting simple experiments at home. For example, they can measure the time it takes for light to travel short distances and calculate how far light would travel in a year based on that speed. They can also research famous astronomical objects and events that are measured in light years, such as the Andromeda Galaxy or supernovae, and create art or models to represent them.
