Infinity Images

1. Place the infinity mirror in front of your child.
   1. Allow them to observe and look in the mirror.
2. Ask your child to make observations about the mirror.
   1. Child should see a repeated pattern.
   2. The pattern should get smaller as it fades into infinity.
3. Ask your child:
   1. Does the pattern end?
      1. If so, why does it end?
      2. If not, why does it not end?
   2. The pattern continues, however, the light source is so far away it can no longer be seen.

1. Conduct research on stars with your child:

a. They produce light

b. Locations in the universe

c. Our sun is a star.

2. Provide opportunities for child to explore a light source from varying distances.

a. This may include:

i. A flashlight from different distances in the room

ii. Video of a train approaching at night

iii. Video of a plane taking off.

b. Have child identify and discuss what they notice about the light and object as they move closer and further away.

c. Support the discussion with reflective questioning.

1. Ask the question:

a. Is the apparent brightness of our sun and stars due to their relative distance from earth?

b. Ask child to provide evidence to support their answer.

2. Child should provide a method of explanation of their choice and use the infinity mirror, discussion, and research to support the claim.

a. Methods of explanation can include a presentation, poster, experimental observation/lab findings, drawings, 3D structure, etc.

NGSS CONNECTION:

4-PS4-2. Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

5-ESS1-1. Support an argument that the apparent brightness of the sun and stars is due to their relative distances from the Earth.
