Here comes the why questions!

“What’s a rainbow?” asks Andrew.

‘A rainbow is an arc of colors that appear in the sky when it is raining in one part of the sky and sunny in another. A rainbow forms when the sun shines through droplets of water while it’s raining or was recently raining. How does that happen? Sunlight comes from the sun. The sun is located in space. Sunlight has to travel through space and to earth, it does that in what scientists call wavelengths. Wavelengths are actually different colors. As they are traveling they blend together and form white light. When the wavelengths pass through droplets of water (rain) they separate and appear as the colors of a rainbow. 

Do you want to try to make a rainbow at home? 

Try this fun rainbow experiment in the summertime.

Step 1: Standing with your back to the sun. How do you know your back it to the sun? Stand where you feel the heat of the sun on your back and look forward. If your back is getting warm and you can look without squinting your eyes then your back is to the sun

Step 2: Take a water hose and spray it in front of you keeping the sun behind you. Watch what happens. A rainbow should form.’ (Source) 

“I remember finding a video online a few months ago about rainbows,” says Olivia. “Let me see if I can find it again. There it is - How rainbows form and what shape they really are.” 

Olivia turns her phone in their direction and then presses the play button.

When the video ends Ashley asks Andrew if he liked it. Andrew nods his head and now it’s time for some why questions!
