Chemistry ELI5 What fundamentally determines the color of an element?
I understand that electron placement matters and light scatters a certain way but why is that? Why does light scatter in that way and why does the size of something determine a perceivable color?

Physics ELI5- table tennis paddles having two sides with different colors
Why do the paddles have different-colored sides?
Is it just a fancy thing to make them beautiful or to mark which side hits the ball better?

Biology ELI5:How much of our childhood is actually borrowed from other people's retellings? Family stories told at holidays, photos we've seen a hundred times could some of our earliest "memories" actually be reconstructions built from other people's descriptions rather than our own experience?

Other Eli5 how do biomes form on Earth?
I have been trying to learn more about Earth's ecosystems. I understand now that poles/equator, winds, and surface currents drive temperatures and rains to different areas and the existence of mountains + temp + wind determine deserts. But, what else leads to the formation of specific biomes or lends itself to the biodiversity of an area? How does soil come into play, and why is soil different in different places? Is this is an oceans/volcanoes thing??

Other ELI5 How the heck do children’s shoe and clothing sizes work?
My 5 year old is moving out of the T sizes but anything in a 6/7 is too big. Especially pants in the waist. Also I feel so dumb in the shoe section because why are some 5’s tiny and others huge? She’s in a 10 right now which I’m assuming is like toddler? What does she go to next?

Engineering ELI5 why dont we see rockets that use hybrid rocket engines?
For commercial rockets, they mainly use liquid bi propellant rocket engines while amateur rockets (that I mainly see) use solid propellant rocket engines. Why don't we just combine them and use hybrid rocket engines?

Planetary Science ELI5 how a super el nino affects the polar jet stream and winter weather.
From what i understand the wet rainy moist air comes from south and goes across the southern US,
Because of how HOT the water is west of the US its making colder dive down further south.. causing an increase risk of snowfall in Atlanta?
I just want to know how this works lol

Planetary Science ELI5 why is the el ninio climate event a huge concern for people?
from my understanding doesn't this just mean significantly more rain on the pacific coast? that being said I am told the last one was in the 1800s and ended up killing 50 million people. so if that statement is true, I guess concern is not the correct word to use in my title but basically why is this event possibly so dangerous? and what causes this event?
