This exercise is a enjoyable introduction to chromatography whereas studying concerning the totally different planets in our photo voltaic system.
The concept is that kids create every planet utilizing filter paper whereas serious about the scale and color of every one.
It’s unimaginable to get the scale comparisons proper because the distinction, in actuality, is so huge, however you can also make some planets smaller than others.
Filter Paper Planets
You’ll want
Felt tip pens ( not everlasting )
Water
Tray
Directions
Select a planet from the photo voltaic system and select colors to make use of to make it.
Draw small circles of color on the filter paper.
Fastidiously drip water onto every circle utilizing a pipette.
Watch as the colors unfold out. It is best to see some separation of every ink, displaying its constituent colors.
Cling the filter papers as much as dry after which reduce to dimension.
WHAT IS CHROMATOGRAPHY?
Chromatography is a scientific approach used to separate mixtures.
On this exercise, the totally different color inks in every felt tip journey at totally different speeds by way of the filter paper and so separate. Darkish color inks normally have extra totally different colors than lighter colors.
This exercise isn’t ultimate for seeing the separation of the ink however appears to be like good, and the colors blur collectively to seem like a planet.
If you wish to study extra about chromatography, arrange an investigation utilizing only a small dot of every color felt tip on the backside of a strip of filter paper and grasp it so simply the underside sits within the water and watch as the colors separate as they transfer up the paper.

Extra science for youths
Attempt one in every of my different area science experiments. You’ll be able to design, construct and check rockets, study asteroids and meteorites and plenty extra.
Stroll the photo voltaic system by cutting down the huge distances concerned!
