Earth Day Absorption Science

Water is a fantastic “chemical” to do science experiments and investigations with.  I love this easy water absorption activity, especially for the littlest tots.   Easy to set up with cotton make-up pads, some water and droppers.  Using blue and green water, this makes a perfect Earth Day STEAM activity.

Here’s what you’ll need to get started:

  • Small tray/plate or cookie sheet
  • cup of blue water
  • cup of green water
  • dropper
  • Round cotton pads

Show your little one a picture of the Earth.  We spent some time talking about our planet and where we live on the planet, that the blue was oceans, the green and brown was the land and the white were the clouds.

Next, I gave them a cup of green water, blue water, dropper and a cotton pad and told them to drip the colored water onto the pad to create their own Earth.

The tots LOVE droppers!

The youngest ones dipped their pads in the water or dumped the water onto their pads.

The older ones were particular about where to place the green and blue drops.

They were so proud of their Earths!

The Science Behind the Activity:

I love using droppers whenever possible as it is a great way to strengthen muscles in preparation for learning to write AND it develops fine motor skills, both of which are vital as pre-writing skills begin emerging.  It’s also a great way to watch how water gets “sucked up” by the cotton pad and to introduce big words such as “absorb” and absorption” to their expanding vocabulary.
