Curriculum: Water is an essential liquid for all living things and flows downhill. Its movement (flow) can be controlled and directed through engineering.

Note to caregivers before watching:

Water in liquid form always tries to flow downhill.
Water molecules like to stick together. They almost act like magnets: you can see this in the “exploring water molecules” activity below. When you put 2 waterdrops close together on wax paper, they will pull together into one bigger water drop. This is called cohesion —a force when 2 molecules of the same substance are attracted to each other.
Water also likes to stick to some materials more than others. Sometimes scientists call materials hydrophobic, meaning they repel or push away water. Or materials can be hydrophiles, meaning they attract or pull water toward them. When water sticks to a different material, this is called adhesion.
A hydrologic engineer is someone who designs and builds systems to manage and control the movement of water.
When your child is exploring and having fun, you might pick 1 or 2 of the science vocabulary words to introduce- to help explain what is happening. Vocabulary is best learned during a hands-on experience when the meaning of the word is being observed and your child is curious about it.

Before watching:

Ask: Is there water in the room are you in?
- If so, how did it get there?
- If not, why do you think there is no water?
What has been engineered to help water move from one place to another (sink faucet, cup)?
Say to the child(ren) “Let’s watch Mecha Builders to find out how the Mechas use engineered materials to move water.”
