Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] JOAN CARTAN-HANSEN, HOST: You know we use the wood from trees to build things like houses.
But we use parts and by-products of trees to make lots of different things.
Aspirin was originally produced from willow bark.
The cork that seals some wine bottles.
it comes from the bark of cork trees.
And the spice cinnamon comes from cinnamon tree bark.
Real maple syrup is made from the sap of maple trees.
And chewing gum was also once made from tree sap.
We take trees and turn them into wood pulp, and when we do that, we get cellulose and a natural glue called lignin.
Lignin is used to make paints, dyes, plastics, and fertilizer.
And we use cellulose in clothes, rocket fuel, lipstick, even toilet seats.
And that wood pulp makes paper products like paper towels, napkins, and toilet paper.
which is handy because if you have toilet paper, You probably need a good toilet seat.
And it's all thanks to trees.
For more information about trees, check out the Science Trek website.
