Making Paper by Trish Puharich
“Making Paper” describes how a class turned waste paper into an interesting, new kind of paper.
WALT to find out how the students in the reading made recycled paper.
WALT to learn the steps involved in turning used paper into new paper.
WALT to identify the materials and tools needed to make recycled paper.
Why Should We Recycle Paper?
1. Saving Trees:
Paper is made from trees, which are cut down and turned into pulp to make new paper. When we recycle, we can use old paper to make new paper instead of cutting down more trees. This helps us protect forests and the animals that live there.
Trees also absorb carbon dioxide and give us oxygen, which we need to breathe. So, by recycling, we are helping to keep our air clean!
2. Saving Energy:
Making new paper from recycled paper uses less energy than making paper from fresh wood pulp. This means less fuel is burned, and less carbon dioxide is released into the atmosphere, which helps reduce pollution and global warming.
3. Reducing Waste:
If we didn’t recycle, all the old paper would end up in landfills. When paper decomposes in landfills, it produces methane gas, which contributes to climate change. Recycling helps reduce this waste.
How Recycling Paper is Related to Science
Every time we recycle a piece of paper, we're helping protect trees, save energy, and keep our environment clean.
Chemistry: When we add water to paper to make pulp, we're using chemistry to break down the materials. Adding chemicals during deinking helps remove things like ink and glue, making the pulp cleaner.
Physics: We use screens, pressure, and heat to filter, press, and dry the paper. These are all physical processes that change the shape and texture of the pulp, turning it back into sheets of paper.
Biology: By recycling, we help save natural resources, reduce energy use, and minimize waste. This science teaches us how to take care of our planet and make it healthier.
