Take a look at this Grade 3.

The Lawn Mower

Today in class the Grade 3 learned about writing in their own words. This paragraph came from Enchanted Learning.com. It is been pasted here to show the original source:

LAWN MOWERThe first lawn mower was invented in 1830 by Edwin Beard Budding. Budding (1795-1846) was an engineer from Stroud, Gloucestershire, England. His reel mower was a set of blades set in a cylinder on two wheels. When you push the lawn mower, the cylinder rotates, and the blades cut the grass. Budding patented his lawn mower on August 31, 1830. Before his invention, a scythe was used (or sheep or other grazing animals were allowed to graze on the grass). The first reel lawn mower patent in the US (January 12, 1868) was granted to Amariah M. Hills, who formed the Archimedean Lawn Mower Co.

As a class we wrote this:

Edwin Budding invented the first lawn mower. He came from England. The lawn mower was inspired by a sheep. The lawn mower was invented in 1830.

Enchanted Learning (2007) http://www.enchantedlearning.com/inventors/indexl.shtml

All students will need to use the following guide when they are researching about inventions:

1. The name of the invention
2. Who invented it?
3. What inspired the invention?
4. How does it work?

My question for Grade 3 is 'How does the lawn mower work?'.
