Fourth Grade Inventors


We have been busy with our inventions and also trying to learn about our state government. The end of the year is approaching and I am happy to see the progress the students have made. The government test will be on Wednesday so don't forget to review over the weekend.

The students did a tremendous job on the six-step process of design. They created some very creative inventions to solve a variety of problems. Emma Z. and Megan P. designed two inventions to help horses. Emma created rubber horseshoes to prevent ruts in the road. Megan decided to make a type of blanket to cool the horses down when it's warm. She used a science experiment and mixed baking powder, cream of tartar, and water to cause a chemical reaction. This made the temperature of the water drop and cooled the horses backs. Everyone did a great job!
