I learned about three inventions and one inventor this week. The inventions are soda water, the weight scale, and the boring machine. The inventor’s name is Joseph Preistly. First, I learned about soda water. Soda water is water infused with CO2. It became the most popular with the British in the 1850s. Second, I learned about Joseph Priestley. He was born in England in 1733. He invented a new method of producing CO2 gas and he identified the process of photosynthesis. Third, I learned about the weight scale. The weight scale measures weight and allows you to read weight immediately. It is used in medicine, chemistry, food, and industries. Last, I learned about the boring machine. Boring machines make holes in solid metal. The boring machine made Watt’s engine possible.
