During respiration, food molecules react with oxygen producing carbon dioxide and water. Bonds are broken and formed, and there is a net transfer of energy in process. [MS-LS1-7][HS-LS1-7]
But, how can you help students understand that ALL living things respire? With the Wireless Carbon dioxide sensor, some peas, and some sampling bottles, they can collect carbon dioxide data as evidence! They can quickly analyze the data for trends in SPARKvue, and create their own inquiry experiments!
