Young Engineers at the Lakeland STEAM center engage in STEM practices all the time. In the STEAM Explorers program 3rd and 4th graders planned and carried out investigations on how different materials react to the upward draft in their home-made wind-tunnel. They used different materials and speeds on the fan to test their wind-tunnel.
Engineering investigations are conducted to gain data essential for specifying criteria or parameters and to test proposed designs. Like scientists, engineers must identify relevant variables, decide how they will be measured, and collect data for analysis. Their investigations help them to identify the effectiveness, efficiency, and durability of designs under different conditions.
