ABOUT SCIENCE Instruction
using real-world science…a sample lesson
In chemistry, students learn about the concepts of molecular structure and polarity, and how these factors influence physical properties such as water solubility. Now…you could give notes on these concepts and have the students verify what they wrote down in the lab… or you catch the students’ interest with a story and build it from there! Around the time of this lesson, a conspiracy theory related to COVID vaccines went viral. High schoolers love that stuff - but it’s junk science! So I thought of a way to connect the REAL science behind the theory with my lesson objective.
Go ahead and click the button. Then ask yourself…does this lesson present students with a problem? Does the problem generate questions that can be modeled and tested out in the lab? Does it yield data that can be analyzed? Do the results lead students to the concept of “likes dissolve likes”? Does it go further and apply the concept to a current real life problem and the engineering design used to solve it? If the answer to these questions is “yes” then you have a lesson that meets all the NGSS criteria…and the best part is that the students will use critical thinking skills to figure the concept out on their own!
