Quantifying Gas Production With Carbon Dioxide and Oxygen Sensors

My students need oxygen and carbon dioxide sensors so that Biology students can do quantitative experiments about photosynthesis and cellular respiration, and Chemistry students can precisely measure gas production.

My Students

The students at my school are unique people who thrive in this small, close-knit environment. Because we are a small school, we can be much more flexible about meeting student needs when they are struggling or flying high. Engaging science experiments are a big part of this and teach much more than just the science content.

Many students who struggle with "book learning" shine when they get to do hands-on science projects.

Since many of my students' post-graduation plans don't involve college, it becomes even more important to emphasize skills that every student can carry with them. Labs are also the window to engaging students with content at whatever level is right for them.

My Project

Lab experiments are truly the way that students learn science. However, not all lab experiments are equally successful at promoting learning. In past years, I have attempted "non-tech" experiments related to photosynthesis and cellular respiration. Unfortunately, my students have struggled to get data that is consistent and precise enough for them to truly test various conditions. Rather than solidifying their understanding of the topics, these labs have left my students more confused.

My students have had much better success with labs in which we were able to use Vernier sensors, which is why I'm requesting these!

My students have had much better success with labs in which we were able to use Vernier sensors, which is why I'm requesting these! They will be used primarily in my Biology class to test how gas production during photosynthesis and cellular respiration varies under different conditions. We will also use them in Chemistry as another way to check and quantify the type and amount of gas produced in chemical reactions. In addition, my engineering students may use them to track carbon dioxide content throughout the day and check the affect of proposed solutions.
