The Vernier Go-Direct probes connect via bluetooth or USB to smartphones, tablets, and computers allowing students to collect real-time data directly into free graphing and analysis software. Students can design experiments to test rates of photosynthesis of various plant species under a wide range of conditions. As the producers photosynthesize, they use carbon dioxide in the air to produce sugar. These probes measure the carbon dioxide levels in the closed system allowing students to see changes by examining the data. As students add consumers to the system, they are able to monitor the changes in carbon dioxide levels indicating cellular respiration is taking place. These closed-system models illustrate the interdependence of poducers and consumers in ecosysems, and reveal the consequences when part of the system becomes out of balance. Additional activities can include manipulating the carrying capacity of a system and its affect on populations. While I am purchasing the probes primarily for high school biology classes, chemistry students may use the probes to illustrate limiting reactants and stoichiometry. Middle school students can also use the probes to explore the interdependence of producers and consumers in ecosystems (part of middle school state standards). These activities help fulfill Louisiana Life Science Standards (HS-LS1-2,5,7; LS2-1,4) as well as give the students multiple opportunities to design inquiry-based labs and model real-world living systems. In addition, students will gain practice collecting and analyzing data, creating and interpreting graphs, and drawing conclusions from quantitative data.
