My students need 12 current probes in order to participate in an electroplating lab during the electrochemistry unit.
I am very fortunate to teach the students of this community. They are motivated, inquisitive, and really enjoy collaborating when given a project. Over the past year, parents have generously donated towards my vision of introducing STEM-based chemistry and biology labs involving amazing technology that is used to gather data.
The students appreciate the opportunity to use the STEM lab equipment because it allows them to use technology while collaborating and using critical thinking to produce results which help prepare them for the future.
This year I am excited to teach electrochemistry which is involves principles that are found in AP physics and chemistry. Many of my students will be enrolled in either of these courses next year so this is a perfect introduction. We need 12 current probes for this amazing STEM based lab.
In this experiment, the students will use the current probes to conduct, observe, and measure the process of electroplating.
This process is used to deposit a layer of metal, such as chromium, copper, or gold, onto another metal. will prepare an electrochemical cell by using a copper strip as the cathode (positive terminal) and a brass key as the anode (negative terminal). The electrodes are immersed in a solution containing acidified copper (II) sulfate. As they apply a potential to the electrodes, the students will be effectively transferring Cu atoms from the anode to the surface of the brass key.
