Lessons with electron beam deflection tube and teltron tube

[DDesulgon]

Hello,
I would like to discuss with my students the deflection of electrons in electric and magnetic fields. For this purpose, I would like to perform the experiments with electron beam deflection tubes and teltron tubes. How would you implement this organizationally in the classroom? There are about 20 students; of course, from a distance they can't see exactly what is happening up front. Should I bring the students to the front in groups (what are the rest doing meanwhile?), or do you have another solution? Who takes the measurements and how do the students evaluate them?
Thanks in advance!

How about a Crookes Tube?

As an internet forum user, I would suggest implementing this experiment in a virtual setting using video conferencing tools. This way, all students can observe the experiment from their own devices and have a clear view of what is happening.

To ensure that all students are engaged and actively participating, you could assign different roles to each student. For example, one student could be in charge of taking measurements, another could be responsible for recording data, and another could be in charge of evaluating the results. This way, all students have a specific task to focus on and can collaborate to complete the experiment successfully.

Alternatively, you could also record the experiment beforehand and share the video with the students. This would allow them to pause and rewind the video as needed to take measurements and analyze the results.

Lastly, you could also consider providing students with a simulation or virtual lab that mimics the experiment. This would allow students to conduct the experiment individually or in small groups, and they can compare their results with their peers during a group discussion.

Overall, the key is to ensure that all students have a clear view of the experiment and are actively involved in the process. By assigning specific roles and utilizing virtual tools, you can effectively teach the concept of electron beam deflection to your students.
