From cell membranes in Entry Level Science to turgidity in A Level Biology, using potato and salt solution is a tried and tested investigation amongst biology teachers and students.
Your students are unlikely to have access to test tubes, cork borers or measuring cylinders at home, but with some creativity this investigation can be adapted for remote learning.
Fundamentally, all that is required is access to some plant tissue (carrot, courgette and beetroot all work well) and a solution. There are so many possible variables within this practical that it lends itself brilliantly to students designing their own investigation. They could consider:
Having access to only limited equipment encourages students to think outside of the box and apply their understanding in unfamiliar contexts, such as:
This investigation can be linked to a wide range of scientific skills including:
If using vegetables does not appeal to your students, perhaps a gummy bear alternative may spark their imagination.
