Algae are so small to be seen by naked eye. That means that we need a microscope.
Follow these instructions and you’ll be ready to discover a microscopic world!
1. Mix the sample, which is located in the fridge.
2. Add one drop of the sample (with a pipette) into the microscopic slide.
3. Cover the sample with a slide cover.
4. Use the microscope in order to see some algae. Do you know at which family do they belong (diatom, green algae, cyanobacteria)?
