Art meets Science: Microbe Drawings 101

What can I use if I don't have a clean microscope slide, cover slip, or microscope?

Use the clear shallow dish from the materials as your viewing base, a clean jar lid or a square of clear plastic in place of a cover slip, and a handheld magnifying glass instead of a microscope to complete the steps of putting a drop on a surface and looking for shapes.

My sample looks blurry or has air bubbles under the cover slip so I can't see details — what should I try?

When you put the drop on the slide or into the dish, blot excess liquid with the paper towel, lower the cover slip at an angle to push bubbles out, or switch to a thinner specimen like a single onion skin as described in the collection step to improve clarity.

How can I change this activity for younger children or make it more challenging for older kids?

For younger children, have an adult handle the sample, slide/dish and cover slip steps while the child focuses on sketching, tracing with the black pen, coloring, and labeling three parts, and for older kids let them collect samples with supervision, use a phone or digital microscope, add finer detail with the sharper pencil, and write longer observations beyond the required sentences.

What are some ways to extend or personalize the finished microbe drawing beyond sharing it on DIY.org?

Create a mini 'microbe field guide' by collecting multiple colored and labeled drawings from different samples, include each drawing's 'where you found the sample' sentence and 'safety rule' sentence, then bind them into a booklet or make a slideshow to upload to DIY.org.
