- Marbles (what we’ll pretend are spores)
- Cutting board or other flat surface
- “Bio-Glues” (peanut butter, e.g)
- Kitchen sink
- Pick a type of bio-glue, and use it to stick your marble (the spore) to the cutting board. You should only use a small amount of glue, roughly the same amount of glue as the size of your marble.
- Once the marble is stuck, put the cutting board under the faucet, so that water runs over the marble. Using the timer, see how long it takes to remove the marble from the surface.
- Repeat your experiment, but change things up! What makes the marble stick better or worse? Here’s some suggested variations to try: - Different amounts of glue - Different kinds of glue - Changing position of the glue (front/back, top/bottom) - Attaching the glue underwater
Spores produce a “glue” that allows them to stick to surfaces underwater. These glues are natural, unlike Elmer’s or other man-made glues that are made from petroleum. To imitate spores, we’ll limit ourselves to bio-glues, or glues that are made from natural stuff, like food (peanut butter, molasses, etc.)
