100 Days of Science-- #81 Mushroom Spores

I've been searching high and low for some easy and quick science experiments to try with my boys this summer.  I really want to finish up our 100 Days of Science Challenge with them but I did promise them a summer break this year so I knew I had to find some simple and fun projects they'd be willing to do with me.  Learning about mushroom spores fell so nicely into the easy and quick category!

We bought a Portobello mushroom for this experiment and just removed the stem. We placed the cap of the mushroom and the stem facedown on two separate pieces of white paper and left them there for a few hours.

It didn't make much of an impression or mark like I thought it was supposed to so I trimmed just a tiny bit more off and we put the mushroom face down on another corner of the page and left it overnight.

The next morning we could see lots of mushrooms spores!

    1. I am all about easy; especially in the summer.

  2. This reminds me of a mushroom project my mom embarked on. She visited a mushroom farm and brought home a mushroom growing kit with the intention to grow her own mushrooms. But her experiment turned into a mushroom nightmare! Mushrooms started to sprout on any/every thing that was made of wood - clothes hangers, pegs, chopping board, clogs, chairs, chopsticks etc - anywhere wooden the spores landed on. So be careful when you're handling mushroom spores!

    1. Oh my goodness! I can't even imagine! We threw our paper away after snapping photos and that was a good week ago... wonder if there are mushrooms growing in the dumpster!

  3. Love hands-on learning. Thank you for sharing at Party In Your PJ's!

  4. Great project :)

    Thanks for sharing at The Wednesday Blog Hop a few weeks ago.
