Science Sunday: Identifying footprints in the mud

how to identify the footprint in the mud

A few weeks ago when the kids were playing in the mud we found some footprints, or something odd in the mud.

Which led to the discussion of who could have left that.  That’s when I came up with my brilliant idea, which might or might not of ruined one of my plastic bowls.  I made a small batch of plaster of paris and poured it over the print.

But, I’d made too much, so I wandered around the yard pouring it into anything that vaguely looked like a footprint.  About 10 minutes later, thanks to the Texas heat, they were all dried up.

After much discussion about the different molds we had, we decided one was Mac’s footprint, that mystery was solved.  Another was from a child’s tennis shoe, next one solved.  A third was the impression from digging in the mud with fingers.  The others we could never successfully identify.

Do you ever find unidentified footprints in your yard?  Later I found an alphabet animal footprint chart which would have been helpful at the time.

 

 

 

Let’s see what others did this week:

Each week I’m spotlighting a few posts that were shared previously.  Many posts get linked up later in the week and they don’t always get as many clicks as they deserve, so I’m trying to spotlight a few posts every week.

 

I love Homegrown Learners incorporation of music and science into one to make a water xylophone

All Things Beautiful shared part 3 of their homemade terrarium, I’m storing this away for when we study botany.

My Joy Filled Life shared their homemade rockets to go with their astronomy studies.

 

Kathy’s Cluttered Mind shared their bug specimen board (no bugs were harmed in the making of it).
