Magnetic Slime recipe and Tutorial!

It’s Slime day! Slime Day!! Magnetic Slime Day! Magnets! We need some slime-loving, magnet hoarding kiddos for today’s lesson!

Today, we’re making magnetic slime, which is amazing, and then we’re using that slime to visualize the field lines that surround magnets. Which is even more amazing!

We’ve got the Zoom classroom open from the beginning for Evan-troubleshooting, chatting and project sharing. Come join us there or on Youtube.

See you all very soon!

Dr. Erica and Evan

PS We saw some AMAZING pendulums yesterday!!!
