Does your kiddo like things on the yucky side? Take advantage of the gross factor and make your at-home science lessons a little extra icky with the following science experiments for kids. Whether it’s making goo, growing mold or learning about germs, these fun and simple science experiments will have your little lab rat saying, “Ewww!” Click through the slideshow to get the goop.

Have a Gooey Peep War

This one is a little more gooey than gross, but we think it makes for great afternoon science. Grab some ghost peeps to get in the spirit of the season or use those leftover birds and bunnies you never actually tossed. Arm your Peeps with toothpicks, then pop them in the microwave to see who wins the joust. If your kids don't know what happens when marshmallows get microwaved, have them write their hypotheses beforehand (and/or bet on the winner!) Need inspiration? Watch a full-blown Peep jousting tournament here.
