We are exploring magnets here in kindergarten! We sorted objects between magnetic and not magnetic. I wanted the kids to be able to glue down their sort to display in the hallway. You could use tape or regular glue, but in the interest of time I opted for a glue gun. This SUPER cool temp glue gun (you have to buy special glue sticks but they are not expensive) eliminates the worry over burns! But like I said, tape works too. We have some magnet sorting in our science station
