First up, Goggles
Safety's important! I don't plan to use anything stronger than vinegar, but I think it's important to form good habits. And, kids love the goggles and the autheniticity they add to the experience!
I got 10 of these, based on past attendance. If we need more, we'll order more.
Magnetic Wands
Lots of fun and great to have on hand for a variety of activities!
We purchased a set of 12 wands.
Set of Timers
So many uses in so many settings! These are great for working with younger kids because the buttons are big and it's easy to refer to them by color.
We have a set of 6 timers, as they're a bit more expensive than some things and most of my activities that use timers are done in groups
Thermometers
We have a set of 5 thermometers as I anticipate that any activity using them will be performed in groups. We can easily get more if the need arises.
