We have three The Search for Dark Matter materials kits. Each is a complete unit that will work for multiple classes; you should only request one. (Check availability below)
On the calendar, mark each day of your request. Your end date must be the date that you expect the kit will reach Sanford Lab on its return trip. You will be responsible for kit return.
In order to minimize shipping charges on both ends, please request the kit that fits the size of your largest class, if available.
