You are responsible for your own sleeping gear. Bring a tent, a sleeping bag, a thermarest, a tarp, etc; whatever you need to remain comfortable regardless of the weather (see notes on climate below).
Breakfast and dinner are provided during the week-long intensives, bring snacks for lunches and between meals.
During the Summer Immersion Program you are responsible for all your own food and cooking ware. Bring enough food/snacks so that you don't need to run to town too often. It may be useful for you to also bring containers/coolers to store your food in. Bring some cookware that can stand being used on open fires/coals (like cast iron), as well as a plate/bowl and utensils.
