Have a space in your classroom that enables creation, movement, or students applying what they learn to make a new product. How are your classroom expectations established? What does student responsibility look like in your room? Do you have rules that allow for student independence? The classroom culture is similar to environment but this is about how you are managing your space in a healthy way with rules and expectations. Environment is about the physical space, this is about how you create/build the "culture" in your room. Consider your room as a mini-island. This is your world and Utopia.
