Have students explore how the sun, Earth surface types, and water work together to affect the Earth and objects through discussion and multiple experiments in this SMARTBoard unit. Corresponding pdf worksheets are included in the paperclip tab. Website links are also included. (Some concepts are challenging, but I have done this with K classes for several years.)
Next Generation Science standards for Kindergarten are included on many of the pages.
