Unit 2 – Vocabulary

Yay! Now that we have completed Unit One and know the basics of environmental science, we can jump right into learning about water. If you haven’t checked out the “About me” page, I’d recommend you do that now. This website’s goal is to help you teach your students or children environmental science in sequential order with affordable STEAM (Science, Technology, Engineering, Art, and Math). Before starting this unit, review the importance of water with your students, so they know why we care about water. 

If you are teacher going back and forth between in person and distance learning use these Matching Google Slides to help. 

Water is the most necessary part of life. There is no life without water. This unit will focus on different aspects of water, but I want to start with why water is necessary for life. We cannot live longer than three days without water. It is essential for all life on Earth, not just humans. The first animals to ever live started in water. No creatures or plants can live on a planet without water, and few creatures can live on a planet with polluted and dirty water.



Remember to do a vocabulary game at the start of the unit.
