Of all the chapters i have learned about in science my favorite part of the Weather and Climate (Earth's Atmosphere) section was when we learned about earths winds. My favorite part of the Weathering and Erosion section was when we made the podcasts with our groups. My favorite part of the Earth's Waters section was the supply and demand experiment. My favorite part of the Astronomy section was learning about black holes. Finally, my favorite part of the Geology section was learning about different types of rock hardness and how to find how hard a rock is. in all my favorite section for the hole year was the Astronomy section because space and whats in it has always astounded me.

Water cycle

the water cycle is a continuous cycle. a puddle might be sitting on the street one fin sunny day and within a few hours the puddle will have evaporated then as the water vapor rises it cools and condenses into clouds. after the water vapor has condensed it will then start to fall back as rain and become a puddle again.
