In the first trimester:

• Students engage in the Water and Climate unit. How is water involved in weather, and are weather conditions the same around the world and throughout the year? Students explore the properties of water, the water cycle, and interactions between water and other earth materials. Students learn how humans use water as a natural resource. Students engage in science and engineering practices while investigating water, weather, and climate, and explore the crosscutting concepts of patterns; cause and effect; scale, proportion, and quantity; and systems and system models. 

In the second trimester:

• Students will be using the Engineering Design Process to solve engaging problems.

In the third trimester:

• Students observe, compare, categorize, and care for a selection of organisms in the Structures of Life unit. Students engage in science and engineering practices to investigate structures and behaviors of the organisms and learn how some of the structures function in growth and survival. Students look at the interactions between organisms of the same kind, among organisms of different kinds, and between the environment and populations over time.
