2.P1U1.1: Plan and carry out an investigation to determine that matter has mass, takes up space, and is recognized by its observable properties; use the collected evidence to develop and support an explanation.
2.P1U1.2: Plan and carry out investigations to gather evidence to support an explanation on how heating or cooling can cause a phase change in matter.
2.P4U1.3: Obtain, evaluate and communicate information about ways heat energy can cause change in objects or materials.
2.E2U1.8: Observe and explain the Sun’s position at different times during a twenty-four-hour period and changes in the apparent shape of the Moon from one night to another.
2.E1U1.5: Develop and use models to represent that water can exist in different states and is found in oceans, glaciers, lakes, rivers, ponds, and the atmosphere. 2.E1U1.4: Observe and investigate how wind and water change the shape of the land resulting in a variety of landforms.
2.E1U2.6: Analyze patterns in weather conditions of various regions of the world and design, test, and refine solutions to protect humans from severe weather conditions.
2.E1U3.7: Construct an argument from evidence regarding positive and negative changes in water and land systems that impact humans and the environment.
2.L2U1.9: Obtain, analyze, and communicate evidence that organisms need a source of energy, air, water, and certain temperature conditions to survive.
2.L2U1.10: Develop a model representing how life on Earth depends on energy from the Sun and energy from other organisms.
