Support an argument that plants get the materials they need for growth chiefly from air and water.
Ecosystems: Interactions Energy and Dynamics
Develop a model to describe the movement of matter among plants animals decomposers and the environment.
Matter and Its Interactions
Develop a model to describe that matter is made of particles too small to be seen.
Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating cooling or mixing substances the total weight of matter is conserved.
Make observations and measurements to identify materials based on their properties.
Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
Motion and Stability: Forces and Interactions
Support an argument that the gravitational force exerted by Earth on objects is directed down.
Use models to describe that energy in animals' food (used for body repair growth motion and to maintain body warmth) was once energy from the sun.
