Science Worksheets and Study Guides Third Grade. What are Ecosystems?

The resources above cover the following skills:

Motion and Stability: Forces and Interactions
Students who demonstrate understanding can:
Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion.
From Molecules to Organisms: Structures and Processes
Students who demonstrate understanding can:
Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
Biological Evolution: Unity and Diversity
Students who demonstrate understanding can:
Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
Earth’s Systems
Students who demonstrate understanding can:
Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.
Obtain and combine information to describe climates in different regions of the world.
