Massachusetts Curriculum Frameworks

MA.3-ESS. Grade 3: Earth and Space Sciences
ESS2. Earth’s Systems
3-ESS2-1. Use graphs and tables of local weather data to describe and predict typical weather during a particular season in an area.
3-ESS2-2. Obtain and summarize information about the climate of different regions of the world to illustrate that typical weather conditions over a year vary by region.
MA.3-LS. Grade 3: Life Science
LS1. From Molecules to Organisms: Structures and Processes
3-LS1-1. Use simple graphical representations to show that different types of organisms have unique and diverse life cycles. Describe that all organisms have birth, growth, reproduction, and death in common but there are a variety of ways in which these happen.
LS4. Biological Evolution: Unity and Diversity
3-LS4-3. Construct an argument with evidence that in a particular environment some organisms can survive well, some survive less well, and some cannot survive.
3-LS4-4. Analyze and interpret given data about changes in a habitat and describe how the changes may affect the ability of organisms that live in that habitat to survive and reproduce.
MA.3-PS. Grade 3: Physical Science
PS2. Motion and Stability: Forces and Interactions
3-PS2-1. Provide evidence to explain the effect of multiple forces, including friction, on an object. Include balanced forces that do not change the motion of the object and unbalanced forces that do change the motion of the object.
