Georgia Grade 2 science standards

S2E2 Obtain, evaluate, and communicate information to develop an understanding of the patterns of the sun and the moon and the sun’s effect on Earth. a. Plan and carry out an investigation to determine the effect of the position of the sun in relation to a fixed object on Earth at various times of the day. b. Design and build a structure that demonstrates how shadows change throughout the day. c. Represent data in tables and/or graphs of the length of the day and night to recognize the change in seasons. d. Use data from personal observations to describe, illustrate, and predict how the appearance of the moon changes over time in a pattern.

Lessons: Light and Shadows (Why is my shadow long in the morning?) (partly)

S2L1 Obtain, evaluate, and communicate information about the life cycles of different living organisms. a. Ask questions to determine the sequence of the life cycle of common animals in your area: a mammal such as a cat, dog or classroom pet, a bird such as a chicken, an amphibian such as a frog, and an insect such as a butterfly. b. Plan and carry out an investigation of the life cycle of a plant by growing a plant from a seed and by recording changes over a period of time. c. Construct an explanation of an animal’s role in dispersing seeds or in the pollination of plants. d. Develop models to illustrate the unique and diverse life cycles of organisms other than humans.

Lessons: Plants and Seeds: What Does a Seed Need? (What does a seed need to grow?) (partly)

Practice: Plants and Seeds: What Does a Seed Need? workbook

S2P1 Obtain, evaluate, and communicate information about the properties of matter and changes that occur in objects. a. Ask questions to describe and classify different objects according to their physical properties. b. Construct an explanation for how structures made from small pieces (linking cubes, building blocks) can be disassembled and then rearranged to make new and different structures. c. Provide evidence from observations to construct an explanation that some changes in matter caused by heating or cooling can be reversed and some changes are irreversible.

Lessons: Test It, Choose It: Materials (What is it made of?, Which material keeps the rain out?, Which hat keeps the sun off?) (partly)

Practice: Test It, Choose It: Materials workbook · Kitchen Chemistry for Families workbook

S2P2 Obtain, evaluate, and communicate information to explain the effect of a force (a push or a pull) in the movement of an object (changes in speed and direction). a. Plan and carry out an investigation to demonstrate how pushing and pulling on an object affects the motion of the object. b. Design a device to change the speed or direction of an object. c. Record and analyze data to decide if a design solution works as intended to change the speed or direction of an object with a force (a push or a pull).

Lessons: Build It, Launch It (How does a rocket push itself into space?) (partly)

Practice: Build It, Launch It workbook
