Diocesan Standard - Grade 2 - Science

1 - Earth?s Changing Surface
- 1.1 - Obtain and communicate information that water exists in different forms within natural landscapes and determines the variety of life forms that can live there.
- 1.2 - Investigate how wind and water can move Earth materials from one place to another and change the shape of landforms.
- 1.3 - Design, test, and refine a technological solution that would prevent changes to land caused by wind or water and communicate the solution using sketches, drawings, or physical models.
- 1.4 - Obtain and share information about how landforms provide homes for living things.
2 - Structure, Properties, and Interactions of Matter
- 2.1 - Evaluate natural or designed objects to explain how the properties of the materials suit different purposes.
- 2.2 - Collaborate with others to design an object built from a small set of pieces to solve a technological problem.
- 2.3 - Provide evidence that some changes caused by heating or cooling can be reversed and some cannot.
- 2.4 - Measure and compare the physical properties of objects.
3 - Interdependence of Organisms and Their Surroundings
- 3.1 - Construct a representation in which plants and animals depend on their environment and each other to meet their needs.
- 3.2 - Ask questions to clarify ideas about how plants may depend on animals for pollination or to move their seeds around.
- 3.3 - Plan and carry out investigations to test whether plants from different settings have different needs for water, sunlight, and type of soil.
- 3.4 - Observe and compare the many kinds of living things that are found in different areas.
- 3.5 - Analyze a representation of a particular habitat showing the locations and shapes of both land and water features of that habitat and communicate how the land and water support animals and plants.
- 3.6 - Construct an explanation about the effect of environmental changes ? whether slow or rapid ? on the survival of plants and animals that live there.
- 3.7 - Obtain and communicate information that some kinds of animals and plants that once lived on Earth are no longer found anywhere, although others living now may resemble them.
4 - Force and Motion
- 4.1 - Investigate the effect of pushes and pulls in different directions on the resulting motion of objects.
- 4.2 - Investigate the effect of pushes and pulls of different strengths on the resulting motion of objects.
- 4.3 - Construct an explanation for why an object subjected to multiple pushes and pulls might stay in one place or move.
- 4.4 - Analyze data to determine the relationship between friction and the motion of objects.
- 4.5 - Analyze data to determine the relationship between friction and the warming of objects.
- 4.6 - Develop and share a design solution to reduce friction between two objects.
- 4.7 - Plan and carry out investigations of how the change in motion and/or shape when objects touch or collide is related to the speed of the objects.
