Maryland Standards for Fourth Grade Science

MD.1.0. Skills and Processes: Students will demonstrate the thinking and acting inherent in the practice of science.

1.D.3.b. Investigate and describe that seeing how a model works after changes are made to it may suggest how the real thing would work if the same were done to it.
1.D.3.c. Explain that models, such as geometric figures, number sequences, graphs, diagrams, sketches, number lines, maps, and stories can be used to represent objects, events, and processes in the real world, although such representations can never be exact in every detail.
1.D.3.d. Realize that one way to make sense of something is to think how it is like something more familiar.

MD.2.0. Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.

2.A.2.a. Investigate and describe how weathering wears down Earth's surface: Water; Ice; Wind.
2.A.2.b. Cite evidence to show that erosion shapes and reshapes the earth's surface as it moves from one location to another: Water; Ice; Wind.

2.B.2. Earth History: Recognize and explain that fossils provide evidence about the plants and animals that lived long ago and about the nature of the environment at that time.

2.B.2.a. Recognize and explain that the remains or imprints of plants or animals can become fossils.
2.B.2.b. Describe the physical structures of an animal or plant based on its fossil remains.

2.D.1. Astronomy: Identify and describe the variety of objects in the universe through first-hand observations using the unaided eye, binoculars or telescopes or videos and/or pictures from reliable sources.

2.D.1.b. Identify the sun as the Earth's closest star.
2.D.1.c. Recognize that stars are like the sun, some are smaller and some larger.

2.E.2. Interactions of Hydrosphere and Atmosphere: Recognize and describe that each season has different weather conditions

2.E.2.a. Describe different seasonal weather conditions using data collected from weather instruments, models or drawings.
2.E.2.c. Compare average daily wind speed and direction during different seasons.
2.E.2.d. Compare average daily precipitation during different seasons: Amount; Type.

MD.3.0. Life Science: The students will use scientific skills and processes to explain the dynamic nature of living things, their interactions, and the results from the interactions that occur over time.

3.A.1. Diversity of Life: Explain how animals and plants can be grouped according to observable features.

3.A.1.a. Observe and compile a list of a variety of animals or plants in both familiar and unfamiliar environments.
3.A.1.b. Classify a variety of animals and plants according to their observable features and provide reasons for placing them into different groups.
3.A.1.c. Given a list of additional animals or plants, decide whether or not they could be placed within the established groups or does a new group have to be added.
3.A.1.d. Describe what classifying tells us about the relatedness among the animals or plants placed within any group.

3.D.1. Evolution: Explain that individuals of the same kind differ in their characteristics, and sometimes the differences give individuals an advantage in surviving and reproducing.

3.D.1.a. Describe ways in which organisms in one habitat differ from those in another habitat and consider how these differences help them survive and reproduce.
3.D.1.b. Explain that the characteristics of an organism affect its ability to survive and reproduce.

3.E.1. Flow of Matter and Energy: Recognize food as the source of materials that all living things need to grow and survive.

3.E.1.b. Describe what happens to food in plants and animals: Contributes to growth; Supports repair; Provides energy; Is stored for future use; Is eliminated.
3.E.1.c. Identify the things that are essential for plants to grow and survive.

3.F.1. Ecology: Explain ways that individuals and groups of organisms interact with each other and their environment.

3.F.1.a. Identify and describe the interactions of organisms present in a habitat: Competition for space, food, and water; Beneficial interactions: nesting, pollination, seed dispersal, oysters filtering as in the Chesapeake Bay, etc.; Roles within food chains and webs: scavengers, decomposers, producers, consumers.
3.F.1.b. Explain that changes in an organism's habitat are sometimes beneficial to it and sometimes harmful.

MD.4.0. Chemistry: Students will use scientific skills and processes to explain the composition, structure, and interactions of matter in order to support the predictability of structure and energy transformations.
