Colorado State Standards for Science: Grade 4

CO.1. Students apply the processes of scientific investigation and design, conduct, communicate about, and evaluate such investigations.

1.1. Design, plan and conduct a variety of simple investigations (for example: formulate a testable question, state a hypothesis, make systematic observations, develop and communicate logical conclusions based on evidence) 32

1.2. Select and use appropriate tools and technology to gather and display (for example: graphs, charts, diagrams) quantitative and qualitative data related to an investigation (for example: length, volume, and mass measuring instruments, thermometers, watches, magnifiers, microscopes, calculators, and computers) 32

CO.2. Physical Science: Students know and understand common properties, forms, and changes in matter and energy. (Focus: Physics and Chemistry)

2.1. Objects have physical properties that can be measured (for example: length, mass, volume and temperature) 7
Suggested Titles for Colorado Science State Standard 2.1.

2.2. Measurable physical properties can be compared before and after effecting a change to verify a change has occurred and used to predict its outcome in similar circumstances\ 22

Suggested Titles for Colorado Science State Standard 2.6.

2.7. There are different types of forces (for example: gravity and magnetism) 6
Suggested Titles for Colorado Science State Standard 2.7.

2.8. Changes in speed or direction of motion are caused by forces 6
Suggested Titles for Colorado Science State Standard 2.8.

CO.3. Life Science: Students know and understand the characteristics and structure of living things, the processes of life, and how living things interact with each other and their environment. (Focus: Biology-- Anatomy, Physiology, Botany, Zoology, Ecology)

3.1. Each plant or animal has different structures and behaviors that serve different functions in growth, survival, and reproduction 97
Suggested Titles for Colorado Science State Standard 3.1.

3.2. Green plants need energy from sunlight and various raw materials to live, and animals consume plants and other organisms to live 16
Suggested Titles for Colorado Science State Standard 3.2.

3.3. Human body systems have basic structures, functions and needs (for example: digestive, respiratory, circulatory, skeletal, muscular) 45
Suggested Titles for Colorado Science State Standard 3.3.

3.4. There is interaction and interdependence between and among nonliving and living components of ecosystems (for example: food webs, symbiotic and parasitic relationships, dependence on rainfall, pollination) 84
Suggested Titles for Colorado Science State Standard 3.4.

3.5. Life cycles vary from organism to organism (for example: frog, chicken, butterfly, radish, bean plant) 97
Suggested Titles for Colorado Science State Standard 3.5.

3.6. Fossils can be compared to one another and to living organisms according to their similarities and differences 9
Suggested Titles for Colorado Science State Standard 3.6.

3.7. There are similarities and differences in appearance among individuals of the same population (for example: size, color, shape) 54
Suggested Titles for Colorado Science State Standard 3.7.

3.8. There are similarities and differences between organisms (for example: plants vs. animals, vertebrate vs. invertebrate) 111
Suggested Titles for Colorado Science State Standard 3.8.

CO.4. Earth and Space Science: Students know and understand the processes and interactions of Earth's systems and the structure and dynamics of Earth and other objects in space. (Focus: Geology, Meteorology, Astronomy, Oceanography)

4.1. Fossils are evidence of past life 9
Suggested Titles for Colorado Science State Standard 4.1.

4.2. Natural processes change Earth's surface (for example: weathering, erosion, mountain building, volcanic activity, earthquakes and floods) 42
Suggested Titles for Colorado Science State Standard 4.2.

4.3. Many of the Earth's resources can be conserved, recycled and depleted 17
Suggested Titles for Colorado Science State Standard 4.3.

4.4. Weather is different from climate 85
Suggested Titles for Colorado Science State Standard 4.4.

4.5. Most of the Earth's surface is covered by water, that most of the water is salt water in the oceans, and that fresh water is found in rivers, lakes, underground sources and glaciers 22
Suggested Titles for Colorado Science State Standard 4.5.

4.6. Water exists on Earth in different states (solid, liquid, gas) and changes from one state to another (for example: evaporation, condensation and precipitation) 11
Suggested Titles for Colorado Science State Standard 4.6.

4.7. There are basic components of the solar system (for example: Sun, planets, moons) 32
Suggested Titles for Colorado Science State Standard 4.7.

4.8. The Earth and Sun provide a diversity of resources (for example: soils, fuels, minerals, medicines and food) 32
Suggested Titles for Colorado Science State Standard 4.8.

4.9. The rotation of the Earth on its axis, in relation to the Sun, produces the day-and-night cycle and the orbit of the Earth around the Sun completes one year 2
Suggested Titles for Colorado Science State Standard 4.9.

CO.5. Students understand that the nature of science involves a particular way of building knowledge and making meaning of the natural world.

5.1. When a science experiment is repeated with the same conditions, the experiment generally works the same way 32
Suggested Titles for Colorado Science State Standard 5.1.

5.2. Models are used to represent events and objects (for example: comparing a map of the school to the actual school; a model of the Earth to the Earth itself) 32
