Science Stuff The Alabama Science Third Grade Course of Study with some links that help explain the concepts. (links added by ME!) Physical Science

Students will:

1. Classify substances as soluble or insoluble. Examples: soluble—sugar in water, powdered drink in water;

insoluble—sand in water, oil in water

2. Identify physical and chemical changes of matter. Examples: physical—chopping wood,

chemical—burning wood 3. Describe ways energy from the sun is used. Examples: plant growth, light, heat
 * Identifying fossil fuels as a source of energy

4. Define force and motion. Examples: lifting, pushing, pulling Examples: rubbing hands together, applying sandpaper to wood
 * Identifying forces that change an object’s position or motion
 * Identifying sources of friction
 * Describing the force of gravity

5. Identify the relationship of simple machines to compound machines. Example: pencil sharpener composed of a wheel and axle, inclined plane, and wedge

Life Science

6. Identify structures and functions of the muscular and skeletal systems of the human body. 7. Describe the life cycle of plants, including seed, seed germination, growth, and reproduction. Examples: evergreen or deciduous, flowering or nonflowering Examples: helpful—provide food, control erosion;
 * Describing the role of plants in a food chain
 * Identifying plant and animal cells
 * Describing how plants occupy space and use light, nutrients, water, and air
 * Classifying plants according to their features
 * Identifying helpful and harmful effects of plants

harmful—cause allergic reactions, produce poisons 8. Identify how organisms are classified in the Animalia and Plantae kingdoms. 9. Describe how fossils provide evidence of prehistoric plant life. Example: plant fossils in coal or shale providing evidence of existence of prehistoric ferns 10. Determine habitat conditions that support plant growth and survival. Examples: deserts support cacti, wetlands support ferns and mosses Earth and Space Science
 * Identifying how bees pollinate flowers
 * Identifying photosynthesis as the method used by plants to produce food

11. Describe Earth’s layers, including inner and outer cores, mantle, and crust. ​Inner and outer core interactive site []

 * Classifying rocks and minerals by characteristics, including streak, color, hardness, magnetism, luster, and texture

12. Identify conditions that result in specific weather phenomena, including thunderstorms, tornadoes, and hurricanes. Examples: positive—flooding deposits good soil when waters recede,
 * Identifying cloud types associated with specific weather patterns[|The Cloud Song]
 * Identifying positive and negative effects of weather phenomena

negative—flooding kills crops 13. Describe ways to sustain natural resources, including recycling, reusing, conserving, and protecting the environment.
 * Identifying technology used to record and predict weather, including thermometers, barometers, rain gauges, anemometers, and satellites
 * Explaining symbols shown on a weather map
 * [|Weather Whiz Kids]
 * Organizing weather data into tables or charts
 * Recognizing the impact of society on human health and environmental conditions

14. Describe the position of Earth, the moon, and the sun during the course of a day or month.
 * Describing various forms of technology used in observing Earth and its moon
