Examples: rubbing hands together, applying sandpaper to wood

• 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 ||
 * 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.

• 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

Examples: evergreen or deciduous, flowering or nonflowering

• Identifying helpful and harmful effects of plants

Examples:

- helpful-provide food, control erosion;

- harmful-cause allergic reactions, produce poisons

• Identifying how bees pollinate flowers

• Identifying photosynthesis as the method used by plants to produce food ||
 * 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 ||
 * 11.) Describe Earth's layers, including inner and outer cores, mantle, and crust.

• 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.

• Identifying cloud types associated with specific weather patterns

• Identifying positive and negative effects of weather phenomena

Examples:

- positive-flooding deposits good soil when waters recede,

- negative-flooding kills crops

• Identifying technology used to record and predict weather, including thermometers, barometers, rain gauges, anemometers, and satellites
