7th Science

Matter and Energy

• Recognize that energy from the Sun is made into chemical energy through photosyntesis
• Diagram the flow of energy through living systems. Ex: food chains, food webs, and energy pyramids
• Explain the cycling of matter in living systems, carbon cycle etc.

Physical and Chemical Changes

• Identify that all organic compounds are made of Carbon
• Know the difference between chemical and physical changes in the digestive system
• Recognize that large molecules such as carbohydrates are broken down into smaller molecules like sugars.

Force, Motion, and Energy

• Study situation where work is being done with different amounts of force
• Study the transformation of energy. Ex: chemical to heat
• Demonstrate how forces affect motion in everyday life. Ex: emergence of seedlings, geotropism, turgor pressure

Natural and Human impact on Earth

• Describe how catastrophic events impact ecosystems; floods, hurricanes, tornadoes
• Study the effects of weathering and erosion in ecoregions of Texas
• Model the effects of human activity on groundwater and surface water

Solar System

• Analyze characteristics of our Solar system that allows life to exist
• Identify how manned space exploration was made possible

Organisms and Enviroment

• Observe how different environments support a variety of organisms
• Describe how biodiversity supports an ecosystem
• Study the role of ecological succesion

Inherited Traits

• Study how organisms traits are inherited and vary through many generations
• Examine dichotomous keys to identify organisms structures
• Identify changes in genetic traits through the process of natural selection and selective breeding

Cells to Organisms

• Investigate the adaptations of organisms: why do fish have gills etc.
• Differentiate the structure of a plant and animal cell

Internal and External Stimulus

• Know how an organisms maintains balance in response to internal and external stimuli
• Investigate phototropism, and fight or flight
• Homeostasis

Characteristics of Organisms

• Know how reproduction passes traits through genetic material
• Compare the diversity of offspring from sexual or asexual reproduction
• Define heredity as the passage of genetic material through generations
