The three organizing concepts of this class are structure and function, matter and energy and cause and effect. In this class students will be asked to...
-develop and use models
-plan and implement investigations
-evaluate competing solutions
-engage in discussions
Living Organisms: What does it mean to be alive....biologically speaking...
(7.L.1 Understand the processes, structures and functions of living organisms that enable them to survive, reproduce and carry out the basic functions of life.)
- Describe the structures and functions of single-celled organisms as the basis of the structures and functions of all living organisms.
- Investigate euglena, amoeba, paramecium, volvox
- Compare plant to animal
- Create a map of the body systems and their cell and tissue types; cells - tissues -- organs -- systems..
- Summarize the general functions of the major systems of the human body and how they interact with each other.
- digestion, respiration, reproduction, circulation, excretion
Evolution and Genetics: How do you inherit your traits and how do traits in populations change over time?
(7.L.2 Understand the relationship of the mechanisms of cellular reproduction, patterns of inheritance and external factors to potential variation among offspring.)
- Describe asexaul reproduction and it’s genetic variability
- Describe sexual reproduction and it’s potential for genetic variability.
- Use punnett squares to predict genetic variability.
- Describe the impacts of the environment and lifestyle on biological inheritance.
- Describe common genetic diseases.
Climate and Atmosphere: How are life and the atmosphere intricately linked?
(7.E.1 Understand how the cycling of matter (water and gases) in and out of the atmosphere relates to Earth’s atmosphere, weather and climate and the effects of the atmosphere on humans.)
- What gases make up the atmosphere?
- Explain how the water cycle impacts weather patterns.
- Relate high and low pressure systems, movement of air masses, frontal boundaries and weather conditions.
- Predict weather based on data. Analyze weather maps, satellites and radar.
- Model how global winds, especially the jet stream, impact weather and climate.
- Connect human health to climate and air quality, explain how the atmosphere is monitored, and how we practice stewardship.
Forces and Motion: What causes motion and how do humans increase the efficiency of machines that do our work?
(7.P.1 Understand motion, the effects of forces on motion and the graphical representations of motion.
7.P.2 Understand forms of energy, energy transfer and transformation and conservation in mechanical systems.)
- Describe the motion of an object’s direction and speed (constant and varying) compared to other objects and by creating and interpreting graphs.
- Describe how forces act on an object; friction, gravity, magnetism, balanced and unbalanced.
- Explain the relationship between kinetic, potential and mechanical energy and how energy is transformed through each.
- Recognize that transferred energy is work.
- Explain that electrical currents require a closed loop.
- Explain how each kind of simple machine creates mechanical advantage and increases efficiency.
What about the Scientific Method? This ‘unit' is embedded throughout your 7th grade science course. You will explore, discuss and apply the scientific method in many varied ways. We will conclude the year with an exploration of the role science plays in our society and demonstrate an increasing ability to recognize what science ‘is' and ‘is not'.
- Structure questions that can be answered through scientific investigations, control and manipulate variables, define operationally, communicate procedures, results, and explanations, formulate further questions.
- Scientific text, articles, popular press
- Measurement in today's world.
In 7th grade science you will learn about...
- Human anatomy and physiology: What are the parts of the human body and how do they interact to form the systems that create complex life-forms?
- Genetics and Inheritance: How do you inherit and pass on your physical traits?
- Atmosphere and Climate: What is our atmosphere made up of? What are the physical properties of our atmosphere? How does our atmosphere impact life and how does life impact our atmosphere?
- Physics: What are the forces the cause motion? How do humans design machines that take advantage of these forces to do work?
