Expected Performances

Science and Technology in Society – How do science and technology affect the quality of our lives?

3.4 - Earth materials provide resources for all living things, but these resources are limited and should be conserved.

¨       Decisions made by individuals can impact the global supply of many resources.

 

B 7.        Describe how earth materials can be conserved by reducing the quantities used, and by reusing and recycling materials rather than discarding them.

Content Standards

Expected Performances

Forces and Motion – What makes objects move the way they do?

4.1 - The position and motion of objects can be changed by pushing or pulling.

¨       The size of the change in an object’s motion is related to the strength of the push or pull.

¨       The more massive an object is, the less effect a given force will have on its motion.

 

B 8.        Describe the effects of the strengths of pushes and pulls on the motion of objects.

B 9.        Describe the effect of the mass of an object on its motion.

Matter and Energy in Ecosystems (Back to Top)

Content Standards

Expected Performances

Matter and Energy in Ecosystems – How do matter and energy flow through ecosystems?

4.2 - All organisms depend on the living and non-living features of the environment for survival.

¨       When the environment changes, some organisms survive and reproduce, and others die or move to new locations.

 

B 10.        Describe how animals, directly or indirectly, depend on plants to provide the food and energy they need in order to grow and survive.

B 11.        Describe how natural phenomena and some human activities may cause changes to habitats and their inhabitants.  

 Practice websites:
  Food Chain - BrainPop movie on the food chain

4.3 - Water has a major role in shaping the Earth’s surface.

¨       Water circulates through the Earth’s crust, oceans and atmosphere.

B 12.        Describe how the sun’s energy impacts the water cycle.

B 13.        Describe the role of water in erosion and river formation.

Expected Performances

Energy Transfer and Transformations – What is the role of energy in our world?

4.4 - Electrical and magnetic energy can be transferred and transformed.

¨       Electricity in circuits can be transformed into light, heat, sound and magnetic effects.

¨       Magnets can make objects move without direct contact between the object and the magnet.

B 14.        Describe how batteries and wires can transfer energy to light a light bulb.

B 15.        Explain how simple electrical circuits can be used to determine which materials conduct electricity.

Expected Performances

Energy Transfer and Transformations – What is the role of energy in our world?

5.1 - Sound and light are forms of energy.

¨       Sound is a form of energy that is produced by the vibration of objects and is transmitted by the vibration of air and objects.

¨       Light is a form of energy that travels in a straight line and can be reflected by a mirror, refracted by a lens, or absorbed by objects.
