5th graders will complete the Physical Science Benchmark Assessment this Thursday, 2/7/19, and Friday, 2/8/19. Concepts / suggestions to review using lab folder contents such as graded assignments, Physical Science labs, and related vocabulary include:
States of matter and uses of heat energy – changing from solid to liquid to gas by adding heat, or gas to liquid to solid by taking heat away (think ice – water – steam).
Conductors and insulators of heat and electric energy.
Study the Energy Chart and be able to compare / contrast different types of energy and their characteristics.
Understand that Electrical energy must have a closed, complete circuit made out of a conductor to travel from the electrical energy source to a light bulb, buzzer, or other electrical device.
Know that light energy travels in a straight line through the air, but can change as it passes through certain matter.
When light bounces off (mirror, light colored object) and changes direction, that’s REFLECTION.
When light passes through (glasses, clear water, telescope lens) and changes action (bends), that’s REFRACTION.
Characteristics of matter including relative density compared to water, magnetism, ability to conduct or insulate energy, mass, physical state.
Characteristics of simple mixtures (dinner salad, iron shavings+sand+wood chips+gravel), and special mixtures called Solutions ( Sugar+water, Kool aid+water).
Forces: Gravity, friction, magnetism, push-pull, and their effect on matter / objects.
Know lab equipment and procedures, and be able to identify well – defined lab questions that we could research and answer in 5th grade. Evaluate lab set – ups and what questions they may be designed to answer.
Students should study / review about 20 minutes each night over these concepts using their lab folders.
There may be 2 Life Science questions on the test as a reminder of concepts taught earlier in the year. They would cover food webs / producers / consumers, and physical characteristics of living organisms.
We will begin EARTH SCIENCE next week.
