CER Skills
What does CER stand for?
Claim, Evidence, Reasoning!
MANY questions require this for Wednesday's test.
On the graph where is the title usually found?
At the top of the graph.
What tool measures temperature?
A Thermometer.
What carries energy from place to place?
Waves.
Which is the variable that changes on purpose?
Independent or Dependent Variable?
Independent.
A student says, “Plants grew taller in sunlight.” Which part of CER is this?
The Claim.
What is usually found on the y-axis or side of the graph?
Numbers / Data of the experiment or change.
Think CAUSE and EFFECT!
What type of front usually brings thunderstorms?
A Cold Front!!
(Blue!)
What part of the waves is the highest point?
The Crest.
What is measured in an experiment?
Independent or Dependent Variable?
Dependent variable.
Data shows Plant A grew 8 cm and Plant B grew 3 cm. Which part of CER uses these numbers?
Evidence
A weather map shows closely packed isobars. What kind of winds are likely happening?
Strong winds.
High pressure systems usually bring what kind of weather?
Clear and Calm.
If a wave has more amplitude, what happens to its energy?
The energy increases!
*It's a match. More amps! More energy!
Why do Scientist use a control group?
To compare results accurately.
Why do scientists use evidence in explanations?
To support and prove their claim.
Why do Scientists use models?
To explain a point that is hard to see without a visual.
What is the difference between WEATHER and CLIMATE?
Weather is the short term; Climate is the long term patterns in an area.
Which wave travels fastest through solids?
A student tests plant growth with different amounts of water. What should stay the same?
LIST! 2 out of 3 at least.
The soil, the type of plant, the sunlight.
A student writes: “The metal spoon got hotter faster because metal transfers heat well.” Which CER part is shown MOST?
Reasoning.
A student looks at a food web model. The insect population suddenly decreases.
Which organism would MOST LIKELY decrease next?
The animal that EATS this animal.
Warm air rises and cool air sinks. What does this movement create?
Wind (Convection Currents!)
Two waves have the same height, but one wave has many more crests close together.
Which wave has the greater frequency?
The wave with more closely packed crests.
Why is it necessary to repeat an experiment?
In order to have more reliable results.
