(COPY THIS IN YOUR JOURNALS)
CONVECTION CURRENT = IS THE CIRCULAR
MOTION IN A LIQUID or air CAUSED BY
HEATING AND COOLING.
Question and Hypothesis
QuestionWhen confetti paper is added to boiling water,
what direction will the confetti paper travel?
HypothesisIf………., then…. because….
CONVECTION CURRENT LAB PROCEDURES
• Fill beaker with 300 mL of water
• Put on Safety Glasses
• TURN ON HOT PLATE (HOT PLATE SHOULD NOT BE HIGHER
THAN 4)
• ALLOW BEAKER OF WATER TO HEAT FOR 3 MINUTES.
• SPRINKLE CONFETTI PAPER INTO THE BEAKER OF WATER.
• PUT TWO DROPS OF DYE INTO THE BEAKER OF WATER.
• OBSERVE THE MOVEMENT OF THE CONFETTI PAPER.
• DRAW THE BEAKER OF WATER AND USE ARROWS TO SHOW
THE MOVEMENT OF PAPER.

• Claim
–A response to a question
Draw a conclusion CER
• Evidence
– Relevant data or facts that support your claim
– Observations that support the claim
Draw a conclusion CER
• Reasoning
– Explains how convection currents work in the
earth’s mantle?
– Justifies why the data, facts, or observations
support the claim
– Includes appropriate content concepts or
principles
CONCLUSION QUESTIONS
LEAVE SPACE BETWEEN EACH QUESTION
1. Explain the process by which the water is
heated.
2. Describe the motion of the water as made
visible by the dye.
3. Why does convection occur?
4. When will the convection cease? Why?
5. How do Convection Currents happen in the
mantle of the earth?
6. Explain how this process makes the tectonic
plates move?
