AGENDACONVECTION LAB

BELLWORK (COPY THIS IN YOUR JOURNALS)

CONVECTION CURRENT = IS THE CIRCULAR MOTION IN A LIQUID or air CAUSED BY

HEATING AND COOLING.

Question and Hypothesis

Question-When confetti paper is added to boiling water, what direction will the confetti paper travel?

Hypothesis-If………., 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.

Draw a conclusion CER

• 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?
