Absent DENSITY/CONVECTION CURRENT LAB

Instructions Students will view the slides as if they were actually doing the lab in class. Students will record their answers down in the geosphere packets pages There are two parts to this lab

Question and Purpose of the lab Purpose: to understand how convection currents inside Earth affect tectonic plates Question: How are density and convection currents related?

Definition: mass divided by volume or the amount of mass in a give volume

Find the mass of the empty beaker Recorded in data table found on page 10

Filled the beaker with 100 mL of water and then found the mass of the beaker plus water. Recorded in data table found on page 10

Find the mass of the second empty beaker Recorded in data table found on page 10

Filled the empty beaker with 100 mL of oil and then found the mass of the beaker plus oil. Recorded in data table found on page 10

Find the mass of the liquids along Subtract the mass of the liquid plus the beaker from the mass of the beaker alone. Recorded in data table found on page 10

Find the density of each liquid by dividing the mass of the liquid alone by its volume Hint the volume of each liquid is 100 mL Recorded in data table found on page 10

Write a hypothesis of what will happen when the oil is poured into the water on question 8 on page 10. Don’t forget to put the why!

The oil was gently poured into the water beaker. Answer question 10 on page 10.

Skip to question 14 on page 11 of your geosphere packet. Write your hypothesis and reason why for the wooden disk.

The wooden disk was put gently into the beaker. Answer question 16 on page 11

Write your hypothesis and reason why for the ice cube. The ice cubes were colored green so they were easier to see.

Placed the ice cube gently into the beaker. Answer question 13 Answer question 17

Instructions Please go to the following YouTube link to watch a convection current. After watching it answer the questions found on page 12 of your geosphere packet. The tank is on two buckets. One side is cold the other side is hot. Some of the questions ask about pepper, which was not demonstrated in the video. Please imagine that pepper was sprinkled on top. Hint with the pepper questions, which way is the water moving.
