Which heats faster, land or water?

• Science experiment
• Arranged by
• Rebecca Peterson
• GMS 6th grade

2
Purpose To discover which heats faster, Land or
Water.

• Materials needed
• Beaker of sand and beaker of water
• Two thermometers
• Two tripods
• Two alcohol burners
• Two blocks of wood
• Two wire screens
• Ring stand and clamp

3
Set up the materials
4
Make a copy of this chart to mark down your
results.

• Minutes Temperature of sand Temperature of
  water
• 0 minutes
• 1 minute
• 2 minutes
• 3 minutes
• 4 minutes
• 5 minutes
• 6 minutes
• 7 minutes

5
Read the thermometers before you light the
burners.Write the temperatures down on the chart
at 0 minutes
6
Safety note IF the sand reaches a temperature of
about 68 degrees C or 150 degrees F before 7
minutes, put out both flames. Use the
temperature readings up to the point.

After double checking all equipment

• Light the burners.
• After one minute, read the thermometers. Write
  down the temperatures on the chart.
• Repeat this checking of the temperature every
  minute and write down the temperature on the
  chart each time for the next 6 minutes.
• Put out the flames.

Answer these questions on a separate piece of
paper.

• 1. What was the temperature of the sand before
  it was heated?
• 2. What was the temperature of the sand after it
  was heated for 7 minutes?
• 3. How many degrees hotter did the sand become?

• 4. What was the temperature of the water before
  it was heated?
• 5. What was the temperature of the water after
  it was heated for 7 minutes?
• 6. How many degrees hotter did the water become?

Conclusion

• This experiment shows that Sand heats up
• ( faster or slower ) than water.
• From this experiment we can see that land heats
  up ( faster or slower ) than water.
