Have you ever tried to walk on the beach when the sand
was so HOT it burned your feet?
Table one contains data collected by heating dry sand on the beach. Table
two contains data collected by heating wet sand on the beach. The sand is
heated at the same temperature over the same period of time.


Graph the data from table one-dry sand- on a coordinate plane (use a
colored pencil).
Choose a scale and interval for the graph.
Label the x-axis and the y-axis.
Now graph the data from table two-wet sand- on the same coordinate
plane (use a different colored pencil).
After you have properly graphed the data, let a partner look at your
graph. Then, Answer the following questions about your graph:
1. Which variable did you put on the x-axis? ___________________ Which
variable did you put on the y-axis? _____________
2. Which variable is the independent variable? ___________________
Which variable is the dependent variable? ____________________
Explain why you think this. ____________________________________
_________________________________________________________
3. Would it make sense to connect the points on this graph? Why or why
not? _____________________________________________________
4. Explain how the temperature of sand changed over time. _____________
5. Compare and contrast how the graphs are similar and different.
Dry Sand
Both
Wet Sand
___________
6. Explain why dry sand heats faster than wet sand. __________________
7. If I were going to go walk on the beach, and I did not want to burn my
feet, explain to me where I should walk.
