use strategies to make ways to find ways to find the circumfrence or circles

example problem

pi: π=c/d = 3.14 or π or 22/7=π . how to find the circumfrence of the circle from diameter: d of circle *π=c

lesson

    to find the circumfrence of a circle you multiply the diameter by pi or π. to find the diameter you divide the circumfrence by π

Question:

WILL WATER HEAT UP FASTER IN HOT OR COLD WATER? WILL A TRANSLUCENT CAP MAKE A DIFFERENCE?

Hypothesis:

IF BLACK COVERED HEATS IT UP FASTER THEN WHITE COVERED HEATS IT UP SLOWER. THE SAME FOR THE UNCOVERED.

Procedure:

I MAKE A WHITE UNCOVERED SOLAR WATER HEATER AND PUT A THERMOMETER IN IT. THEN I RECORD THE TEMP. EVERY 5 MINUTES. THEN I FIND THE PATTERN.

Materials:

A PLASTIC CONTAINER, TAPE, BLACK OR WHITE PLASTIC, THERMOMETER, AND/OR CAP W/ SLIT, TEST RECORDING SHEET, AND A SUNNY DAY
