Irregular Volume WHAT TO DO: We use the idea of water displacement to find the volume of odd shaped objects. An object will displace, or move, an amount of water equal to its own volume. We use a graduated cylinder to measure volume in milliliters (ml). This is what a graduated cylinder looks like: WHAT TO DO: Write the name of the object on your answer sheet. Estimate the volume of the object in ml. Record this estimation on your answer sheet. Find the actual volume of the object by filling the graduated cylinder halfway with water. Record the amount, or volume, of water on your answer sheet. Carefully drop the object into the graduated cylinder. Record the new volume of the water on your answer sheet. Subtract the original volume of water from the new volume; this difference is the volume of the object. Record the actual volume of the object on your answer sheet. Repeat the steps for the second object. A meniscus is the curved wave line that the liquid makes inside the graduated cylinder. To tell how many milliliters of liquid are in the graduated cylinder, you must read the bottom of the meniscus wave.

Regular Volume WHAT TO DO: To find the volume of square or rectangular shaped objects, multiply the length by the width by the height (LxWxH). WHAT TO DO: 1. Write the name of the object on your answer sheet. Estimate the volume of the object in cc (cubic centimeters). Record this estimation on your answer sheet. Find the actual volume of the object using the formula LxWxH. Record the actual volume of the object on your answer sheet. Repeat the steps for the second object. Length = 4cm, Width = 6cm, Height = 5cm Volume = 4x6x5=120cm3 The volume of solids is measured in cm3 or cubic centimeters (cc). 1 cc = 1 ml

Temperature WHAT TO DO: There are 2 different containers at this station. Each one contains water at different temperatures. Look at the container labeled HOT. Estimate the temperature of the water in degrees Celsius. Record this estimation on your answer sheet. Use the thermometer to find the actual temperature of the water. Record the actual temperature of the water on your answer sheet. Repeat the steps for the container labeled COLD. SAFETY NOTES: Goggles must be worn around hot water. Thermometers are very fragile – be extremely careful with them. The metric system uses the Celsius scale to measure temperature. However, temperatures are still measured on the Fahrenheit scale in the U.S. Water freezes at 0° Celsius and boils at 100° Celsius.

Measuring Mass WHAT TO DO: With nothing on the platform, adjust the RIDERS so that each is at zero. Then check to make sure that the pointer swings to zero on the center mark. If the pointer is not even with the 0, call the teacher. After you place the object onto the platform, move the riders across the beam until the pointer is balanced. It is best to start with the hundreds, tens, and then ones. WHAT TO DO: Write the name of one object on your answer sheet. Estimate the mass of the object. Record this estimation on your answer sheet. Find the actual mass of the object. Record the actual mass on your answer sheet. Repeat the process for the second object. Circle the object with the greatest mass. beams riders pointer platform

Longer lengths are usually measured in meters. WHAT TO DO: Record the first object on your answer sheet. Estimate the length of the object in meters. Record this estimation on your answer sheet. Find the actual length of the object. Record the actual length of the object on your answer sheet. Find the length of the object in centimeters. Record on your answer sheet. Repeat the steps with the second object. The ruler above shows part of a meter stick. Each line is a millimeter. Every 10 millimeters is a centimeter. There are 100 centimeters in 1 meter.

Measuring Length WHAT TO DO: Record the first object on your answer sheet. Estimate the length of the object in centimeters. Record the estimation on your answer sheet. Find the actual length of the object. Record the actual length of the object on your answer sheet. Find the length of the object in millimeters. Record on your answer sheet. Repeat steps for the second object. The longer, numbered lines in this diagram show centimeter divisions. The smaller, unnumbered lines show millimeter divisions. The black line in this diagram is about 1.7 cm long. It is 17 mm long. When a measurement is not exact, estimate to the nearest mm.
