Procedure To Make Metric Measurements Of Volume Using A Meterstick
Introduction In a scientific observation, measurements are necessary to collect data and to give the objects that we observe a quantitative identity. In order to make valid measurements, scientists strive to make their measurements both accurate and precise. Today, scientists use the metric system, which is the most widely used system of measurement. The purpose of today’s lab is to make metric measurements of length, mass, volume, and temperature.
Summary of the Procedure
Procedure 2.1 The purpose of this procedure is to make metric measurements of length and area of various different objects using a meterstick.
Step 1: Examine the intervals on the meterstick.
Step 2: Make the measurements of various objects including yourself, …show more content…
Step 1: Obtain a graduated cylinder. Determine what the markings represent. Step 2: Measure the amount of mL it takes to fill a cup. Step 3: Measure the amount of liters there are in a gallon.
Procedure 2.3 The purpose of this procedure is to measure the volume of an object by using water displacement. Step 1: Obtain a 100-mL graduated cylinder, thumb-sized rock, and a glass marble.
Step 2: Fill the graduated cylinder with 70 mL of water. Step 3: Submerge the rock into the graduated cylinder. Notice the water level rising. Step 4: Observe the meniscus of the fluid and record the volume. Step 5: Calculate and record the volume of the rock by subtracting the original volume from the new volume Step 6: Repeat steps 2-5 to find the volume of the marble. Measure and record.
Procedure 2.4 The purpose of this lab is to learn how to use a pipet. Step 1: Add 100 mL of water to a 100mL beaker.
Step 2: Use a 5 mL pipet to remove some water from the beaker
Step 3: Fill the pipet to the zero mark
Step 4: Line up your eye with the bottom of the meniscus to read the liquid level
Step 5: Release the water into the …show more content…
Then, measure the mass of the object by placing it on the weighing pan and adding weights until the beams balance. Record the mass by finding the sum of the weights added to the beams. Step 2: If using an electronic balance, turn on the balance and let it warm up for 5 minutes. Press the “tare” button to reset the display to 0.0 g. Place the object on the measuring pan. After the display stabilizes, read and record the object’s mass. Step 3: If weighing a liquid, powder, or similar specimen, place an empty beaker or piece of weighing paper (on which to place the liquid or powder) on the measuring pan. After the display stabilizes, press “tare” to reset the display to 0.0 g. Place liquid into beaker (or powder onto paper). After the display stabilizes, record the mass.
Procedure 2.6 The purpose of this procedure is to make metric measurements of temperature using a thermometer. Step 1: Obtain a thermometer. Handle it with care. Inform an instructor if it breaks. Step 2: Examine markings to determine the range of temperatures that can be measured. Step 3: Measure the room temperature, cold tap water, hot tap water, and inside a
