BioLab 1 - Using Measuring Tools

1. To find your own radial pulse, rest your right arm in the palm of your left hand. Curl the fingers of your left hand up around the thumb side of your right wrist. Place several fingers of your left hand along and just to the outside (thumb side) of the tendon that runs along your wrist. With gentle pressure, you should be able to feel your pulse.

Your resting pulse rate is ________________ pulses per 10 seconds.

That would be _______________ pulses per minute.

2. Measure the length of each of the five fingers on both of your hands.

The total length of the fingers on my right hand is ______________ centimeters.

The total length of the fingers on my left hand is ______________ centimeters.

The total length of the fingers of both hands is ______________ centimeters.

The total length of the fingers of both hands would be ___________ meters.

3. Determine the density of the solid object provided by your facilitator.

The mass of the object is ______________ grams.

The volume of the object is ______________ cm3.

The density of the object is ________________________ g/cm3.

What would be the density of the object in Kilograms per Liter? Show the calculation below:

 

 
Explain why this procedure would not work for an object whose density is less than water.

 

 


4. Measure the temperature of a sample of water. Add a dropper full of acid to the water and measure the temperature again.

The temperature of the water is ______________ oC.

The temperature of the water plus acid is ______________ oC.
