Pouring into Test Tube

                 To pour a liquid into a test tube first
                     put the liquid in a beaker. These
                     have a formed lip on the rim to
                     create an easier way of passing
                     the water.
                 In some cases, you will need a
                     funnel to omit spilling of the
                     product.
                 Measurements are all done in
                     milliliters (mL)
                 If using of harmful chemicals, use
                     gloves, protective goggles, and
                     do not sniff the liquid.
                 On oppropriate wear, please refer
                     to Amanda C.’s poster.
Measuring Out Your Liquid
   There is a specific way to measure a Test Tube. If looking at it from the wrong
    angle, your measurement will be off.
   To get the right angle, place your eyes parallel with the line of the liquid in the tube
    and at the same level.
   There is a slight curve in the liquid set in this tube. This is normal. Measure from
    the bottom of that curve.
