Why use Scientific Tools?
• Scientific tools (ex. graduated cylinder,
thermometer, ruler, balance) allow you to
collect accurate data during scientific
• Throughout the week, we will be
investigating the proper ways to use these
tools during science lab.
How many of you have
ever baked a cake or
made a batch of
cookies? Well- chances are, you’ve used tools
to MEASURE precise ingredients in
order to make that tasty treat perfect!
By measuring something like flour,
you are measuring VOLUME!!!
What is Volume?
• Volume is the amount of space an
object takes up, whether liquid (ex. Water)
or solid (ex. Sugar)
Suppose you were doing an experiment with
plants and you wanted to find out how
much water tomato plants need.
Plant A will receive a little bit of water,
Plant B more water, and
Plant C the most water.
How should you measure the water?
• The best way to answer that question is by
using graduated cylinders, measuring
cups, beakers, & droppers to accurately
measure the volume of the water needed.
• Most of these tools are measured in liters
(L) or milliliters (mL).
NOTICE: These tools all have a curved tip-this
makes it easier to pour liquids and solids
• Measuring cups and measuring spoons
are used to measure liquids (water, oils,
etc) and solids (sugar, salt, etc).
• They come in different sizes- you’ve
probably seen them if you’ve ever made
brownies or a cake- the ½ cup, the ¼ cup,
and so on.
Beakers and Graduated Cylinders
• These are used to measure liquids
• They range in a variety of sizes depending
on how much volume you need to find.
The Dropper (Pipet)
• This tool is used to move very
small amounts of liquid or to
measure volume by counting
• Hold the dropper upright and
put the tip of the dropper in
the liquid. Gently squeeze the
bulb on the dropper to allow
the water to fill the dropper.
Release the bulb slowly one
drop at a time.
**NEVER put this tool in your mouth**
Steps to measure volume:
– Make sure your eyes are
level with the container you
– Read the measurement on
– Record your data
– You measure solids the
same way you do liquids.
Make sure the top is
smooth before you read
A) 80 mL
B) 75 mL
C) 70 mL
D) 76 mL
• Define the word “Volume”
• Identify at least three tools used to
• Which of these is used to measure the
volume of a liquid?
Cameron drinks 2 liters of water every day. He
said his doctor told him it was good for him. If he
continues to drink 2 liters of water each day, how
many liters will he drink in one week?
There are 7 days in a week.
If Cameron drinks 2 liters a day, all we need to do is multiply
7 x 2 = 14
Cameron will drink 14 liters of water in one week!
