Scientific tools measuring volume

  1. 1. Essential Questions Prior Knowledge • What is Volume? • What tools do I use to measure volume? • How do I find the volume of different liquids & solids?
  2. 2. Why use Scientific Tools? • Scientific tools (ex. graduated cylinder, thermometer, ruler, balance) allow you to collect accurate data during scientific investigations. • Throughout the week, we will be investigating the proper ways to use these tools during science lab.
  3. 3. 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!!!
  4. 4. What is Volume? • Volume is the amount of space an object takes up, whether liquid (ex. Water) or solid (ex. Sugar)
  5. 5. Volume 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?
  6. 6. • 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
  7. 7. Measuring Cups • 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.
  8. 8. 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.
  9. 9. The Dropper (Pipet) • This tool is used to move very small amounts of liquid or to measure volume by counting drops. • 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**
  10. 10. Measuring Volume Steps to measure volume: – Make sure your eyes are level with the container you are measuring – Read the measurement on the scale. – Record your data – You measure solids the same way you do liquids. Make sure the top is smooth before you read the volume. 80 mL
  11. 11. You Try… A) 80 mL B) 75 mL C) 70 mL D) 76 mL Answer: D
  12. 12. • Define the word “Volume” • Identify at least three tools used to measure volume.
  13. 13. • Which of these is used to measure the volume of a liquid?
  14. 14. 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? Example: 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!
