1. Recipe for Oatmeal Treats

2. Some butter Some sugar A little salt A lot of flour A bunch of nuts A whole lot of oatmeal A little baking powder Combine together these ingredients:

3. Next… • Mix well • Heat up the oven • Bake them for a long time.

4. What is wrong with this recipe?

5. Think about this: • When have you ever needed to know an exact quantity or size? • Describe a time when you had to explain to someone an exact quantity or dimension. • What equipment have you used to measure things?

6. Triple Beam Balance • Measures mass (how much stuff something is) • The readings are labeled with grams, such as 15.0g.

7. Rulers and Meter Sticks • Measure length (how long something is) • Label measurements with centimeters ( 5.3 cm) • 10 mm=1cm • 100cm = 1 m

8. Graduated Cylinder • Measures volume (how much space something takes up) • Measured in mL or cm3 (such as 9.3 mL)

9. Thermometer • Measures temperature (how much heat is in something) • Uses units called degrees Celsius or degrees Fahrenheit. Such as 37°C or 98.6°F

10. Spring Scale • Used to measure the strength of a force (a push or a pull) • The unit we use to label with is the Newton (such as 5 N of force)

11. Scientists use a variety of tools for measuring • Triple beam balances for mass • Thermometers for temperature • Spring Scales for force • Graduated Cylinders for volume • Rulers and meter sticks for length

12. Using a triple beam balance • Rachel Spencer shows us how!

13. Using a triple beam balance • 1. Move all riders to zero • 2. Use the adjusting screw to set the pointer at zero on the indicator. • 3. Place an object on the pan

14. 4. Adjust the riders (starting with the biggest) until the pointer points at zero on the indicator. • 5. Add the grams on the 3 beams together • 6. Write the total mass on your paper • 7. Label your answer in grams.

15. Temperature

16. Temperature • Tells us how much heat is in something • Measured with a thermometer • Thermometers show degrees Celsius or degrees Fahrenheit. (Lab thermometers show °C)

17. Using a thermometer • Let Steve and Myleishka show you how! • Bulb of thermometer should be in center of the liquid • Keep it in the liquid • Don’t shake down the thermometer or use it as a stirring rod

18. Important Temperatures • Boiling Point of Water • Normal body temperature • Freezing Point of Water • Room Temperature

19. Measuring volume of a liquid • Fallon Johnson uses a graduated cylinder to measure the volume of a liquid. • Put the graduate on a level surface • Read the volume from eye level • Use the bottom of the meniscus.
