  1. How to Write Scientific Statements

  2. Example We Will Use • Changing the amount of sunlight changes how tall plants will grow

  3. Independent Variable - IV • The variable that “I” (the scientist) changes • Be specific • Don’t just write “sunlight” • Should be “amount of sunlight” • Include units in ( ) • How are you going to measure it? Written correctly: Amount of Sunlight (hours)

  4. Dependent Variable - DV • The variable that “depends” on the other variables • What will be measured? • Be specific • Don’t just write “how tall a plant grows” • What are you measuring? Height • Height of what? • Should be “height of plant” • Include units in ( ) • How are you going to measure it? Written correctly: Height of Plant (cm)

  5. Hypothesis • Use the IV and DV you just identified • Hypothesis is… • IF THE IV IS CHANGED, THEN THE DV WILL CHANGE. • Make sure you are specific about HOW the variables will change. What do you think will happen? Written correctly: If the amount of sunlight is increased, then the height of the plant will decrease.

  6. Title • Always capitalized like the title of a book • The Effect of IV on DV Written Correctly: The Effect of the Amount of Sunlight on the Height of Plants
