What form do we write Scientific Questions? | Does the (IV) effect the (DV)? |

If the mass of a seed increases, then the height of the plant produced will increase. What is the DV? | Height of the plant |

If the mass of a seed increases, then the height of the plant produced will increase. What is the scientific question? | Does the mass of the seed effect the height of the plant? |

What form do we write a Hypothesis? | If...then... |

What must an investigator do before he/she can form a hypothesis? | Define the problem |

What error is made...If the height and mass of the building increases, then the length of the shadow will increase. | there are too many Independent Variables (height and mass) |

This is the step where you explain whether data supports the hypothesis and give future applications? | Draw Conclusion |

What are Sources of Error (SOE's)? | anything that could affect the results |
