  1. Science, Agriculture, and You! Plants, Pizza, Animals, and You

  2. In your lab books • Table of Contents: Defining Science • Objective: Determine what makes information credible • Journal Topic: What is “good” science?

  3. DiHydrogen Monoxide • Is the major component of acid rain • May cause severe burns • Prolonged exposure in solid form can cause tissue damage • Death occur every year due to inhalation, even in small quantities • Has been found in excised tumors of terminal cancer patients • Often used in nuclear power plants • Major component in pesticides

  4. Take action and sign the petition to ban it! Why is the substance still legal?

  5. What is danger chemical made up of? The answer may shock you!

  6. H2O

  7. Wait, what? • Knowing and understanding what makes information credible is extremely important. • As consumers, we are constantly bombarded with new information, and not all of it is good • You can’t anything on the internet that isn’t true, right?  • In Agriculture and science we are presented with new research all the time. It is so important to be able to evaluate claims to determine their validity.

  8. A Good Scientific Attitude. . . • Curiosity: Asking questions leads to new discovers. • Skepticism: Question existing ideas and refuse to accept answers without evidence or data • Open-Mindedness: Accept different ideas that does not agree with your • Creativity: Thinking outside of the box may be the only way to design successful experiments

  9. What are the components of science? • Hypothesis: a statement based on observations to be tested. It should be written as an “If . . . Then” statement • If I chew bubble gum for 5 minutes and weigh it every minute, then the mass of the gum will increase. • Controlled Experiment: only one of the variables is changed • Independent Variable: The variable that is changed on purpose • The mass of the gum • Dependent Variable: the variable observed and but is not manipulated by you • The time the gum was chewed

  10. What are the components of science? • Data: the information gathered from the experiment • Quantitative Data: information that can be measured • The mass of the gum • Qualitative Data: description of outcome • What it looked like, what the texture was, etc. • Conclusion: What does the data prove? Was your hypothesis correct? Can someone else get the same results?

  11. So. . . . • How could we use science find out if Double Stuf Oreos are really double stuffed?
