A. mix them all up in a waste container and dump them in the trash B. pour them all down the sink while running the water to dilute C. Follow the instructions given to properly dispose of the particular chemicals D. Mix the chemicals in a flask and heat the mixture until it evaporates into the air

Glance at the cylinder and write down the first number you see D. read the level of liquid at the middle of the meniscus at eye level

15. Objective 1.01-Scientific Method 1. Make an observation 2. Identify the problem/question 3. Form a hypothesis 4. Design an experiment 5. Perform an experiment 6. Analyze Data 7. Make conclusions

16. Objective 1.01 Scientific Method 1. Observation: Observe birds in flight 2. Question: How do birds fly? 3. Hypothesis: The wing designs of birds catch air differently 4. Experiment: Make and fly different designs of paper airplanes to test the hypothesis 5. Analyze Data: take notes on flight patterns of paper airplanes. Create a data table on how each airplane flies. 6. Conclusion: The size and shape of the wing gives lift to the bird

17. Scientific Method Vocabulary 1. Independent variable-variable that is changed 2. Dependent variable-variable that is measured or counted-changes in response to the independent variable 3. Control-things the investigator keeps in control in order to keep them the same for all samples 4. hypothesis-statement that gives the best possible response to the question and should be based on already known facts (educated guess)

18. Scientific Method Quantitative Data: numbers Ex: 500, 6, ten Qualitative Data: no number Ex: brown, big, tall Prediction- forecast (educated guess) of the possible results of events
