1. Trying Out The Scientific Method SNC2D

2. Trying out the Scientific Method ●Some of you will be studying paper airplanes. ●What question do we want to answer about paper airplanes? ● How does the weight of paper affect how far a paper airplane will fly? ○Make a hypothesis for this question – make sure it is testable. ○Write it as an "if...then" statement. ○State your variables – independent variable, dependent variable and 3+ control variables ●Now, design a controlled experiment to test the hypothesis. This will be your procedure. ○Materials needed ○Numbered steps to test your airplane hypothesis ●Create a data table to record your results. ○Remember your rules for making a good data table. ●Run your experiment ○ Make detailed observations. Both qualitative and quantitative. ● Analysis o Graph your data using a type of graph you feel best represents your data o Explain your results and how they relate to your question. Be detailed. o State two errors (a factor that would have affected your dependent variable and therefore effected your analysis) and one improvement.

3. Blast Off! ●Some of you will be studying rockets…. ●What question do we want to answer about the lab? ● How much Alka-Seltzer is needed to blast off the lid of a canister in 8 seconds? ○Make a hypothesis for this question – make sure it is testable. ○Write it as an "if...then" statement. ○State your variables – independent variable, dependent variable and 3+ control variables ●Now, design a controlled experiment to test the hypothesis. This will be your procedure. ○Materials needed ○Numbered steps to test your hypothesis ●Create a data table to record your results. ○Remember your rules for making a good data table. ●Run your experiment ○ Make detailed observations. Both qualitative and quantitative. ● Analysis o Graph your data using a type of graph you feel best represents your data o Explain your results and how they relate to your question. Be detailed. o State two errors (a factor that would have affected your dependent variable and therefore effected your analysis) and one improvement.

4. What to Submit – The Lab Report ● Meaningful Title with date, name & lab partner ● Question, Hypothesis (with reasoning!) ● Variables (IV, DV, CV(3)) ● Safety – 2 precautions with explanations for what to do if it does happen. ● Materials and Methods (in past tense since it is what you have done) ● Observations Table (quantitative & qualitative) ● Analysis (graph, explanation of results, errors (2) and improvements(1)
