Question

in an experiment, students compared antibacterial hand sanitizer to regular hand soap. they washed their hands with either sanitizer or soap and warm water for two minutes, then dried them with a paper towel. the control group used only warm water (no soap or sanitizer), while the experimental group used soap and hand sanitizer. after washing their hands, the students swabbed their hands and applied the swabbed samples to culture plates and incubated them. they later counted and recorded the bacterial growth as shown in the data table. 8. based on the data, the students concluded that the hand sanitizer was the most effective at killing bacteria. how would you respond to the students conclusion? steve uses balloons to investigate the expansion and contraction of gases at different temperatures. he knows that particles move faster at higher temperatures. he develops the hypothesis that faster particle motion makes gases expand. he fills three balloons with the same amount of gas, places them at different temperatures and measures the circumference of each balloon. 9. which type of scientific investigation did steve choose for his experiment? 10. what tool will be useful to collect the information that he needs? 11. what is the independent variable from this experiment? 12. what is the dependent variable from this experiment? 13. what are at least 2 controlled variables from this experiment? jenny bravo loves orville redenbacher popcorn, but she wants to know which brand of popcorn pops the most popcorn. she conducted an experiment by popping orville redenbacher popcorn, jiffy pop popcorn, and movie time popcorn for the same amount of time in the same microwave. she then counted all the un - popped kernels and determined which brand pops the most popcorn by the fewest number of un - popped kernels. identify the variables of this experiment. 14. what is the independent variable? 15. what is the dependent variable?
