How are Viktor s text messages affected by the recipe of love potion he consumes in his Butterbeer? b. How is the love potion affected by Viktor s heart-eye emojis? c. If Viktor consumes love potion with hair of Dumbledore, will he send more heart-eye emojis? d. What love potion causes Viktor to send more heart-eye emojis? 22. What is a good hypothesis for Hermione s experiment? a. I think Viktor will fall in love with Hermione because she gave him love potion with leaf of mandrake. b. If Viktor consumes love potion with scale of unicorn horn, then he will send Hermione more heart-eye emoji. c. If Viktor falls in love with Hermione because of the love potion, then the love potion was successful. d. If Viktor sends Hermione more heart-eye emojis, then she will put love potion made with leaf of mandrake in his Butterbeer.
4 23. Which needs to be kept constant in Hermione s experiment? a. Amount of love potion b. Cup Viktor drinks from c. Ingredients of love potion d. Viktor s grade in herbology class 24. What is the independent variable in this experiment? a. Amount of love potion b. How many flowers Hermione receives c. Love potion recipe d. Number of heart-eye emojis Use the following scenario to answer questions While playing Minecraft, Steve wonders which type of sword would be the best defense against an Enderman. He usually uses a wooden sword. He decides to create two other types of swords to test his theory he coats one in diamond plating and the other in iron. He keeps a tally of how many Endermen he is able to kill in a 10 minute time frame. 25. What is the dependent variable in this experiment? a. Location of Steve s house (in Minecraft) b. How much diamond Steve mines c. Number of Endermen killed d. Sword coating 26. What is the independent variable in this experiment? a. Location of Steve s house (in Minecraft) b. How much diamond Steve mines c. Number of Endermen killed d. Sword coating 27. Which would be a good hypothesis for this experiment? a. I think that the diamond sword will kill more Endermen. b. If I coat my sword in iron, then I will kill more Endermen. c. If I kill more Endermen, then the iron sword is stronger. d. People who use diamond swords are wasting their money because iron works just as well. 28. What would be a good problem question for this experiment? a. What is effect of Endermen kills on sword type? b. What is the effect of sword type on the number of Endermen killed? c. Is there a relationship between swords and Endermen death? d. There are too many Endermen.
5 Use the following scenario to answer questions Mr. Archer loves playing Pokemon GO! He believes that by playing Pokemon GO, he will lose weight at a faster rate. To test this idea, Mr. Archer walks the path at Veteran s Park for 30 minutes a day for 2 weeks without playing the game. After this 2 week period, he plays Pokemon GO at Veteran s park for 30 minutes a day for 2 weeks. He records his weight every Monday, Wednesday, and Friday for the total 4 week period. 29. What are 3 constants Mr. Archer needs to have in this experiment? a. Amount of time, location, and Mr. Archer b. Mr. Archer, rate of weight loss, and Veteran s Park c. Pokemon GO, frequency of weight checking, and season d. Pokemon GO, Veteran s Park, and rate of weight loss 30. What is another variable that could affect Mr. Archer s weight loss? a. His cell phone b. His diet c. Number of students at school d. Who he walks with 31. What is the independent variable in this experiment? a. Location b. Playing Pokemon GO c. Rate of weight loss d. Type of shoes 32. What is the dependent variable in this experiment? a. Location b. Playing Pokemon GO c. Rate of weight loss d. Type of shoes Use the following scenario to answer questions Did you know that the bottle flipping craze is actually full of science? Sgt. Pitts wants to see if the volume of water in the bottle affects how the bottle lands when it is flipped. He fills one plastic bottle 1/3 of the way with water, another 2/3 full, and another one completely full. He flips each bottle 5 times and records if the bottle landed upright or fell over each time. 33. What is the dependent variable in this experiment? a. Amount of water in bottle b. Number of time bottle flips over c. Number of times bottle lands upright d. Type of water bottle 34. What is the independent variable in this experiment? a. Amount of water in bottle b. Number of time bottle flips over c. Number of times bottle lands upright d. Type of water bottle
6 35. What is a good hypothesis for this experiment? a. If Sgt. Pitts fills the bottle 1/3 of the way full, then the bottle will land upright 80% of the time. b. If Sgt. Pitts flips each bottle 5 times, then the volume of the water in the bottle will affect how it lands. c. I think that the bottle will land upright if Sgt. Pitts fills the bottle 2/3 full. d. Why would Sgt. Pitts flip water bottles anyway? 36. Based on the data table, what conclusion should Sgt. Pitts make based on his experiment? Volume Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 1/3 full Upright Upright Upright Fell over Upright 2/3 full Fell over Fell over Upright Upright Fell over Full Fell over Fell over Fell over Fell over Fell over a. Filling the bottle 1/3 full of water increases the chances of the bottle landing upright when flipped. b. Filling the bottle 2/3 full of water increases the chances of the bottle landing upright when flipped. c. Sgt. Pitts has mad bottle flipping skills d. The volume of water has no effect on the way a flipped water bottle lands Use the following scenario to answer questions During the Highland East Junior High 50 th Hunger Games, tributes can only use certain forms of camouflage. They can dress in the Cougar mascot suit, dress as a teacher, or dress like a lunch lady. Bob wants to see which type of camouflage keeps him hidden the longest. 37. What is the independent variable in this experiment? a. District tributes are from b. Number of other tributes c. Number of times he is found d. Type of camouflage 38. What is the dependent variable in this experiment? a. District tributes are from b. Number of other tributes c. Number of times he is found d. Type of camouflage 39.
