Question

1. you want to see how fast your turtle can move after he eats hot peppers. you feed him his regular food and measure how fast he moves over 3 meters. then you feed him hot peppers and measure how fast he moves over 3 meters. independent- dependent- control/constant- 7. you want to find the best size of kite flies the longest. you make 5 different sized kites and set up a wind tunnel in the gym. you measure the time it takes each kite to get into the air and how long they stay up. independent- dependent- control/constant- 8. you want to see what kind of milkshake stays coldest the longest. you make 3 milkshakes with different amounts of ice and measure the temperature of each. you wait 45 minutes and measure the temperature again. independent- dependent- control/constant- 9. you are running an experiment in science to test which bubble gum has the largest bubble. you choose 4 types of bubble gum and chew each piece 50 times, then blow bubbles and measure them. independent- dependent- control/constant- 10. you are trying to make the best formula for gak. you think that changing the amount of borax will make the most difference. you make 4 different mixtures of gak using different amounts of borax, them measure how much each gak will stretch. independent- dependent- control/constant-

Explanation:

• In an experiment, the independent variable is what is changed, the dependent variable is what is measured as a result of the change, and the control/constant is what is kept the same throughout.
• For question 6: The food type (regular food or hot - peppers) is changed, so it's the independent variable. The turtle's speed over 3 meters is measured, making it the dependent variable. The distance of 3 meters is kept the same, so it's the control/constant.
• For question 7: The size of the kite is changed, so it's the independent variable. The time to get into the air and the time it stays up are measured, making them the dependent variables. The wind - tunnel in the gym (the environment) is kept the same, so it's the control/constant.
• For question 8: The amount of ice in the milkshakes is changed, so it's the independent variable. The temperature of the milkshakes is measured, making it the dependent variable. The waiting time of 45 minutes is kept the same, so it's the control/constant.
• For question 9: The type of bubble - gum is changed, so it's the independent variable. The size of the bubble is measured, making it the dependent variable. Chewing each piece 50 times is kept the same, so it's the control/constant.
• For question 10: The amount of Borax in the gak mixtures is changed, so it's the independent variable. How much the gak stretches is measured, making it the dependent variable. The process of making the gak (other than the Borax amount) is kept the same as much as possible, so it's part of the control/constant.

Answer:

1. Independent - Type of food (regular or hot peppers)

Dependent - Turtle's speed over 3 meters
Control/constant - Distance of 3 meters

1. Independent - Size of the kite

Dependent - Time to get into the air, time it stays up
Control/constant - Wind - tunnel in the gym

1. Independent - Amount of ice in the milkshakes

Dependent - Temperature of the milkshakes
Control/constant - Waiting time of 45 minutes

1. Independent - Type of bubble - gum

Dependent - Size of the bubble
Control/constant - Chewing each piece 50 times

1. Independent - Amount of Borax in the gak mixtures

Dependent - How much the gak stretches
Control/constant - The process of making the gak (other than Borax amount)
