Question 1:

Which of the following is an example of making a prediction based on a hypothesis?

A) If a plant is given more sunlight, it will grow taller.
B) If the temperature increases, ice will melt.
C) If the speed of a car decreases, it will cover less distance.
D) If a person eats a healthy diet, they will have higher energy levels.

Show Answer

Explanation: The correct answer is A) If a plant is given more sunlight, it will grow taller. Making a prediction based on a hypothesis involves stating the expected outcome or result based on the proposed relationship between variables. In this case, the hypothesis suggests that more sunlight will lead to increased plant growth, and the prediction is that the plant will grow taller when given more sunlight.

Question 2:

Which of the following is an example of a prediction based on a hypothesis?

A) If the price of a product decreases, demand will increase.
B) If it rains, people will use umbrellas.
C) If the air temperature decreases, water will freeze.
D) If a person exercises regularly, their fitness level will improve.

Show Answer

Explanation: The correct answer is A) If the price of a product decreases, demand will increase. Making a prediction based on a hypothesis involves stating the expected outcome or result based on the proposed relationship between variables. In this case, the hypothesis suggests that a decrease in price will lead to an increase in demand, and the prediction is that when the price of a product decreases, the demand for it will increase.

Question 3:

Which of the following is an example of making a prediction based on a hypothesis?

A) If the temperature rises, snow will melt.
B) If a person drinks caffeine, they will feel more alert.
C) If the concentration of a chemical increases, the reaction rate will decrease.
D) If a plant is watered regularly, it will have healthier leaves.

Show Answer

Explanation: The correct answer is B) If a person drinks caffeine, they will feel more alert.

Question 4:

Which of the following is an example of a prediction based on a hypothesis?

A) If the humidity increases, the rate of evaporation will decrease.
B) If a person wears warm clothes, they will feel cold.
C) If the air pressure decreases, the balloon will expand.
D) If a person exercises regularly, their body weight will decrease.

Show Answer

Question 5:

Which of the following is an example of making a prediction based on a hypothesis?

A) If the temperature drops, ice will freeze.
B) If a person eats unhealthy food, they will become healthier.
C) If the concentration of a substance increases, its density will decrease.
D) If a person studies hard, their grades will decrease.

Show Answer
