Evgesh-ka [11]

Answer:

The statement that is incorrect is :

Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.

Explanation:

A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.

joja [24]

Answer:

1. My toaster doesn't toast my bread. --> Observation

2. Why doesn't my toaster work? ---> ask questions

3. There is something wrong with the electrical outlet. ---> Hypothesis

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it. ---> Prediction

5. I plug my coffeemaker into the outlet. ---> Experiments

6. My coffeemaker works. ---> Result of experiment

Note: The question is missing some parts. The complete question is given below.

In the example below the scientific method is used to solve an everyday problem. Match each component to the appropriate step in the scientific method:

1. My toaster doesn't toast my bread.

2. Why doesn't my toaster work?

3. There is something wrong with the electrical outlet

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it.

5. I plug my coffeemaker into the outlet.

6. My coffeemaker works.

Explanation:

The scientific method involves the following; observations, ask questions, form a hypothesis, make predictions, design experiment to test the hypothesis, obtain results, analyze results, draw conclusions.

1. My toaster doesn't toast my bread is an observation made by the person.

2. The person then proceeds to asks questions based on the observation; Why doesn't my toaster work?

3. The next step involves making a hypothesis to try to explain the observation; "There is something wrong with the electrical outlet"

4. A prediction is then made, which is an expected outcome if the hypothesis is correct; "If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it".

5. Next, an experiment is conducted to test the hypothesis whether it is true or not; "I plug my coffeemaker into the outlet".

6. Results are obtained from the experiment which in this case is, "My coffeemaker works". The result is then analyzed to see whether it supports the initial hypothesis or not. Depending on the results, new hypothesis is made and further experiments conducted until a conclusion is reached.

Lisa [10]

Answer:

The laws of learning make learning more interesting to study.

Explanation:

The learning laws were first proposed by Edward Thorndike, a famous psychologist. According to him, there are three rules of learning, they are- readiness of learning, exercise of learning and effect of it.

To make learning lasting and interesting one should always follow these rules. Readiness states- that learning can be adopted only if the learner is ready to, this can be done by arising their interest on the topic by some pre-activity and making them understand that learning is essential; Exercise states: that the more you revise the more you memorise, it involves consistent practice; law of Effect says: learning can be strong and interesting if its associated with satisfying feeling and is weak when associated with unsatisfying feeling.
