Why is it important to follow a systematic process, such as asking questions, forming a hypothesis, conducting experiments, and analyzing data, when conducting scientific investigations?

Multiple Choice

Which of the following is an example of an independent variable in an experimental design scenario?

• The amount of sunlight a plant receives

• The height of the plant

• The number of leaves on the plant

• The color of the plant's flowers

Multiple Choice

What is the main purpose of experimental design in scientific research?

• To determine the effect of one variable on another variable

• To memorize scientific facts

• To create new scientific laws

• To avoid using variables

Multiple Choice

Which of the following statements best describes a hypothesis in an experiment?

• A prediction about what will happen, often written as an 'If... then...' statement

• A variable that is kept the same

• A measurement taken during the experiment

• A summary of the experiment's results
