Vocabulary Fill In The Blank

Explanation
The given statement describes the purpose or function of the locker, which is to keep books and valuables safe during the school day.

Explanation
In this investigation, the temperature of the water in the swimming pool is the dependent variable. This means that it is the variable that is being measured or observed and is expected to change as a result of the independent variable, which is not mentioned in the question. The dependent variable is dependent on the independent variable, which is the factor that is being manipulated or controlled in the experiment.

Explanation
In this investigation, the independent variable is the amount of light that the plant is exposed to. The independent variable is the factor that the researcher manipulates or changes in order to observe its effect on the dependent variable, which is the variable being measured or observed. In this case, Jeff is specifically testing the effect of different amounts of light on plant growth, so the amount of light is the independent variable.

Explanation
In this investigation, the boiling point of the water is the dependent variable because it is the variable that is being measured and is expected to change in response to the manipulation of the independent variable, which is the addition of salt to the water. The dependent variable is dependent on the independent variable and is used to determine the effect of the independent variable on the phenomenon being studied.

Explanation
Stephanie investigated the relationship between temperature and the number of times a cricket chirped. To display her data effectively, she would use a graph. A graph allows for a visual representation of the data, with temperature on the x-axis and the number of chirps on the y-axis. This would enable Stephanie to observe any patterns or trends in the data, such as whether the number of chirps increases or decreases with temperature. A graph is a commonly used tool in scientific research to present data in a clear and concise manner.

Explanation
A data table is the best way to display the various factors that Ryan investigated in relation to the health of a stream. It allows for the organization and presentation of data in a clear and structured manner, making it easier to analyze and compare the different factors. A data table can provide a comprehensive overview of the data collected, allowing for easy identification of patterns or trends, and facilitating further analysis and interpretation.

Explanation
In this investigation, Sean is trying to determine which type of food causes hamsters to gain the most weight. To do this, he needs to keep one variable constant, which means it should remain the same throughout the investigation. The variable that Sean should hold constant is the amount of food given to the hamsters. By keeping the amount of food constant, Sean can accurately compare the effects of different types of food on the weight gain of the hamsters.

Explanation
This statement suggests that there is a relationship between bacterial growth and temperature, specifically that bacterial growth increases as temperature increases. To determine if this statement is true or not, it can be tested through experimentation. A hypothesis is a proposed explanation or prediction that can be tested and is based on prior knowledge or observations. In this case, the statement serves as a hypothesis that can be tested by conducting experiments to observe the effect of temperature on bacterial growth.

Explanation
If you have an idea that you want to find a solution for, you are at the problem identification stage of the scientific method. This is the initial stage where a problem or question is identified, and the researcher formulates a hypothesis or a potential solution to investigate further. In this stage, the researcher defines the problem clearly and sets the foundation for the subsequent stages of the scientific method, such as conducting experiments and analyzing data.

Explanation
The information collected by Ray about the students' favorite flavor of cola can be best displayed in a data table. A data table is a structured way of organizing and presenting data, where each row represents a different student and each column represents a different attribute or characteristic, in this case, the favorite flavor of cola. This allows for easy comparison and analysis of the data, making it a suitable choice for displaying this type of information.
