| What is science? | Science is the study of the natural world: its history and how it works. It involves taking observations, turning them into questions and thoughts and experimenting to find the answer. Science delves deeper into the existence of life: how it works and where it came from. |
| Describe the scientific method, including dependent and independent variables. | The Scientific Method is a process designed to come to a conclusion about an observation or thought through experimentation. It begins with an observation, which is used to formulate a question. That question is the basis for an experiment. A hypothesis, or prediction (if, then) is created based on the question. From there, different variables in the experiment, or trials, are gathered. An independent variable, or manipulated variable, is changed with each trial. The dependent variable depends on the independent variable, and is often what is being measured, or the result of the independent variable. Constants stay the same for each trial. A control is a trial that is used to compare data. The experiment follows a set of specific steps known as the procedure. The data is the evidence collected, is used to draw conclusions and is analyzed through Error Analysis and relating it to your predictions. The conclusion stated the final outcome of the experiment and explains the experiment. This method isn't just used in science, but to inquire about things in our daily life. |
| Why is a control needed? | A control (group) is needed in order to compare the trials with the independent variable manipulated and the trial without. In organism studies, this is important because giving one thing to an organism in different amounts may completely differ from the results of the organism without that thing. |
| Qualitative vs. Qualitative Data | Quantitative data involves numerical values (quantities), measurements or amounts. This type of data is more accurate than Qualitative data which is based on observations. An example of this type of data would be to say that the liquid turns white when HCl is added. This type isn't numbers or amounts, but could be colors, texture, viscosity, appearance, etc. |
