| Branches of Science | >Physics >Biology >Chemistry >Geology >Astronomy >Ecology |
| Observations | #Qualitative (L for letters) #Quantitative (N for numbers) #Observations involve measurements. |
| Reporting | A scientific report must contain the following in this order: >Aim >Hypothesis (optional) >Equipment or materials >Method >Results and observations >Discussion or Analysis >Conclusion |
| Aim | What you intend to do or achieve in an experiment. |
| Hypothesis | An idea of what you think may happen, an educated guess. |
| Equipment or materials | All the important equipment and chemicals needed in the experiment, the sizes must be included |
| Method | A detailed list of what was done in the experiment, to allow another scientist to repeat the experiment you must include quantities and the exact order in which things were done. A diagram can be used to help explain |
| Results and Observations | A complete list of measurements and observations you took in the experiment. It is clearer if you display them in a table. Headings and units (kg & mL) must be included |
| Discussion or Analysis | The scientists discussion includes: Problems encountered in the experiment, What was done to overcome problems, Your view on what the results indicate about the experiment, What you found out in the experiment from other sources. It can include: Graphs, Ideas for further experiments. |
| Conclusion | A summary of what the scientist has found out in the experiment, the conclusion should be short and must relate or refer to the aim. |
| Measurement | Scientists use the metric system when taking measurements, measurements must be accurate and with care mistakes can be avoided. An error in science is unavoidable. |
| Errors | Errors are unavoidable and are slight changes in measurements. A common error in science is mixing up or not putting in the units. Parallax errors are caused by not having your eye directly in line with the measurement. A zero error is when the measuring device reads value when nothing has been measured yet. |
| Beam Balance | A beam balance is a measuring device used to determine the mass of an object. The mass is how much matter there is in an object and is sometimes incorrectly called weight. |
| Bunsen Burner | A Bunsen Burner was invented by Robert Bunsen in the 1800's. It is used in science to heat things up, it can sometimes be very dangerous. |
| Collar | The collar is a part of a Bunsen burner that can be opened to let oxygen in to change the yellow safety flame to the blue hotter flame. |
| Barrel | The barrel is the long metal tube that the gas travels up to come out the top of the Bunsen burner. |
| Gas hose | The gas hose is connected to the base of the Bunsen burner and the other end is connected to the gas switch. The gas travels through this pipe to the Bunsen burner which converts this to fire. |
