CERs - ANDREW GLEED | Library

In science, a strong conclusion is essential to communicating your findings clearly. When writing a conclusion, you can identify three main components: claim, evidence, and reasoning. The claim is the main point or argument you are trying to convey, while the evidence includes the facts, data, or observations that support your claim. Finally, reasoning explains how the evidence links to the claim, providing a logical connection that helps others understand why your claim is valid.

For example, suppose you conducted an experiment to determine whether plants grow faster in sunlight or shade. Your claim might be, “Plants grow faster in sunlight.” The evidence could be the measurements you took, showing that plants in sunlight grew an average of 20 centimeters, while plants in shade only grew 10 centimeters. Your reasoning would explain why sunlight is crucial for photosynthesis, the process plants use to convert light energy into food.

Together, these elements create a well-rounded conclusion that not only states your findings but also backs them up with solid proof and logical explanation. This approach not only strengthens your argument but also enhances your overall scientific communication skills, making your conclusions more persuasive and understandable to others.

Read the CER below and highlight the claim.

When the mass of a ball increases, crater diameter increases as well. It was observed that when the ball with a mass of 20 grams was dropped into the sand, the average crater diameter was 5 cm. When the ball with a mass of 67.5 grams was dropped into the sand, the average crater diameter was 8 cm. The ball with more mass had an average crater diameter that was 3 cm wider. When the mass of a ball increases, crater diameter increases as well. The crater diameter increases because the ball with more mass has more kinetic energy as it is falling into the container of sand.
