Scientists research and make observations(观察). They also do experiments(实验). Here are the steps for the scientific method. First, think about what things make you curious to learn more. Make an observation. For example, you may have noticed that mold(霉) grows on most kinds of food. Then, you may ask yourself a question, “What conditions 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 make the mold grow best?” It helps you focus on what you want to know. Next, you need to make a hypothesis(猜想). It comes from what you already know. So here, you may guess that mold grows best in cold and dark conditions. After that, it’s time to run an experiment to test your hypothesis! You could put the food in different conditions to see what will happen. Finally, the results come out and you’ll draw a conclusion(结论)—Are the results the same as your hypothesis or different from it? 首页 目录 回归教材 · 知识梳理 课堂达标 · 高效提能 Lab Report Name: Kevin Somers Date: May 24,2025 Project Title: Testing How Mold Grows Question: I wonder what conditions make mold grow best.
