In the scientific method, you decide to find out the answer to this questions through research and experiments.   Step 3: Conduct Research Now you want to understand the topic better. Maybe this topic was researched by someone before, and the answers are available in a book, video, or scientific article. So you first look for available information on the topic.   Step 4: Form a Hypothesis A ‘hypothesis’ is an educated guess or a possible explanation. Once you have a hypothesis, you can then design an experiment to test it and see if your prediction is correct or no

  Grade 5                                 Science                                    Unit 1 Lesson 1   "Matter is everything around us that takes up space and has weight. It's what everything is made of. Think about the air you breathe, the water you drink, and the desk you sit at – they're all made of matter. Matter can exist in different forms, like solids, liquids, and gases. Solids are things you can touch and feel, like books or toys. Liquids, like water and juice, can flow and take the shape of their container. Gases, like the air we breathe, are all around us even though we can't see them. So, matter includes everything from the tiniest grain of sand to the air we breathe!"
