8-28-17 Results of Scientific Inquiry; Scientific Theory vs. Scientific Law
Do Now: Answer the following question in your Science Notebook. Why might you engage in scientific inquiry? We do so to find answers to questions about nature. 2. What questions are asked and answered in many scientific investigations? Who? What? When? Where? How?
Take notes of the following slides, especially underlined items! Standards: SC.7.N.3.1, SC.7.N.1.2 Lesson Objectives: I can select from a list if a statement is a theory or a law. I can define the terms theory and law.
Results of Scientific Inquiry In science, you perform scientific inquiry to find answers to questions. There are many outcomes of scientific inquiry, such as technology, materials, and explanations.
Results of Scientific Inquiry: Technology Technology : the practical use of scientific knowledge, especially for industrial or commercial use . Examples include televisions, MP3 players, and computers. The C-Leg, shown here, is a prosthetic leg with sensors that anticipate the user’s next move, preventing him/her from stumbling or tripping.
Results of Scientific Inquiry: New Materials Another possible outcome of an investigation are new materials. For example, scientists have developed a bone bioceramic , a synthetic bone that mimics the natural bone’s structure. The bioceramic can be shaped into implants to replace missing bone.
Results of Scientific Inquiry: Possible Explanations Many times, scientific investigations answer the questions: who, what, when, where, or how . For example, who left fingerprints at a crime scene? When should fertilizer be applied to plants? Where can I find new species of organisms? In 2007, scientists discovered a new species of tree frog in Colombia’s tropical rain forests.
Lesson 1-4 Partner Check: Discuss with your shoulder partner. What are the results of scientific investigations? Answer: New technology, new materials, and possible explanations of natural phenomena.
Scientific Theory & Scientific Law Scientists often repeat investigations to verify that the results for a hypothesis are correct. This can lead to a scientific theory. Scientific theory: an explanation of observations or events based on knowledge gained from many observations and investigations. Teoria cientifica : explicacion de observaciones o eventos con base en conocimiento obtenido de muchas observaciones e investigaciones.
Scientific Theory & Scientific Law Example Scientific Theory: Cell theory . About 300 years ago, scientists began looking at samples of organisms through the first microscopes. They noticed they were made of tinier units, or cells. As more scientists observed cells in other organisms, their observations became known as the cell theory. This theory explains that all living things are made of cells.
Scientific Theory & Scientific Law Scientific law: a rule that describes a pattern in nature. ley cientifica : regla que describe un patron dado en la naturaleza . A scientific law describes a pattern or an event in nature that is always true. A scientific theory might explain how and why an event occurs. But a scientific law states only that an event in nature will occur under specific conditions .
Scientific Theory & Scientific Law Scientific Law Example: The law of conservation of mass This law states that the mass of materials will be the same before and after a chemical reaction. This scientific law does not explain why this occurs – only that it will occur.
Comparing Scientific Theory & Scientific Law Scientific Theory Scientific Law Based on repeated observations and scientific investigations. Observations of similar events that have been observed repeatedly. If new information does not support a scientific theory, the theory will be modified or rejected. If many new observations do not follow the law, the law is rejected. Attempts to explain why something happens States that something will happen. Usually more complex and might contain many well-supported hypotheses. Usually contains one well-supported hypothesis that states that something will happen.
Independent Student Work: Complete “Results of Scientific Inquiry/Scientific Law & Scientific Theory” Worksheet You should have picked this worksheet up when you came in the classroom. If you haven’t raise your hand for permission to get out of your seat (Rule 3). Only complete the front page (Results of Scientific Inquiry/Scientific Law & Scientific Theory) If you don’t finish it in class, this will be your homework. If you finish early, silently read a book.
