Lesson 3 Doing Science
1 like239 views
This document provides guidance for a lesson on doing science. It discusses key concepts like scientific questions being answered through descriptive or experimental research. Models are used to test difficult ideas by saving time and money. A hypothesis is an idea that can be tested, and sometimes experiments disprove the original hypothesis, requiring a new one. Well-planned experiments have a control and vary only one factor at a time. Careful organization and planning are important when solving any problem scientifically. The lesson covers solving problems through scientific methods, using equipment and models, drawing conclusions, and experimental research design.
Lesson 3 Doing Science
- 1. Lesson 3: Doing Science Mathematics, Science, Technology 2-3 Days Scientific questions can be answered by descriptive research or experimental research. Models save time and money by testing ideas that are Grade/Level: too difficult to cary out. Time Frame: Models cannot completely replace experimentation. Subject(s): A hypothesis is an idea that can be tested. Sometimes experiments don't support the original hypothesis, and a new one must be formed. In a well planned experiment, there is a control and only one variable is changed at a time. All other factors are kept constant. No one scientific method is used to solve all problems. Organization and careful planning are important when trying to solve any problem. Topics: 1. Solving Problems: scientific methods are the steps followed to solve a problem. Descriptive research is used when experiments are impossible to use. 2. Equipment, Material & Models: models are important tools in science. The International System of Units (SI) is used exclusively to take scientific measurements. Data is collected, recorded, and organized. 3. Draw Conclusions: scientist look for trends in data, then communicate their findings. 4. Experimental Research Design: experiments start with hypothesis. Variables are factors that are changed. Controls are samples that are not changed. Conclusions are drawn. Research is communicated to other scientists. Notes: Curriculum Connections: Environmental Science- Clean Water Act. History- 1854 cholera epidemic, Local Connection- Canton/Paper Mill Wastewater Treatment Facility (Potential Field Trip) Misconception: There is "ONE" method of scientific investigation... a bunch of steps if you will. Understandings: Using scientific methods and carefully thought-out experiments can help you solve problems. Examine the steps used to solve a problem in a scientific way. Explain how a well designed investigation is developed. Knowledge and Doing Science Skills: 2.1. Examine the steps used to solve a problem in a scientific way 2.2. Explain how a well designed investigation is developed 2.3. Differentiate between scientific theory and scientific law 2.4. Explain what scientific literacy is and why it is important.

- 2. Essential Questions: What are some questions to think about when planning an investigation? Why is it important for scientists to communicate their data? What is an experimental control? Why do scientists use models? What three steps might scientists use when designing an investigation to solve a problem? Why is it important to carefully identify the problem being solved? Why is contrary evidence to a hypothesis not a failure of an experiment? Learning Experiences Bell Ringer: Nobel Prize for Cookies Continue Cornell format notes: begin "Doing Science".

Organize class into groups of three. Ask students to design an experiment to test the effectiveness of various glass cleaners. Have groups produce an experimental plan, including materials, methods of analysis, procedures, and variables. 2. Organize students into pairs. Have each pair write on an index card a hypothesis about any topic. Have them switch cards and discuss whether a model could be created to carry out the experiment.
