Science is the process of understanding the natural world through observation and experimentation. Scientists use the scientific method to solve problems by forming a hypothesis, designing experiments to test the hypothesis, observing results, and drawing conclusions. Technology applies scientific knowledge to create useful tools and machines. The scientific method involves preparing by identifying a problem and forming a hypothesis, planning an experiment to test the hypothesis, conducting the experiment and observing results, and concluding by analyzing results and determining if the hypothesis was supported.

1. Chapter 1 The Nature of Science

2. Science and Technology Section 1-1 H.W. pg.12 Ques. 1,2 What is Science Science is the process of trying to understand the world around you. ● What do you call someone who practices science? A scientist ● We use science to create technology. Technology is the use of knowledge learned through science Examples of Technology Computers, machines, cars.

3. Doing Science Section 1-2 H.W. Pg. 10 Ques. 1-10 Whenever you do science you want to solve a problem . What are some problems that you can solve? - Why does a plant grow?, How do we use oxygen? In order to solve your scientific problem you must conduct an experiment , which a series of tests that you perform in order to solve your problem.

4. Conducting Experiments In order to conduct an experiment you must use the Scientific Method . The scientific method is a series of steps taken during an experiment. • There are four stages of the scientific method: Prepare Plan Do Conclude and apply

5. Scientific Method 1) Prepare : - First Identify the problem (what you want to solve). Next form a hypothesis . What's a hypothesis ? A hypothesis is a statement that can be tested about a problem. (Why you think this problem exists). Lets think of some problems and hypothesis's.

6. Scientific Method (continued) 2) Plan : Here we design an experiment in order to test our hypothesis. 3) Do : Test our hypothesis & Observe and record the results of our experiment. 4) Conclude and Apply : Analyze our results (why our results occurred) & Draw conclusions (what can say about our experiment. Did it work? Why, Did it fail? Why? And if so, what can we do next time to make it work?

7. Important things to consider when using the scientific method Trials, variables, and Data Tables Trials are repeated experiments, performed in order to make sure that your results are consistent. (the more trials you perform the truer the results.) Why else would you perform more than just one trial? -Human error, faulty material

8. Variables are factors in an experiment that can change. (Watering plants) Data Tables- these organize your observations and results into columns and rows. We make data tables in order to keep track of results and be able to communicate them to others. Styrofoam presentation!
