Surrounded by Science How is math used in science?
Scientific Notation • Scientists developed a method to make very large and very small numbers more manageable using coefficients and exponents based on the powers of 10. • 123,000,000,000 is written 1.23x 1011 • 1.23 is the coefficient and 1011 is the exponent or the power of 10. • Very small numbers are written like this 0.00000000804 = 8.04 x 10-9 (negative exponent)
Writing Scientific Notation • Put the decimal after the first digit and drop the zeroes (do not drop number 1-9 that follow the decimal) • To find the exponent, count the number of places from the decimal to the end of the number. • You try it! • 238,000,000,000 = • 78,000,000 = • 0.000000000097 =
Measurement – English Units Length • 1 foot (ft) = 12 inches (in) • 1 yard (yd) = 3 ft = 36 in • 1 mile (mi) = 5280 ft Time • 1 minute (min) = 60 seconds (s) • 1 hour (h) = 60 min • 1 day = 24 h Weight • 1 pound (lb) = 16 ounces(oz) • 1 ton = 2000 lb Volume • 1 cup (c) = 8 fluid ounces (fl oz) • 1 pint (pt) = 16 fluid ounces (fl oz) • 1 quart (qt) = 2 pt • 1 gallon (gal) = 4 qt

Measurement - Metrics Length • 1 centimeter (cm) = 10 millimeter (mm) • 1 meter (m) = 100 cm • 1 kilometer (km) = 1000 m Weight • 1 centigram (cg) = 10 milligram (mg) • 1 gram (g) = 100 cg • 1 kilogram (kg) = 1000 g Volume • 1 centiliter (cl) = 10 milliliter (ml) • 1 liter (L) = 100 cl • 1 kiloliter (kl) = 1000 L
Percents • To find out what percent of one number is of another, divide the part by the whole. • What percent of 150 is 76? • P x 150 = 76 • So, 76 is about 51% of 150 Where do you use percent in science?
Graphs, Charts, Tables • You graph in science to show your results – line graphs, scatter plots, spread sheets, bar graphs, charts, tables. • You need to know the difference between the independent variable and dependent variable and use them appropriately in a correct type of graphic.
Converting Temperature Scales • Celsius to Fahrenheit • F= (9/5 x C) + 32 • Fahrenheit to Celsius • C = 5/9(F-32) It’s Your Turn!
Surrounded by Science Incorporating Math & Science According to the Research
Surrounded by Science • Of the 20 fastest growing occupations projected through 2010, 15 of them require substantial math and science preparation (National Bureau of Labor Statistics) • Public opinion calls for better math and science preparation in schools and 85% want this to be a top priority in our states (Bayer Corporation)
Surrounded by Science Strategies for Teaching Science
Surrounded by Science • Understanding vs. Knowing • What’s the difference? • How do you know you really understand it?
Surrounded by Science Real Understanding and Apparent Understanding John Dewey was visiting a class that was studying the structure of the earth. He asked…What would you find if you dug a hole to the center of the earth? The students were silent. You’re asking the wrong question, said the teacher. Turning to the class the teacher asked, What is the state of the center of the earth? In unison the class responded…Igneous fusion.
Surrounded by Science Apparent Understanding • Delivery of the right word, the right definition, the correct formula. Real Understanding • using learning in new ways. (Benjamin Bloom) • the ability to think and act flexibly with what one knows. (David Perkins)

Surrounded by Science Let’s Apply! • Use hands-on demonstrations & experiments to help students “see” science and math concepts at work • Use demos & experiments to help students apply their understanding to new situations • Use resources to examine and/or dispel common misconceptions
Surrounded by Science The Scientific Method • Observe - make observations about something in the world. • Hypothesize - try to come to some sense about your observations and formulate a hypothesis or theory for why things are this way. • Test the hypothesis - come up with a method to test the validity of your hypothesis through an experiment that will confirm or deny the hypothesis and based on the results of the test on the hypothesis, either modify the theory or accept it as being likely.
Surrounded by Science SCIENTIFIC METHOD State your findings Conduct an experiment to test your hypothesis Design an experiment to test your hypothesis Make a prediction (hypothesis) Identify a problem or question Observe nature carefully

Surrounded by Science What to do if the experiment didn't work • OK, so it happens. But we are prepared! Scientific experimentation is not an exact science (excuse the pun). That's what experimentation is all about. Follow these 5 simple steps if one of the experiments does not work. • Carefully repeat the experiment again • Carefully repeat the experiment again • Carefully repeat the experiment again • Ask the instructor regarding your question/problem with the experiment • Carefully repeat the experiment again • Following these 5 steps will almost always guarantee success. You also get a more precise feel for how a real scientist conducts experimentation.
Surrounded by Science Other Teaching Strategies That Work • Tell your students what “Big Ideas” they will be learning • Show relationships to real-world experiences • Start classes with short activity that requires students to access previously learned information or background knowledge • Build into each class meeting, time for students to apply and practice, under your guidance, what they are learning • To get students to read the material and attend to it, use before reading, during reading, and after reading activities to make reading an active process.
