A 2000+ slide PowerPoint presentation from www.sciencepowerpoint.com becomes the roadmap for an amazing learning experience. Complete with homework package, built-in activities with directions, built-in quizzes, unit notes, follow along worksheets, answer keys, video links, review games, rubrics, and much more. Also included are directions on how create a student version of the unit that is much like the teachers but missing the answer keys, quizzes, PowerPoint review games, hidden box challenges, owl, and surprises meant for the classroom. This is a great resource to distribute to your students and support professionals and will only take you a few minutes to create. This is a great introductory unit that covers science topics associated with Lab Safety, Magnification, Base Units of the Metric System, Scientific Method, Inferences, and Observation Skills (See list below for more topics covered). This unit includes an interactive and engaging PowerPoint Presentation of 2000 slides with built in class notes (Red Slides), lab activities, project ideas, discussion questions, assessments (Quiz Wiz), and challenge questions with answers. Text is in large print (32 font) and is placed at the top of each slide so it can seen and read from all angles of a classroom. A shade technique, as well as color coded text helps to increase student focus and allows teacher to control pace of the lessons. Also included is a 10 page assessment / bundled homework that chronologically follows the slideshow for nightly homework and end of the unit assessment, as well as a 9 page modified assessment. 14 pages of class notes with images are also included for students who require modifications, as well as answer keys to both of the assessments for support professionals, teachers, and home school parents. Several video links are provided and a slide within the slideshow cues teacher / parent when the videos are most relevant to play. Video shorts usually range from 2-7 minutes. One PowerPoint review game (125+ slides)is included. Answers to the PowerPoint review game are provided in PowerPoint form so students can self-assess. Lastly, several class games such as guess the hidden picture beneath the boxes, and the find the hidden owl somewhere within the slideshow are provided. Difficulty rating of 5 (Ten is most difficult) Thank you for time and if you have any questions please feel free to contact me at www.sciencepowerpoint@gmail.com. Best wishes. Teaching Duration = 4+ Weeks Sincerely, Ryan Murphy M.Ed Science PowerPoints

• Please drop an old penny and a new penny 15 times each from a height of 30 cm onto a hard surface and listen to the sound it makes.
• Example of tester organizing trials. 1 2 3 4 5 6 7 8 9 10 Old Old Old Old Old New New New New New Trials Old New
• Activity! Times Have Changed – Choose a partner for this project that was not next to you during random order collection. – Keep your random test order hidden from your new partner / listener. – Listener should keep eyes closed during each drop and until pennies have been collected. • Old and new pennies look differently. – Tester and listener must communicate for each drop. Tester says “dropping” and listener says “drop away.” Listener can open eyes when tester says pennies have been collected and mark their guess on the listener spreadsheet. Copyright © 2010 Ryan P. Murphy
• Problem: Can you determine an old penny from a new penny by the sound it makes when dropped? –Score your own sheet • (10 pts for correct response) –Gather the entire classes scores to obtain average / mean. • Add all of the scores and divide by the number of students. – What was the average grade / mean (%) • Do our results answer the problem?
• Continuation (Optional) Finding standard deviation and variance. – Standard variation is the square root on the variance. – Variance: The average of the squared differences from the mean.
• Statistical Methods – The mean / average was… – Everyone calculate how far away their data was from the mean / average. • Ex.) The mean was 80 and I got 60 so I was 20 from the mean. – To calculate the variance, take each difference, square it, and then average the result as a class. • Ex) 22 + 4.52 + 1.52 + 3.52 + (rest of class) Divide by total # of students = variance
• The Standard Deviation is just the square root of the Variance. – So square the variance that we found. Example… 6523 = 80.76% We now have a standard to show which scores are high and low and to help answer our problem.

• Activity! (Optional) Making Goop • Directions in video and on next slide. • http://www.youtube.com/watch?v=48- DU0kQtPg
• Materials – Glue bottle (4oz) – 2 mixing bowls – Water – Mixing spoon – Measuring Cups – Borax – Measuring spoon – Sealable Bag
• Procedure: – 1.) Squeeze glue into bowl. – 2.) Fill glue bottle with water, cap, mix, and pour into the glue in bowl. – 3.) Stir and add desired food coloring. – 4.) Set that bowl aside. – 5.) In new bowl mix 1 cup of water with 1 tablespoon of borax and stir. – 6.) Add 1/3 a cup of borax and water mixture into a bowl and stir. – 7.) Slowly add the contents from the glue bowl into the borax bowl while you stir. – 8.) Pick up goop and work it with your hands. Put in plastic bag and clean up area. – 9.)Once area is clean you can play with goop.
• Goop is a polymer you can make from white glue and borax. – Borax is a cleaning agent and natural mineral composed of sodium, boron, oxygen and water. – The Elmer’s glue is a long-chained polymer (Poly Vinyl Acetate), meaning it is a set of molecules that are linked together in a long chain. – When added together, the borate ions bond with water molecules. These long polymers link together to form a matrix that is not very strong. – This why goop is stretchable and considered a Non-Newtonian Fluid. High Viscosity.

  • 241. • Problem: Can you determine an old penny from a new penny by the sound it makes when dropped? –Score your own sheet • (10 pts for correct response) –Gather the entire classes scores to obtain average / mean. • Add all of the scores and divide by the number of students. – What was the average grade / mean (%) • Do our results answer the problem?
  • 242. • Continuation (Optional) Finding standard deviation and variance. – Standard variation is the square root on the variance. – Variance: The average of the squared differences from the mean.
  • 243. • Statistical Methods – The mean / average was… – Everyone calculate how far away their data was from the mean / average. • Ex.) The mean was 80 and I got 60 so I was 20 from the mean. – To calculate the variance, take each difference, square it, and then average the result as a class. • Ex) 22 + 4.52 + 1.52 + 3.52 + (rest of class) Divide by total # of students = variance
  • 244. • The Standard Deviation is just the square root of the Variance. – So square the variance that we found. Example… 6523 = 80.76% We now have a standard to show which scores are high and low and to help answer our problem.

  • 264. • Materials – Glue bottle (4oz) – 2 mixing bowls – Water – Mixing spoon – Measuring Cups – Borax – Measuring spoon – Sealable Bag
  • 265. • Procedure: – 1.) Squeeze glue into bowl. – 2.) Fill glue bottle with water, cap, mix, and pour into the glue in bowl. – 3.) Stir and add desired food coloring. – 4.) Set that bowl aside. – 5.) In new bowl mix 1 cup of water with 1 tablespoon of borax and stir. – 6.) Add 1/3 a cup of borax and water mixture into a bowl and stir. – 7.) Slowly add the contents from the glue bowl into the borax bowl while you stir. – 8.) Pick up goop and work it with your hands. Put in plastic bag and clean up area. – 9.)Once area is clean you can play with goop.
  • 266. • Goop is a polymer you can make from white glue and borax. – Borax is a cleaning agent and natural mineral composed of sodium, boron, oxygen and water. – The Elmer’s glue is a long-chained polymer (Poly Vinyl Acetate), meaning it is a set of molecules that are linked together in a long chain. – When added together, the borate ions bond with water molecules. These long polymers link together to form a matrix that is not very strong. – This why goop is stretchable and considered a Non-Newtonian Fluid. High Viscosity.
