  1. MeasurEment 7th Grade Life Science

  2. Learning Goals & Standards Learning Goals: • Apply measurement and conversion skills. Standards: S7CS1: Students will explore the importance of curiosity, honesty, openness and skepticism in science and will exhibit these traits in their own efforts to understand how the world works. • understand the importance of --- and keep--- honest, clear, and accurate records in science. S7CS4: Students will use tools and instruments for observing, measuring, and manipulating equipment and materials in scientific activities. • Use appropriate tools for measuring objects and/ or substances.

  3. How is math and/or science depicted in this picture?

  4. What measurements do we use? Why is measurement important? OPEN DISCUSSION

  5. History of Measurement • Measurements have not always been standard. Many civilizations created systems of measurements that were limited in use. Many of the systems lacked uniformity and weren’t always observed by others. • How do you think ancient civilizations were able to measure items? • What tools would you suspect these ancient civilizations used for measuring? • What do you think would be possible problems with multiple measurement systems? • What are possible solutions to the problem of multiple systems?

  6. History of Measurement Continued • Metric system and the English (standard) system • https://www.youtube.com/watch?v=DQPQ_q59xyw • During ancient periods, what tools where available for measurement? • If you lived during an ancient period, what system would you have developed to promote uniformity? • Obtain a copy of the Measurement Scavenger Hunt Cornell Notes

  7. Measurement Scavenger Hunt: Cornell Notes • Essential Question: What are the English and SI (metric) systems and how do they compare?

  8. Measurement Cornell Notes What is a standard? • A standard is considered a basis of comparison. • Examples: A standard sized football; a standard sheet of paper. • Are there any other examples you can think of?

  9. Measurement Cornell Notes Why is it important to have standard measurement units? • Standard measurement units ensures that all measurements have a set value and may be compared to other measurements. Example: 8 ounces of lotion is the same regardless of the brand purchased. • The English system of measurement was originally based on common objects. • Examples: • Inch= 3 barleycorns laid end-to-end • Yard= Length between the nose and fingertip of an outstretched arm of King Henry I of England • Stone= weight of certain stones determined by individual English cities. • The metric system (System International or SI) was developed by the French, is based on facts of nature and has units that are multiples of 10 of each other.

  10. Measurement Cornell Notes Why is it important to have standard measurement units? • The metric system was developed by the French, is based on facts of nature and has units that are multiples of ten of each other. Examples: • Meter= the distance light travels through a vacuum in 1/299,792,458 of a second. • Centimeter= 1/100 of the length of a meter • Liter= cubic decimeter(10cm length x 10cm width x 10cm height) or 1000 cubic centimeters • Kilogram= Mass of the standard kilogram, a platinum- iridium cylinder kept in Sevres, France • (Note: Students write kilogram on your paper below liter because it is missing from your Cornell Notes handout)

  11. Measurement Cornell Notes Why is it important to have standard measurement units? • Basic SI units and prefixes:

  12. Measurement Cornell Notes Other English- SI comparisons: • 1 inch= 2.5 cm • 1 gram= mass of a paper clip • 1mL= 1/5 of a teaspoon • 1m= 1 yard + 3 inches • 2L = soft drink bottle

  13. Measurement Cornell Notes: Summary In your own words summarize what you have learned. Hint: Try to develop a short answer to our essential question (located at the top of our Cornell Notes)

  14. Measurement Scavenger Hunt Activity Turn over to the back side of your Cornell Notes Handout. • With a partner, you will suggest items in the classroom that fits each measurement listed in the table (without measuring) • Write the items that you identify in the first column to the left of the specified length. • Obtain a ruler and return to the identified items, Measure the item and write the value in the Actual length column beside the specified item. • In the column that reads inches, you will convert cm, m, mm to inches ( do as many as you can utilizing the conversions from your Cornell Notes. • In the last column, Difference, you will subtract the actual length from the length. • For example: you identified an iphone to be 22cm but after measuring you determine the length to be 17.5cm your data table would be completed as shown in the table below.

  15. Lets get started!Ask questions if needed!!!(Remember three before me)
