  1. Earth Materials Investigation 1 Mock Rocks Part 1 – Investigating Mock Rocks

  2. Science Safety • Scientists follow safety procedures to protect themselves when performing observations and experiments • They wear goggles to protect their eyes • They used the tools carefully so that they do not harm themselves or others • They do not put any scientific materials in their mouths • Spills are cleaned up quickly using the correct procedure

  3. Science Jobs • Manager – this person will make sure that all members are on task • Reporter – this person will report the results of their groups work, you may need to take notes • Materials getter – this person will get materials • Materials collector – this person will return materials

  4. What We Will Learn • Rocks have many properties, including shape, size, color, and texture • Geologists use rock properties to help identify different rocks • Some dimensions of rocks can be measured and compared

  5. What We Will Do • Make and record observations of mock rocks. • Compare the properties of mock rocks with those of real rocks. • Choose appropriate measuring tools to determine the diameter, circumference, depth and mass of rock rocks.

  6. Vocabulary • ology – study of • ologist – a person who studies • ento – insects • bio – life • geo – earth • Talk in your groups and decide what the following would be: study of insects, study of life, study of earth – a person who studies insects, a person who studies life, a person who studies earth

  7. Vocabulary • earth materials – the non-living substances that make up the earth’s interior, surface or atmosphere • properties – something you can observe such as size, color, shape, or texture.

  8. How scientists study rocks • First scientists make detailed observations and record their observations. • They observe first because tests they make change the rock. • They compare their observations with the results of the tests.

  9. Rock Properties • We will observe the rocks to determine their • size – measured in centimeters • shape – round, oval, irregular • color – black, brown, tan, white, bits of color, etc. • texture – smooth, bumpy, sharp edged

  10. Vocabulary • Diameter – the distance across a circular object at its widest point • Circumference – the distance around a circular object

  11. Earth Materials Mock Rocks – Page 3 • Depth – how thick an object is from top to bottom, thickness • Meter tape – measures objects in centimeters, a tape can measure odd shaped objects; a meter stick can only measure length

  12. Materials • Material Getters will get the trays with • 4 paper plates • 4 mock rocks • 4 hand lenses • 1 meter tape • You will record your information in your Earth Materials Booklet. • Your work in your Earth Materials Booklet will be graded, so do your best work.

  13. Earth Materials Booklet Mock Rocks – Page 2 • Talk in your group and discuss the properties of your mock rocks • Help each other make sure you record all of the properties • Reporters share some of your groups observations of properties

  14. Earth Materials Booklet Mock Rocks – Page 2 • Observe your mock rock carefully – this is a simulation of a real rock. • Draw or trace your mock rock in your booklet. • Use the hand lens to magnify your rock. • Write down your observations. • The challenge is to describe your rock in detail so that later if your rock changes in any way you can identify the changes.

  15. Earth Materials Booklet Mock Rocks – Page 3 • Use the meter tape to record the measurements of your rock. • Measure across the widest part of your rock for the diameter • Measure around your rock for the circumference • Measure from the top to the bottom of your rock for its depth. You will have to get down and look from the side to determine the depth

  16. Earth Materials Booklet Mock Rocks – Page 3 • Take in your group and compare the measurements of your mock rocks • How close are your measurements? • How different are your measurements? • Reporters – share some of your groups findings.

  17. Review • What are some of the tools scientists use to study rocks? • hand lenses, meter tapes • What information does each tool provide? • hand lenses can help you determine properties such as color and shape • meter tapes can help you determine the diameter, circumference and depth

  18. Review • What kind of information is important to include in notes? • properties – size, shape, color, measurements • any information that will help you identify the object • How is a mock rock like/different from a real rock • it is alike because it is made up of different materials • It is different because

  19. Review • How would you study a real rock? • You would study a real rock the same way we studied the mock rock

  20. What We Learned • Rocks have many properties, including shape, size, color, and texture • Geologists use rock properties to help identify different rocks • Some dimensions of rocks can be measured and compared

  21. Written in Stone • Read this story. Students will need to share books.
