Science Classroom Connection

I hope that your summer has been a restful and enjoyable one, as we embark on our eighth grade journey to learn and explore new concepts and ideas in the coming months. Meanwhile, if you are planning to come prepared on the first of the school year, here is the suggested list for school supplies for 8th graders that covers ALL of your classes:

• 2 Boxes of tissues
• 3 Containers of disinfectant wipes
• 1 Bottle of hand sanitizer
• Good Supply of #2 Pencils
• Erasers
• Small Stapler
• White out
• Red pens (a pack of 5)
• Colored Pencils (24)
• Markers
• Black pens
• Highlighters
• Wide ruled paper
• 6-9 single subject spiral notebooks
• Rulers-all graphs much be drawn with a straight edge
• Crayola Dry Erase Markers/eraser
• Glue sticks
• Scissors
• 2 pocket folders with prongs, one for each class (Math, Science, Language Arts, Reading, and Social Studies)
• Math class: One HEAVY DUTY OR ULTRA DUTY, 1 1/2″ to 2”,  three-ring binder with window pane for cover sheet
• At least 8 divider tabs for binders
• Calculator- TI – 30X II S or  Ti 84 or other graphing calculator.  An investment into a good calculator can go a long way!
• Zippered Pencil pouch
• For Computer Class:  Auto or lead pencils, a plain folder with prongs and pockets,  A good set of headphones or earbuds and an 8GB (or higher) Thumb Drive

Study Guide

Here is a set of questions that will help you to prepare for our upcoming final exam.

1. Identify and label parts of a wave.
2. Identify a wave on an oscilloscope based on the wave’s frequency, pitch, and amplitude in terms of its loudness/softness.
3. Explain how sound and light waves are able to travel through different mediums.
4. Review the electromagnetic spectrum in terms of its characteristics based on frequency, wavelength, energy, and color characteristics on the spectrum.
5. Distinguish among the terms transparent, translucent, and opaque.
6. Describe how light behaves as it enters the 2 different lenses.
7. Describe how do you remember the colors of the visible light on the EM spectrum.
8. Compare a mold to a cast when studying fossils.
9. Define: index fossil, trace fossil, amber, superposition, carbon-14 and Uranium-Lead dating methods, disconformity, nonconformity, and angular unconformity.
10. Compare and contrast relative dating with absolute dating.
11. Distinguish between radioactive decay and radiometric dating.
12. As you think of a geologic column, be able to identify or tell the difference among tilting, folding, angular unconformity, intrusion, and a fault.
13. Review the rock layer diagrams that was given to you and be able to label the rock layers from oldest to youngest and vice versa.
14. Be able to distinguish between James Hutton’s and Charles Lyell’s literature work as well as the ideas of uniformitarianism and catastrophism.
15. Half-life problems: If you have practiced on the “Extra-problems Worksheet” that was given to you, then you will EASILY be able to solve the similar problems on the test.

A small group of so-called scientists have attempted to put together a geological column that is based on similar rock layers with same fossils (different shapes) embedded in them. Click on and view the attachment below!

Geological Column 2

Geological Column 1

Students make sure that you have completed the following 2 foldables by Thursday that are based on the concepts that we have learned and discussed in Section 3.2: Relative Dating.

Definition Foldable #1

Chapter 3 Section 2

Relative Dating

Superposition

Geologic Column

Unconformity

Angular Unconformities

Fault      

Intrusion

Disconformities

Vocab Foldable #2

Chapter 3 Section 2

Using a half-sheet of printer paper, sketch a picture on each of the following 4 concepts on the outside flap. Then on the inside of the same flap write the term or concept on one side and adjacent to it have the explanation of it.

Disturbed Rock Layers Foldable (Page 66)

Fault

Folding

Intrusion

Tilting

Students: Make sure that you have completed your homework assignment on Section 3.2: Relative Dating: Which Came First? Tomorrow, it will be corrected and graded by your classmates. Since it is Ramadan, honesty will be easy to reinforce, as we did today!

Remember that the textbook was shared with you through your school email that you received from the classroom teacher on Saturday, May 11, 2019.

Here is the list of vocabulary terms if you did not finish in class:

James Hutton

Charles Lyell

Paleobotanist

Paleontology

Uniformitarianism

Catastrophism

Vertebrate Paleontologist

Invertebrate Paleontologist

*Gradualism

*Punctuated Equilibrium

Gradualism: The hypothesis that evolution proceeds mainly by the accumulation of gradual changes over time.

Punctuated Equilibrium: The hypothesis that evolutionary development is marked by isolated episodes of rapid speciation (the formation of new and distinct species in the course of evolution) between long periods of little or no change.

Congratulations to many of you who have done a good job on this summative evaluation.

There were 39 A’s and 23 B’s and several C’s.

Keep up the good work, as we enter the final stretch home with Chapter 3: The Rock and the Fossil Record.
