Mrs. Kahler's 8th Grade Science Class

Friday, December 14, 2007


One week left before Winter Break begins. Hip-Hip-Hooray! We are all in need of a break. Can you believe that we haven't had a snow day so far this year? Wow! I'm not sure if that is good or bad.


Thank you for all the nonperishable food items that you sent in to Advisory. Milwood had a nice amount brought in to help the local food banks.


Have a wonderful break!

Schedule:

Science

Please note that as of Sunday afternoon, each day's lesson will be moved back one. Students need Monday to go over their last assessment and make some corrections. Your child will receive their test back on Monday and should make any changes according to the test reflection and return on Tuesday.

Progress Reports will be printed on Wednesday and sent in the mail no later than Friday.

Test reflection and Correction Paper:

Test%20Reflection%20AND%20Corrections.doc




Monday, December 17th

Students will finish the lab from Friday on "Making Waves" p. 502-503.

Benchmark: P1.1h Design and conduct a systematic scientific investigation that tests a hypothesis. Draw conclusions from data presented in charts or tables.

Tuesday, December 18th

We will be viewing a short video titled, "Elements of Physics: Waves: Sound and Electromagnetism". Before the video, we will start with a short Pretest. During the video, we will gather information on the information and then after the video, we will take a short quiz on it.
Benchmark: P4.4B Identify everyday examples of transverse and compression waves.


P4.5A Identify everyday examples of energy transfer by waves and their sources.


P4.5B Explain why an object does not move forward as a wave passes under it.


P4.5C Provide evidence to support the claim that sound is energy transferred by a wave, not energy transferred by particles.

Wednesday, December 19th

Students will view a PowerPoint on Electromagnetic Waves. They will put some notes in their Science Journal.

Homework: Electromagnet Radiation

P4.6A Identify the different regions on the electromagnetic spectrum and compare them in terms of wavelength, frequency, and energy.

Thursday, December 20th
Students will view a PowerPoint on Reflection and Refraction that contains short video clips in it and put important notes in their journal.

P4.8A Draw ray diagrams to indicate how light reflects off objects or refracts into transparent media.


P4.8B Predict the path of reflected light from flat, curved, or rough surfaces.


P4.9A Identify the principle involved when you see a transparent object in a clear liquid.


P4.9B Explain how various materials reflect, absorb, or transmit light in different ways.

Friday, December 21st

Students will complete a lab, "Make a Light Bender".

P4.9A Identify the principle involved when you see a transparent object in a clear liquid.


Global Warming

Monday, December 17th

Finish video from Friday, December 14th.





Wednesday, December 19th

Students will complete a lab on " Modeling the Greenhouse Effect". They will construct a physical model of the atmosphere and discover that air trapped in a container will heat up more than air in an open container.


P1.1A Generate new questions that can be investigated in the laboratory or field.


P1.1.C Conduct scientific investigations using appropriate tools and techniques.


P1.1D Identify patterns in data and relate them to theoretical models.


P1.1.E Describe a reason for a given conclusion using evidence from and investigation.





Friday, December 21st


Finish Wednesday's lesson.

Well, this is Mr. Korchnak's last week with us. He has been so helpful to the students, families and to me. We are really going to miss him. He will be moving to NY with his wife after Christmas and substitute teaching in Albany, NY. We know that he will do well, but still wish him the best of luck.

I do apologize for anyone using my blog last week. I tried to complete my blog from home and the blog was a mess. So I made sure to also post on the board in my classroom the important dates for the next week. Students know that their science assessment is moved to this Monday instead of last week.

On Wednesday, all eighth graders at Milwood will be taking the Explore test. It is a test for students and their families to see how they are progressing. It is similar to an ACT test, but for 8th graders so they can see where they would score on the ACT. This will not affect their grade, but give them a preview of what a nationally normed test would be like.

We are still collect food for our drive. Our advisory group is running a little behind in cans so donate what you can. The top three classes will receive a pizza party. That sure would be nice.

Here's our schedule:

Science

Monday, December 10th

Students will take the unit assessment on Chapters 4, 5, and 6. Bring a book for when you finish. If your class did not get a visit from Mr. Campbell, he should be coming in to talk with you about the Explore test, Recovery, and Tardies. If this takes too much of our assessment time, you will have some time on Tuesday to finish.

Bring your science journal to help you on the assessment and turn in today to receive your grade for it.

Tuesday, December 11th

Students will create flashcards for this units' vocabulary. We are going to begin to study Waves. Here is the list of vocabulary for the unit:
wave,pitch,medium, intensity
transverse wave, loudness
crest, ultrasound technology
trough, music
wavelength, noise
amplitude, resonance
frequency, quality
compressional, wave interference
reverberation, acoustics

These flashcards will be due on Thursday, December 13th.


Wednesday, December 12th

No science class since students will be taking the Explore test.

Thursday, December 13th

Teacher will check your vocabulary flash cards. We will view a PowerPoint on the characteristics of waves (Physical Science ch. 18.1 page 498). Students will put the notes they take into their journal. Students will have guided practice on how to calculate the velocity of a wave and how to calculate the frequency of a wave. They will then have a worksheet to complete at home and to return tomorrow for a grade.

Friday, December 14th

Collect and correct the homework from last night. Students will write and complete their own experiment concerning which wave quantities they can influence when making transverse waves in a spiral spring. They will also see what happens when this spiral spring hits an immovable barrier. Students will turn in their lab sheets at the end of the period.

Global Warming

Tuesday, December 11th

Students will get their Global Warming folders back today. They will complete a class building activity using Inside-Outside Circles. Then we will go back to our seats and watch: Biomes: The Threat of the Sea. This will help us in our research on Global Warming and the Greenhouse Effect.

Thursday, December 13th

We will sit in teams and complete a team line-up activity. Students in their teams will line up by finding where they stand relative to their teammates on some questions on the greenhouse effect and global warming. Students will then finish the rest of their video from Tuesday. Global Warming folders will be collected and graded.
