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:

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.
