students should be able to:
-demonstrate how heat energy flows from warmer objects to cooler objects
-draw conclusions from an experiment

The do now was a quiz on waves.

Students reviewed the answers to HL 8 and 9.

Notebooks were distributed.

Students spent the remainder of the period completing Lab 10: Heat Energy Transfer. For those students who were absent, please print out the pages at the top of this blog and complete the activity at home. Papers must be submitted on Monday, 5 January.

Please remember that the science interim exam AND mid-term exams will be held the first week we return from winter break. Study all information from the beginning of the school term up through force and motion.

Merry Christmas and a Happy New Year!

This is HL #8. Answer using blue/black ink or pencil. Head a sheet of loose leaf paper correctly. Be sure to include the title of this home learning on the first line. Answers only (A, B, or C)


This is HL #9. Answer using blue/black ink or pencil. Head a sheet of loose leaf paper correctly. Be sure to include the title of this home learning on the first line. Answers only (is, is not)



These are the handouts to use to record your data for Lab 9. Be sure to write all data in pencil. Use blue or black ink for the remainder of the sheet.


Using information from virtual labs, internet access, and classroom discussions,
students should be able to:
-use an oscilloscope to tune a trombone by matching the waveforms.
-calculate the frequency of a pitch when given wavelength and velocity.

The do now consisted of FCAT type questions, that can be found below.


Students received HL 8 and HL 9, which can be found at the top of this blog. They are to be done on separate, loose leaf pages, headed correctly, written in either pencil or blue/black ink. Remember to put the title of the assignment on the first line.

Students spent the remainder of the period performing the online lab on sound. Absent students can turn in the lab tomorrow. Print out the handouts, go to Dr. Gayden's Science Zone (drgcdms.podomatic.com), use the link posted under Wednesday, 17 December, 2008. Remember to use pencil to do all data. The handouts are also listed above.

Notebooks were collected and will be returned tomorrow.

Using information from laboratory experiments and classroom discussions,
students should be able to:
-calculate percent reflectivity of various colors.
-draw conclusions using the results of an experiment.

The do now was FCAT practice. Try to find the answers to the following:



Students turned in HL 6 and 7 and reviewed the answers.

Students then calculated the percent reflectivity for each of the papers used. They found the means for the class for each type of paper and then compared their group values to those of the class's mean.

We then finished the conclusions and analysis for lab 8 on the reflectivity of light.

Students should teach their parents/guardians from the topics energy, heat, waves, sound waves or light waves. Be sure to have the adult write what they have learned in the adult input space in the notebook. Also, be sure all notes are updates: 3 Costa's levels of quality questions, one from each level; color coordination of questions to answers in the notes; summary of the notes; all handouts, do-nows, and home work papers should be pasted in the notebook on the appropriate days.

This is HL #7. Use blue/black ink, or pencil. Write on loose leaf paper, properly headed. Answers (letters) only.

Using information from laboratory experiments, Venier probe technology, and classroom discussions,
students should be able to:
-use a light sensor to measure reflected light.
-calculate percent reflectivity of various colors.
-draw conclusions using the results of an experiment.

The do now was an FCAT practice question:


Students received HL #6 and HL #7. Both are due tomorrow. Use separate paper to write each assignment. They can both be found at the top of this blog.

Students spent the remainder of the period working on the lab: reflectivity of light. Absent students should visit Dr. Gayden's Science Zone (http://drgcdms.podomatic.com) for make-up assignments.

Monday, 15 December, 2008

Using information from internet access, videos from the internet, and classroom discussions,
students should be able to:
-compare and contrast reflection and refraction.
-define diffraction.

The do now was an FCAT practice question:
Which wave has the greatest frequency?
Wave Name-----Number of Waves----Time elapsed (in seconds)
Wave A---------------12------------------40
Wave B---------------- 6 -----------------60
Wave C----------------20 --------------- 240
Wave D----------------10-----------------15

Students viewed BrainPop movies on light and refraction vs diffraction. They spent the remainder of the time in individual study on light. The links for the learning site are found at Dr. Gayden's Science Zone (drgcdms.podomatic.com). Be sure to write the definitions for reflection, refraction, and scattering in your notes. Also, draw the diagrams for reflection and refraction.

Friday, 12 December, 2008

Using information from internet access, virtual activities, and classroom discussions,
students should be able to:
-describe how sound waves travel through matter.
-describe how sound waves are produced.
-describe the relationship between loudness and sound intensity.

Welcome back, 7th graders! This site will be updated daily to inform you of work done in the classroom. Don't forget to check Dr. Gayden's Science Zone for additional information to help you complete the tasks!

The do now was an FCAT question, which was copies and answered:
When an earthquake causes the seafloor to push upward, a tsunami can occur. Tsunamis are dangerous ocean waves that can reach great heights just before they strike a beach. What property of a tsunami makes it dangerous to people on the beach?
A. amplitude
B. frequency
C. trough
D. wavelength

After completing the do now, students did independent learning by visiting the Dr. Gayden's Science Zone site to find links for studying sound energy and sound waves. (drgcdms.podomatic.com) You must scroll down to November 17 to find the links for these activities.

Wednesday, 3 December through Friday, 5 December, 2008

Using information from videos, students should be able to:
-state the modes of transmission of HIV
-describe practices that prevent the spread of HIV
-participate in discussions on HIV/AIDS.

The do now on Wednesday was to read the procedures for the lab.
The do now on Thursday was a quiz on speed, acceleration and velocity.
The do now on Friday was a quick write: What is your greatest fear about HIV/AIDS?

On Wednesday, we completed the lab on force and work as a function of size. Students missing the lab should visit Dr. Gayden's Science Zone (drgcdms.podomatic.com) and print out the lab sheets, then use them to do the listed activity. Turn in the sheets for the next class meeting.

On Thursday, we watched the BrainPop movie on AIDS. Right now, it is free. Visit www.brainpop.com, type in AIDS in the search box, and watch the movie once it loads.

We spent the rest of Thursday doing an activity that demonstrates how the virus can spread, even to people not having contact with the original carrier.

Thursday's home learning can be found at the top of this blog.

Friday's lesson was a continued discussion on HIV/AIDS. Students watched video presentations on the topic and discussed opinions, beliefs, and fears concerning AIDS and HIV infection.

All science fair projects are now past due. Bring in a late project Monday, but be aware you will loose a small percentage of points for lateness.

Monday, 1 December and Tuesday, 2 December, 2008

Using information from laboratory experiments, students should be able to:

-analyze data and draw conclusions from an experiment.
-calculate acceleration, force, and work based on experimental data.

Students did the lab Collision Course. Absent students should visit the Dr. Gayden's Science Zone to find a make-up lab. Print out and use the lab sheet to do the lab.
