Discuss sound and light as waves. Review how sound requires a medium while light does not. Define vibration and wave. Explain period of a wave. Demonstrate the production of a simple harmonic motion wave, a sine wave. Form a sketch of the wave label and define the crests, trough , wave length, and amplitude. Define frequency of the wave and discuss units. Define wave period and relate it to the frequency.

Kellan used iron filings and a bar magnet to see the magnetic field around a bar magnet. He read about electrical energy and electrical current. He summarized the text and we discussed examples. I showed him a copper wire and discussed electric current. He watched a video about electricity.

Kellan was absent today. I took the period to lesson plan.

Bella watched a crash course video and completed comprehension questions. After the video, we reviewed her answers. I emailed the word doc Bella completed to Nicole for review.

Dane took a quiz on atomic theory. We then introduced the next unit on the water cycle by watching a Magic School Bus episode.

We discussed the conservation of mass during physical and chemical changes.

Questionnaire of 130 questions answered online. 7 questions answered in paragraph form following the 130 questions. This took the form of an analysis of the 130 question questionnaire.

In today's lesson Sofia and I continued going over how climate and weather is influenced by multiple factors. First we reviewed how latitude affects climate and geographical location influences weather. We then started to discuss how altitude and geography can influence weather and climate.

Discussion regarding viral infection, and why it is so difficult to treat medicinally, due to the host cell being involved in the reproductive cycle of the virus... Types of treatment involve systemic agents which interfere with DNA synthesis, agents which prevent entrance of the virus into the host cell, and agents which inhibit specific enzyme found on viral surfaces... Transcription and translation were explained and the drugs used to interfere with the transcription or translation of the viral RNA introduced.

Classification of viral infections by duration, severity and extent of infection... Duration includes acute, chronic and slow infections,with definitions and examples of each. The extent of infection includes localized or general, followed by definition and examples of each. The principle of latency was discussed in terms of herpes and hiv virus infections.
