Hi. I teach living environment. However I have found many physics applications online. Energy is in most systems. I think the best use of this as a non physics teacher is by teaching circuits. Generate a regular single circuit to light a light bulb. The amount of energy entering the system is the battery. Then add a resistor or a conductor and measure the electricity at various points usin...

Oh, forgot, use compost... that can be your fertilizer. Used coffee grounds contain nitrogen, and banana peels contain potassium.

Hi. Lack of soil since soil provides most of the nutrients that aren’t in water. To make it more valid, use distilled water that will reduce the liklihood of nitrogen, magnesium, phosphates and potassium. Also consider using fertilizer which contains nitrogen, phosphorus and potassium. You can also change pH... ex: use tea, soap and that juice. Most juices are acidic - the citrus ones are a...

Valuable resource for Nutrition guidelines

The information found in this scipack is invaluable. Also included are a variety of hands on activities, and animations which help to support the information. However, I found that in some of the animations the text boxes were too small so although information was provided it could not be accessed. Also during the assessments some questions where the participant is requested to 'check all that apply' had choices which were poorly worded or extremely general which caused confusion. When the final exam was complete, I could not access the correct answers to the questions deemed incorrect without having to research the topic. Please note that although the final results lists questions as being incorrect, partial credit is given for questions where multiple answers are required. Overall the Scipack has wonderful information and activities. It is worth the time. Just be sure to take good notes and read carefully during the assessment.

History of Astrological discoveries are excellent

Excellent overview of the various scientists which established the heliocentric model and of today's current technologies. I reduced my rating by one star due to the explanation of retrograde motion, which is introduced but requires another example to expand on the interactive already provided.
