1. Biology

Tissues in the Body

Plant Tissues:

Meristematic tissues - Is a type of tissue system in plants composed of a mass of undifferentiated cells and their primary function is to take part in the growth of plants.

Permanent tissues- Are differentiated tissues doing specific functions such as conduction, providing mechanical support or carry out photosynthesis.

2. Physics

Objects in motion Newton’s Third Law:

Ex. The baseball forces the bat to the left (an action); the bat forces the bat forces the bat to the right (the reaction). Ex. When air rushes out of a balloon, the opposite reaction is that the balloon flies up.

Environmental Stewardship

Natural Resources: Ever since the earth was inhabited, humans and other life forms have depended on things that exist freely in nature to survive. These things include water (seas and fresh water), land, soils, rocks, forests (vegetation), animals (including fish), fossil fuels and minerals. They are called Natural Resources and are the basis of life on earth.

Conservation and Protection: Environmental conservation is an umbrella term that defines anything we do to protect our planet and conserve its natural resources so that every living thing can have an improved quality of life. Environmental conservation comes in many forms and reminds us to be mindful of daily choices. No matter how busy your life may be, it remains fairly easy to make small, yet necessary, changes for the good of the Earth. If we all took little steps, we would make our way towards major progress. This can be achieved by paying more attention to what we buy and not using resources unnecessarily. We must also remember to recycle and dispose of chemicals properly so that the ground and bodies of water are not poisoned.

4. Philosophy of Science and Teaching

History and methods of Western Science

Science in the Middle Ages: European science in the Middle Ages comprised the study of nature, mathematics and natural philosophy in medieval Europe. Following the fall of the Western Roman Empire and the decline in knowledge of Greek, Christian Western Europe was cut off from an important source of ancient learning

Science in the Modern Times: Science will always look for explanations for what goes on in the natural world and test those explanations against evidence from the natural world — but exactly how this gets done may evolve. The scientific enterprise is not static. Science is deeply interwoven with society, and as it has changed, so too has science. Here are just a few examples of how modern scientific practices have been transformed by increasing knowledge, changing societal concerns, and advances in communication and technology

Physics

Sound

Detecting Objects with Sound:

Electrostatic microphones: are frequently used for measurement since they are easily downsized, have flat frequency responses over a wide frequency range, and provide markedly high stability.
