The following topics will be covered this year in Earth Science.
The sun is the major source of energy for phenomena on the surface of the Earth.
Human activities have changed the land, oceans and atmosphere of the Earth resulting in the
reduction of the number and variety of wild plants and animals sometimes causing extinction of species.
Weather and Climate-
Global patterns of atmospheric and oceanic movement influence weather and climate.
The following topics will be covered this year in life science.
Cell Functions –
All organisms are composed of cells, from one cell to many cells. Inn multi-cellular organisms, specialized cells perform specialized functions. Organs and organ systems are composed of cells and function to serve the need of cells for food, air, and waste removal. The way in which cells function is similar in all living organisms.
Growth and Development-
Following fertilization, cell division produces a small cluster of cells that then differentiate by appearance and function to form the basic tissue of an embryo.
Plants are producers; they use the energy from light to make sugar molecules from the atoms of carbon dioxide and water. Plants use these sugars along with minerals from the soil to form fats, proteins, and carbohydrates. These products can be used immediately, incorporated into the cells of a plant as the plant grows, or stored for later use.
Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. Some organisms reproduce asexually. Other organisms reproduce sexually.
The following topics will be covered in physical science this year.
Matter has chemical properties. The understanding of chemical properties helps to explain how new substances are formed.
Elements and Compounds-
Elements are composed of a single kind of atom that are grouped into families with similar properties on the periodic table. Compounds are composed of two or more different elements. Each element and compound has a unique set of physical and chemical properties such as boiling point, density, color, conductivity, and reactivity.
Chemical changes occur when two elements and/or compounds react and produce new substances. These new substances have different physical and chemical properties than the original elements and/or compounds. During the chemical change, the number and kind of atoms in the reactants are the same as the number and kind of atoms in the products. Mass is conserved during chemical changes. The mass of the reactants is the same as the mass of the products.
