Study Notes
Grade 10 Biology
- Cells are the fundamental units of life, containing organelles with specific functions. All living organisms are composed of cells.
- Cell structure includes organelles like the nucleus, mitochondria, and chloroplasts, each with specific roles in cellular processes.
- Cells carry out various processes like respiration, photosynthesis, and protein synthesis to maintain life.
- Genetics is the study of inheritance of traits from parents to offspring. DNA carries genetic information.
- Ecosystems are interconnected systems of living and non-living components. Food chains and webs demonstrate these relationships.
- Human Biology examines human body systems (e.g., digestive, respiratory, circulatory), focusing on organ functions and interactions and understanding health and disease.
- Evolution is the process of change in species over time due to natural selection, which results in adaptation to environments.
Grade 10 Chemistry
- Matter is composed of atoms and molecules. Properties of matter (physical and chemical) are characteristics of these.
- Atoms are composed of protons, neutrons, and electrons. Elements are organized by properties on the periodic table.
- Chemical bonding involves forces holding atoms together in compounds, including ionic, covalent, and metallic bonds.
- Acids donate hydrogen ions (H+), and bases accept hydrogen ions; the pH scale measures acidity/basicity.
- Chemical reactions involve the rearrangement of atoms to form new substances. Types of reactions include synthesis, decomposition, and combustion. Solutions are homogeneous mixtures of two or more substances; concentration influences this. Stoichiometry relates quantities in reactions.
- Organic chemistry focuses on carbon-containing compounds, crucial for life processes, including carbohydrates, lipids, proteins, and nucleic acids.
Grade 10 Climate Change
- The greenhouse effect is a natural process where atmospheric gases trap heat.
- The enhanced greenhouse effect is caused by increased greenhouse gases (GHGs) due to human activities, resulting in global warming. Fossil fuel burning is the primary cause.
- Rising global temperatures cause changes in weather patterns, including increased frequency/intensity of extreme weather events like heatwaves, droughts, floods, and storms. Glacial melt is also a concern.
- Climate change impacts include damage to ecosystems, displacement of populations, changes in agricultural yields, and impacts on human health.
- Mitigation strategies involve reducing GHG emissions through renewable energy, efficiency improvements, and sustainable land use. Adaptation strategies adjust to effects with infrastructure improvements, water management, and developing drought-resistant crops.
Grade 10 Optics
- Light is an electromagnetic wave, traveling at a constant speed. Light reflects off surfaces (angle of incidence equals angle of reflection).
- Light bends when passing between mediums (refraction).
- Mirrors (plane, concave, and convex) reflect light to create images (real and virtual).
- Lenses (converging [convex] and diverging [concave]) use refraction to focus light.
- Optical instruments (microscopes, telescopes, cameras) use reflection and refraction principles.
- Refractive index quantifies bending.
- The electromagnetic spectrum includes visible light, which is a small part of a broader range from radio waves to gamma rays. Light is a transverse wave with characteristics like wavelength, frequency, and speed.
