- Leaf Structure & Function: label a leaf diagram and explain the structures' functions.
- Transpiration: describe how atmospheric humidity levels affect transpiration.
Chemistry Chapter 4
- Valence Electrons, Ions, Metals/Non-metals: identify valence electrons, cations, anions, metals, and non-metals in the periodic table.
- Element Names/Symbols: identify names and symbols of elements.
- Bonding Types: define and identify ionic and covalent bonding types.
- Compound Names/Formulas: write names and formulas for diatomic molecules, binary ionic compounds, ionic compounds with polyatomic ions, and binary molecular compounds.
- Chemical Equations: write chemical equations (word, skeleton, and balanced).
Chapter 5
- Chemical Reactions: identify different types of chemical reactions (synthesis, decomposition, single displacement, double displacement, neutralization, combustion).
- Evidence of Chemical Change: recognize and identify evidence of chemical changes.
Chapter 6
- Acid-Base Properties: know properties of acids and bases.
- Acid/Base Formulas: write formulas for binary acids, oxoacids, and bases.
- pH Scale: describe the pH scale and recognise and apply the log nature of it.
- Neutralization Reactions: write balanced chemical equations for neutralization reactions.
Chapter 10 Optics
- Light Travel: light travels in straight lines; objects reflect light to be visible.
- Mirrors: identify various mirror types, their applications, and image characteristics (concave and convex mirrors).
- Characteristics of Images: understand the meaning of virtual images and image characteristics.
Chapter 11
- Refraction Definition: define refraction of light as a change in speed when light enters a new medium.
- Refraction Diagram: label a refraction diagram with understanding of partial reflection.
- Index of Refraction: define index of refraction and its indication of light behavior changes (how light will behave).
- Light Bending/Reflection: relate light bending toward or away from the normal with angle of incidence.
- Partial Reflection/Refraction: describe the relationship between partial reflection and refraction at different angles.
- Speed of Light: solve problems using the formula n=c/v.
- Total Internal Reflection and Critical Angle: Understand total internal reflection, explain critical angle as the angle of incidence when light travels from a more dense medium to a less dense medium.
- Total Internal Reflection Applications: discuss applications of total internal reflection.
Chapter 12
- Lens Types: Identify converging (convex) and diverging (concave) lenses.
- Light Path through Lenses: sketch the path of light through convex and concave lenses.
- Image Characteristics: describe image characteristics for both lens types (real, virtual, inverted, upright, etc.).
- Lens Image Types: Recognize that concave lenses only produce virtual images, while convex lenses produce both real and virtual images, depending on object position.
- Convex Lens Image Formation: convex lenses produce virtual, upright, larger images when the object is close to the lens; real, inverted images when further away.
- Ray Diagrams: draw ray diagrams for convex and concave lenses, labelling parts (focal point, principal axis, etc.).
- Locator Rays: describe how 3 locator rays (parallel, central, and focal) behave when passing through lenses, and their use in locating and describing images.
- Image Location/Description: use locator rays to locate and describe images.
- Numerical Calculations: solve problems using lens formulae.
- Exam Preparation: guidelines for exam preparation (materials, format).
