Quiz Topics
1.1 Introduction to Chemistry and Laboratory Skills
Specific Competence: Understand chemistry, its importance, and how to work safely and accurately in a lab. Learning Activities: Students will learn what chemistry is and its main areas. They will find out why chemistry is important in daily life, like in food or medicine. They will learn how to stay safe in the lab, including using equipment and handling waste correctly. They will practice measuring things accurately. Expected Standard: Students will show they understand chemistry and its importance. They will correctly follow lab safety rules, manage waste, use lab tools, and measure accurately.
1.2 Matter and its States
Specific Competence: Understand matter, its different forms (states), and how it behaves when heated or cooled. Learning Activities: Students will explore the forms of matter: solids, liquids, gases, and plasma. They will learn about the tiny particles that make up matter, like atoms and molecules. They will understand how these particles move (kinetic theory of matter) and how this explains changes like diffusion (spreading out). They will also learn to draw and understand graphs that show how matter changes when heated or cooled. Expected Standard: Students will show they understand matter, how its particles move, and how to work with heating and cooling graphs.
1.3 Elements, Compounds, Mixtures, and Separation
Specific Competence: Understand elements, compounds, and mixtures. Tell the difference between physical and chemical changes. Test how pure a substance is and separate mixtures. Learning Activities: Students will describe elements (basic substances), compounds (substances made from two or more elements joined together), and mixtures (substances physically combined) and show how they are different. They will learn about changes that substances go through, whether they are physical (like melting ice) or chemical (like burning wood). They will learn how to check if a substance is pure and why this is important. Students will also practice different ways to separate mixtures, such as filtering (removing solids from liquids) or distilling (separating liquids by boiling and condensing). Expected Standard: Students will show they understand elements, compounds, and mixtures. They will correctly tell the difference between physical and chemical changes. They will be able to check for purity and separate mixtures correctly.
1.4 Atomic Structure
Specific Competence: Understand what an atom is and its parts. Know the properties of these tiny parts. Calculate the number of these parts in an atom. Learning Activities: Students will learn about different models of the atom. They will identify the tiny parts inside an atom: protons (positive charge), neutrons (no charge), and electrons (negative charge). They will learn about the charge and weight of each part and why an atom is usually neutral (has no overall charge). They will also learn about atomic number (number of protons) and mass number (total protons and neutrons), and how to use them to find the number of protons, neutrons, and electrons. Expected Standard: Students will show they understand atomic structure and the properties of its parts. They will correctly calculate the number of subatomic particles.
1.5 Atomic Structure Applications and Isotopes
Specific Competence: Interpret chemical symbols. Show how electrons are arranged in an atom. Calculate the average mass of an element. Handle radioactive forms of elements safely. Learning Activities: Students will learn to read and write chemical symbols (e.g., H for hydrogen) and special notations for atoms (nuclide notation). They will understand how electrons are arranged in shells (energy levels) around the atom's nucleus (electronic configuration) and how this relates to the Periodic Table. They will learn about isotopes (atoms of the same element with different numbers of neutrons) and how to calculate an element's average atomic mass (relative atomic mass). Students will also explore how radioactive isotopes (radioisotopes) are used in areas like medicine and energy, and learn how to handle them safely due to their health risks. Expected Standard: Students will correctly read chemical symbols and notations. They will correctly apply electron arrangements. They will correctly calculate relative atomic mass. They will show how to manage radioisotopes safely.
