Grade 8 Cambridge Checkpoint Science – Summary Lesson Plan Subject: Science Topic: Forces and Types of Forces Level: Grade 8 (Checkpoint) Duration: 60 minutes Lesson Objectives: By the end of this lesson, learners should be able to: * Define what a force is. * Identify and describe different types of forces. * Understand how forces affect motion. * Differentiate between contact and non-contact forces. * Apply knowledge of forces to real-world situations. Lesson Breakdown: Introduction (10 minutes) * Begin with a brief discussion: “What is a force?” * Display a few real-life examples (e.g., pushing a door, magnets attracting objects). * Define force as a push or pull upon an object resulting from its interaction with another object. * Introduce units of force: measured in Newtons (N) using a spring balance. Main Content (30 minutes) 1. Effects of Forces (5 mins) * A force can: * Start motion * Stop motion * Change the speed * Change the direction * Change the shape of an object 2. Types of Forces (25 mins) A.Contact Forces: * Occur when objects are physically touching. * Examples: Friction: A force that opposes motion between two surfaces. Air resistance: A type of friction acting on objects moving through air. Tension: Force transmitted through a rope, string, or cable. Normal force: The support force exerted upon an object in contact with another stable object. Applied Force: A force applied to an object by a person or another object. B. Non-contact Forces: * Act at a distance without physical contact. * Examples: Gravitational force: Attraction between two objects with mass (e.g., Earth and objects). Magnetic force: Force between magnetic poles. Electrostatic force: Force between charged particles. Class Activity (10 minutes) * Demonstration: Use a magnet and paperclips, or rub a balloon on hair to show static electricity. * Think-Pair-Share: Students list as many forces as they can find in their classroom environment. * Discuss their examples and categorize them as contact or non-contact forces. Conclusion (5 minutes) * Summarize key points: A force is a push or pull. Forces can cause changes in motion, shape, or state. Forces are either contact or non-contact. Understanding forces helps us explain many everyday phenomena. Exercise (5 minutes) Answer the following questions in your notebooks: 1. What is the unit of force and which instrument is used to measure it? 2. Name two contact forces and two non-contact forces. 3. Explain how friction can be both helpful and a hindrance in daily life. 4. A book is resting on a table. Identify and describe the forces acting on the book. 5. Differentiate between gravitational and magnetic force with examples.

Protein Synthesis – Edexcel A-Level Biology (Brief Class Summary) 1. Overview Time: 10minutes Protein synthesis is the process by which cells build proteins based on genetic instructions. It occurs in two main stages: transcription and translation. 2. Key Stages Time: 40 minutes a) Transcription (Nucleus) - DNA unzips and RNA polymerase reads the template strand. - mRNA (messenger RNA) is synthesized using complementary base pairing. - mRNA leaves the nucleus via nuclear pores. b) Translation (Ribosome – Cytoplasm) - Ribosomes read the mRNA codons. - tRNA brings specific amino acids to the ribosome. - Anticodons on tRNA match with codons on mRNA. - Amino acids link via peptide bonds, forming a polypeptide. 3. Important Molecules - DNA– Stores genetic code. - mRNA – Temporary copy of gene. -tRNA– Transfers amino acids. -Ribosomes – Site of protein synthesis. -Amino Acids– Building blocks of proteins. 4. Conclusion Time: 10 Minutes - Understand codon-anticodon matching. - Be able to describe transcription and translation step-by-step. - Practice interpreting DNA → mRNA → amino acid sequences.
