This action-packed lesson introduces current as a flow of electrons and explains the relationship between current, voltage and resistance using the analogy of a diver using up energy obtained from food and giving off heat as they swim through pipes filled either with water (low resistance) or water and rocks (high resistance). The food as a source of energy is then replaced by the battery, the diver by the electron and the rocks by metal ions. Both scenarios are animated in the PowerPoint. This explanation is then extended to compare the resistance of long, short, thick and thin wires. The practical explores the conditions needed for current to flow in a circuit. Objective To know that current is a flow of electrons through a conductor when they are given energy or pushed by a voltage from the battery. To know and explain how metal ions cause resistance. To know and explain the comparative resistance of wires according to length and thickness. To explain why electrons lose more heat passing through a high resistance conductor. To know the conditions needed for current to flow in a circuit.

This action-packed, differentiated, lesson on the structure of plant and animal cells is fully resourced with 12 activities and 14 learning outcomes. Pupils learn to label and know the functions of the nucleus, cell membrane, cytoplasm, mitochondria, cell wall, chloroplasts and vacuole. It explains that differences between plant and animal cells stem from the lack of a skeleton in plant so that the cells must provide support and that plants, anchored into the ground and unable to move to hunt, must make their own food. Easy to follow instructions are given on PowerPoint and worksheets so that the lesson practically runs itself. Activities include literacy, group work, peer assessment, self-assessment, pupil response to assessment and feedback to teacher on pupil learning via an exit ticket quiz. This pack contains material for two hours lesson time in total to enable the teacher to select resources to totally bespoke their lesson according to pupil ability, time available for the topic and focus of departmental/school policy. Any unused resources can be utilized as additional homework or pre-examination revision. An easy to follow one-page flow chart lesson plan indicates where logical choices between resources can be made and indicates whether each activity includes literacy, oracy or AFL . Objective To know why plant and animal cells are different. To be able to label the parts of plant and animal cells To know the function of the parts of plant and animal cells.

This is an engaging and enjoyable memory game on atoms, molecules, elements and compounds. Pupils work in teams of three or four. Each team lays out their 42 cards face down in a square and take it in turn to turn over two cards. If the cards are a question and its correct answer, the pupil keeps the pair. If they are not a match they are turned face down and the next pupil gets a turn. This process continues until all cards are matched and the winner is the pupil with the most pairs. If a team member thinks that the selectors pair is not a correct match, they can challenge. Pupils are encouraged to check their books for the correct answer but the teacher also has a quick-check answer sheet. If the challenge is correct, the challenger keeps the pair. **Included in this Pack. ** 42 question and answer cards Teacher’s answer sheet.

Prior Knowledge Required Atoms are the building blocks of elements. All the atoms of one element are the same but are different to the atoms of other elements. Atoms combine to form molecules. If combining atoms are from the same element, a molecule of an element is formed but if they are from different elements, a molecule of a compound is formed. An element contains only one type of atom. A compound contains two or more different types of atom combined together chemically. Elements are listed in the periodic table. Each element has its own symbol. Some symbols are the capitalized first letter of the name of the element . Some symbols have two letters from the name with only the first capitalized.

Finish and reinforce a middle school module on breathing and the respiratory system or revisit it prior to exams with this innovative, enjoyable and challenging escape room lesson. Prior Knowledge Required Breathing is movement of air in and out of the lungs. Respiration is the release of energy from glucose. Breathing provides the oxygen for aerobic respiration and gets rid of waste carbon dioxide. Label the trachea, right bronchus, bronchiole, alveolus, intercostal muscle, rib, diaphragm. Label a diagram of an alveolus and show the direction of diffusion of oxygen and carbon dioxide. Experiment using limewater to compare the amount of carbon dioxide in inhaled and exhaled air. Compare the percentage of oxygen, carbon dioxide and nitrogen in inhaled and exhaled air. Mechanism of breathing. Changes in volume and pressure inside the chest during inhalation and exhalation. Evaluate a model of the mechanism of breathing. Students have to work their way through the clues to find the code to a combination lock on the school exam paper store in which the substitute teacher has been accidentally locked in the stationery store. The pack contains: PowerPoint – scene setting and instructions (sound effects and built-in timer); crossword; word search; dominoes activity; worksheet; code breaker sheet; answers; lesson plan. If time is limited just the crossword, word search and domino can be used. The worksheet is the most challenging clue to solve and this can be omitted completely for less able classes. Both 3 and 4 number combination locks can be purchased very cheaply online or the teacher can pretend to phone the school office for the staff to attempt to release the teacher.
