A comprehensive and enjoyable explanation of the cause and effects of air resistance. To reinforce understanding, the engaging animated PowerPoint also includes two simple but exciting labs to investigate firstly the relationship between the surface area of a parachute and air resistance and secondly whether streamlined objects travel faster in water. Sets of results are provided for students to draw conclusions should apparatus not be available. In addition to the PowerPoint, this fully resourced topic comes with a collection of thirteen worksheets, guided notes, activities and homework. All answers are provided. A one – page flow chart lesson plan shows where logical choices can be made between resources if time requires. This fully resourced lesson included an animated PowerPoint which: makes understanding air resistance as collisions between the front of an object and air particles very easy to understand; demonstrates why streamlined bodies reduce air resistance to travel faster; provides a visual explanation of the relationship between acceleration due to gravity, air resistance, steady speed and why parachutes work; investigates the relationship between the surface area of an object and air resistance; proves that streamlined objects move faster through water.

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.

An ideal science activity for the end of the Christmas term which promotes not only the concept of teamwork but also individually contributing to the success of a team. There are 56 science and Christmas trivia questions in this animated, interactive team quiz with built – in scoreboard for up to seven teams. All questions are pictorial and multiple choice. Team Rounds Each team will attempt their general knowledge team round of three questions. The answer to each question must be decided by the whole team. If a wrong answer is given, the next question goes to the first hand up and, if correct, that person’s team get to try the rest of the round. Each team will also have to solve the clues to identify a well - known phrase or saying. There are four lightning rounds in which team members consult to try to identify a slowly revealed person or landmark. Individual Rounds Four unscramble and identify rounds which consists of a picture which has been cut up and rearranged. This is an individual not a team round. Memory Test – questions on eleven objects which cross the screen then disappear. Memory Test – give coordinates of frogs which have moved around a pond. Finally, the ten - question individual bonus round. This round allows flexibility in terms of the time the quiz takes as not all the questions have to be attempted. The quiz therefore can last between 40 and 50 minutes. Why not have a look at my shop? Elf Off the Shelf Shop

A dominoes game with circuit symbols and descriptions, sketches and circuit diagrams of series and parallel circuits instead of numbers. Take your turn by matching a domino exactly or, for example, by matching a sketch with its circuit diagram. A fantastic way to consolidate learning at the end of the topic or during test prep. So enjoyable students will not realise they are learning Prior Knowledge Be able to recognise the symbols for a lamp, switch, voltmeter, ammeter, buzzer, motor and resistor. Be able to match the description, sketch or circuit diagram for the same series circuit. Be able to match the description, sketch or circuit diagram for the same parallel circuit. What You Get 70 dominoes Animated PowerPoint explaining the rules and how to play. Rules of the Game Each player selects seven dominoes from the top of the face-down pile and holds them in their hand like playing cards. The player whose surname begins with a letter closest to the letter A starts and play proceed in a clockwise direction. Dominos can be matched exactly, or a name can be matched with a symbol or descriptions, sketches and circuit diagrams can be matched. If a player thinks a match is wrong they can challenge. If the challenger is correct, they give a card from their own hand to the challenged player. If the challenged player is correct, they give a card from their hand to the challenger. If a player cannot play a domino, they pick up from the face down pile and can play if possible or add it to their hand.

A comprehensive and enjoyable fully resourced lesson on shadows and lunar and solar eclipses for middle school. What’s Covered The shadow of a point source only has an umbra but the shadow of a large point source has an umbra and a penumbra. If the light source moves closer to the object, the shadow gets bigger. If the object moves closer to the screen, the shadow gets smaller . A lunar eclipse happens when the Earth stops all, or some, of the Sun’s light from reaching the Moon. The Moon orbits the Earth once every 29.5 days. When the entire moon passes through the Earths penumbra it appears slightly darker (penumbral eclipse). If only part of the moon passes through the Earth’s umbra it is a partial eclipse. A solar eclipse happens when the Moon stops all, or some, of the Sun’s light from reaching the Earth A person on Earth, standing in the Moon’s umbra will see a total solar eclipse. A person on Earth, standing in the Moon’s penumbra will see a partial solar eclipse. When the Moon is at its furthest point from Earth, it no longer covers the whole surface of the Sun and an annular eclipse is seen from the umbra. The Moon’s orbit is angled relative to the Earth so the Sun, Earth and Moon are not often in the alignment needed for a lunar Eclipse to occur. When the entire moon passes through the Earths umbra it appears red due to refracted red light (total or umbral eclipse).

A comprehensive and enjoyable fully resourced lesson on white light, dispersion and color filters. What’s Covered The order of the seven colours of the spectrum Dispersion is the separation of white light into the seven different colors of the spectrum. During dispersion, red light is refracted the least and violet light the most. Dispersion is caused by the fact that each colour of light travels at a different speed in glass. Red, green and blue are primary light colors. Magenta, cyan and yellow are secondary light colors. Mixing two primary light colours gives a secondary light color. Mixing the three primary light colors gives white light. An object only reflects light the same color as itself and absorbs all the others Work out the color an object appears in different light color What’s Included Animated PowerPoint for teaching with exit ticket quiz Flip it (pupil writes questions to given answers) Anticipation Guides (combined starter and plenary) Foldable Cut and stick activity.

This is an engaging and enjoyable memory game on reflection in plane mirrors. 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.
