A dominoes game with questions and statements game on separating mixtures including evaporation, distillation, fractional distillation, filtration and chromatography. Prior Knowledge Required The composition and physical properties of mixtures Evaporation to dryness and crystallisation Distillation Fractional distillation Filtration Chromatography What You Get 80 dominos Animated PowerPoint explaining the rules and how to play. Rules of the Game Each player selects seven dominos 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. Pupils are encouraged to check their books for the correct answer and consult their teacher if a consensus is not reached. 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. More high quality resources available here. Elf Off the Shelf Resources

This is an engaging and enjoyable memory game on separating mixtures including evaporation, distillation, fractional distillation, filtration and chromatography. 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. Please note – This pack is best printed in color. Included in this Pack 42 question and answer cards Teacher’s answer sheet. Instruction sheet Preparation Use double-sided printing to copy 1 set per group of 4 pupils. Sheets could be laminated to enable year-on-year use. Cut sheets into cards.

If the challenge is wrong the challenger moves back two spaces. In the event of a challenge, pupils are encouraged to consult their books but the teacher has a quick-check answer sheet. Prior Knowledge Required Metals are conductors of electricity and heat while non - metals are insulators. Metals are strong (have high tensile strength) but non - metals are not. Metals are shiny when freshly cut or polished but non -metals are dull. Metals are sonorous (make a ringing noise when struck while non – metals do not. Metals are malleable (can be beaten into shape) and ductile (can be drawn into wires) but non – metals are neither and are brittle (shatter when struck. Iron, nickel and cobalt are magnetic but all non – metals are not magnetic. Metals are heavy which means they have a high have a high density because they contain a lot of particles. Non – metals are not heavy. Metals are all solids at room temperature, except for mercury which is a liquid, as they have high boiling and melting points. Of seventeen non - metals, all are gases except for five which are solids and one which is a liquid. Both metals are non – metals burn in oxygen to form the oxide.

An ideal end-of-term activity or first-day team builder. This activity promotes the concepts of working as a team and individually contributing to the success of a team. It is a 65 question, animated, interactive team quiz with built – in scoreboard for up to seven teams. All questions are pictorial and multiple choice. A wide-range of topical and historical general knowledge is included. As well as asking a question, most slides also provide some interesting snippets about the topic so pupils are expanding their general knowledge as well as enjoying the activity.Topics include: geography history sport nature science astronomy astrology current affairs film art flags of the world famous people famous landmarks Each team will attempt their team round which consists of a science question and four general knowledge 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 gets to try the rest of the round. After the team round is the individual round. A maximum of thirty questions answered on a first-hand-up basis accruing points for the team.

A fully resourced, engaging, comprehensive and enjoyable lesson explaining the periodic table of elements. What’s Covered Elements are arranged in the periodic table in order of atomic number. Metals are on the left of the table and non – metals on the right with a zig – zag line dividing the two. Some of the metals touching the zig – zag are semi – metals or metalloids which means they have some properties of metals and of non – metals. Vertical columns are called groups and horizontal rows are called periods. Each period starts with metals on the left and end with non – metals on the right. The elements within each group have similar physical and chemical properties. Group 1 are the alkali metals. Group 2 are the alkaline earth metals. Group 7 are the halogens. Group 0 are the rare or noble gases. The central block are the transition metals. On the left – hand side of the table, reactivity increases as you go down a group and on the right – hand side of the table reactivity increases as you go up a group. Group 1: can be cut with a knife; must be stored under oil; low density – lithium, sodium and potassium float on water; form compounds which are solid at room temperature; form compounds with similar formulae – LiCl. NaCl. Group 7;are all colored; react with hydrogen to form acids; react with metals to form salts. Alkali metal + water  alkali metal hydroxide + hydrogen lithium + water  lithium hydroxide + hydrogen Group 0 are all inert gases – they do not react with other elements Transition metals; except for mercury, which is a liquid, are harder than group 1 metals; have high melting points; react slowly with atmospheric oxygen.

Finish and reinforce a middle school lesson on the properties of metals and non – metals or revisit it prior to exams with this innovative, enjoyable and challenging escape room lesson. Students must work their way through the clues to find the code to a combination lock on the school storeroom where a squirrel, who was found injured on the school campus, has been accidentally locked in its pet carrier while awaiting transportation to the vet for urgent medical treatment. The combination lock used is one of two bought by the school – one for the stock room and the other for a new escape room lesson being planned by the science department. Both are set to the same combination. The paper on which the combination was written for the escape room lesson has been lost but the department still has copies of the lesson.

A comprehensive and enjoyable introduction to atoms, molecules, elements, compounds, the periodic table, chemical symbols, formulae and naming compounds. What’s Covered All atoms of one element are the same but are different from 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. If combining atoms are from different element, 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. Elements are listed in the periodic table. Each element has its own symbol. Symbols can be the first letter of the name (capital), two letters from the name (capital then lowercase) or taken from the Latin name of the element. The formula of a compound tells you how many atoms of each element are in it. Working out the number of atoms of each element in a compound from its formula. Naming compounds with the groups CO3, SO4, NO3. Compounds containing only two atoms end in ide. Mono = 1, di = 2, tri = 3.
