Students are introduced to factors that affect melting points, focusing on how impurities can alter melting and boiling points. Students set up an experiment testing the difference in melting point between Steric acid and Paraffin by heating two samples up in a water bath above a bunsen burner. Students collect the data and present it in a line graph gluing text boxes to explain the plateau and increases in temperature. Students write a description of their graph using the prompt questions.

Students are introduced to the idea that moles are an amount of things similar to pairs and dozen. Using the PowerPoint student are introduced to Avogadro's constant and that a relative atomic mass in grams equals one mole of an atom. Students complete a experiment in which the rotate around the room to weigh different amounts of substances in beakers to calculate how many moles are present. Students use the mass of the beaker and the symbol formula (written on the side) to calculate the mass/mmr. Students practice rearranging the calculation.

In the first lesson students use the hook of Ramesses II and carbon dating to introduce the idea of isotopes. Following the PowerPoint, students test their knowledge with a series of questions. In the second lesson students use sodium as an example to explore the idea of relative atomic mass. Students run through calculating relative atomic masses from isotope abundances and use their knowledge to answer the questions.

The slides contain a series of thought processes and frameworks so teachers can model out load their approach for students to use during comprehension and reading of scientific ideas. The lesson could be adapted for other topics. This lesson focuses on an end of Year test including: Acids and alkalis, homeostasis, energy stores and transfers, the particle model and reflection/refraction. Lesson content -Students complete a recap quiz. -Students complete a reading task in which they synthesis the data to title paragraphs and write one question. -Students get into groups and circulate around the room reading an exam question, completing an answer, and folding it over so the next group cannot see their answer. Once back at their stations they draft a final answer to share to the class based on the class responses. -Meta cognition slides and exam style practice.

KS3 introduction to changes of state. Through a range of kinaesthetic activities (such as describe-draw-show tasks and role plays) students are helped through an explanation of each process which leads to one state of matter changing to another.

Students complete an end of topic solids, liquids and gases spelling test. Using some simple equipment students plan a simple thermometer that could test different temperatures. Students finish the topic by answering levelled questions related to the expansion and contraction of liquids.

Students are introduced to the problem of determining which substances are acidic or alkaline in nature. Students complete simple litmus tests on a variety of household substances to determine the strengths and limitations of litmus paper as an indicator.

Students are introduced to a fictional granny who's washing machine has broken down. Through the discussion of simple evidence students are made aware of hard water and the development of lime-scale. Students design an experiment that demonstrates how acid can be used to breakdown and remove lime-scale from washing machine parts and reveals to them the products of such acid-carbonate reactions. Students complete a range of levelled questions to consolidate their knowledge.

KS3 problem solving lesson to discover what caused a train to crash. Students develop an understanding of whether or not solids, liquids and gases can be compressed using a simple experiment. Students use the results from their experiment to explain whether air leaking into the brakes may have caused the crash.

Students are introduced to the environmental effects of acid rain within a community. Teacher burns sulphur in a gas jar of water and universal indicator to demonstrate acid rain in a jar. Students use a series of disguised buffer solutions and pH probes to collect enough data to discover which areas produce the lowest pH water samples. After the teacher demonstrates the production of carbonic acid and sulphuric acid students use pH probes to investigate different samples of water collected in the local environment (buffer solutions). Students use their results to identify which area has the lowest pH and begin to consider explanations for these findings.

Students are introduced to the idea of classification through organising various television programmes into their own chosen groups. Students in groups formulate their own tests they could carry out using a series of simple equipment to determine similarities and differences between rock samples. Eventually using their results to form rules that distinguish igneous, sedimentary and metamorphic rock types.

Students use a short clip from the Disney movie Frozen to apply their understanding of changes of state to a simple experiment which they cooperatively plan and complete.

Students are introduced to the gruesome effects of long term indigestion. Students use their previously learnt knowledge of pH indicators to design and carry out an experiment to test which indigestion tablet is most effective in reducing the acidity of stomach acid. Higher level students can begin to evaluate the method used to carry out the experiment as well as their conclusion in terms of validity.

Students are introduced to some evidence related to a winged dinosaur. Using this evidence to provoke questions students are introduced to the formation of sedimentary rocks and how this type of rock can occasionally lead to the formation of fossils. Students produce their own fossils using Plaster of Paris and evaluate their model.

Students are asked to think about all of the chemicals and substances inside the oceans of the Earth. After probably getting a few answers like "fish" students should move onto ideas such as salt, sand, and pollutants. Students recap the idea of filtration to remove insoluble "garbage islands" from the sea and are then introduced to the idea of evaporation to remove the salt. The use of producing fresh water from brine as well as salt is discussed. After completing a class risk assessment, students complete a practical experiment. Evaporating salt from "seawater" in an evaporating dish. Students write their conclusion and then improve using expert language.

Students are introduced to Robert Boyle's observations of Roses changing colour in different chemicals. Students test the idea of preparing a natural substance to test acids and alkalis by planning an experiment that prepares red cabbage as an indicator. Student complete a risk assessment and design a procedure for their experiment. Higher level students have the chance to evaluate their indicator in terms of effectiveness.

Students are introduced to a fictional scenario applied to their school where a criminal has broken into the school allotment and stolen vegetables (outrageous!). After a quick crash course into the types of evidence a forensic scientist could collect from the scene, students carry out an analysis on soil samples from a range of suspects to determine the identity of the vegetable thief. Students write a letter/report to their headmaster explaining their findings.

Students are introduced to a fictional scenario where fireman make a factory fire worse by adding water. Students produce their own theories from their own knowledge to suggest what could have caused the accident. Through teacher demonstration students are introduced to the alkali metals and complete a summary table that contrasts physical appearances and reactivity. Students write a report to the fire brigade suggesting how alkali metals in the factory could have made the fire worse.

Using fictional facebook profiles of Mendeleev and Laviousier to complete a literacy task introducing the periodic table
