PowerPoint that covers the following learning objectives: Explain why bond breaking is endothermic and bond making is exothermic. Explain why a reaction is exothermic or endothermic in terms of the amount of energy needed to break bonds and being released when bonds are formed. Calculate the energy change for a reaction, including the correct unit. Includes diagrams, explanations, examples, questions and answers. This is made for a GCSE chemistry class. If you could spare 5 minutes, please review this resource, to help my online presence grow! :)

Learning objectives: Define what is meant by an alkene. State the names and describe the first four alkenes. Describe a chemical test to show an alkene is present. Define cracking. Describe the process of cracking, including conditions.

Learning objectives: To be able to describe what a physical property is. To be able to define common properties. To be able to describe the properties of metals and non-metals.

PowerPoint that covers the changes of state between solids, liquids and gases for a KS3 level class. Includes diagrams, questions and answers.

PowerPoint that covers the following objectives: Define covalent bonding. Describe how covalent bonds form. Draw dot and cross diagrams to show covalent bonds in simple covalent molecules. This is made for a GCSE chemistry class. Includes questions, answers, diagrams, explanations and space for the teacher to model how to draw dot and cross diagrams if they wish (with the correct diagram on the next slide).

PowerPoint that covers the following learning objectives: Define the mass of an object. Measure mass of an object using a mass balance. Includes questions, pictures, instructions and a practical in which the students have to use mass balances to measure the mass of up to 20 objects. There are questions that ask students to add masses of objects together, substract masses and work out the difference. The results table, questions and space for answers are on the worksheet. This is for a primary/early secondary class. If you could spare 5 minutes, please review this resource, to help my online presence grow! :)

PowerPoint that covers the following learning objectives: Measure the temperature of a substance. Plot a graph of temperature vs. time. In this investigation, students will compare how a large beaker of hot water and a small beaker of hot water cool down differently. They will form a research question, hypothesis, fill in table of results, plot line graphs and form a conclusion. PowerPoint includes research question, hypothesis, method, graphs and conclusion.

Practice calculating atom economy with these tiered questions. Answers included. If you could spare 5 minutes, please review this resource, to help my online presence grow! :)

Quiz includes: Reactivity series Extracting metals Displacement Reactions Quiz is out of 28 marks, so half the lesson to do the quiz and the other half to go over answers. Mark scheme is included.

24 mark quiz on the following topics: Writing chemical formula for ionic compounds. Properties and structure of ionic compounds. Drawing ions and ionic bonding. Describing how ionic bonds form. Mark scheme included.

-Recognise hazard symbols and match the symbol to its meaning. -Describe safety precautions that should be taken when handling substances, based on their hazard symbols.

Learning Objectives: To be able to state the number of atoms of each element in a chemical formula with or without brackets. To be able to name compounds consisting of non-metals only and a combination of metals and non-metals. To be able to describe how to name a compound.

Learning objectives: To be able to describe how changing concentration affects the rate of reaction. To be able to describe how changing pressure affects the rate of gas phase reactions. To be able to use collision theory to explain how changing concentration or pressure alters the rate of reaction.

Learning objectives covered. Demonstrate how to separate crude oil into fractions in a school laboratory. Describe how the trend in viscosity, flammability, and boiling point changes as the length of the hydrocarbon chain changes. Describe how the properties of a fraction of crude oil make it appropriate for its use.

Learning objectives: Use key words to describe solutions. Describe observations when a substance dissolves including any changes in mass. Explain how substances dissolve using the particle model.

To define rate of reaction and the units for rate of reaction. To plot and use a graph to calculate the gradient to measure the initial rate of reaction. To calculate the gradient of a tangent to the curve on these graphs as a measure of rate of reaction at a specific time.

Define a catalyst. Describe how adding a catalyst affects the rate of reaction. Use a reaction profile diagram to explain in detail the effect of adding a catalyst. Investigate which catalyst is best for a reaction using a variety of catalysts and use sample data to plot a graph.
