Tests and reinforces the principle of metal displacement by other metals (and carbon) on the first sheet. The second sheet then asks pupils to consider the practical significance of smelting and the fact that carbon (in the form of eg. charcoal) is a cheap and readily available resource that can be used to extract metals below it in reactivity series, whilst metals above it require the more energy intensive (and therefore expensive) method of electrolysis for their extraction.

A structured approach to investigating how altering the supply of air (and therefore oxygen) affects the time that a candle can burn for. This is a simple experiment, but it also encourages students to consider key aspects of scientific investigation such as independent and dependent a variables, calculating mean values and evaluation skills.

Worksheet that enables pupils to work independently to fill in the missing information about a range of elements, using the idea that a specific element can be identified if any one of four pieces of information are given. It says GCSE on the worksheet title, but it can also be used at KS3.

What makes this resource stand out, apart from the very clear explanations and examples , is the structured way that students are regularly given tasks to check that they have understood and can apply the knowledge and concepts being covered. This work is created by an experienced teacher and examiner who has a strong grasp of the key points within each topic and the requirements of the examination. Should you like this resource, then the author has currently produced similar resources for the following topics: Atomic structure and the periodic table Bonding, structure and the properties of matter Chemical changes

This worksheet guides pupils through a simple and fun experiment to compare the strengths of different magnets.

This worksheet guides students through a simple but fun experiment to compare the friction generated between different surfaces.

This worksheet helps to give structure and organisation to a pH testing experiment. You may have small samples of liquid in test tubes or dropping tiles and add drops of indicator or pH paper. Try to get a range of pH values. I usually use these liquids: Strong acids from hydrochloric, sulphuric and nitric. Weak acids from vinegar, lemon juice, orange juice, red or white wine on the turn. Neutral or thereabouts is water and distilled water. Limewater, sodium bicarbonate solution, soap/detergent solution and possibly milk for weak alkali. Sodium hydroxide and potassium hydroxide for strong alkali, whilst ammonia solution is perhaps borderline weak strong alkali.

This worksheet accompanies the alkali metals reacting with water teacher demonstration. Under no circumstances is this a student practical (just covering myself there), and should only be carried out by teachers who are fully conversant with risk control measures required for the activity . I usually do this after the Calcium experiment (activity worksheet also available from me on TES) to build on and complete the sub-topic of metal reactivity. You don’t have to have a worksheet with this experiment, as it is an exciting and highly engaging activity, but it helps to ensure that the key learning objectives of how the alkali metals react with water are focused on .

This worksheet provides the structure for pupils to carry out a practical investigation of the relationship between mass and weight and asks them to consider how this might alter in other parts of the solar system.

This worksheet encourages students to research and review a range of biofuels, identifying their benefits and drawbacks.

This worksheet guides students through the relevant observations in an experiment involving the heating of metals over a Bunsen burner. As stressed on the worksheet, this goes hand in hand with, and not as a replacement for, clear teacher guidance and supervision, as the risk assessment, particularly for the burning of magnesium, is significant issue . The concept that compounds are very different from the elements they are made from is the key focus (eg. a shiny, silvery metal reacts with an invisible gas to become a white powdery substance). The aim is for the students to have controlled, safe, fun finding this out.

A differentiated resource to help less confident students to learn about and review the basic properties of acids and alkalis.

Activity sheet to investigate the chemical properties of magnesium. Detailed safety instructions must be given by the teacher, as they will be burning magnesium, which is potentially very hazardous in terms of burns and eye glare. I usually do this activity prior to the Calcium experiment, which is also available from me on TES.

This ready made homework research exercise gives pupils the chance to apply their knowledge of conductors and insulators to real things at home. Encourage them to look for simple things at first, and perhaps give a couple of examples, such as curtains acting as insulators and the metal in radiators acting as a conductor.

This provides clear instructions and structured questions to get the pupils to think about their measurements and how they relate to the idea of insulation. A clear results table helps them to organise their data and calculate temperature changes, which will then provide the basis for their conclusions.

Revision questions to test and review the basic structures and roles of the digestive system , supported by a labelled diagram of the digestive system.

SEN or primary starter worksheet to get pupils to start to construct and understand basic food chains.

This is a worksheet to guide and help pupils to record their observations and predictions. Most likely used at primary levl and with SEN pupils. You will need to collect the woodlice beforehand, possibly with the pupils. Each group needs at least ten, and preferably twenty woodlice to get reasonably valid results.

This cut and paste exercise gets pupils to evaluate the typical features of internal and external fertilisation.

This extended worksheet guides students through a fun investigation to see what affects the friction between their trainers (or shoes) and their chosen surface. It is open ended in that they can choose from three possible variables and they are encouraged to understand the concept that one factor should be varied to achieve a fair test, and also to evaluate the data obtained.

Suitable for SEN and above, with level of support adjusted accordingly . This worksheet would be best utilised at the end of a sub-unit of work on the digestive system, as the answers are not given on the sheet. The pupils are, instead, encouraged to look in their notes, textbooks or online for the basic information required.
