This Excel spreadsheet contains links to 48 fun and engaging science videos that are hosted on YouTube. These may be used for countdown timers, engaging starters or as instructional videos to accompany a main lesson activity. The spreadsheet can searched using a keyword for the topic that you are interested in. I have all of these downloaded to a hard drive (approximately 3GB of data) and am happy to make copies of these so please get in touch using my TES inbox.

This is an AS Chemistry lesson on the group 2 metal compounds and their reactivity and solubility at grades C to A. For grade C students write symbol equations. Note that the hydroxides and sulphates show opposite trends in solubility. For grade B they consider the aluminium sulphate Camelford water poisoning in Cornwall and write ionic equations. Note that all ions are aqueous and that Barium chloride and aluminium sulphate are soluble compounds. For grade A they analyse different data and use this to explain trends in solubility of group 2 compounds. For an engaging starter you could show the reaction of potassium with water and ask students to predict how the reactivity of group 2 metals would be different (less owing to increased charge density and 2 ionisation energies to make the ion).

This is a fun Chemistry tarsia on state symbols. There are 16 triangles with 18 pairs of questions and answers that make an equilateral triangle shape. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following chemicals: calcium carbonate, hydrochloric acid, water and carbon dioxide. The 'fjsw' file can be opened and modified with tarsia software. The tarsia software is free to download but there is not currently a version for Mac computers.

This is an AS Chemistry lesson on calculating which chemical is in excess in a reaction. Also students calculate an enthalpy change using a graphical method for reactions that happen slowly and therefore heat is lost to the surroundings when recording the temperature rise. The graphical method involves estimating the actual temperature increase. There is opportunity to use hand warmers for the starter activity and reacting magnesium with oxygen (i.e. in air) as a main activity. Please rate this resource and leave feedback.

This is an end of topic test that I have put together for GCSE Chemistry. I have created my own exam questions and resources as well as using freely available exam questions from past papers available online. I have created a detailed feedback sheet that students use to peer assess their work or the teacher can do this. It covers atomic structure and flame tests. A revision homework with questions and two model answers is provided.

This lesson forms part of the chemistry GCSE atomic structure scheme of work for the new 2016 AQA specification. The starter is a fun kinsthetic activity where students put element cards into groups. These cards are available to buy from Royal Society for Chemistry. A link is included on the slide. Alternatively students could make a pack of element fact cards for homework and bring them to lesson for the starter activity. Students are then introduced to Dobereiner and Newlands. They watch a 3 minute YouTube video about Mendeleev and answer the questions provided. Students then consider that Mendeleev missed group 8/0 elements and swapped iodine / tellurium so that the group 7 elements are all non-metals (i.e. why de not always put elements in order of increasing atomic weight). There is an activity where students consider the good and bad things about each scientists methodology and write an explanation for why we now use Mendeleevs table. Finally there is an exam question plenary. Please rate this resource and leave feedback.

This lesson is the third in the atomic structure scheme of work for the 2016 AQA specification. The two previous lessons are on elements, compounds and mixtures and balancing equations. The theme of the lesson is separating cannabis chemicals in order to extract TetraHydroCannabinol (THC). This is part of a group of chemicals called 'cannabinoids' and is used as an oral spray called Sativex that treats multiple sclerosis. The lesson starts with students listing 3 reasons for and 3 reasons against legalising cannabis. There is a YouTube video showing a 3 minute BBC News report that is embedded. The link is included in the PowerPoint. Students then use the separating mixtures trump cards to state what method they would use for each stage of extracting THC. They carry out a RSC practical to extract 'THC' (it is in fact a combination of chemicals) using a pestle and mortar and the solvent propanone. Though not included in the RSC practical they could filter the solvent to remove any solids. They then use paper chromatography to see whether their sample has a pure chemical. If the chemical is pure there will be a single spot visible on the chromatogram. Students could then dry their chromatograms and calculate the Rf value of their spot. Finally a higher level question is included at the end where students consider the effect of using different solvents. Please rate these resources and leave feedback.

This is is a lesson for GCSE chemistry that matches the AQA new 2016 specification section 4.1 - atomic structure and the periodic table. The lesson begins with a fun film characters starter. There is then a discussion on how elements are made in supernovae. Students then consider rules for naming compounds and how to write formulae. They then then write the formulae for 12 substances. The challenge is to write empirical formulae. The lesson concludes with a consideration of how some of the chemicals are harmful to fish such as Nemo. Titanium dioxide in suntan cream causes water and oxygen in seawater to react to form hydrogen peroxide that is toixc to fish. Answers are included. Please rate this resource and leave feedback.

This is a set of resources for one or two lessons (depending on the length of the lesson) on MRI and fMRI. This forms part of a scheme of work that includes NMR. The lesson starts with an ethical question of whether criminals are responsible for their actions - whether they are born criminals. The name of the criminal can be changed to suit local news reports or film characters. The lesson then considers the famous story of the railway worker Phineas Gage whose behaviour changed suddenly after an accident that damaged his pre-frontal cortex. Thus this brain region has been discovered to be responsible for higher level thinking and control. The lesson then considers how the brain can be imaged - beginning with anatomy then considering MRI and fMRI. Students then watch a 5 minute YouTube video on MRI and make their own notes. There is then a loop game plenary to check understanding. The second half of the lesson considers fMRI and its application in the law courts. Students consider the case of the murderer Brian Dugan who used fMRI scans as part of his defense to show diminished responsibility - he showed a lack of activity in some brain regions associated with emotion. They produce a presentation and then present this to the class. A markscheme for the presentation is included. Please rate this resource and leave feedback.
