This is a graded task on the heart and circulatory system in format of a level assessed task used at KS3. There are graded keywords for students to use as well as clear graded objectives taken from the OCR Gateway B3 biology specification (current for 2013/14). The heart diagram can be cut out by students. The two website links are to a heart song and heart musical quiz - both are YouTube hosted. Feedback to my TES inbox please.

This is a lesson that was taught to year 7 and has KS3 levels 4-6. The learning objectives slide promotes AFL and regular checking of progress in lesson - see my other resources for an explanation. I used a visualiser to demonstrate the flower dissection to the class using Lillies. Feedback to rowan.savage@hotmail.com.

A template worksheet for students to fill in about different energy sources which can be used with National Geographic magazine's article 2004 'The end of cheap oil'. Refers to Admiral Hyman Rickover's 1957 prophecy of the end of oil. I provide renewable energy info along with this template.

This is a fun yet challenging GCSE Chemistry tarsia for revision of the paper chromatography. There are 16 triangles with 18 pairs of questions and answers that make a parallelogram. 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 topics: Rf value, adsorb, solvent, soluble and uses of chromatography. 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 a fun expanding brackets fun GCSE Mathematics tarsia. 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. The question and answer pairs are designed to be very similar so that students need to carefully think about what they are expanding and simplifying. 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 covers balancing equations skills for GCSE. This is lesson 2 in the atomic structure scheme of work for the AQA 2016 specification. The lesson starts with a recap of elements, compounds and formulae (lesson 1 in the AQA atomic structure scheme of work). The lesson then has a demo of the sodium and chlorine reaction. Students are then introduced to the rules for balancing equations. They can balance equations using the particle diagrams method that is included in the main lesson. Alternatively students could use the column method or use boiled sweets that are included separately. The challenge is to balance equations that use brackets and to balance half equations.

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 a lesson for A level chemistry on electrochemical cells. It starts with students constructing a fruit cell and combing four of these cells to make a battery that powers a light bulb . These are made from a whole lemon, piece of clean copper, piece of clean zinc, electrical wires, crocodile clips and light bulb. This could be shown as a demo if there is not much time. Students offer explanations as to how this works. They are introduced to the theory behind how batteries work, what a half cell is and notation for writing half cells and E-cell. The hydrogen / H+ / platinum reference electrode is then introduced as a standard that is used to compare the voltage different half cells. Reinforce the idea that platinum is used because it a very unreactive electrical conductor. Students then use the electrode potentials table (go through this) to write the voltage and reactions for different combinations of half cells. This could be set as homework instead. The lesson finishes with an exam question plenary. Please rate this resource 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.
