Chemistry Workshops

DocumentsThe time has come for the upload of resources to the new site. There are links to each activity's 'homepage' from wherever in the curriculum we think it fits, and that homepage will have links to download experimental guide, teacher's and technician's guides, risk assessment etc.

Do be aware that just because we suggest something for a particular level, that is not prescriptive - you can use it for whichever level you like.

The documents are in MS Word (or powerpoint) format so you can customise them for your own use)

It would probably be useful, though to have a list of all of them in one place so you can see what there is. Here you are then.

It will be updated from time to time as new resources become available and I will try to highlight anything new.

Antioxidants: A Range of investigations based around the Briggs-Rauscher oscillating reaction to look at antioxidant levels in fruits and teas (though the method can be adapted for any antioxidant). (CfE level 3, N4, N5, H)

Biodiesel: A range of experiments based around the production and testing of Biodiesel from vegetable oil. (CfE level 3, N4, N5, H)

Bleaching Blue Food Dye: Reaction to determine rate constant and order of reaction from the bleaching of blue food colouring by domestic bleach. (At lower levels it can simply be used to look at the rate of reaction without the more complex mathematics) (CfE level 3, N5, H, AH)

Chemical Car: A novel way to look at rates of reaction. Construction of a 'car' that who's motor is linked to a LDR allowing for the car to automatically stop (or start) as the reaction mixture colours or fades. (Using a version of the iodine clock reaction). (CfE level 3,  N4) (At the moment the car construction is rather complex - we are looking for a simpler method)

Ceramics: A suite of activities to explore the properties of some ceramics. (Making polymer clay, natural cement, carbonation of concrete, porosity, effect of acids. More will be added as time goes on. (CfE level 4, N4)

(son of) Flash Chromatography: Flash chromatography carried out in a syringe - using talc (or cornflour) - can be used to separate samples of food dyes or plant pigments. (CfE level 3, N4, H)

Cobalt Complexes: Synthesis and analysis of amino-cobalt complexes (Including IR spectroscopy) (AH)

Colorimetry on the cheap:  Build and test a colorimeter using easily available materials for a few pence in about 15 minutes. No specific curriculum link for this workshop but colorimetry can be used in many areas of the curriculum.

Conductivity: Activity using a (home made) conductivity flask to follow neutralisation reactions. (N5)

Copper Etching: Activity using the displacement reaction between copper sulphate solution and zinc plate to etch a design. (CfE level 3, N4)

copper amino complexes: Preparation of isomers of amino copper complexes (and potential analysis by IR spectroscopy). (Preparation CfE level 3 (possibly) analysis AH)

Cyanotypes A simple photographic process using iron rather than silver compounds. (CfE level 3, H)

Dye Sensitised Solar Cells: An activity to show generation of electricity from plant pigments. (CfE level 3, N4)

Fizz pops: Using vitamin C tablets and bicarbonate of soda to follow a reaction rate. Reaction mixture is put into a film canister, water added and the lid put on. Time is recorded before it blows up. (CfE level 3)

Food Chemistry  - A series of experiments with supporting videos to illustrate some aspects of food chemistry (Mainly Higher)

Food Forensics - An activity using Solid Phase Extraction to take food colourings out of soft drinks and then other forms of chromatography to analyse them. (CfE level 3, N4, N5, H)

Guzzling Plants: An experiment and discussion activities looking at phytoremediation and the development of brownfield sites. (CfE level 3, N5 - and N4/5 Biology)

Hydrogels: A series of short experiments looking at the properties of hydrogels. (N5, H)

Ice NiceSome experiments into the chemistry of de-icing roads and runways. (N4)

Lemons: Investigating the effect of concentration and temperature on rate of reaction using lemon juice and permanganate. (CfE level 3)

Lip Balm: Activities researching and then making lip balms. (CfE level 3, N4)

Liquid Crystals: Making liquid crystals of different compositions and investigating the effect of temperature on theri colour changes. (CfE level 4, N4)

Ocean Acidification: An investigation into the causes and effects on the oceans of CO2 in the atmosphere. (AH)

Oranges are the only fruit: A look at the chemical resources that can be extracted from oranges (including limonene) and how this is an exemplar of the Circular Economy (CfE levels 3&4, N4, H, AH)

Plastic Fantastic: Synthesis and testing of an electrically conductive plastic - polypyrrole. (CfE level 3, N4, N5)

Polymer Slime: Making slime from borax and PVA glue - and looking at the properties and the composition varies. (CfE level 3, N4 & H?)

Rhubarb Rhubarb: (Similar to Lemons) Using rhubarb decolourising permanganate to follow the rate of reaction, looking at concentration and surface area. (CfE level 3, N5, H)

Rocks and Minerals: A series of simple experiments to make samples of sedimentary, igneous and metamorphic 'rocks'. (CfE level 3)

Rocks to Riches: Extraction of copper from 'ore' by leaching and electrowinning and analysis of copper content. (N4, N5, H)

Salt and Battery: Use of fruit juices and different metal electrodes to generate an electric current. (CfE level 3, N4, N5)

Shampoo: Activity to make shampoo, involving steam distillation to extract natural essences. (CfE level 3, N4, N5, H?)

Smart Materials: Some short activities looking at the properties of commercially available smart/novel chemical materials. (CfE level 3, N3, N5)

Spectroscope (DVD): Construction of a DVD spectroscope. Now with a new version that attaches to a smartphone. (AH)

Tea, Iron and Manganese content: Analysis of iron and manganese levels in different teas. (N5, AH)

Terpenes- A series of activities on Terpenes: extraction, analysis and reactions (H, AH)

Vinegar Cheats: Using a simple titration (with pipettes) to find out which samples of vinager have been watered down. CfE level 3, N4)

Vitamin C Drops: Determining the concentration of Vitamin C in a a variety of fruit juices using a simple titration with iodine. (CfE level 3, N4, H)

Vitamin C in Vegetables: Activity to determine the concentration of Vitamin C in fruit and vegetables by titration against DCPIP. (N4, N5, H)

Water Testing: A series of differing procedures to test for mineral content in water. boron, calcium, carbonates, iron, magnesium, nitrates, nitrites and phosphates. (N4, N4, H)
