The chemistry of UV reactive beads provides activities from Key Stage Two to Post-16, using photochromic beads. The beads can be used to investigate the effect of temperature on the rates of reaction, where the beads are returned to their normal colour. At Post-16 level, the activation energy/enthalpy can be calculated using the Arrhenius equation. The resources consist of teachers’ notes for each Key Stage, a PowerPoint for the enthalpy practical and a spreadsheet of example data.
Monitoring nitrogen dioxide is aimed at Key Stage Four chemistry students. Nitrogen dioxide is a pollutant gas produced by the combustion of fossil fuels. It causes respiratory difficulties in vulnerable groups and levels are therefore monitored by the UK government. Roadside monitoring stations are now supplemented by satellite monitoring. This PowerPoint presentation shows the effectiveness of Earth Observation Satellites used to monitor global nitrogen dioxide levels. The images show how nitrogen dioxide levels can be correlated to major roads and to the working week.
Rockets and combustion contains a number of activities developed by the National Space Academy and teachers at the Robert Smyth Academy. The National Space Academy outline three activities: methane bubbles; whoosh bottles; and rocket motors. Methane bubbles and whoosh bottles both use combustion of methane in air to link to rockets. Rocket motors use solid fuel Estes rockets to heat water – students can calculate the energy transfer to the water by measuring the temperature change.
A methane powered space shuttle? gives students the task of calculating the volume per second of liquid methane that would be needed to power the space shuttle. The Rocket Fuel presentation gives some calculations for real rocket fuel to compare to the values for methane.
Enthalpy level diagrams requires students to calculate how much energy is released burning methane, using bond energies.
Party poppers, write the equation gives information that should enable students to write the equation for the reaction in a party popper. This equation can also be used for safety matches. Link to Saturn V launch.
Stars dominoes is a good revision game for GCSE Physics. Questions include topics such as luminosity, brightness and the link between colour and temperature of stars.
Sun structure requires students to label a diagram of the internal structure of the Sun and answer questions about heat transfer and pressure within the Sun.
