I'm a science teacher at a secondary school. I love making resources. I put a lot of time into them, so like that as many people as possible find them useful. Please rate anything you find useful. Contact me with any questions.

(0)
This is an activity suitable for a lesson or as a piece of homework. It is designed to develop literacy and promote an interest and awareness in science. The students find a science based news story published in the last 7 days that they find interesting. They pick out keywords and find definitions for them. They research additional information and summarise the story in their own words.

(42)
Suitable for use as a starter or plenary. This is a one page diagram that the students are asked to complete. It asks the students to complete the path of a laser as it is reflected off a series of mirrors to a detector. They have to work out the angles of incidence and reflection. Requires a protractor.

WonderCalibanWonderCaliban

Titration investigation-Power station emissions

(0)
The aim of this experiment is to use results of a titration to perform a calculation linked to a real life example of measuring sulphur dioxide emissions from a power station. The scenario is that students are given a solution of sulfuric acid produced when waste gas from a power station is bubbled through hydrogen peroxide. They perform a titration the sulfuric acid against a known solution of sodium carbonate then use the results to calculate the mass of sulfur dioxide in the waste gas. Included in the PowerPoint is an introduction to the experiment, teachers notes, results table, instructions for students, advice on performing titrations and how to do the calculations. Depending on the group, different levels of support can be given.

Electricity generation-card sort

(0)
This card sort activity allows students to create a flow diagram explaining the processes in different types of electricity generation. They can also describe the energy transfers that take place. They can build flow diagrams for coal, oil, gas, nuclear, tidal, wave, geothermal, wind & solar energy.

Understanding atomic spectra - card sort

(0)
These are slides which can be printed and given to the students as cards for a 10 minute card sort activity to support a lesson on atomic spectra. It helps them understand atomic emission and absorption spectra in terms of adsorption and emission of photons by the electrons in an atom. Included is a pdf with 4 cards on each page and the original PowerPoint from which they were made.

WonderCalibanWonderCaliban

Bird Flu Pandemic in the USA - Interactive scenario

(1)
This is an interactive scenario which covers the US governments response when a bird flu outbreak spreads to the US from China in a global pandemic. The students are given key choices at each stage of the pandemic which affect the number of US citizens getting sick and the overall death toll. The tough choices can be used to encourage debate within your class and get students to justify their decisions. This can be used in either science, politics or history class and will last approximately 20-30 minutes. Provided are slides and accompanying worksheet.
