IGCSE/GCSE Isotopes, Relative Atomic Mass and Electronic configuration

IGCSE/GCSE Isotopes, Relative Atomic Mass and Electronic configuration

PPT 1 was created for the second part of a lesson following on from atomic structure. The objectives are to: * recall the structure of an atom in terms of the positions, relative masses and relative charges of subatomic particles * recall what is meant by the terms atomic number and mass number * Define the terms isotopes and relative atomic mass (Ar) * Calculate the relative atomic mass of an element (Ar) from isotopic abundances. It includes practice for calculating Ar and an edexcel exam question. I have included the video from fuseschool which I have used in this lesson. PPT focuses on electronic configuration with teacher led presentation. Students can then complete the electronic configuration for first 20 elements.

Ionic and Covalent bond properties lab

Ionic and Covalent bond properties lab

Have students use their knowledge of ionic and covalent bonding to identify two unnamed powders. Students will perform a series of experiments to determine the properties of two unnamed powders in order to determine which is ionic and which is covalent. Properties students investigate include: physical state, melting point, electrical conductivity, solubility and electrical conductivity with distilled water. Included: 4 page student lab worksheet List of equipment to order 4 page marking recommendations for teachers

Rainbow Measurement Accuracy Lab

Rainbow Measurement Accuracy Lab

Use this lab with your Science students to emphasise the importance of accuracy when measuring. Students will use measuring cylinders (graduated cylinders) to perform a series of measurements of coloured water, when they are done they will have created a rainbow in their test tubes. Worksheet includes questions designed to make students think critically about their lab technique. An equipment list is also included.

Moles of chalk lab

Moles of chalk lab

Students will use their knowledge of molar mass and Avogadro's constant to calculate how many molecules of chalk they used to draw a self-portrait. Students will start by weighing their piece of chalk, they will then get outside the classroom and use chalk on a surface to draw a self-portrait. Upon returning, students will weigh their piece of chalk again and will then calculate how many molecules of chalk they left on the surface outside. This is a great activity to break up a dry stoichiometry unit. Item contains: 1x instructions sheet, 1x formula sheet, and 1x equipment list.

AQA Trilogy- The atmosphere & using resources

RAG sheets for each of the Trilogy units. These are completed at the start and end of the topic to measure pupil progress. It is a good idea to print off and get pupils to stick into their exercise books. Other topics available.
