This quick test/worksheet covers the pharmaceutical products testing section of IBDP Chemistry Option D (FE 2016). Questions include: 1. Testing drugs on animals and cell cultures tells us three things. What are they? 2. What does LD50 mean? There's also a flow chart to fill in (the docx file has the answers (just remove the boxes).

This worksheet provides ten questions that help the students to practice their skills in balancing redox equations by adjusting coefficients and by adding OH-, H20, and H+ where necessary. This worksheet is suitable for 'AS' - Level and IB Diploma Chemistry students. Syllabus reference: "Write ionic half-equations and use them to construct full ionic equations." (Edexcel 'AS' - Level Chemistry Specification, First Examinations 2014). Full answers are provided in this package. This is a perfect resource to use as a quick starter, plenary or homework. I have included both the pdf and docx files in this package. All images used have no attribution (they have been self-created or obtained from www.pixabay.com) '

After teaching and tutoring thousands of chemistry students over the years, I've found that the topic of ions tends to cause tremendous confusion (and is generally poorly understood).This is one of those fundamental topics that must be understood properly if students are going to learn about balancing equations, stoichiometry and advanced level chemistry later in in school. I created this resource booklet as a very clear way for students to understand the following: • What the period and group numbers tell us about the structure of an atom • What anions and cations are • How to use the group number of an element to figure out what kind of ion it will form Complete with full colour images, activities and answers; this booklet finally offers a clear and comprehensive explanation of this fundamental topic in chemistry. At the end there is also a link to a website, where students can take this topic to the next level and learn about ionic bonding and the formulae of ionic compounds. I've set the price at 2 pounds because this resource took a lot of time to create, and is of a very high quality.

This is a really clear PowerPoint that shows students how to use Hess's Law to solve problems. Includes a number of examples to help students see Hess's Law being used effectively. Printable and fully editable, this PowerPoint is suitable for advanced chemistry classes (e.g. 'A' - Level and IB Diploma)

A very clear PowerPoint presentation showing the 'arrows in boxes' electronic sub shell filling order from hydrogen to krypton. My students find this very helpful and it is useful when printed as a handout. It also shows clearly the incomplete 4s subshell in chromium and copper.

A PowerPoint presentation about how to balance chemical equations. Useful when printed as a handout or when used as an actual presentation.

A basic worksheet for high ability GCSE classes and introductory 'A' -level classes all about isotopes. Students have to fill in the number of protons and neutrons for different isotopes.

The is a MCQ test/worksheet on group 2 and group 7, suitable for Advanced Level Chemistry students.

A test on atomic structure, suitable for 'AS' - level students.

A quick test on atomic structure
