This is an awesome crossword puzzle that would serve as an excellent starter, plenary or in-lesson activity for any periodic table and electron shells class. This crossword tests students’ knowledge of: Order of filling of electrons Position of elements in the periodic table Electronic configurations of type 2,8,2 (s,p and d orbitals are not covered) This is a lot of fun and my students loved it. The kids will literally have to hunt through a periodic table to find answers to clues such as: This element has an electronic configuration of 2,7 This element has an electronic configuration of 2,8,5 The first three periods of the periodic table are tested. In this pack you get a PPTX (which you can edit), a pdf version and a png of the puzzle itself (in case you want to project it on your interactive whiteboard for students to fill in).

This is a brilliant, two-page ionic bonding worksheet that is suitable for GCSE, IGCSE and MYP students.

The resource is ideal for GCSE or IGCSE students, and is designed to act as a fun way for the students to do the following: 1. Learn how to describe each part of their timetable (e.g. "On Monday lesson 1 I have Science") 2. Learn how to ask which lesson their partner has. For example, learning how to say “which lessons do you have on a Thursday?” Both students in the role play are given a timetable, with some blank spaces missing. Each student must describe their timetable to their partner, and fill in the blank spaces. Syllabus references: CIE IGCSE German: Area A2 (School routine). Edexcel GCSE German: Section One (High Frequency Language): Numbers, Time experessions, Times of the day; Days of the week Section Two (Topic Specific Language): Daily life. What school is like. Other IGCSE and GCSE exam boards also require knowledge and understanding of this topic.

It is basically a blank clock face with some German vocabulary on it. You may want to use it to test students or give as a homework. You will have to decide on the task that you can use this resource for.

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 fun (and moderately challenging) crossword puzzle that would serve as an excellent starter, plenary or in-lesson activity for any class about elements, compounds and isotopes.

Groups and periods in the periodic table, and how they relate to valence electron and shell number 3. The atomic definition of isotopes This is a lot of fun and your kids will love it. If your students have never learnt anything about elements, compounds and isotopes before, then you could provide the students with a summary to help them as they do the puzzle. In this pack you get a PPTX (which you can edit), a pdf version and a png of the puzzle itself (in case you want to project it on your interactive whiteboard for students to fill in).
