I am a Science and Chemistry teacher focused on Cambridge IGCSE and AS/A. I am also heavily involved in the National Chemistry Olympiad program. By way of background I have a PhD in inorganic chemistry and entered teaching after 13 years in the food industry. I guess I am a bit old fashioned - I don't use twitter and I have no idea what instagram or Pinterest are......but I love my subject and I love working with students.

Chemistry: thermochemistry: using q = mCΔT and Hess's law

(0)
There are 2 worksheets (and answers) as well as notes and worked examples (ws2). WS1 has 2 pages of questions where the student has to choose whether a reaction is either endothermic or exothermic, draw and label an energy profile. There are also some simple calculations to determine the amount of energy given off from a known mass of an organic compound. WS2 contains notes, worked examples and 10 problems (and answers) focused on the equation Using q = mCΔT and Hess's law. The problems will be useful for students enrolled in Honors, AP or those who would like to sit the National Chemistry Olympiad competition. The problems are of straight forward to moderate difficulty. Key words: Hess's law, thermochemistry, enthalpy, heat, thermodynamics, calculations.

Biology: ecology - matching kingdoms and definitions

(0)
This resource consists of two activities. The first requires the students to cut and match the 5 Kingdoms, the definition and a picture (answers are given in the other document). The 2nd activity gets the students to cut out some descriptors and organisms and group them into different phyla.
Physics: motion - v =d/t and a = v/t problems
DrogchemDrogchem

Physics: motion - v =d/t and a = v/t problems

(0)
This resource contains 2 worksheets (6 pages of varying problems) and answers. ws1: calculations using the equation v = d/t including rearrangement. Some problems ask the student to convert different units (eg seconds to hours). ws2: calculations using the equation a = v/t. The problems include interpreting graphs, drawing graphs, calculations and unit conversions. It is 4 pages long so fits a fold A3 page. The problems would suit students interested in AP or honors. All questions are based on metric units.

Chemistry: balancing equations involving metals and their salts

(0)
This resource will be useful for teachers new to the profession or those with limited experience teaching chemistry. It contains * notes for the teacher including a 4-6 period lesson plan and template for practicals (5 pages in total); * a simple power point presentation with 13 slides that gives step by step instructions on how to balance equations. Reactions are limited to group 1 and 2 metals and their associated oxides, hydroxides and carbonates; * 4 worksheets (and answers) for word, symbol, and also word and symbol problems. The worksheets (and answers) can be found as separate resources if notes and lesson plans are not required.

DrogchemDrogchem

Chemistry test- 14-16 yr olds

(0)
This test comprises about 45 marks worth of short answer questions (4 pages long). The focus is on the periodic table, electron configuration, balancing simple word and symbol, equations, universal indicator colors and a few questions concerning the electrolysis of NaCl. Answers are included.

Biology: using a microscope and preparation of a sample slide

(0)
This resource has 4 related activities and a short (20-30 minute) 2 page test. There is a template microscope that can be labelled; a fun-worder on microscopes and plant cells; a handout for the students to use regarding sample sample slide preparation (2 pages) and a cross word puzzle. The 3-slide power point tries to show relative size by comparing images of viruses, sand, sugar, bacteria etc A stand-alone microscope slide template is also included should a teacher need to use different labels or use it in an exam.
Periodic table fun-worder (including atomic numbers) and other activities
DrogchemDrogchem

Periodic table fun-worder (including atomic numbers) and other activities

(0)
This resource contains two fun-worders based around the first 20 elements of the periodic table. In the first fun-worder, the student has to find the element. Each element succeeds its atomic number (find the name and you find the atomic number). The 2nd fun-worder has both the proton number (before the word) and the atomic mass (after the word). The student then fills in the periodic table grid (supplied) in the correct order. The students love these activities and it can take a good 45 minutes to complete. It is fun and builds familiarity with the PT. Other shorter activities are included: match symbols and names, and electron configuration practice.

Chemistry: test REDOX - 1 hour

(0)
This test is about 1 hours long. It includes questions about calculating oxidation number, observations and balancing half and full REDOX equations. This test would be useful for students doing AP or Honors chemistry. Answers are included.
Chemistry: balancing word and symbol equations involving metal salts with acid
DrogchemDrogchem

Chemistry: balancing word and symbol equations involving metal salts with acid

(0)
There are two worksheets (with worked answers) in this resource. WS1 focuses on word equations and limits reaction to those of oxides, hydroxides and carbonates. Notes are also provided. The intention is for students to get used to the idea of always writing down the salt and that water is the other product. WS2 asks students to balance the symbol equations. The equations are limited to acids reacting with oxides, carbonates and hydroxides. Both worksheets are also part of a larger resource called "Chemistry: balancing equations involving metals and their salts". This resource will suit students learning about balancing equations for the first time.

Chemistry: Lewis structure and molecular shapes problems-ws1

(0)
This resource has a set of notes with worked examples to explain how to determine Lewis structures, molecular shapes and formal charges. The accompanying worksheet uses these skills to predict shapes and reason the bond angles. Some problems are based on the comparison of two molecules.
Chemistry: pH calculations of strong acids and bases
DrogchemDrogchem

Chemistry: pH calculations of strong acids and bases

(0)
This resource consists of 2 worksheets: 25 calculation problems (and worked answers) involving aspects of acid base chemistry and some general pH calculation notes, which initially cover simple calculations. . The first half of each work sheet covers pH calculations in both acid and base conditions and calculation of H+ and OH- ion concentrations. The 2nd side of the worksheets focus on pH calculations involving partial neutralisation reactions where the student has to work out what species is in excess before calculating the pH. Some problems also involve the use of n=m/M equation. These problems would suit students interested in Honors, AP or wanting to enter the National chemistry Olympiad competition.

Chemistry: Balancing REDOX equations: notes and problems

(0)
This resource consists of some general REDOX notes, which outline how to balance REDOX equations and 2 double sided worksheets (and answers). The exercises include oxidation number elucidation, balancing half equations and balancing full equations. This resource would suit students who want to progress in the Honors program.
Chemistry: balancing difficult REDOX equations
DrogchemDrogchem

Chemistry: balancing difficult REDOX equations

(0)
This resource consists of some general REDOX notes and 1 work sheet with 6 hard-to-difficult REDOX reactions to balance. The difficulty is due to the fact the students must first convert word equations into symbols. One problem requires them to balance under alkaline conditions and the metal product is not immediately obvious. The problems introduce the students to uncommon reactions where the acid itself is converted to products other than hydrogen gas. This worksheet would be suitable for students doing AP, Honors or wanting to take part in the National Chemistry Olympiad competition.
