C3. Atomic Structure

This lesson covers an introduction to atomic theory. In includes a Power Point lesson covered the topics outline below. It also includes a revision or homework page (with answer sheet). A ‘Hot Seat Quiz’ that includes the key terms covered in the lesson and a printable of the key figures in Atomic Theory.

The Power Point lesson covers the key terms:
• Atomic theory
• Atoms
• Atomic structure
• Protons
• Neutrons
• Electrons
• Atomic Mass Unit

This is followed by a section covering describing atoms:
• Electron configuration
• Mass Number (Nucleon number)
• Atomic number (proton number)

The last section covers briefly
• Isotopes
• Relative Mass Unit
• Relative Formula Mass

atoms GCSE

This lesson cover the section C3 of the iGCSE unit 0653 combined science (some sections regarding the periodic table will be included in a separate section). It includes:

C3. Atoms, elements and compounds

3.3 Atomic structure and the Periodic Table

1 Describe the structure of an atom in terms of electrons and a nucleus containing protons and neutrons.

2 Describe the build-up of electrons in ‘shells’ and understand the significance of the noble gas electronic structures and of valency electrons (reference to noble gases not included - this will be in periodic table lesson)

3 State the relative charges and approximate relative masses of protons, neutrons and electrons.
4 Define atomic (proton) number and mass (nucleon) number.

5 Use proton number and the simple structure of atoms to explain the basis of the Periodic Table (see section C9), with special reference to the elements with proton numbers 1 to 20. (not yet included in this section)

C3. Physical and Chemical Changes

 CIE combined Science 0653 C3 Atoms Elements and Compounds.

This lesson covers the following topics
1. Elements
2. Molecules
4. Mixtures.
5. Physical and chemical properties
6. Physical changes and Chemical changes

The lesson includes a Power Point presentation including all the topics outlined above plus a quiz on physical and chemical changes

There is a lab lesson on compounds and mixtures (classic iron fillings and sulphur experiment) with word doc for students and teacher to follow.

The lesson also contains a separate homework exercise (word document)

Covers section first 2 specifications of C3 on the CIE 0653 GCSE Combined Science Course

Experimental Techniques- Chromotograpgy

 C2. Experimental techniques

1. Describe paper chromatography
2. Interpret simple chromatograms

This is a three part lesson. The first section defines what chromatography is. Next the principle of paper chromatography along with how it works  and the experimental set up and finally the last section covers how to interrupt the chromatograms. 

The lesson includes:
Slides on all of the above

the uses of paper chromatography (exercise)
Homework exercise with some answers (on a separate word document preview below)
As usual for all my lessons I have extra resources at the last page (including videos, notes, exercises and experiments)

2. Separating mixtures:  Solid and liquid -Filtration
                                   Solids - Evaporation
                                   Liquids - Simple distillation
3. Quiz
4. How to fold filter paper and diagram for how filter paper works
5. Homework page preview here!

Common Laboratory Equipment

While putting together the lesson on Experimental Techniques I thought it best to include some images of all the apparatus listed on the 0653 Combined Chemistry Syllabus Apparatus List.

By adding other labware, some videos a great flash card resource and a homework page it was been made into a complete lesson. Here is an example question from the homework page:

The Particulate Nature of Matter

Demonstrate understanding of the terms atom and molecule.

Just finished my lesson on the particulate nature of matter. Difficult to decide what to leave in an what to leave out! 

The finished presentation contains:
  • Definition of matter
  • A slide on the particulate nature of matter
  • Notes explaining how this theory explains the properties of solids, liquids and gases
  • Changes of states (melting evaporating and boiling)
  • Atoms
  • Molecules
  • Questions
  • Resources (video content related to topic, classroom experiments and exercises)
