Autumn 1

Atomic Structure

Complete at least 2 from the following:

  4. Complete Activity 4 Subatomic particles practise
  5. Create a model of the atom. It could be using just paper, glue and scissors, or you could be more creative and find lots of different materials to use!

Autumn 2

Periodic Table

Choose any 2 from the following:

  1. Create a revision style guide to explain how groups and periods have been developed – this must include information about the electron configuration of each of the elements in particular groups. Your guide should be interesting and easy to understand.

You can use the following websites to help you:

Video clip: BBC Bitesize – Groups and periods in the periodic table

YouTube: How the elements are laid out in the periodic table

YouTube: Mendeleev and the Periodic Table

  1. Write a letter to Mendeleev that describes the differences between the early Periodic tables and our current Periodic table. Explain why the Periodic table has changed throughout the years.

You can use the following websites to help you.

Dynamic Periodic Table

Royal Society of Chemistry –Periodic Table (interactive)

University of Nottingham – The Periodic Table of Videos

  1. Prepare a short video presentation to show how to draw electron configuration for the ion of a metal (of your choice) include an explanation of how you work out its charge.
  2. Companies need special expensive processes to separate Helium from its compound. Write a letter to the helium balloon company explaining how helium is produced and why it is getting more expensive.
  3. Create a model of a group 1 or group 7 element, explain how its outer shell affects its properties.

 

Chemical Analysis 1

Complete at least 1 from the following:

  1. Use Google to find information on the ‘Hindenburg disaster’. Write a short piece on what happened to the airship and what caused the accident. Explain why modern airships wouldn’t suffer the same fate.
  2. Research chemicals used in the fireworks industry. Draw a table listing the names of some of the chemicals used and the effects they produce.
  3. Research why different elements produce different colours when heated. Draft a presentation which could be used to explain this to the rest of the class.
  4. Describe what ions are and explain how they are formed. Make a list of some common ‘an-ions’, (negatively charged), and ‘cat-ions’, (positively charged). Include both the name and formula of each ion. Explain why positive and negative ions are called ‘an-ions’ and ‘cat-ions’.

Spring 1

Reactivity of Metals

Complete at least 2 form the following:

  1. Use sheet 1 Elements of the Earth’s Crust to draw a pie chart of the most abundant elements in the Earth’s crust. Answer the Questions that follow.
  2. Complete activity sheet 2 Reactivity Series using internet research.
  3. Research the Blast Furnace and complete 3 Extraction of Iron
  4. Complete Activity 4 Alternative methods of Extraction
  5. Complete Activity 5 Corrosion and its Prevention

 

Reactions of Acids

Complete at least 2 tasks below:

  1. Create a powerpoint presentation that explains how salts are made using metals and acids. Your presentation should be at least 3 slides and include the following:
  • Description how to make salts from acids and metals
  • Full balanced symbol equations for making salts
  • Use half equations to describe oxidation and reduction
  1. Nitric acid is a common acid that is used to make nitric salts. Draw a cartoon to show how nitric salts are made from nitric acids. Hint make sure both the reactants and products are balanced.
  2. Create 5 challenging quiz questions about reactions between acids and metals to test the class.
  3. Write a poem, song or rap to summarise neutralisation using key terms that you have learned. Remember to make it memorable so that you can remember.
  4. Design an attention grabbing webpage that summarises what a redox reaction is and identifies which species are oxidised and which are reduced, in terms of electron transfer.
  5. Imagine that you are going to teach the class about how salts are formed, come up with a starter activity for the lesson.

Spring 2

Energy Changes

Complete at least 2 from the following:

  1. Research, and make a list of, some commercial applications of endothermic and exothermic reactions, such as sports injury packs, self-heating cans and hand warmers. Make sure you indicate the type of reaction each application uses. Select a product and write an equation for the reaction which is involved. Describe how this achieves the aims of the product, (for example how it results in heating a ‘self-heating’ can).
  2. Research the term ‘collision theory’ and use this to explain what must happen for a chemical reaction to occur.
  3. Research ‘bond energies’ and draw a table to show the bond energies of some common bonds, (for example, C-C, C-H, O=O bonds). Write instructions to another student explaining how to use these bond energies to calculate the energy transferred in a chemical reaction. Include a balanced equation of an endothermic or exothermic reaction as an example.
  4. Describe what happens during photosynthesis and write word and balanced equations to describe the process. State whether this is an exothermic or endothermic reaction and explain why.

Summer 1

Summer 2

Bonding & Structure 2

Complete any 2 from the list below:

  1. Create an A5 leaflet (fold a piece of A4 paper in half) or a c-fold leaflet (fold a piece of A4 paper into three segments), explaining the three states of matter and the differences between them.

Include an explanation of what happens during:

  • Melting
  • Boiling
  • Freezing
  • Evaporation
  • Condensation

Use diagrams to support the information you include in the text, and try to make the leafletvisually appealing.

  1. Choose an ionic compound, and draw a diagram explaining how ionic bonds in the compound are formed from atoms. Use the ionic bonding worksheet to help you.
  2. Write a song, poem or rap to explain what small molecules are and what typical properties they display. Make sure that your work catchy so you remember it!
  3. Choose a polymer from which many products used in everyday life are made. Using an A4 piece of paper, make a leaflet to explain how the properties of a polymer make it ideal for its purpose (for example: a new type of running shorts, insulation or plastic bag).

Use diagrams to show how its molecular structure is key to these properties.

  1. Research the different allotropes of carbon. Use the giant covalent structures worksheet to help you.

All worksheets are available from your teacher.
