These diagnostic questions and response activities (contained in the zip file) support students in being able to:

  • Recognise that a catalyst increases the rate of formation of new substances by increasing the rate of a chemical reaction.           
  • Recognise that increasing the surface area of...

The task shows a circle or radius r that just touches the sides of a right triangle whose sides are 3 units, 4 units, and 5 units long. A square is constructed from the right angle with length r so that one of its vertices is at the centre of the circle. Further lines are constructed from the centre of the circle...

  • Recognise that a reactant added in excess will still be present in the final reaction mixture.         
  • Recognise that some chemical reactions are reversible.
  • Recognise...

Di-deoxy sequencing is a way to determine the order of bases (A,C,G and T) in a piece of DNA. A set of 4 lanes (one for each base) is needed to sequence any given piece of DNA. Wherever a black
band appears in a particular lane that base is present. By reading off the order of bands across the four lanes the...

For her research, Veronika looked at how pine cones close when the weather is wet and open when it is dry. Pine cones do this to give their seeds the best chance of flying far away from the tree so that they can grow into new trees far away. In the rain, the seeds will not fly as far and will end up competing with...

In this Teachers TV programme, mathematics consultant Val Worcester joins Melanie Grant and Vanessa Clarke from Aston Tower, Birmingham as they reflect on the assessment activities used in their Key Stage One classes.
