Some people think that schools should stop teaching students by using books, because students find them boring and that children can learn from films, TV, video games and computer instead. To what extent do you agree or disagree?

Ag0, Fe0, Zn0, Ag2O, Fe2O3, and ZnO nanoparticles were fabricated using environmentally benign, cost-efficient, and time-savvy techniques of green synthesis using Okra seed extract as a reductant and confirmed using UV/Vis, FTIR, XRD, and SEM-EDX techniques. The dye degradation potential of synthesized nanoparticles was tested against two different
dyes
, methyl Blue and violate. Effects of time, temperature, dye dose, NPs concentration, and pH were determined. Among all, Iron oxide and Zinc oxide showed the best results and entirely degraded the
dyes
in 3 hours,
while
silver oxide degraded 80% of the
dyes
after three hours. Iron and zinc NPs degraded 40%
dyes
after 3 hours,
while
silver NPs degraded 25% dye.

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
