Note: the main difference between Ruku/Legend and Torua/Titan is the depth of thinking. Make sure you explain the statements you’re making, don’t just make statements (this is what gets you high marks in Y11)
- Aim: why did we do the experiment?
We did the experiment, finding different chemicals commonly found in households and using universal indicators to find how acidic the chemicals are and litmus paper to find out which chemical is base and acidic.
- Equipment: what did you use for your experiment?
Safety glasses, Spotting tile, Litmus paper, Universal indicator, Household chemicals
- Method: what steps did you complete to get your results for your experiment? Make sure your steps are numbered (like a recipe)
I wasn’t there in the experiment I wouldn’t know.
- Results: Pictures + link to your results table
Wasnt there.
- Discussion: starting discussion questions (you can include more detail)
- Why did different household chemicals change different colours? Link this to the ions present.
Because of the
- How did you know if these chemicals were acidic or basic? Answer this question for both U.I and litmus
Because they’d turn the litmus paper blue if its base and red if its acid
- Why might Universal indicator (U.I) be more useful than Litmus paper?
To show the Ph of the household chemicals
- Conclusion: starting conclusion questions (you can include more detail)
- did all your experiments work – if they didn’t, why?
I wasn’t there.
- What could you do to improve your science next time? Think about the reliability of your data.
Because the universal indicator was already presenting the Ph of the chemicals the litmus paper didnt show up as much for some of the chemicals because the universal indicator was in the way, maybe next time we should use the litmus paper before adding an additional chemical.
