Volume and Capacity – Magic Potion

Today 3/4A you will complete the capacity task that 3/4J shared at assembly. You will pretend to be Witches and Wizards and will invent a magic potion. You have strict instructions from the head witch (aka Mrs Smythe), that your potion can only be 600 millilitres. You must think of 6 different ingredients to put into your potion. Unfortunately, if one of those ingredients is 100 millilitres the potion will explode. If you use more than 6 ingredients or if your ingredients don’t add to 600 millilitres the potion will also explode.

Instructions

  • The potion you create will need to be 600 millilitres. If it is under or over 600 millilitres it will explode!
  • You can use 6 ingredients in your potion. ONLY 6! Some ingredients you might use? Examples: blood, unicorn hair, frog’s skins, toe nails etc…
  • How many millilitres might each ingredient be if your potion is to be 600 millilitres?
  • You are not to have any ingredient equaling 100 millilitres. If they do your potion will not work and will explode.
  • Challenge yourself to think of other numbers you could use to reach 600.
  • You will brainstorm a way to get to 600 millilitres. Check your answer with Mrs Smythe.
  • You will then be given the measuring jug activity, where you are required to…
      • Give your potion a name, write each ingredient down the bottom and write how many millilitres each one is.
      • You will then put each ingredient into your jug and then you will colour it in.
  • Upon completion you can write a recipe for your potion. You must will list ingredients, method, what happens when the potion is taken and how it can be reversed.

Down The Drain – Maths Investigation

We are conducting a maths investigation to find out how much water is wasted when people brush their teeth. To complete this investigation we will need to use multiplication and understand capacity and how to convert mL to litres.

Step 1: Estimate how much water is wasted when:
a) A person brushes their teeth and does not leave the tap running.
b) A person brushes their teeth and does leave the tap running.

Step 2: Conduct the experiment for both a & b and record the results.

Step 3: Using multiplication, work out how much water is wasted in 1 day, 1 week and 1 year both a & b.

Step 4: Record your results in a table.

Step 5: Present your data in a comparative line graph.

Step 6: Publish your work with a results and conclusion about the investigation.
