Oranges
Measuring is about making a comparison between what is being measured and a suitable measurement unit. Central to the development of measuring skills is lots of practical measuring experience. Also important is the reality that measurement is never exact.
Required Resource Materials:
- Oranges
- Measuring equipment including; rulers, scales, measuring jugs.
Activity: Complete the questions below:
- How can you measure an orange? (there will be multiple answers for this, list as many as you can think of). Weight,Length,Width,Capacity.Think of the attributes of an orange eg juice. Juice and inside
- Choose two of these attributes of an orange to measure and carry out the task. Write up a proposal for your investigation, including details on:
- Attribute being measured
Juice and inside
- Equipment required
Knife, chopping board, cup and spoon
Method (step by step)
Cut orange
Squeeze the juice out of the orange 220 weight of insides 50 mls juice
Measure the juice
Peel out the inside of the orange
Measure the inside of the orange
How will you present your results?
Google doc
- Write up your results
- What were successful/unsuccessful approaches to measuring each of your chosen Attributes? Why? I think that squeezing all of the juice out of the orange was a bit of both as it made a mess but we got most of the juice in a container.
- With the inside of the orange I think it didn’t go very well because first using a spoon didn’t work but then we tried a knife and it kinda worked. 220 weight of insides 50 mls juice
- Choose 4 other objects to measure in the class - use 4 different measurements eg measure the length of something and the weight of something else. Write up your results in a table. Pencil-length=17cm book-width=20.5cm scissors-weight compare with 4 highlighter= highlighter are just heavier drink bottle- capacity= 760mls
My next step is to have a teacher conference and find a new goal
