I was learning to figure out problems including weight and capacity. I'm blogging this because I want to show my maths.
Weight and Capacity
Four problems to solve.
- Think what balance scales look like (image a see-saw)
Draw five diagrams of different looking balance scales and put on each side what might be being weighed
A school bus has a 2600 kg carrying capacity, How many people would it be permitted to carry? (think about the difference of child and adult)
Child = 30 KGs each
Adult = 70 KGs each
40 Children = 1200 KGs
20 Adults = 1400 KGs
1200 KGs + 1400 KGs = 2600 KGs
- I can see a selection of containers with a capacity bigger than 1 L but smaller than 2 L. What might the containers be?
1.5kgs , 1.1kgs , 1.2kgs , 1.3kgs , 1.4kgs , 1.6kgs , 1.7kgs , 1.8kgs , 1.9kgs ,
because the containers are bpthe filled with a kg and they are meant to be Litre containers.
- Make three different packages that have a mass of 1 kg. Compare the size of your packages and discuss why they can be so different but have the same mass.
1 kg of feathers , 1 kg of flour , 1 kg of rice bubbles
1kg of flour is heavier than 1kg of feathers because
They are all the same.
