Lesson Planning of Conversion of Units of Capacity
Students` Learning Outcomes
- Convert liter into millilitres and vice versa.
Information for Teachers
- Capacity can be measured by using millilitres and liter.
- Liter is denoted as L and millilitre as ml.
- The liter was introduced in France in 1795 as “unit of measurement” which is derived from a French unit ‘litron’.
- One liter of liquid water has a mass of almost exactly one kilogram.
- Mill means 1000th part which is used for measuring small quantities.
- 1 liter = 1000 millilitres.
- Liters can be converted into millilitres by multiplying liters with 1000, so, ml = L x 1000.
- Milliners can be converted into liters by dividing millilitre with 1000 so, L = ml/1000.
- During this lesson the teacher should consult with textbook at each level wherein and whenever it is required.
Material / Resources
Writing board, chalk/marker, duster, plastic bottles of different sizes, a medicine dropper, water glass, syringe, a cup of tea, syrup, note book and textbook
- Ask the students: have you ever noticed how much water your bottle contains?
- Show them label of the bottle that it can hold 1 liter or 1000 millilitre of water in it.
- A cup of tea can hold about 500 ml of tea.
- A glass of water can hold about 250 ml of water in it.
Conversion from Liter to Millilitre:
Conversion from Millilitre to Liter:
- Repeat the key points that you discussed during this lesson.
- Capacity can be measured in liter and millilitres.
- Liter is used to measure capacity of large whereas millilitre to measure small products.
- Mill means 1000th part.
- Liters can be converted into millilitres by multiplying liters with 1000 so, ml = L x 1000 ml.
- Millilitres can be converted into liters by dividing millilitre with 1000 so, L = ml /1000.
- Satisfy the students if still someone have problem in understanding the concept.
- Convert the following capacities in the given capacities: as;
- 18. 3 L = ________ml,
- 215 ml = ________L,
- 29 L = ________ml,
- 33.3 L = ________ml,
- 55 ml = ________L
- Assign homework to further strengthen their concepts, as;
- Three students gifted three bottles of juice to their teachers of 1.5 litters, 1 litter and 500 ml. calculate the total quantity and convert the total juice in ml.
