Introducing comparison of volumes in junior science. Plastic measuring cylinders with coloured liquids. Young children often see height as being a greater volume (more). This arrangement has two main sets to introduce the concept of measurement rather than height. 760 ml is twice 380 ml which is twice 190 ml in different sized cylinders: 32 ml in the 100ml cylinder is half the height of 32ml in the 50 ml cylinder: 16 ml is half 32 ml but is the same height in 50 ml and 25 ml cylinders: 5.5 ml is half the height of 16 ml but more than 2 times less liquid. Read L to R. liquids measure 760 ml, 380 ml, 190 ml, 32 ml, 32 ml, 16 ml, 5.5ml. Measuring flasks are 1000 ml or 1 litre, 500 ml, 250 ml, 100 ml, 50 ml, 25 ml, 10 ml. Made from unbreakable polypropylene for junior science labs. |
