Stage 3: Measuring Liquid Volume with Non-Standard Units This indirect comparison approach then leads to the third stage of measurement: measuring with a non-standard unit. Teachers can also address this misconception during the direct comparison stage by helping students realize that a taller container does not always hold more liquid than a shorter one. Teachers may directly address this misconception by, for example, having students pour out the same amount of liquid into two different containers. This is something that teachers need to keep in mind. We know that many young children judge the amount of liquid in a container based on its level (height of liquid) without paying attention to other dimensions of the container.

Importantly, the size of the two containers that receive the content of the original two containers must be identical to make a judgement. Reproduced with permission from Tokyo Shoseki publishing company, Japan. By looking at the height of the liquid in the two containers, we can decide which container had more liquid. One way to indirectly compare the capacities of two containers is to fill up both containers and pour their content into two identical containers. Stage 2: Indirect Comparison of Liquid Volumes If all of the water from the first container can be poured into the second container without completely filling it, then the second container holds more water. If it overflows, the first container is bigger, or is able to hold more water. One way to directly compare the capacity of two containers is to fill up one container and transfer that amount of water into the other. Stage 1: Direct Comparison of Liquid Volumes Below, we discuss experiences that can help students move through these stages. length, weight, etc), students benefit from progressing through the four stages of measurement with liquid volume. Just as with all measurement attributes (e.g. They are dosed the same as chewable tablets.The Four Stages of Measurement with Liquid Volume Repeat every 6 hours as needed.ĬHILDREN’S BENADRYL FASTMELTS. (Reason: regular spoons are not reliable.) Keep in mind 1 level teaspoon equals 5 ml and that ½ teaspoon equals 2.5 ml.

If you use a teaspoon, it should be a measuring spoon. If not, you can get a med syringe at drug stores. If possible, use the syringe or dropper that comes with the medicine. Syringes and droppers are more accurate than teaspoons. Look below the correct weight for the dose based on the product you have.
