Scientists use the metric system to measure matter. The meter is the standard unit used to measure length. Centimeter and millimeter are smaller than a meter. Kilometer is larger than a meter. We measured a variety of objects using meter tapes and rulers.
Liquids have a definite volume but take on the shape of their container. The main unit of measure for liquids is liter which is subdivided into smaller milliliters. We used beakers, graduated cylinders and syringes to calculate the volume of a cup of water. Then we estimated three different volumes of water and measured to compare our estimates with the actual measures.
Weight is the measure of gravitational pull on an object. We used metric scales using units of grams to measure weight. We used triple beam scales, digital scales, and balance scales to measure objects. We also used explorelearning.com to simulate weight on the moon and other planets.
