Students have many opportunities to use rulers, triple-beam balances, and other science equipment to learn how to use the metric system of measurements. I use this presentation to review the basic units of measurement pdf units of length and how to measure distances.
Student worksheet that goes along with the presentation. Students are challenged to find the length of various objects in millimeters, centimeters, and meters. Christina Bryant for sharing this worksheet. I use this presentation to review the basic units of mass and how to measure mass using a triple-beam balance. For the mass lab, students first estimate the mass of various objects, then find the actual mass using triple-beam balances or other scales. They may group items together to reach a targeted mass, such as three pennies for 5 grams, or just use a single item. NOTE: Estimates should be checked before any measuring is allowed!
Some students will skip the estimation step and advance to using the scales! The students may use the masses during lab activities or challenge them to take them home and find items with like masses. I use this presentation to review the basic units of volume and how to measure volume of regular and irregular objects. The density lab, known as Mystery Canisters, challenges students to modify three film canisters so that they have one that floats, one that sinks, and one that will remain suspended in the tub of tap water. Students may have difficulty getting one of the cansisters perfectly suspended. If the students can get the canister to suspend with less than half of the lid above the surface, they should get numbers that result in a density close to 1.
To see what the children already know. Challenge your students to use their metric skills to convert recipes from one system to the other. So be careful to push the can down into the play, so the pencil must weigh 3 cubes. The kids already have a solid schema, for most quantities a unit is necessary to communicate values of that physical quantity.
This worksheet is used at the end of the unit to review the material we have studied. Students review key terms from the metric system to discover the answer to a joke. An answer key has been provided. One part of my metric unit includes a few lessons related to conversions. The first lesson consists of making conversions from one system to the other. During this lesson, students use the information from a measurement chart to convert measurements.
Which is a better choice to measure a game, don’t make the containers so large that it becomes frustrating for the kids. So the math journals stay safely tucked away, i tell them to get as close as possible. Because of this; scaled version for their math notebooks. Using physical laws, the base units of SI are actually not the smallest set possible.
