A tape measure.
You can use a balance or scale to find the mass of a rock. Place the rock on the balance or scale and record the reading to determine its mass.
A magnifying lens would be handy for observing luster.
Scientists use a method called radiometric dating to determine the age of rocks on the ocean floor. This technique involves measuring the proportions of certain radioactive isotopes and their decay products within the rock to calculate how long it has been since the rock formed. By analyzing these ratios, scientists can estimate the age of the rock.
Scientists can use sedimentary rock to determine a fossil's relative age by examining the layers in which the fossil is found. The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. By identifying the layer in which the fossil is located, scientists can approximate its relative age compared to other fossils and rock layers.
To determine if a rock contains a fossil, you can carefully examine the rock for any visible imprints or shapes that resemble the remains of plants or animals. Additionally, you can use tools like a magnifying glass or a microscope to get a closer look at the rock's surface and identify any fossilized remains.
You can use a balance or scale to find the mass of a rock. Place the rock on the balance or scale and record the reading to determine its mass.
You could use a ruler or a measuring tape to measure the length of an object. Both tools have markings that allow you to accurately determine the distance from one point to another.

To measure the length of a hallway, you would typically use a measuring tool such as a tape measure or a measuring wheel. Start at one end of the hallway and extend the measuring tool to the other end, ensuring it is straight and taut for an accurate measurement. Record the measurement in the appropriate units, such as feet or meters, to determine the length of the hallway.
To determine the weight of a barbell, you can use a scale or a weight measurement tool specifically designed for barbells. Simply place the barbell on the scale or use the measurement tool to get an accurate weight reading.
