Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement

Explain TWO precautions that the learners must take to ensure that the results are reliable. In the investigation on transpiration‚ measurements of the distance travelled by the air bubble in the capillary tube were taken every minute. The opening of the capillary tube had an area of 4 mm2. Study the table below of the results obtained‚ and answer the questions that follow. Time (minutes)

of the reading process and it has a big presence in the classroom. Its importance became evident since the National Reading Panel (2000) pronounced fluency instruction and assessment an essential and was thus incorporated into the reading First guidelines of No Child Left Behind in 2002 (Shelton‚ Altwerger‚ &Jordan‚ 2009). Reading fluency has been defined in many ways; an outcome of decoding and comprehension‚ a contributor to both decoding and comprehension‚ the ability to recognize words

was laboratory techniques and measurements. The purpose of this lab was to familiarize ourselves with different techniques used in the lab‚ taking proper measurements‚ and how to use the International System of Units (SI). Throughout lab we learned about mas‚ volume‚ length and temperature‚ and to be able determine density and concentration. To be able to documents properly and make effective observations we must be able to understand the International Measurement System. Length‚ temperature‚ time

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring
