As a science teacher, it is also important that you pass this understanding to your students. There are a number of misconceptions that still dominate science classrooms today. For example, many people still believe there is only one scientific method that describes how science is conducted, or that there is little or no difference between a scientific theory and a hypothesis. Science is also a way of thinking and investigating.

Laboratory Techniques and Measurements Lab 1 Labpaq Laboratory Techniques and Measurements Lab 1 Labpaq 9 September Measurement Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes.

Another key measurement of this lab was to teach the student about density and how to measure it. Density tells us that it is defined as the mass per unit measure, in which as we know is most oven referred to as volume and is also used to describe how heavy something is.

Along with all the measurements and how to use them correctly that Lab 1 teaches us, it also presents to use how to record our data correctly using Labpaq lab techniques and measurements Figures. Significant figures are the number of digits that we may use including or excluding the zeros that we may be given with any number or solution.

There are many different rules in determining the proper number of significant figure in an answer. So we were given the number My Hypothesis for this lab was simple, can I or can I not make the proper measurements using the provided materials and measuring devices included for this lab.

Along with making the appropriate measurements, will I be able to use the rules I was taught and record my data with the correct significant figures?

This lab is all about measurements and recording them properly. The lab first introduces to use the measurement of centimeters, millimeters, and meters to measure different household objects in our everyday life. We were given the task to use the provided ruler and measure a CD, key, spoon, and a fork in centimeters and then convert our findings to give us the appropriate units of millimeters and meters for each object required in the exercise.

For example; in exercise 3 we were asked to weigh 8 grams of sugar and then calculate how many moles of sugar it really was. We were then able to use this molecular mass of the sugar that we then had to use to calculate and determine the molarity of the sugar solution that we were working on for exercise three.

The lab presented itself with great learning options for teaching us how to use and proper measure the different units of the Si system, but as easy as they are to learn there are many of possible solutions for error. Since this was the first lab the many of the students have probably done in a couple years, I see plenty of room for human error do to the lack of training or experience with most of the lab equipment required to compete this lab to the full.

For example, if the digital scale, required for most of the lab, is not tarred right, your numbers from your experiment are going to be way off.

One wrong calculation or measurement could ruin a whole exercise if not whole entire lab itself. In my conclusion for this lab was pretty accurate to my hypothesis. I was able to make most of the appropriate measurements with little to no error at all. I had trouble with the density at first seeing I have never used the method for calculating density.

After a few tries I was able to succeed in calculating all the appropriate calculation required for this lab as well as using the appropriate significant figures for all my answers in my lab right up.

Measurements are all around us in our daily life. We use some sort of measurement on a daily bases whether we know it or not. Without measurement or the SI units we would have no since of idea of how much something may way or weather or not the water was going to fit into a single are or space density.

The unit of measure is used so much throughout the world everyday that without it, the world would have no since of weight, mass, height, width, or any other unit from the Si family.

We use this form of description for almost everything living and non-living in our world today.Laboratory Techniques and Measurements Lab 1 (Labpaq) Essay Laboratory Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know, identify and use each other tools provided in the kit.

measurements are very close to this value, but as with all measurements, there is some uncertainty associated with them.

We can use a similar method called percent difference to compare two measured values. For example, let’s say a student does an experiment to measure the speed of sound in air and measures the speed as m/s.
