How does a barometer work? – using a barometer to record data

In learning How to make a Barometer, you will need to learn how to use a barometer to record data. Recording data in learning how does a barometer work, do the followings:

• divide each piece of graph paper into seven columns, one for each day of the week.
• to keep the data accurate, tape the paper to a wall and place the bottle close by on a flat tabletop.

• Position the bottle in front of the first column, say, Sunday, so that the straw’s red point almost touches the graph paper.
• At the time of day you make your regular temperature, wind, and precipitation measurements, note the position of the pointer and make a small pencil mark on graph paper.
• Move the bottle to the next column.
• Repeat this procedure each day for the duration of your weather window.

How to read a barometer?

In learning How to make a Barometer, you must also learn how to read a barometer. The first thing to do when learning how to read a barometer is to: watch your barometer work each day.

• When snow or rain is likely, the air inside the bottle will be heavier than the air outside the bottle, and so the balloon will stretch out a little, dipping the pointer down.
• A nice day means the air outside the bottle will be heavier than the air inside the bottle and the balloon will press down into the bottle, moving the pointer up.
• Each day, mark the barometer’s pointer’s position on graph paper.
• After the first week, remove the graph paper and replace it with a fresh piece of graph paper for more barometer readings and recordings.
• Connect the dots with lines to create a picture of air Pressure patterns.

How to make a Barometer

Do you want to learn how to make a barometer? How to make a barometer science experiment is a Middle School Science Labs experiment which means it is more involved than a regular Fun Kid Experiment.

Learning how to make a barometer can be very rewarding. By learning how to make a barometer, you will learn much about air Pressure as well as walking out of a middle school science lab with a working barometer for yourself as a souvenir.

Before we show you how to make a barometer, let’s examine what a barometer is and how does a barometer work.

What are barometers? How does a barometer work?

Barometers measure air Pressure and provide information about changing weather pattern. A high Pressure system barometer usually indicates fair weather without precipitation and a low Pressure system suggests warmer clothing and possible precipitation. The date you collect from a barometer may be the first warning of cooler temperatures, increased wind and precipitation to come.

What you need to make a barometer

In learning how to make a barometer, you will need:

• medium glass jar with small mouth
• Balloon
• Drinking straw
• 4 pieces of graph paper
• Rubber cement
• Red marker with narrow point

How to make a barometer step – by – step

To make a barometer, follow the steps below:

• Flatten the straw 1 inch (2.5 cm) from the end.
• Cut diagonally from the corner of the flattened end to create a sharp, quill-like point.
• color the tip with a red marker.
• Cut the balloon in half and stretch the balloon across the jar’s mouth, securing it with a rubber band to create a tight, drumlike surface.
• Apply a strip of rubber cement along the stretched balloon from the center of the bottle’s mouth to the edge and carefully place the unflattened end of the straw there, holding it in place until the glue dries.
• The straw should stick out about 6 inches (15 cm) perpendicularly from the bottle.

Middle school science labs experiments are more complicated than fun kid experiments or Science Experiments for young children. However middle school science labs experiments can be even more fun and definitely more challenging. Middle school science labs experiments involve more advanced Science Experiments techniques and the results of selected middle school science labs experiments will be more than impressive for cool science fair project experiments.

The scientific methods for most of the middle school science labs experiments are more advanced scientific methods than those fun, Cool Science Experiments aimed for children of any age. Some of the middle school science labs experiments require some prior knowledge of other Science Experiments.

Below are some great middle school science labs experiments you may want to try. They are Cool Science Experiments.
