How to do Rainfall totals measurement as an easy science project
What is the rainfall total and its importance?
During the monsoon time, we get very good rainfall throughout the world. But we get some places huge rainfall and other places less rainfall. We are not going to discuss the cause of the rainfall difference. In this post, we are going to discuss an easy science project, how to measure rainfall totals. The measurement of rainfall is called rainfall totals with rain gauge. It is useful for easy science project for 6th and 7th grade student.

In addition, Rainfall totals give information on the rainfall of the entire 24 hrs. What is the need for rainfall totals measurement? As we collect information from the internet or books. The weather scientist collects information from nature. You may ask, what is the use of the collection of information from nature? The main collection of information from nature is to predict and simulate its behavior.
For example, the detailed study about the behavior of nature required for any nation's development. Thus, the rainfall totals measurement is useful in the agriculture and fishery sectors. However, these are not only sectors. In some cases, rainfall affects the economy of the nation.
Purpose of the rainfall total measurement experiments:
In this easy science project for 6th and 7th grade student, you will learn the variance of rainfall in different localities. Rainfall water collection give information about the rainfall total in a specific locality. The following materials are required for rainfall total measurement to easy science fair project.
Material required for Rainfall total measurement:
- Thermometer ----- one
- Rain gauge ----- one (medium size)
- Rain gauge ----- one (large size)

Standard Operating Protocol for rainfall total measurement:
- Take Rain gauge (large or medium) depends on the rainfall rate.
- Depend on rainfall, note the mm/m² in the record notebook.
- When the rain comes, note down the humidity, temperature and wind flow from google data or any weather website.
- If rainfall is heavy, then you empty the water from the rain gauge and add up the value in mm/m². (it is for heavy rainfall)
- If you have drizzling rainfall, then you replace the water from the rain gauge in mm/m². (it is for light rainfall)
Calculation of Rainfall total:
Rainfall total is calculated with the unit of a millimeter per meter square (mm/m²) or centimeter per meter square (cm/m²). The total adds up of these values from the cylinder is called rainfall total in 24 hrs. If you are measuring low rainfall total, you use the medium size or small size rain gauge. If you are measuring heavy rainfall total, you use the large size rain gauge. It is available in the marketplace.
Observation from Rainfall total experiment:
Generally, rainfall goes on for two to three months. But it is not the same for all places around the world. Rainfall total in tropical regions is higher as compared to other regions. The limitation of this experiment, it can be done only during the rainfall. You need at least rainfall total data from three localities. Then only statistical comparison of data is possible.
Clouds are formed by condensation of water vapor in the atmosphere with small micro size dust particles. it affects the weather and climate pattern of the world. The global atmosphere (pollution level etc.,) patterns influence local weather conditions in our areas.
Have you ever noticed yourself how on sunny, humid day water can start moving down the outside of a cold surface of your cool drinks? it is due to the condensation of water vapor from the atmosphere. Clouds are also formed from condensation. we discussed in our previous post on cloud formation in the bottle.
Can the shape of clouds in your locality predict the rainfall?
Rainfall and snowfall come from clouds. Clouds number, however, doesn't always indicate rainfall or snowfall. you can draw down the shape of the cloud in your notebook. You can make a statistical survey about the shape of cloud and rainfall with wind flow at a specific temperature.
You should create a chart of cloud shapes from the statistical survey. you record the cloud shape with videos or photographs. Minimum and maximum temperature of locality recorded in the notebook each day. Record in the notebook, it was windy or not and collect information from google or any weather website. you write down other weather conditions, such as if it was rainy, snowy, and sunny. you collect the data every day for one to three months.
If you visit the ocean near to your area, you observe lots of ocean breezes. Sometimes it blows towards the land surface, and other times it blows toward the sea surface. Generally, land surface areas near the ocean have a more moderate temperature than the land surface area away from the ocean. Ocean tends to be a little cooler when the land surface is very hot and a little warmer when land surface is very cold. This the ability of ocean to retain the heat exchange with the land surface.
You can present all this information as a chart and graphical poster in the easy science project for 6th and 7th grade student. you can plot the following graphs
- Days or weeks in the x-axis and rainfall total in the y-axis (cm's).
- Days or weeks in the x-axis and maximum and minimum temperature.
- Each day with the shape of the cloud (categorize the type).
- Days or weeks in x-axis and maximum and minimum wind flow.
- Days or weeks in the x-axis and humidity of the air.
- Compare different localities and rainfall total
In this blog, we mainly focus on science fair projects for kids, 3rd, 4th, 5th,6th, 7th,8th and 9th grade students. you can see more project ideas updates in our sitemap.
