Team:Dolphin Meteorologists
Objective:Measuring Weather
Our team has been collecting data on measuring weather. We measured humidity, wind speed, rainfall, barometric pressure, wind direction, and temperature. Here is our weather station and data collected by our team.
Our Weather Station

Wind Speed - Melia

Barometric Pressure - Akansha

Hygrometer (humidity)
How does our Hygrometer work?
A hygrometer measures humidity.
We created this using: a piece of cardboard, a dime, and a strand of hair.
We measured it by using a scale of 1 to 5, 1 being very dry and 5 being very humid
.
Observations:
When the air is dry, the strand of hair is shorter than when it is humid. When we observed the hygrometer, we noticed when it rained, the plastic point dropped lower than when it didn’t rain.

2. Wind speed meter
How did we measure wind speed?
We used: cups, straws, a piece of cardboard and a pencil.
How we measured wind speed was how many times a certain cup passed a certain point on the base in 1 minute.
Observation:
We noticed that only three days in two weeks there was more than one rotation per minute.

Wind Direction
What is a weather vane, and how did we use it?
To make the weather vane, we used needle and thread, an expo marker, a paper plate, a pencil, some blue painters tape and some clay.
How we determined wind direction was by placing the weather vane outside and recording the threads direction
We noticed that the wind usually blew south, and on most of the days that the wind didn’t blow south on, the wind blew west. Either that, or I was on vacation in Las Vegas.

Rain Gauge
What is a Rain Gauge and How Did We Use It?
*To make the Rain Gauge, we used a plastic water bottle that’s empty, a ruler and a Sharpie to mark the inches.
*We measured rain by letting the rain gauge stay in place outside and letting rain(if there was any) slide down the tube and drop into the container.
*We noticed that if it rains over a long period of time and the rain is heavy, it’s more likely to collect more rain than over a short period of time and to have less rain.

Barometric Pressure
A
barometer
is used to measure air pressure.We used a glass jar, a large balloon, a rubber band, and a straw. Observation:
When the straw was pointing up, there was rising pressure.
When the straw was pointing down, there was falling pressure.
If the straw was pointing to the middle, there was steady pressure.

Temperature
A
thermometer is used to measure temperature.We used a clear plastic bottle, water, rubbing alcohol, a straw, and modeling clay.
Observation:
The hotter it was, the higher the liquid rose. This was because the warmth made the mixture of water and rubbing alcohol expand.
The colder it was, the lower the liquid was.

We had trouble matching our data because we recorded at different times.
The entire team had to remember to record data every day. We had to ensure everyone was doing their part.
Collaboration was important for us to succeed.
YAY! TEAMWORKWe used Google Docs to record our data and put together our slides.
