Trimester 1 Challenge By: Roman Nayabkhil, Daniel Trampe, Martin Cao and Alex Rodriguez
Introduction Hi, our group’s name is Channel 25. The people in our group are Roman Nayabkhil, Daniel Trampe, Martin Cao, and Alex Rodriguez. We have made six weather instruments for the 1st Trimester Challenge. The instruments we made were the anemometer, barometer, hygrometer, wind vane, rain gauge, and thermometer.
Anemometer A n anemometer is an instrument that measures wind speed. It is made of five cups, two straws, a pencil, a pin, and construction paper on a cup. When the wind blows, it will push the cups and the cups will start spinning. The speed is the number of times the marked cup spin around per minute (rpm).
Barometer The Barometer measures Atmospheric pressure. It is made of a balloon, a straw, a jar, a cardboard box, and loads of paper. If there is high pressure, the air will push down on the tip of the straw and make the straw point to cloudy. If there is low pressure it will make the balloon deflate and make the end of the straw point to sunny.
Hygrometers measure humidity in the air. Our hygrometer is made of screws, hair strands, paper strips, a piece of plastic, a dime, and a cardboard box. The hair strand will shorten if there’s high humidity and it will stretch if humidity is low because moisture will shrink the strand of hair. Hygrometer
Wind Vane A wind vane is a tool that shows where the wind is coming from. We made ours of a piece orange plastic, a pencil, a sealing strip, a pin, a Styrofoam bowl, and a wine pourer. We placed a movable directionals, so you can adjust where North is pointing to.
The Rain Gauge measures how many inches of rain falls in a period of time. Ours is made out of a plastic bottle, test tube, and a piece of modeling clay. When we tested the rain gauge Alex squirt water in and Roman held the rain gauge, and we noticed it measured up to two inches. Rain Gauge
A thermometer is a tool that measures temperature. Ours is made of a container with alcohol and a straw patted with clay. Alcohol expands when the temperature rises, so it goes through the straw. When it is cold the alcohol goes down, because the alcohol contracts at lower temperatures. Thermometer
Us Testing Our Weather Instruments
The hard part of our project was not having time to learn more. After all, we enjoyed doing our project and studying it! Conclusion
