Trimester 1 Challenge

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
An 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.
Hygrometer
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.
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.
Rain Gauge
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.
Thermometer
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.

Conclusion
The hard part of our project was not having
time to learn more. After all, we enjoyed
doing our project and studying it!
