Today 4th and 5th class made some weather instruments to measure the weather. Among our creations we have a wind vane, a barometer and a rain gauge.

Wind vane: We used some laminated card to catch the wind and some straws/lollipop sticks to hold these on. We will place our different vanes in different areas around the school to compare parts that may be more and less windy and to see if the vane is always pointing the same direction in all locations. Will the wind change direction much during the day/week.

Barometer: We also made a barometer to measure the pressure in the atmosphere. We used a balloon, a straw, a glass jar and some paper card.

Anemometer: We designed and made an anemometer to measure wind speed and direction. We used some paper cups to catch the wind and spin. We will count the number of times the cups spin around to make a full rotation. To help us with this, we coloured one of the cups black.

Rain gauge: We used a plastic bottle with the top cut off to make a funnel. We marked our measurements on the side. We were very resourceful and borrowed some spoons from the staff room to dig a hole to sit the rain gauge into.

We will be observing our instruments carefully this coming week and recording our weather at the same time each day to ensure we are as accurate as possible.
