Make a Beaufort Scale Spinner

To know what’s the speed of the wind, make this spinner.

The Beaufort Scale Fine-tipped markers Card Ruler Scissors Fastener Glue

InstructionsInstructionsInstructionsInstructions

• Cut out the two circles and glue them onto card. (these circles are a sample. You can use a plate to trace around and a ruler to draw the lines)

• Look carefully at the Beaufort scale and number the segments of the bigger circle from 1 to 12 (Note: 0 and 1 are on one segment).

• Make a simple drawing on the wide part of the segment to illustrate the wind speed.

• Under each drawing, write a brief description and the wind speed in Km/h • Cut out the V-shape part of the smaller circle. • Put the small circle on the bigger one, make a hole with a punch in the

centre of the two circles. • Join them with the fastener. • Go outside, look around and use the spinner to know the current wind

speed.

Let’s make a thermometer

You need:

• clear, plastic bottle (500ml. water bottle works)

• water

• surgical spirit

• clear plastic drinking straw

• modelling clay

• food colouring

• Index card

PROCESS:

Fill about 1/4 of the bottle full with equal parts of water and surgical spirit.

Add a few drops of food colouring.

Put the straw in the bottle, but don't let it touch the bottom.

Use the modelling clay to seal the neck of the bottle, so the straw stays in place. (Make sure the straw does not touch the bottom of the bottle.)

Glue the photocopy of the thermometer scale onto an index card. Stick the card into the clay, behind the straw.

Hold your hands on the bottom of the bottle and watch the mixture move up through the straw.

THE WEATHER WORKSHEET 12A

THE WEATHER


EXPLANATION:

Why does this happen? Just like any thermometer, the mixture expanded when it was warmed. This made the mixture no longer fit in the bottom of the bottle. As the surgical spirit expanded the coloured mixture moved up through the straw. If the bottle were to get extremely hot, the mixture would have come up through the top of the straw.

Let’s make a rain gauge

You need:

• 2 litre plastic bottle

• weights (stones, marbles…)

• Scissors

• Clear tape

• Clear packing tape (Airon-fix)

• water

• ruler

PROCESS:

Cut the plastic bottle where the sides start to slope up to the mouth. Put tape around both cut edges. The top part will act as a funnel.

Put the stones or marbles into the bottom of the large half of the bottle to stabilize it.

Set the funnel inside the bottle so the taped edges touch.

Copy or cut out the rain gauge scale and tape it on the outside part of the bottle. Make sure the numbers reflect the measure in cm and/or mm.

Make sure the “0” line is above the stones or marbles.

Put the clear packing tape (“Airon fix”) to cover the scale so it is waterproof.

Pour water into the gauge until it reaches the “0” line of the scale. (You will have to put water every day up to the “0” because of water evaporation).

Put the rin gauge outside in an open area, avoiding trees and buildings. If it rains, the water will collect in the bottle.

Let’s make an anemometer

You need: 4 small paper cups Large plastic cup 2 drinking straws 1 pin scissors A stapler A sharp pencil with a rubber on the top Packing tape Square of thick cardboard

PROCESS:

“Make a hole through the bottom of the large cup so that the pencil will slide through. Tape the cup onto the cardboard and push the pencil through the hole.

Cut off the tops of the small cups (they must be about 2,5 cm) deep. Colour or mark one of the cups in a different colour.

Tape or staple a cup onto each end of the straws, one facing in one direction and one facing in the other.

Staple the straws into an “X” shape. Attach them to the pencil rubber with the pushpin.

Push the straight pin through the two straws where they cross.

Put the anemometer outside (put some rocks on the thick cardboard to steady the instrument if necessary). Observe the anemometer in different situations. Watching the different cup, record the number of revolutions it makes in one minute.

With this measurement you will know if the wind is picking up or slowing down (comparing the data collected with the previous ones)

Now your anemometer is ready for use!”

THE WEATHER WORKSHEET 12D

THE WEATHER


EXPLANATION:

An anemometer is useful because it rotates with the wind.

If you want to calculate the velocity at which your anemometer spins or rotates, count the number of revolutions per minute (RPM). Next, calculate the circumference (in cm) of the circle made by the rotating paper cups (ask your teacher for help). Multiply your RPM value by the circumference of the circle and you will have an approximationapproximationapproximationapproximation of the velocity of at which your anemometer spins (in cm per minute).

Real anemometers measure wind speed in kilometres per hour (Kph). They convert the rotations per minute to a more accurate wind speed.

Let’s make an wind vane

You need: Thick cardboard Unsharpened pencil Packing tape Empty soup can Scissors A clay ball Pen cap A ruler A magnetic compass Stones, sand or heavy objects

PROCESS:

Cut an arrow shape out of a thick cardboard.

Cut a circle and make a round direction disk similar to the example provided. Decorate it and, if possible, laminate it. Make a hole in the centre of the disk. The hole must be big enough for a pencil to pass.

Push the pencil, rubber-side down through the hole in the direction disk. Stick the eraser end into the small ball of clay and put it at the bottom of the can. Fill the can with sand. This will make it stable.

Tape the pen cap onto one side of the arrow.

Put the arrow on top of the unsharpened pencil. The arrow must be level

If not, re-tape the pen cap. Make sure that the arrow spins freely. If it does not, use a different type of pen cap.

Your wind vane is ready!

THE WEATHER


Put the wind vane outside in an open area, at least 1 metre above the ground and away from high walls or trees. Use the compass to set “North” on the direction disk towards North.

EXPLANATION:

The point of the arrow will spin into the wind, indicating the way the wind is coming from. If the arrow is pointing to the west, the wind is blowing from the west.
