Lets 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 andsurgical 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 thestraw stays in place. (Make sure the straw does not touch thebottom 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 bottleand watch the mixture move up through thestraw.

THE WEATHERWORKSHEET 12A


24/36

THE WEATHER


EXPLANATION:

Why does this happen? Just like any thermometer, the mixture expanded when itwas warmed. This made the mixture no longer fit in the bottom of the bottle. Asthe surgical spirit expanded the coloured mixture moved up through the straw.

If the bottle were to get extremely hot, the mixture would have come upthrough the top of the straw.

PROCESS:

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

Put the stones or marbles into the bottom of the large half ofthe 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 outsidepart of the bottle. Make sure the numbers reflect the measure incm 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 iswaterproof.

Pour water into the gauge until it reaches the 0 line of thescale. (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 andbuildings. If it rains, the water will collect in the bottle.

Lets make an anemometerYou need: 4 small paper cups

Large plastic cup

2 drinking straws1 pinscissorsA staplerA sharp pencil with a rubber on the topPacking tapeSquare 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 andpush 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 inone direction and one facing in the other.

Staple the straws into an X shape. Attach them to the pencilrubber with the pushpin.

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

Put the anemometer outside (put some rocks on the thickcardboard to steady the instrument if necessary). Observe theanemometer 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 orslowing down (comparing the data collected with the previousones)

Now your anemometer is ready for use!

THE WEATHER

WORKSHEET 12D


33/36

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 orrotates, count the number of revolutions per minute (RPM). Next, calculate thecircumference (in cm) of the circle made by the rotating paper cups (ask yourteacher for help). Multiply your RPM value by the circumference of the circleand you will have an approximationapproximationapproximationapproximation of the velocity of at which youranemometer spins (in cm per minute).

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

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. Stickthe 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.
