cardboard funnel
string
shoebox
three straws
ruler
plastic bottle
small pieces of cardboard
pencil

Directions

Container
  1. Use sturdy cardboard to make a box big enough to hold several different weather instruments, and leave one side open.
  2. Paint the box to help protect it, and let it dry.
  3. Cut out another piece of cardboard to attach to the open side of the box with tape.
  4. Cut six slits in the door of the box to allow the air to circulate.
  5. Back to Top
Thermometer
  1. Get a glass bottle that has a screw top.
  2. With the help of an adult, make a hole in the top.
  3. Fill the bottle with ink-colored water.
  4. Push a straw through the hole you made in the top.
  5. Cut out a cardboard scale and use a ruler to make measurements on it.
  6. Attach the scale to the straw with tape.
  7. Make sure the water goes up the straw, and add drops through the straw if it doesn't.
  8. Back to Top
Barometer

  1. Get a plastic bottle and squeeze out all the air.
  2. Replace the top on the plastic bottle and slot a straw through a shoebox.
  3. Loop a piece of string over the straw, and attach one end to the bottle with tape.
  4. The other of the string will be attached to the middle of a triangular pointer. Attach the pointer to the outside of the box using a thumbtack and at the pointed end of the triangle, draw a grid on your box so you can see when the triangle moves up or down.
  5. The pointer will move as the air pressure changes.
  6. Back to Top
 
Wind Vane
  1. Put a pencil inside a cardboard tube.
  2. Cut two triangles out of cardboard to make the vane. One large triangle and one smaller one. Attach the smaller one to the end of a straw, and attach the other end of the straw to the larger triangle.
  3. Attach this construction to the pencil.
  4. Cut out a piece of cardboard that makes an arrow (as shown) for the indicator.
  5. Cut out a small circle of cardboard and place it in the straw, keeping it in place with the plasticine.
  6. Rest the point of the pencil on the small circle.
  7. Use a compass to mark north and south and be sure to set it up on   your weather base so the directions are still correct.

Rain Gauge
  1. You'll need a tin can and a funnel.
  2. To make the funnel, measure the diameter of the can and then cut a triangle with the longest side to the same size as the can's diameter. Then roll the cardboard to make a funnel.
  3. You can use the ruler to measure the rainfall, so keep it close.
  4. After it rains, hold the ruler vertically with the "0" in line with the bottom of the can, and measure (in inches) how much water fell. For example, if there is one inch of water it means that one inch of rain fell. Empty the can for the next storm, or keep a running total (just remember where you measured to the time before).

Putting It Together
  1. Use the diagrams and these instructions to help you put your weather base together.
  2. Set the box on one end so that the hinged door opens to one side (not up or down).
  3. The rain gauge is placed on top with the ruler beside it. After a rain, you can use the ruler to measure the amount of rainfall.
  4. The wind vane is placed on top as well, with part of the straw sticking through the box. So, poke a hole in the box (make sure it is only as big as the cardboard so no rain goes through) and put it through the cardboard a little ways.
  5. The barometer goes inside the box at the back. Place it so it is against the wall in one of the back corners. The triangle and grid should face so you can see them when you're looking in.
  6. The thermometer is placed at the other end of the box (inside). Put it in the front corner not occupied by the box.
  7. Now, find a good location that you want to measure the weather at, and put it there carefully (try not to make anything move; it might be better to find the location first and then assemble it).
  8. Close the door to your station and leave it for a little bit. Come back periodically to see what the weather is like. Compare what you find to what is forecasted in the news.
