Mark the container with north, south, east and west. Use the compass to determine the directions. To finish, take the weather vane outside where the wind might blow. If not, make the necessary corrections and try again. Blow on the weather vane to see if it can spin freely. Once the pin is in place and oriented correctly, then push the pin into the top of the eraser. Because the tail adds weight, the pin needs to be nearer the tail, rather than in the center, to balance. The wind will be blowing from the side, so the tail should be positioned to catch the wind. Insert the dressmaker’s pin through the straw about two inches from the tail, in such a way that the fan is oriented up and down. Add more soil as needed.Īn adult will need to supervise this step for young children. Push into the soil until the pencil will stand up on it’s own, with the top eraser at least a few inches above the rim of the container. Place the pencil upright in the middle of the soil, with the eraser end up. If you plan to use it for an extended period outside, you might want to consider laminating the tail.įill the container at least part way with soil or pebbles. If it doesn’t fit tightly, add a bit of tape to keep it in place. Slip the midline of the tail into the slits in the straw. Have the children color their decoration. Cut the index card or paper into a weather-related shape, such as a raindrop, a sun or a flat-bottomed cloud. Compass to find north, east, west and south, only one needed to shareĬut two slits across one end of the straw, about one inch long.Soil, pebbles or similar material to hold pencil upright in the container.Container about the size of a small flowerpot, or old flowerpot.Index card, piece of file folder or heavy construction paper (for tail of vane).A pencil with a sturdy eraser (support the vane).A plastic drinking straw (body of vane) – straight, not the bendy kind.Water temperature science has more information about thermometers, too. Watch the video to see how to make a simple thermometer in this post about water and thermometers. You may make a thermometer to see how one works, but you will probably need an outdoor thermometer to be able to take reliable readings outside. Hygrometer to measure amount of moisture in the air.Wind or weather vane to record wind direction.Outdoor thermometer to measure temperature.To make a weather station at home, consider the making or buying some of the following equipment: The scientists use the information they collect from many stations to make weather forecasts. They often group the instruments at one location, called a weather station. The weather has been in the news this weekend, so it might be a perfect time to build a weather station.īecause the weather changes from time to time and place to place, scientists use instruments to measure the weather conditions.
