The Water Cycle in a Bottle

We’ve been watching and discovering the different states of matter and how to move from one state to another. One way to understand all these changes is to look at the water cycle. A terrarium is an excellent laboratory where this whole cycle can be reproduced naturally. To make your terrarium, you’ll need a cut plastic bottle, with enough room at the top for the plant to grow. In the …

Heat Wave

Today, we’ll show you a simple experiment that is not only related to our meteorological project, but also as a part of a bigger project aimed at studying the effects of sun and heat. We begin by observing the effect of the sun on different materials. We chose several samples such as: a stone, a bolt, a colored wax crayon, a bit of cheese, a chocolate square, a jelly bean, …

Weather Station: Rain Gauge

We will explain today how to build a rain gauge to record rainfalls. We need a plastic bottle, scotch tape, a cutter, a ruler, a permanent marker and some small river pebbles. We can start by cutting the top of the bottle. We fill the bottom part with some pebbles (only some centimeters). The aim is to make the bottle heavier to prevent it from falling.   We must now …

Weather Station: Anemometer

We will continue today with the wind observation from our weather station building an anemometer that will let us know how hard the wind blows. We need two straws, a plastic or paper plate, 4 cups (also plastic or paper), a pencil with rubber, and a pin. And a heavy support, such as a can or a plant pot filled with sand and stones. We started glueing the two straws …

Weather Station: Weather Vane

In the last days, the weather has been changing: windy days followed by rainy days, high temperatures, fog, thunderstorms…so we have started a project of meteorological observation to try to find out later why these phenomena occur. The first step has been to build a weather station to start the observation and data registration. We started building a wind vane to know the direction the wind blows from. We only …
