Refreshing Experiments: Water Wall

One of the activities that we were suggesting doing during the summer was the “Water Wall”. A wall of water is a circuit mounted on a vertical wall made ​​up of different elements which allows the water to pass so that it will flow from the start to the finish. Through this system, the water flows through vessels of different sizes and through tubes of different lengths and thicknesses. The …

Experimenting with “Magical” Plastic

Lately Pinterest has become an inexhaustible source of inspiration. Some time ago I found several ideas on making ornaments with some plastic sheets, which in the heat of the oven, shrink and harden. Apparently these plastic sheets are marketed under the name “shrinky dinks “. But the best discovery was that you can find “home” versions of this plastic as they’re polystyrene sheets. Polystyrene is a plastic that can be …

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 …

Cars with Air Motor

A few days ago, we were talking about how many experiments with balloons you can do to learn physical principles. Today, we’ll insist on the same action-reaction principle we studied when we raced with rocket balloons, now using it to move some homemade cars with air motor. To build the car’s bodywork, we have several options. What we do is collect recycled material in a box from which the kids …

Lauching Water Rockets

This experiment follows on from our previous ideas for constructing rockets: a simple one with straws, and a slightly more complex one. Today we will continue with more aerospace science with the construction of water rockets. This will be particularly refreshing, not only because it will be outdoors but because we will use water as well as air. The rocket will be made from a 1.5 or 2 liter plastic …

Initiation to Aeroespace Science with Children

Aerospace science is not reserved just for big scientist and engineers: we can learn and practice the principles of aeroespace science with children. Today, we propose a couple ideas to initiate the little ones in the launching of air-propelled rockets. The first one is really simple and we based on this proposal to make it. We need a plastic bottle and a “rocket” that fits the bottle’s opening (the less …
