How to Make a Toy Boat

Today, we will show you a simple way to build a “self-propelled” boat. Or, in this case a boat driven by elastic bands. Surely, your children will enjoy designing it and testing it in the bathtub or in the pool during the summer evenings. A while back I found the idea here. Moreover this month we got inspired by the science-sparks website with a scientific challenge: the construction of a …

Engineering Project for Kids

Today we will propose an engineering project for kids in which starting from a construction game, they’ll learn about strength of materials and how by applying appropriate design techniques they may be able to increase the resistance of seemingly delicate materials. It’s about posing a challenge: to build a tower as tall as possible from two simple materials: spaghetti and marshmallows. Although the activity can be done individually, it is …

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 …

3, 2, 1 … Go!

Following on with the same idea from ​​the previous session, we‘ll build rockets powered by the force of air, but this time using a little more power. You can find the detailed instructions in Exploratorium. To build the rocket launcher, you need a 2 liter plastic bottle, a flexible hose that fits into the mouth of the bottle and a rigid tube which also fits into the hose. Connect the …

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 …
