Today we will talk about another classic. More than an experiment, it is just a simple science demonstration which only aims to be a trick to entertain the kids and for sure also some adults. We use balloons in many of our experiments, and this could be a great start for a science session to catch our students’ attention before starting with a different activity. The idea is to pierce …
Today we will talk about an extension of the experiment of the rubbery egg. In that experiment we soaked an egg in vinegar to make the shell disappear. The shell is removed by the reaction between acetic acid in vinegar and calcium carbonate in the eggshell. Today we will start from this rubbery egg to continue with our experimentation: You need to soak the rubbery egg in colored water (we …
We would like to show you again some ideas about how to introduce scientific concepts on a entertaining and funny way. We will play today with magnets with the little ones to discover the force of magnetism. First of all a very IMPORTANT WARNING: remember magnets are very dangerous if accidentally swallowed, so always use large magnets specially designed for small hands such as magnetic bands or horseshoe magnets and …
We like to create our own toys, we like to reuse waste materials and of course we like science. If it is the case also for you, you should try the “magic can”. You need a large can with lid, a rubber band, two paperclips and an old battery. Poke a hole in the center of the bottom of the can and in the center of the lid. Hold the …
Our suggestion today is a surface tension experiment, that is really a variation of the experiment with milk, food coloring and soap. The variation consists on using white glue instead of milk. You need to cover with glue a small transparent container such as a yogurt lid. Then you put some liquid food coloring on the surface. You will see that the color drops remain attraped in the glue. Then …
Science and art make a good combination, specially when working with children. Today we suggest you combine them again by making an artistic creation with a scientific background, to observe the salt water absorption process. You need cardboard (better a dark one) , glue, salt, water colors and a brush. First you make a drawing with the glue on the paper. You will get a better result if appying the …
