One more magnet experiment – making a paper clip hover

Previously we searched for steel balls and studied magnetic lines (LISÄÄ LINKKI, KUN SE MAGNEETTI JULKAISTAAN). I wanted to return to the topic and demonstrate that magnets assert an effect on a wider area than their own size, so we played with a paper clip and made it hover. For this experiment you need: a … Continue reading One more magnet experiment – making a paper clip hover

Opening up the world of magnetism

Electricity and magnetism are interrelated phenomena named electromagnetism. Electrically charged particles create a magnetic field around them and magnets can create electricity by moving electrons around in objects near them. This phenomenon is utilised f.ex. in generators and wind turbines. In these experiments no electricity is made, but at some point we will build a … Continue reading Opening up the world of magnetism

Opening up transformation between liquids and gases

We've focused on states of matter and transformations between then for a some time now. Previous posts can be found here. We have looked at solids, liquids and gases and transformations between solids and liquids. Finally we will look at transformations between liquid and gas. I've often had daughter with me as I cook. It … Continue reading Opening up transformation between liquids and gases
