Math is a subject that very quickly requires abstract thinking. We turn a number of objects (like three beads) into the number 3 and teach our kids that they mean the same quantity. Then we teach our kids that we can add and subtract, multiply and divide these numbers and do all sorts of things … Continue reading Opening up the world of multiplication with cups and beads

Opening up the world of decay and rot
I've often commented on not leaving trash outside. I have explained that trash is dangerous to animals and birds. We have taken a plastic bag with us as we go for a walk and have picked up trash left by others. This is especially needed after New Year to clean trash created by fireworks and … Continue reading Opening up the world of decay and rot
Colouring flowers – opening up the world of capillary action
Lately we have looked at how water behaves and even approached the topic of capillary action here. However, I really like this experiment explained here because the results are so clearly visible. I've only gotten it to work with blue colour. I am a bit unsure as to why, but I think it is most … Continue reading Colouring flowers – opening up the world of capillary action
Between liquids and solids – the magic mud
Lately we have focused on states of matter in our experiments. We have studied solids (here), liquids (here and here) and gases (here) as well as transformations between these states of matter (here and here). One substance we found that was in between liquids and solids was magic mud. Magic mud is created when you … Continue reading Between liquids and solids – the magic mud
Learning coding with Swift Playgrounds
Coding is one of the skills I have wanted to learn and wanted to teach my daughters. I occasionally find a new way to do this. Swift playgrounds is one of these ways. I had it for months on my iPad before I ever tried it. Luckily I finally did. Swift Playgrounds has three different … Continue reading Learning coding with Swift Playgrounds
Opening up the world of solar power
I have wanted to experiment with solar power for a while now, but Finland is not the best place for these experiments. Most of the year the sun shines here at such an angle through the atmosphere that there isn't enough of sun power for good experimentation. However, we do get some really warm and … Continue reading Opening up the world of solar power
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
Opening up the transformation from solid to liquid and back
This spring and summer we have looked at states of matter. We looked at solids here, liquids here and here and gases here and previously also here. This is only a part of the story so to speak. We have also conducted several experiments on the transformation between one state of matter and another. We … Continue reading Opening up the transformation from solid to liquid and back
Opening up the world of states of matter – gases
There are many states of matter. Previously we have covered solids (here) and liquids (here and here). This time we will focus on gases. Gas is a state of matter in which the molecules have so much energy to move that forces holding the molecules together is small or zero. This causes the distance between … Continue reading Opening up the world of states of matter – gases
Opening up the world of liquids – part 2
In the first part (here) of liquids we looked at buoyancy, surface tension, density and viscosity. We continued with these concepts even further. I like to do several experiments on the same topics spread over time. The reason for this is the way our brains work. If we hear a concept only once, and even … Continue reading Opening up the world of liquids – part 2
