Simple Science: Coke-Mentos Explosion

This is a very easy experiment and one that all kids love. It’s messy so best to do it outside. There are also lots of variations you can test out: Diet versus normal soft drink Coke versus other soft drinks Mentos versus other sweets Hint: for the biggest explosion use diet soft drink and fruit Mentos.Continue reading “Simple Science: Coke-Mentos Explosion”

Science Experiments: DIY Volcano

Science is not only an important subject for kids to learn but it can also be extremely fun for the family to learn together – especially when you’re working with experiments of an explosive nature… One of the simplest science experiments that kids love to do is the volcano science experiment. Here’s how you can do it atContinue reading “Science Experiments: DIY Volcano”

Simple Science: 3 Cool Bubble Experiments

Too awesome! We gotta try this – especially the neon one since the boys are so into “glow in the dark” stuff these days… There’s not a lot about the science behind it on the video, so here are the links if you want to look them up… How does highlighter ink make the bubbles glowContinue reading “Simple Science: 3 Cool Bubble Experiments”

Simple Science: How Plants Absorb Water and Nutrients

We had excess food dye left over from our Advanced Potion Making Class so we decided to try the coloured-water absorption experiment with cabbage leaves. You can use other plants, like celery or flowers, but the effect is clearest when you use a light coloured plant, like chinese cabbage or white daisies. We didn’t have easy access toContinue reading “Simple Science: How Plants Absorb Water and Nutrients”

Simple Science: Magic Cornflour Mud, Oobleck, and Non-Newtonian Fluids

Borrowed another idea from G2’s class yesterday… Magic Cornflour Mud The recipe I borrowed from Scientific American: 1 1/2 cup cornstarch 1 cup cold water Food colouring The intention was to make brown mud, but what d’ya know… I bought two bottles of blue food colouring instead of one blue and one yellow. Since I only hadContinue reading “Simple Science: Magic Cornflour Mud, Oobleck, and Non-Newtonian Fluids”

Simple Science: Dilatant Materials – Silly Putty and Melting Martians

The boys received Melting Martians for Christmas… It is a surprisingly simple idea but it has kept the boys entertained for a lot longer than I would have expected. It’s also neater and cleaner than Play Doh – I wonder if we can get more of this stuff from somewhere…? Here’s how it works: You build a MartianContinue reading “Simple Science: Dilatant Materials – Silly Putty and Melting Martians”

Simple Science: pH Indicators, Acids and Bases with Red Cabbage

Any experiment with colour is always a sure winner. If it has changing colours, even better… So when I saw this pH experiment kit, I couldn’t resist. This is another experiment by Denjiro that I bought from Japan. Like our Solar Car, the instructions were entirely in Japanese but between the pictures and what I could recall fromContinue reading “Simple Science: pH Indicators, Acids and Bases with Red Cabbage”

Simple Science: Solar Powered Car

When I was a kid, I had a school excursion to some science exhibition where they taught us about renewable and non-renewable energy sources. They had a model “energy saver” house that ran almost entirely on renewable energy sources. It left quite an impression on me and it made me a whole lot more conscious aboutContinue reading “Simple Science: Solar Powered Car”

Simple Science: Awesome Coloured Milk Experiment!

There’s a really cool experiment on Science Alert that I tried with the boys recently. It’s so easy and so visually impressive that it’s almost criminal to sit this one out. It’s not often that you come across an experiment that makes such an impact and doesn’t require any fancy materials or equipment… Here’s what you need:Continue reading “Simple Science: Awesome Coloured Milk Experiment!”

Simple Science Activity: Lava Lamps

G2 made a lava lamp at school and got to bring it home… He had so much fun with it that he wanted to play with it at home again… Make Your Own Lava Lamp This is really a very easy experiment to do at home. All you need is: an empty bottle vegetable oil waterContinue reading “Simple Science Activity: Lava Lamps”
