Science Projects – Experiments – STEM Activities

In an analysis of 6 studies including more than 35,000 kindergarten-ready children, it was found that comprehension of the world was the strongest indicator of the kid’s future academic performance. Comprehension or general knowledge of the world is a very broad category, but it basically means common sense in daily lives. It is not surprising that…

Life Cycle of Silkworm

Silkworms are native in China. They spin cocoons of fine, strong and lustrous fiber which can be used to produce raw silk. Silkworms are domesticated insects which means they cannot survive in the wild by themselves.   The practice of breeding silkworms for silk production has existed for at least 5,000 years in China. Silkworm…

Skittles Science Project (Candy)

What do you do when there is an oversupply of candies in the house, like the day after Halloween? (yeah, right.) Candy science experiment, of course! This experiment is really spectacular to watch, but the science behind is pretty complicated… actually, I haven’t found a definitive scientific explanation agreed by all authoritative scientists yet. But…

Weathervane | Weather Science

Summer is more than half way through. Soon it’ll be fall and the change in seasons is usually accompanied by curious questions about the weather.  Since autumn is often windy, one inevitable question is: Where does wind come from? This question has two meanings: a) how is wind created? and b) which direction does the wind…

Easy Science Experiment: Gravity And Magnetism Activity

Normally, paper clips do not fly into a hand that hovers over them. That is because the gravitational force pulls the paper clips toward the Earth. In the experiment, you will use a strong magnet to make the paper clips come upward into your hands. It’s almost like the paper clips can defy gravity. But…

Evaporation —> Distillation | Water Science

What do bottled water and cloud have in common? They both involve a process called evaporation. Evaporation is an important step in the water cycle. Warm water evaporates and turns into vapor. In bottled water factories, water is boiled and vapors are collected to make the product. In nature, drops of vapor gather to form clouds…

What Makes Ice Melt Faster? Salt Melts Ice Experiment

Why do people put salt in snow? That’s because salt can make ice melt faster. Ice melts at a specific temperature called the melting point. Salt makes snow melt faster by changing ice’s melting point. Here is an experiment showing how salt achieves that. Using salt, you can pick up a piece of ice with…

Fun Math Games – Learning Shapes And Patterns Activities

Patterning is fundamental to mathematics because all math are virtually patterns and structures. Mathematical relations and transformations result in patterns and abstraction. It is therefore critical to children’s development of mathematical reasoning. The integration of patterning in children’s early learning can promote such development. There are many types of patterning: written symbols (e.g. ABCABCABC…), numerical (e.g. 1,…
