What goes up must come down – it’s the law! This is Sandra Tsing Loh with the Loh Down on Science, saying – the law of GRAVITY! Gravity keeps us grounded on Earth and keeps us orbiting the Sun. It’s even powerful enough to pull GIGANTIC galaxies toward each other.

Are children’s toys making your head spin? This is Sandra Tsing Loh with the Loh Down on Science. The centrifuge is an essential lab tool. It’s like a really powerful salad spinner. It can separate fluids into layers based on their density. Centrifuges are critical for diagnosing diseases like malaria.

Is the key to finding dark matter. . . in your fridge? This is Sandra Tsing Loh with the Loh Down on Science. Water freezes because impurities act as “seeds” for ice crystals to grow. But, if you put PURE water in the freezer, it can stay liquid – even

It’s a bird! It’s a plane! It’s… an ion-plane? This is Sandra Tsing Loh with the Loh Down on Science. Aircraft fly using thrust from a power source to generate lift with their wings. Usually, that power source is a gas guzzling engine, or a noisy propeller. City dwellers pay

Hate crowds? Need your “personal space?” Negatively charged electrons do too! This is Sandra Tsing Loh with the Loh Down on Science. To understand electrons, scientists have developed a special technique called density functional theory – D-F-T for short. D-F-T is used to predict how electron crowds move in an

A scientific storm is brewing … about the speed of rain. This is Sandra Tsing Loh with the Loh Down on Science, saying: According to physics, everything that falls has a terminal velocity. Apples, rain, people. Terminal velocity is a steady speed, where gravity and air resistance balance out. For
