When carbon dioxide in the atmosphere dissolves into raindrops, it causes the rain to become a natural acid. It can dissolve and erode rocks: it’s acid rain. Here’s an experiment to see how chemical erosion works.

The CARIM project, funded by MBIE is researching the decrease in pH in NZ’s coastal waters and its effect on marine life.

Acids and bases are important chemistry concepts that kids can enjoying learning about as they make their own sherbet to take home.

Sit back, relax and let the carbon dioxide from a chemical reaction blow up your balloons for you.

Suzy risks putting her foot in her mouth as she investigates what causes cavities in our teeth.

Dr Michelle Dickinson will cover in this episode the concepts around climate change, how we measure it and how it's different than just weather, carry out a hands-on experiment and talk about ice cores with Tim Naish from the Victoria University of Wellington.

Te Papa conservator Rangi Te Kanawa uses her knowledge of traditional dyeing practices, science, and scientific experimentation to preserve fibres in textiles that have been dyed using iron-tannate black dyes.

Three fun activities involving eggs.

Erosion is going on all day, all the time. It’s happening right now!
