Thinking together - culturally responsive ideas for science: Revision

If science is a way of understanding the world then we can look all around the owrld and all through time to find out how people have understood and explained the world around them in different ways.  It is not the place of modern, western science to try to show that the other ways of thinking are 'wrong'.  I hope that this page will offer ways to explore the ideas that come from Maori and Pasifika stories and technologies with science to enable a new understanding and appreciation of the knowledge that has been handed down over the years.

1. Cooking with steam.

There is a long tradition of cooking with steam in maori life.  If we look wider this idea occurs in various forms across the Pacific - umu, luau. We have pressure cookers and rice cookers in our NZ kitchens, eastern cooks use baskets over the wok to steam meat and vegetables.  So how is it that steam can cook?

Here is where a science investigation and exploration comes in.  I suggest you do some exploring about the states of water to start - matter comes in three states: solid, liquid and gas.  The states change because of changs in temperature. Think about water then - what do we call it's solid, liquid and gaseous states?  What temperature are they? How can you find out?  What do you think people in the past noticed about these states? How do people without electricity and western kitchens cook? Find an expert, in person or online, who can help you discover more about hangis or umu.  Find out as much as you can about the process of cooking in a variety of ways - fry, boil, roast, steam - compare the results using simple foods like potatoes, eggs, sauasage?  Collect data on the results - time it takes to get a cooked food, compare textures, appearance, temperatures.  Do you need different equipment to cook in different ways.  What do you like best?  What still works without electricity?  Which is faster?  How do the differnt foods cook in the differnt methods?

It would be great to have someone come and help you set up a hangi to experience the whole process - the traditions, the reasons for certain materials, why they are put together in particular ways, the customs and taboos.  All cultures have various customs around food preparation, cooking and serving.  Do these customs have a basis in science?
