The same basic rule applies to building a cubby as building a house - measure it three times, build it once.

How do you design a meal that meets certain criteria? This program looks at the role recipes, ingredients, utensils and culinary flair all play when it comes to preparing food. We follow the methodical steps taken to make a chocolate cake and demonstrate the correct use of cooking utensils.

Can we stop wasting food scraps, have a green thumb and keep worms happy and healthy all at the same time? This program shows that the answer is clearly "yes"! One of nature's perfect ecosystems is explored in this program as children set about building the ideal worm farm.
