Here's a selection from elements of activities designed for primary students: Female dolphins, seven-year-old Pinky and 32-year-old Jessie are used as live exhibits to explain to youngsters that they use their fins for balance and use an up and down motion to travel through the water, unlike fish, and use their tails for acceleration and as a means of reducing body heat. They show their 90-100 teeth and demonstrate how they breathe and sing through their air holes. Dolphins can use their eyes to see well in water and have sensitive ears placed just behind their eyes. They use their colour for protection and live for 30 to 40 years. In the giant panda habitat, students observe An An and Jia Jia in their environment as well as entering the bamboo classroom for a series of workshops. These include a 'Save the Giant Panda' game in which students have a limited time to save the panda emphasising the fact that unless something is done to save their habitat and lifestyle, their time is running out. In the butterfly house students go behind the scenes to have the life cycle of a butterfly explained using models and puppets. They can touch a Great Mormon caterpillar that has no hair and see how metamorphosis works in action using a wonderfully innovative glove puppet. Simple and direct instruction shows how butterflies feed from flowers, the lesson using a wooden flower with a hole drilled in the middle and a party blower ... best not to ask! Plant nursery students are shown how plants, such as mint, are planted and transplanted. The process and reasons for doing so are explained first in the classroom and then following practical demonstrations the students try for themselves. They are shown how to take care of their plant and are then allowed to take it home as homework.
