1. Adaptions of Living Things: Movement Through Fluids

2. Background Features that allow a living thing to survive in its environment are called adaptations. Adaptations may be body parts, abilities and skills, or behaviours. Birds, bats, sharks, and dandelion seeds all have something in common.

3. The survival of each of these species, as well as many thousands of others, relies on its ability to move efficiently through a fluid, be it air or water. The parachute-like tufts of dandelion fruits and the helicopter –like motion of the winged fruit of maple trees, for example, are adaptations that have allowed these plants to survive.

4. The characteristic form that varies with each air and water creature has come about through countless generations of adaptations. Streamlined shape, lightweight bones, and powerful muscles are but a few of these adaptations.

8. Activity One Birds of flight!! Pictures. Discuss the features of the birds. These features, some of which allow birds to fly, are called adaptations. An adaptation can be physical or behavioural; it allows a living thing to survive in its environment.

9. What adaptations (features) allow a bird to fly? How does the bird move in flight? Characteristics birds have- wings, feathers, body shape and???

10. Other than birds, what else can move through air? Insectsarchery arrows Batsseeds Planes Hang gliders Rockets Darts Lawn darts

11. Pictures of fish, sharks, whale. Adaptations for swimming What adaptations allow this animal to swim through water? How does this animal move as it swims? Streamlined almost bullet like- shape or the water creature.

12. Other objects that travel through water. What other living things and objects can move through water? Humans Boats Surfboards Submarines Etc?

13. Make a collage of different living things that are well adapted to moving through water and air. Do the creatures that move through air have feathers? Do all creatures that move through water have a streamlined shape? Do any plants/seeds travel by air? If so, what are their shapes?

14. What are some differences between two species of birds? What so you think the reasons are for these differences? What are some differences between two species of water creatures? What do you think the reasons are for these differences? What are the main characteristics of air and water creatures that enable them to move?
