This is a unit of scripted lessons explaining the water cycle. The lesson content and learning styles are differentiated to address the students’ varied intelligences, preferred learning styles, readiness and interests.
Notations refer to the learning theories of Howard Gardner (1993) and Robert Sternberg (1985) as well as other theorists. Regarding Sternberg’s theories of interpersonal and intrapersonal learning styles, I have melded them with other theorists’ categories and refer to the styles as “small group” and solitary. I also include auditory for lessons in which students may learn from hearing.
These suggested lessons are also intended to provide limited stimuli environments as well as opportunities for full interaction with other students.For Teachers: An Introduction to a Differentiated Water Cycle Learning Unit by Jean L. Hill, FSC Graduate student
Do You Really Want to Know Where That Water Was Before It Was Poured Into Your Bathtub or Your Water Glass?
Visual, auditory, problem-solving intelligence (p.i.)
Part to whole, whole to part, visual, contextual intelligence (c.i.) p.i.
What uses water? Do plants use water?If so, what do plants do with water?
c.i., p.i., auditory, logical mathematic (l.m.)
Plants can drink water even if they do not have roots. They pull water up through their stems. The water travels to their leaves and flowers. Some of the water becomes part of the plant.
Next, the plants transpire (sweat) the excess water into the air.
3. The water in the air evaporates.
You could say that plants borrow water.
They use it and give it back.
Did you see or feel any water on the flower’s petals or leaves? Do you think some of it evaporated?
See the sun glistening on the ocean water. As the sun warms the water on the surface of the ocean, the water evaporates and rises into the sky.
Now, what happens to water after animals drink it , bathe in it, and slosh in it?
Let’s look again at the cycle of the water that the dinosaurs were sloshing in and the hippopotamus was gulping.
The water that condenses and makes your hands wet when you hold a glass of ice water in a warm room was once invisible water vapor in the air. The water that rains from the sky was once on the ground and in the oceans and rivers, and in your bathtub, the local pool, and your glass.
All the water we have on earth is all the water we have ever had, and all the water we will ever have.
It is used in a cycle!
Now, would you like a nice, cold drink of hippopotamus bath water?
Play Water Cycle Think Tac Toe
The penny experiment teaches that water molecules attract each other and stick together. This property of water molecules sticking to each other is called cohesion. The property that makes water stick to other substances is called adhesion.
The spill experiment demonstrates the same sticky property of water.
The terrarium is a miniature “earth” with the plastic acting as the outer layer of the atmosphere keeping the water in. If you cut the bottles in half then make a couple vertical slices in the bottom of the upper half of the bottle, it will slip over the bottom half of the bottle more easily. We tape the top and bottom together to prevent leaks and to keep the bottle together. To plant in the terrarium, students place some stones in the bottom, then soil, then a plant cutting. Pothos works well. They put the top half of the bottle on so the bottle looks like it did originally, but a little shorter. They water the plant through the top, then screw the cap on and promise not to take it off. They see for themselves that water is used and reused as the plant transpires, water condenses inside the terrarium, and the plant grows.
