1. Five Types of Bone Fractures

The five types of bone fracture are:

(i) “Greenstick” in which the break goes partly through the bone.

(ii) The second type of bone fracture is “compound” in which the bone breaks through the skin.

(iii) The third type is “comminuted ” in which the bone is shattered into several pieces.

(iv) The fourth is “multiple” in which the bone breaks in more than one place.

(v) The fifth is “simple” in which the bone is broken all the way through, in one place but the skin is not torn.

2. What is Photosynthesis?

Photosynthesis is the name of the process by which plants produce food. All the plant needs to make food is sunlight, water, and air. With all these ingredients the plant makes sugars. Later the plant changes the sugar into starch, protein, and fat. These are exactly the food that the human body needs.

3. What is Hydroponics?

You don’t need a lot of ground to grow plants. You can grow them without soil. They can grow on a mat in a large building or even in spacecraft.

4. What are Cactuses?

Cactuses are thick pulpy plants that grow on the top layer of soil in the desert. Its long roots, just below the surface soaks up the rain quickly. It also does not need much water to grow.

5. Sap

Sap comes from trees. You can make gum, syrup, and turpentine from tree sap. The “Sapodilla” gives the gum. The “Maple tree” gives syrup for pancakes, and the “Pine” tree gives turpentine.

6. Experiment with celery in water and without water

The celery in water stayed crisp and alive. The celery without water withered and died.

7. Experiment growing Devil Ivy in water and in soil.

Both of my plants seemed to be healthy even though they have not rooted. With water and sunlight they should root. I will keep them watered and see that they get sunlight until they root.

8. Experiment with plant leaves covered with Vaseline

a. The stems of the leaves covered with Vaseline are turning yellow and the leaves are limp.

b. The other leaves that were not covered with Vaseline seem green and healthy.

9. The tallest trees in the world.

The Redwood, one type of sequoia, is the tallest tree in the world. They are as high as a 30-story building. It grows in the Northern California.

The other sequoia grows near the Sierra Nevada and it has a thick trunk. They both have been known to survive forest fires because of their thick bark.

They live to be about 300 to 3,000 years old.

10. Hitchhiker Seeds

(a) "Hitchhiker seeds" have tiny hairy hooks that hook to the fur of animals that carry them away to some distance before they fall off to start growing.

(b) " Flier seeds" are carried by the wind and they settle on

the ground to grow.
