• The human skeletal system is made of 206 bones.

• It gives the body shape and support.

• It protects important organs like the brain, heart, and lungs.

• It works with muscles to help the body move.

• Bones store minerals such as calcium.

• Bone marrow inside some bones makes blood cells.

Living organisms have special characteristics that help them survive and grow. They move, even if some move very slowly; they respire to get energy; they respond to stimuli like light, sound, or touch; they grow by increasing in size; they reproduce to make more of their kind; they excrete waste from their bodies; and they need nutrition to stay alive. These seven life processes—movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition—show us that something is living.

Muscles are special body parts that help us move, stay strong, and do everyday activities. They work by tightening and relaxing, which lets you walk, run, lift things, smile, or even blink your eyes. Your muscles are connected to your bones, and when they pull on the bones, your body moves. You have many muscles all over your body—some you can control, like the ones in your arms and legs, and some work automatically, like the muscles that help you breathe. Muscles also keep your posture straight and protect your organs by giving your body shape and support.

Most plants are green this is because they contain a green pigment (colouring) called chlorophyll.

Plants use this energy to make food.
