Bones and muscles

Hi dear students,

In Science we have started to learn about our body, specially we are working with our bones and muscles.

Here you have a video to watch at home. Next day I will ask some questions to you!

As the video is a bit long, I summarize the most important ideas:

• Bones are hard and they are made of calcium.
• All bones are connected by joints to form the skeleton.
• The femur is the largest bone.
• Muscles are soft and they expand and contract moving our body.
• The smallest muscle is inside our ear.
• Your bones and muscles will grow in good condition if you: eat heatlhy, do exercise and maintain a correct posture.
