Hi guys:
Here you have a cool video about our locomotor system (or muscoeskeletal) with lot of information about it. You should watch it at home this weekend.
After, try to answer these related questions in your notebook (you can look up the answers in pages 16 and 17 of Natural Science book):
1) What's muscular system made up of?
2) What's the main function of tendons?
3) How many bones do we have?
4) Whats the difference between joints and ligaments?
Enjoy!
