We are starting a new unit on survival. The goals for that unit are above.

This week we will be learning about natural selection, which affects all living creatures. After watching the video on this subject, what does natural selection mean to you? Please write two sentences or more in a comment here.

The following were the learning goals for this unit:

• Humans depend on living and non-living for our survival and vice-versa.
• Medicine depends on the natural world (plants).
• There have been great changes in medicine that have lowered mortality so that we live longer and healthier lives.

Please fill out this form:

One of the biggest changes in medicine was when surgery became safe enough to do in situations where someone’s life was not in immediate danger. Today, you will get to be surgeons and do a type of surgery that wouldn’t have been done in the past:

• Edheads – Virtual Knee Surgery – Total Knee Replacement
  
• Edheads – Virtual Hip Surgery – Total Hip Replacement Surgery
