Grade 11 Biology – Animals: Structure and Function

1. Grade 11 Biology – Animals: Structure and Function Monika, Mike & Emily

2. Unit Plan

3. Misconceptions Relating to structures of the body and nutrition

4. Young people can’t get heart attacks • While the risk of heart attack rises with age, teens and young adults can have heart attacks. • Risk factors that are controlled early in life make it less likely to persist later in life • The lesson is that just because someone is not “old” that does not mean that symptoms such as chest pain and shortness of breath are not signs of a heart attack.

5. If one of my organs fail I can just get a transplant. • The waiting lists to receive transplants are very long. • Depending on your age and overall health you may not receive one. • The best organs are the ones you already have. • New ones might not be complimentary to your body

6. You can only get diabetes if you eat too much sugar • Type 1 diabetes is caused by genetics and unknown factors that trigger the onset of the disease. • Type 2 diabetes is caused by genetics and lifestyle factors. Being overweight does increase your risk for developing type 2 diabetes, and a diet high in calories, whether from sugar or from fat, can contribute to weight gain. • Eating a healthy meal plan and regular exercise are recommended to manage your weight.

7. 0g of fat means that the food/drink is healthy • Not necessarily. • A nutrition label may have 0g of fat on it but have an excess amount of calories. • If you consume an excess amount of calories it will turn into fat.

8. Connections to other chapters • Animals: Structure and Function • The digestive system- disorders of the accessory organs and diabetes • The digestive system- chemical digestion and absorption • The digestive system and cardiovascular system and their disorders. Other Chapters • Genetic processes – understanding inheritance • Introducing evolution- artificial selection and food crops • Genetic Processes- importance of meiosis and genetic disorders

9. Dry Lab: Cardio-Respiratory Investigation • Since this is an introductory activity, make sure you stress the connections between the previous topics and new topics

10. Wet Lab: Rat Dissection • Some things to remember when teaching dissections: • Understand and communicate the value of dissections • Be able to provide alternatives for students who are uncomfortable • Have proper equipment and address any allergies (i.e. latex) • Ensure that you only have exactly as much equipment out as you need • Encourage a clean and neat dissection environment so that specimen can be used later…for a bell ringer perhaps • Allow students to circulate and see one another’s dissections • Some specimen may have better organ systems than others

11. General Dissection Rules • #1 RULE: RESPECT THE RAT • Don’t cut more than is necessary • Reminder: Wear your gloves! • You are using SHARP instruments, be careful! • Carry with blade down • When cutting with scissors, angle slightly up so you don’t cut the other organs • If you have ANY questions…ASK!!!
