Do Now 1.What was your overall take away after completing the frog dissection on Friday? 2.What are you left wondering after the dissection? 3.What was your science fair project last year? Did you have fun with it? Did you like participating in the activity?
Announcements Homework packet Science fair project due January 23 rd. You’ll get this in a little bit but not quite yet! Late homework packets due this Friday! Rewritten essays due on Friday as well!
Agenda Comparing/contrasting frogs and human body Three paragraphs Quick explanation of the science fair sheet
Comparing Basic organs are shared between frogs and humans. Lungs, kidneys, stomach, heart, brain, liver, small and large intestines, etc. Skin Similar body shape (able to easily identify limbs, head, torso etc).
Contrasting Reproductive organs are less complex. Rib cage or diaphragm? Frog hearts are three chambered compared to our four chambered heart. What about the frogs teeth and tongue? What differences were there between the frogs hind legs compared to its front legs? Is this the same as a human? What advantages are there to this? What adaptations permit the frog to live on land and in water? How are these adaptations different from a human? (Be specific) 2. The frog's sense organs are located on top of the head. How does this help the frog when it is in water?
Three paragraphs: 20 mins 1.Differences between the frog and human body. 1.This should extend beyond the obvious physical differences and should talk about the advantages. 2.Similarities between the frog and human body 3.Social impact on dissecting a frog. 1.Students will need to address the question “did you feel any guilt while dissecting a frog?” Explain why or why not.
Science fair explained We’re doing it as a homework packet. It is due in class by the 23 rd. Every night you’ll have part of the project due. You’ll also have class time daily to work on this. This does not mean that you DON’T do your homework! You wont get enough time to complete it in its entirety.
What is a Scientific Question? A scientific question only tests one thing. A scientific question can only have one thing that is changing. This is called the independent variable. A scientific question has an independent variable and a dependant variable. THE QUESTION SHOULD ONLY TEST ONE THING! Has to be TESTABLE and OPINION-FREE
