Stage 3 – Opening Activities
Warm Up: (10 minutes)
1.
2.
What were your reactions towards the frog dissection?
Would you want to do things differently if you could?
Stage 4- Learning Plan
GUIDEDPRACTICE “WE DO” (10 mins)
 Teacher and student will create a Venn diagram noting the main differences between the frog and the
human body.
Independent Practice “YOU DO” (25 mins)
 Students will write three paragraphs noting the main differences between a frog and the human body
using detail from both what we’ve learned in class and what we learned in the lab.
 One paragraph of this will need to talk about the social impact on dissecting a frog. Students will need to
address the question “did you feel any guilt while dissecting a frog?”
LESSON FOCUS “I DO” (10 mins)
 Teacher will introduce the homework packet for the week of completing the science fair project.
GUIDED PRACTICE “WE DO” (10 mins)
 Teacher and students will review a list of potential scientific questions students could use for their science
fair project.
 Students will need to have chosen their scientific question and written down their hypothesis before
leaving class.
SCIENCE FAIR PROJECT – Steps of the scientific method
Directions: Please complete the worksheet as clearly as possible. This worksheet will help you do the steps of the
scientific method so you can be organized for your science project. Each part matches a section you need on your science
fair poster. On your poster, some of these questions (purpose and procedure especially) should be longer than there is
space here.
1.Topic:
_____________________________________________________________________________________________
2. Scientific question:
__________________________________________________________________________________
_________________________________________________________________________________________________
3.Purpose(Why did you choose the experiment that you are conducting?)
__________________________________________________________________________________________________
__________________________________________________________________________________________________
4. Hypothesis (An educated guess before the experiment begins. This one sentence answers your scientific question
above.)
__________________________________________________________________________________________________
__________________________________________________________________________________________________
What is your independent variable? __________________
What is your dependent variable?_______________________
5. Research: From your references what 5 main points (facts) did you find?
1=
2=
3=
4=
5=
6. Materials: What do you need in order to complete your research? Remember, you must come up with these materials
on your own! If you need to borrow equipment (microscope, a chemical) we will try to arrange an after school event.

7. Procedure: Write the steps would you follow to complete your experiment (directions)? These can be numbered.
8. AFTER YOUR EXPERIMENT YOU WILL COMPLETE:
1) Data( present using tables, graphs, charts, etc, as well as pictures and drawings)
2) Results/conclusions (don’t just state the results, explain why you think they occurred!)
3) Prepare for presentation (make sure your poster is clear and you know how to explain your work)
4) Know your experiment inside-out (Be able to discuss your experiment)
MAKING YOUR POSTER:




Use a trifold carboard display.
Use at least size 16 font.
Make it attractive and neat
Include pictures, drawings, or
where possible.
