Objective:

At the end of this mini teach students should be able to explain what blood is 
and explain the circular movement of blood going in and out of the heart.

Materials Needed:

Crayons,a paper model of the heart, glue, stethoscope, a pump with a one way 
valve, attached tubing of the correct size to snugly fit a large hand bulb, a 
diagram of the heart showing continuous circulation. 


Strategies:

Students will be given the opportunity to listen to their heart beat and to take 
their pulse rate.

Teacher will explain and describe what blood is and how it moves in a circular 
path in and out of the heart.

Students will be given a simple riddle on the functions of the blood in which 
they will be asked to guess what it is.

After students have answered the riddle, an explanation for taking their pulse 
and listening to their hearts will be given in reference to the blood 
circulating in and out of the heart. 


Evaluation:

Students will be asked to paste the heart onto the baby diagram and use their 
red crayon to trace the circular path of the blood in and out of the heart 
looking at the teachers model. 

Conclusion:

At the end of the mini teach I would like for my students to be able to explain 
what blood is and to trace the circular path of the blood going in and out of 
the heart.
