Safety Notes

As a Let’s Talk Science volunteer, safety must be foremost in our minds during all activities. As STEM role models, volunteers must always also model safe science practices.

Always keep in mind the following precautions:

  • Emphasize and demonstrate appropriate safety procedures throughout the presentation.
  • Be professional but have fun.
  • Keep workspaces clean to avoid tripping hazards.
  • Allergens should have been checked before reserving the kit (e.g. allergies to latex).

What To Do

Today we’re going to model how blood flows through your heart – you are going to be the blood and a model of the heart will be on the floor.

Ask the teacher to distribute the colouring pages and a red and blue crayon to each student.

You could also have the teacher make the model on the floor at this point. She/he needs to make 4 large boxes – large enough for a student to stand in. The two on her/his right should be done using blue tape with the one closest to her/him being slightly smaller than the one further away. The two on her/his left should be red and again the one closest to her/his feet smaller than the one further away. He/she could also add in the inferior vena cava (blue), aorta (red), pulmonary vein (blue), pulmonary artery (red) as in the photo. The teacher can also leave red felt pieces in the lung area. Before we do this, let’s use this colouring sheet to follow the flow of blood through the heart. Then we’ll model it with us being the blood and chambers of the heart.

Ask the students to guide the teacher (without looking at their paper if they can) to lay out the names of each part on the floor using the word cards. Have the teacher distribute a blue piece of felt to each student and then one at a time each student can go through the heart flowing as blood would, saying each part as they go through it, and exchanging their blue ribbon for red at the lungs, etc.

We usually do this activity along with the digestive system activity as both are about 20-30 minutes long. See Related Activities below.
