WALT: conduct a science experiment to Learn about how a heart pumps blood through the heart and the body.
What Do i already know about the heart?
your heart is about the same size as a closed fist it is a strong muscle. Your heart just sits in the left of the middle of your chest.Your heart never stops working your heart beats slowly as you sleep. When you wake up and start moving it beats faster your heart is hollow which means it has empty spaces. The spaces fill up with blood. There are two sides of your heart,the left side and the right side your heart pumps blood. You can feel your heart beating in the blood vessels your heart usually beats about 90 times a minute. And the heart has 4 chambers
What do I need to conduct this experiment?
Jars (3) | Straws (2) |
Tape | Balloons |
Water | Scissors |
Red Dye |
What do I want to find out?
I want to find out how the blood processes through the heart and how the heart connects to the vanes. And how the heart functions. And How the heart pumps the blood through the body.
Method: I will take to complete this experiment
Add half a cup of water to the jar and add your red diy
Cut the balloon halfway at the bottom and then the other half you put over the jar and make sure its tight
Make to little holes and put the 2 straws into the small hole
Put the 2 cups beside you and then put pressure in the middle of the balloon
What do I predict will happen?
What actually happened? explanation : it went terrible and so annoying because whenever we poked the holes in the middle of the jar on the balloons it pops the whole thing.2 because whenever we put pressure in the middle it just doesn't go up into the straw and into the cup and then pop.
