Please read through the class description for a more detailed explanation.
All learners will need paper and their preferred coloring implements when there is a coloring page.
It will be easier for you if you're able to print the worksheets and coloring pages but students are welcome to create their own drawings and charts if that isn't an option. 
If your learner will be taking notes or drawing, they will need the appropriate supplies for that.
If your learner will be creating the same models as I use, they will need a glass jar, beads (mostly red and a few blue and white), water. I bought all my supplies new and spent under $10.
If your learner has another idea for creating models, they'll need whatever supplies they will be using.
If your learner wants to complete a dissection (optional), then they will need an animal heart to dissect (usually available at a butcher for $5-10 depending on what animal/size the heart is). The heart will typically be frozen so plan ahead to have time to thaw. Your student will also need dissection equipment such as a tray, knife or scalpel, scissors, tweezers or something to hold the tissue while cutting without endangering their fingers, a tray, gloves, eye protection. Please read through the parental guidance for safety warnings. 

Learners will not need to use any apps or websites beyond the standard Outschool tools.

This class includes an optional dissection. Please note that dissection involves cutting heart tissue with sharp instruments. Those sharp instruments are just as capable of cutting your learner's fingers! Please only allow your learner to do any dissecting themselves if they are already competent with sharp instruments or only allow them to do the parts that can with done with scissors. Even if your learner is quite capable, please observe them the entire time they are working with sharp instruments or raw meat and make sure they clean up properly afterwards to prevent injury or disease. 

Nothing in this class will be or is intended to be medical advice.  This is merely educational in nature and will be a surface-level overview.  Your student will not be coming out of this class knowing anything about how to diagnose or treat these conditions and we will not be discussing any personal medical questions/needs.  Students should come with general questions about the topic.
