Want to give your students a visual way to see how bloodtypes are received or donated? This is a great activity to use anytime of the year.
This form of the activity I have set up to do on Halloween or around that time of the year in school. It also works well in the genetics unit as blood type is discussed as a genetic trait.
Another form of this activity is sold for Winter (around Valetine's Day - called "You're Just My Type").This can be done as a demonstration or as a small-group lab. Set-up instructions are included.
