INQUIRY DESIGN AND DEVELOPMENT That's the Question!

Starting with the different analyses, organize your information and prepare a partial conclusion to know more about the different blood types and their Rh factor.

1. Answer the following questions in your notebook:a) Based on your results, what type of blood is more common in your community or neighborhood?b) How difficult is it to receive a blood transfusion if you have the least common blood type? c) How would you design a method to find the proportion of the different types in a blood bank? d) How would you keep control in a blood bank to know the number of bags used versus the total number in the bank?

2. Speak to different students about a strategy to predict a person's blood type and Rh factor. After the discussion, you can get a hypothesis like the following:"Type B blood with Rh factor is the least frequent so it is more difficult to have this blood type for transfusions."

3. In assembly, select one of the following problems, solve it, and demonstrate the hypothesis. Problem 1: If a person needs a blood transfusion, what is the probability of receiving it in your community?Problem 2: If there is no sufficient blood in a blood bank, what alternatives can you recommend for promoting the culture of blood donation?

To solve the given problems, use the following strategies:

Strategy 1: Use probability and link all the obtained data. Consider that the person will need to make an immediate donation, and the difficulties and risks.

Strategy 2: In a blood bank, you need to have exact information about the blood types so you can use them when necessary. To do this, you need to use probability to show the data.
