Our next science unit is the respiratory and circulatory systems. As part of this, we have a 'goldfish lab'. It involves looking at live goldfish under the microscope! You take the goldfish out of the water and lay them under a cotton pad for a few minutes to see their blood flow. Curious, I asked my teacher what happens to the goldfish afterwards and she said that 'there aren't usually many left'. She seems pretty set on doing it. What should I do? I couldn't come back home to my goldfish knowing that I just helped in the slaughter and torture of another? Thanks!
