Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

Many scientists attempted alchemy for hundreds of years before a full understanding of metals became clear. Scholars take a penny and, through two different chemical reactions, make it appear to turn into silver and later gold. They...
