Does All Chocolate Sink?

In Class 5 we have been doing some fabulous Science this week! Following our water disasters topic we have been looking at what makes something ‘buoyant’ and why. We tested various chocolate bars and sweets by dropping them in water to see if they would float or sink. Our findings show that not all chocolate sinks! This is due to the amount of air inside the chocolate which effects its weight. Consequently, if an objects weight is equal to or less than the upthrust from the water, the object will float.

Can you guess which type of chocolate floats?
