In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.

In this engineering design activity, learners will design, test, and build a “haunting machine” to solve a Sherlockian mystery.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
