Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

students identify and explore the connection between math and the bones of the human body. Students collect data about bones from their classmates and from adults, apply formulas that relate this data to a person's height, and organize...

Students explore the concept of the golden ratio in nature and architectural design. They discuss examples such as petals on a sunflower and the Parthenon. In small groups they take turns measuring their body parts to find a golden ratio.

Students construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using growth...

Fe, phi, fo, fum. This activity leads pairs to find the ratio of consecutive terms of the Fibonacci sequence. The pairs find that the Fibonacci sequence can be found in many places. A discussion with the class shows that the ratios...

Students explore technology by completing a worksheet in class. In this common machinery instructional activity, students define the different designs that make simple machines work such as wheels, pulleys and gears. Students utilize...
