Have you ever seen a boy who looked just like his father when he was younger? We can often tell that two people are related because they have several similar physical traits. This is because children receive half of their DNA (i.e., their genetic blueprints) from each parent. What about fingerprints – are they an inherited trait? Fingerprints are used to identify people because each person’s fingerprints are unique, but people can have similar fingerprint patterns. This… Read more

Have you ever wanted to bake the perfect pie to help warm up the cold holiday season? No matter whether it is apple, pumpkin, chocolate, pecan or pumpkin pie, every good pie needs a well-made pie crust. If the pastry crust is heavy or chewy then that can really affect how much you enjoy the pie. But how do you make a pastry crust that is light and flaky? In this scrumptious science activity, you will find out by investigating how the temperature of fat used (in dough) can affect a… Read more

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.Engineering Connection Mechanical engineers design a wide range of consumer and… Read more

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Tasty Arrangements: How to Position Food in Microwave Cooking

Science Fair Project Idea

Scientific Method

When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.… Read more
