Surface Microbes and Microbial Diversity

Science Area: Biology/Microbiology
Grade Level: High School/College
Abstract: Microbes are found on almost every physical surface of every size, in every place, under every condition. The ability of a condition, such as surface type, to support microbial growth can be predicted by the total number of microbial colonies and the number of different kinds (or species) of microbial colonies that are present. The more varied the types and numbers of microbes, the greater the chance that some will survive if the conditions change. Microbial diversity is an indication of the ability of a particular condition, such as surface type, to support microbial growth. A biodiversity index (D) describes the amount of species diversity.

Grade Level: Elementary/Middle School
Abstract:With a national movement to emphasize STEM and STEM careers, it is important that all students receive a strong background in the concepts of STEM. To assist teachers, science, math, and other curricula must be aligned with the core principles to develop the skill set needed by future generations. These principles will be the foundation future generations need to support the core beliefs they will use in a global marketplace. This document reviews those principles and beliefs with support from 3 STC Program™ units: Balancing and Weighing, Motion and Design, and Experimenting with Forces and Motion.

Engineering: Forces and Motion

Science Area: Physical Science
Grade Level: Middle/High School (Grades 6-10)
Abstract:Secondary students will build a mousetrap car and investigate its motion. They will design an experiment to measure the speed of the car as it moves after the trap is released. Students will also identify the forces acting on the car and describe how these forces affect the car's motion.

Engineering: Electric Circuits

Science Area: Physical Science
Grade Level: Middle/High School (Grades 6-10)
Abstract: In your bedroom, can you have one light on and another light off at the same time? Can you turn off the lights in a room and still watch TV? How do you turn on a ceiling light in a room? What kinds of electrical connections make these things possible? In this lesson, secondary students will explore how to connect batteries to light bulbs so that the lights in the circuits can be turned on and off independently of one another. This lesson will help students build a model of what their home's electrical system may be like.
