Evolution, Natural Selection and Speciation part of Examples
In this out of class tutorial, students explore several examples of natural selection and speciation.

Translation simulation part of Examples
This module introduces students to the basics behind translation of a messenger RNA sequence into protein. In addition to text and movies, there are interactive shockwave animations that allow students to move ribosomes and tRNAs to perform translation.

Blue Skies & Sunsets part of Examples
This conceptual model explains why skies are blue and sunsets are red.

Balanced Forces part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.

An Introduction to and Investigation on Keystone Species part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a project in which students research keystone species and report on specific species to the class.

Best Edible Model of a Cell Contest part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is designed to help students understand the structures and functions of the cell by building a model. The students must also do an oral presentation explaining their model to the class.

String Scientific Notation/Metric System Demonstration part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Short demonstration on scientific notation by asking students to place numbers on a number line using string and notecards.

Planets Made Real - Creating Size and Distance Scale of Planets in the Student's Community part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a classroom investigation where the students create, in size and distance, a solar system model in proportion to a selected sphere representing the earth.

Investigation of Newtonian Forces on Plate Tectonics part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This model-making activity gives students an opportunity visualize Newtonian forces acting on a single point as well as combined forces acting to produce synclines and anticlines in Earth's crust. Students will analyze models to interpret findings of plate movements.

Tracking the Sun: Observing the Path of the Sun Throughout the Year part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
As an on-going project, students note the position of the sun by mapping a shadow on the classroom floor. They learn about the earth's tilt and the effect of the sun's light on our seasons.
