M & M Decay part of Rates and Time:Teaching Activities
This is a simulation of radioactive decay which illustrates what a half-life is and explains some of the challenges involved with radiometric dating. Pennies or other cheap coins can be substituted for M&Ms if ...

Review for interdisiplinary science course (stream ecology, watersheds) part of Complex Systems:Teaching Activities
This is a large-scale participatory activity used to prompt students to review what they have learned and to think actively and cooperatively about the connections between the systems we have discussed prior to the ...

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.

Projectile Motion and Gravity part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is a mini lab where students see the effects of gravity on objects falling from a resting state and objects projected out from the same level.

What sizes are the planets and how do they move around the sun? part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This is an activity to help students understand the abstract concept about how planets move around the sun and their relative size compared with other planets in the solar system.

Moon Phases Box part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This activity is an observation opportunity for students to view the phases of the moon and learn that the juxtoposition of the Earth and moon dictates the appearance of the moon in the sky.

Sinking Water: A Connection With Glaciers, Ocean Currents and Weather Patterns part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
This lesson has activities where students will learn about buoyancy and explore how hot water rises and cold water sinks. As an extension and real-life application, students will see that glacial run-off is occurring at a rapid pace and the cold glacial water could potentially change ocean currents thus influencing global climates.

Valence Electrons and Trends in the Periodic Table part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students will fill in a blank periodic table for elements 1-20 using electron-dot models. As a visual tool students should see several periodic trends.

Watersheds Urban and Rural part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Students build a model of a watershed, apply water to the model, and explore what happens when elements of the watershed are changed.
