Investigating Natural Selection: Observing Stabilizing and Directional Selection through Graphical Analysis of Population Samples. part of MnSTEP Activity Mini-collection
This lab activity demonstrates the difference between stabilizing and directional natural selection using two separate populations of sunflower seeds.

Investigating Ordering Planets: Math Connections and Number Sense in Science part of MnSTEP Activity Mini-collection
This set of activities is designed to help students develop an understanding of scale/distance and ordering the planets from the sun, understanding Earth's position in the solar system, and developing new ways of determining "order."

The physics and engineering of a trebuchet part of MnSTEP Activity Mini-collection
This activity is a hands on investigation in which students will construct, and launch a trebuchet.

Classroom Phenology: Using the Environment as a Source of Data and Observations part of MnSTEP Activity Mini-collection
This activity is a classroom and schoolyard investigation where students collect daily temperature and precipitation readings, weather observations, and weekly phenology reports in a phenology binder and in nature journals. Students then analyze this data and compare to recorded values in the Weatherguide calendar.

Measuring and Graphing Toy Water Animal Growth part of MnSTEP Activity Mini-collection
This activity is an guided inquiry based lesson where students measure and graph data on a two-coordinate graph the growth of a toy animal submerged in water over a period of time.

Trends in Alkane Boiling Points part of MnSTEP Activity Mini-collection
This activity is an investigation into the relationship between alkane length and boiling points. Students develop a mathematical model of this relationship and use it to make predictions and error analysis.

Investigating Variables : Passengers Supported by Lifeboats part of MnSTEP Activity Mini-collection
Short description This activity is a lab investigation where students develop an investigable inquiry question, construct a fleet of boats, collect data about how many passengers (pennies) each will hold before sinking, interpret their findings, and will share methods and results during a poster session.

Metric Converstion at a Glance part of MnSTEP Activity Mini-collection
Metric Conversion at a Glance is an easy way to teach students how to convert one metric measurement into another without the use of fractions. It works for one, two and three dimensions – length, area and volume.

Effectiveness of MN dams in water retention/ Efectividad de represas en Minnesota con respecto a la retencion de agua part of MnSTEP Activity Mini-collection
This activity is a field trip investigation where students gather stream flow, volume, depth & height (area) data on Ramsey County dams (Keller and Round lake), interpret their findings and make in-depth observations in order to assess the effectiveness of dams through the season and estimate the life-spam of the dams in years.
