Accuracy and Precision Lab (with measurement and density) part of MnSTEP Activity Mini-collection
In this lab exercise, students practice correctly using measurement tools, recording data, calculating density, using significant figures, and exploring the concepts of accuracy and precision.

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.

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.

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.

How high is BIG? - using an astrolabe part of MnSTEP Activity Mini-collection
Use an astrolabe to measure the height of objects, and see seasonal changes over time.

Study of student precision using volumetric glassware part of MnSTEP Activity Mini-collection
This lab is an activity designed to demonstrate to students the importance of the proper use of lab equipment. Also to demonstrate how math can be used as a tool for analysis of data.

Statistical Analysis of Lincoln part of MnSTEP Activity Mini-collection
Students will statistically analyze data gathered in reference to the Abraham Lincoln penny.

Mineral Density: Teaching accuracy, slope, and percent error in the Earth science classroom part of MnSTEP Activity Mini-collection
This activity is a lab investigation in which students make mass/volume measurements of several samples of the same mineral to determine the mineral's density. Students graph their data and make the connection between their qualitative understanding of what density is and the mathematical/graphical representation of density.
