Investigate Chemical Changes - What are some signs of chemical change? part of MnSTEP Activity Mini-collection
This activity is a classroom lab activity that demonstrates chemical change in a dramatic way using a few inexpensive, easily obtainable materials.

Mystery Powders: An Introduction to Physical and Chemical Properties part of MnSTEP Activity Mini-collection
In this classroom guided inquiry lesson, students will complete a serious of tests using five different mystery powders. Student will develop hypotheses, make observations, and draw conclusions about what each powder is and the physical and chemical reactions that occur when heat, water, iodine, and vinegar are added to each substance.

Bridges, Building and Breaking part of MnSTEP Activity Mini-collection
This activity s a student project to construct and test the load bearing capacity of a scale model bridge from toothpicks.

Save an Animal Board Game - Impact of Human Activity or Natural Disasters part of MnSTEP Activity Mini-collection
This student activity engages the students' thinking by listening to a story, brainstorming ideas in small groups about how human activity or natural disasters could possibly impact an animal's environment, and then reinforcing that thinking using a board game called Save an Animal.

Ice Cream Model -- How Glaciers Formed the Minnesota Landscape part of MnSTEP Activity Mini-collection
This activity is a teacher demonstration of an ice cream model representing glacier movement across Minnesota. Teacher/student questions and discussion should be encouraged during the demonstration.

Designing an experiment to test the rate of photosynthesis part of MnSTEP Activity Mini-collection
This activity is a lab where students design an experiment to test the rate of photosynthesis. Students will analyze data,write a report using the scientific method, and apply results to current environmental issues.

Do all types of lights follow Ohm's Law? part of MnSTEP Activity Mini-collection
In this physics lab students will investigate whether Ohm's Law applies to common electric devices (incandescent light bulbs and LEDs).

Investigating Acid Rain: The Affect of Acid on Seed Germination part of MnSTEP Activity Mini-collection
This activity is a self-created lab investigation where students gather data on acid and its affects on seed germination.

Chromatography: Who Wrote the Note? part of MnSTEP Activity Mini-collection
This lesson has students solving the mystery of a note by conducting chromatography. They will test different washable markers and see that different marker colors are made up of various pigments. They will compare and contrast the note chromatography with other chromatography results from a variety of markers.

Building A Protein part of MnSTEP Activity Mini-collection
This is a hands-on activity to assess the students understanding of peptide and disulfide bonds formed during protein synthesis. Students demonstrate the process of dehydration synthesis by combining amino acids through peptide bonds creating molecules of water, and one protein amino acid strand. It can also be used to assess students understanding of the process of translation.
