Conservation of Mass Gum Lab part of MnSTEP Activity Mini-collection
Students develop and conduct an experiment using the law of conservation of mass to determine whether or not gum should be considered food. Students will compare the mass swallowed for sugar and sugar-free gum. This could be used to discuss solubility.

Investigating Osmosis using water and gummy bears part of MnSTEP Activity Mini-collection
This activity is a classroom lab where the students gather data on the affect water has on gummy bear candies and develops an experiment based on a new question regarding a not plain water solution. Students will perform calculations and graph their results.

Predatory-Prey Relationships: The Fox and the Rabbit game part of MnSTEP Activity Mini-collection
This activity is a simulation that illustrates how population sizes are affected by predator-prey relationships and competitive interactions among prey.

A Comparative Approach To Animal Dissections (A Phylogenic Study) part of MnSTEP Activity Mini-collection
In this biology inquiry lab, students study evolutionary relationships by making observations of preserved animal specimens, developing a question, then investigating by dissecting the specimens provided.

Introduction to Human Tissues: How are Tissues Classified? part of MnSTEP Activity Mini-collection
In this inquiry investigation, students will observe unknown tissue samples and draw them in their science notebooks. They will work in groups to present and defend a classification scheme for the unknown tissues to the class, and then use textbooks as a reference to compare their scheme to the accepted classification system.

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.

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.

HYDROGEN-OXYGEN ROCKETS part of MnSTEP Activity Mini-collection
During this activity students build a plastic pipette rocket. The first concept will to learn how igniting varying mixtures of hydrogen and oxygen will affect how far the rocket will fly. Second students will observe and manipulate variables to better understand the fundamental chemistry concepts: principles of combustion reactions, kinetics, stoichiometry, gas mixtures, rocketry, and different types of chemical reactions. Finally, students will assess their own understanding of these chemistry concepts by investigating how NASA scientists launch real rockets into space. One follow-up activity would be to investigate and collect data on a launching a heavier object at the school football field.
