Investigating Starch in Foods part of MnSTEP Activity Mini-collection
This activity is a classroom experiment where students gather data on which foods contain starch. They use observation and develop their own hypothesis to create a question they would like to discover about starches.

What sizes are the planets and how do they move around the sun? part of MnSTEP Activity Mini-collection

Investigating Wolf Behavior part of MnSTEP Activity Mini-collection
This activity is a classroom investigation of wolf behavior where students use observational evidence to identify and describe wolf pack structure.

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.

Walking on Water--How Do Water Striders Do It? part of MnSTEP Activity Mini-collection
This activity provides students with a first look at water tension and its role in the life of a water strider.

Exploring molecular movement: does temperature matter? part of MnSTEP Activity Mini-collection
This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

Force and Motion: Gravity and Wind Resistance part of MnSTEP Activity Mini-collection
The egg-drop activity is designed to help students develop a deeper understanding of the force created by wind resistance and how it interacts with the force due to Gravity. Students will note how surface area affects the resistance of a falling object as Gravity works on it. Students will record and share observations and questions regarding the experiment.

Testing alkalinity in water systems (simulation) part of MnSTEP Activity Mini-collection
This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals.

Visualizing Photosynthesis and Cellular Respiration part of MnSTEP Activity Mini-collection
The activity walks the students through the processes of Photosynthesis and Cellular Respiration.

Overnight Crystals to illustrate solubility concepts part of MnSTEP Activity Mini-collection
This quick-lab provides a concrete experience with crystal formation from saturated salt solutions that can help students make solubility problems more relevant to their experience.
