This is a classroom activity where students create magnetic cats and see what occurs when the cats are placed next to each other. Students will be informally investigating magnetic attraction and repelling.

This activity is a field investigation where students go out to a water source and observe erosion that has taken place.

This field investigation of bedrock geology allows students to make observations, form questions, and conduct research to identify the evidence for volcanism in Minnesota.

This activity is a field investigation where students geologically map a defunct granite quarry in Saint Cloud Minnesota'sr Quarry Park.

This activity is a chemistry lab-based investigation where students apply observational skills and critical thinking skills to finding specific heat and heat capacity using different temperatures of water and solids. A final activity will assess students understanding of specific heat and heat capacity and promote data analysis skills, using real-life situations.

This model-making activity gives students an opportunity visualize Newtonian forces acting on a single point as well as combined forces acting to produce synclines and anticlines in Earth's crust. Students will analyze models to interpret findings of plate movements.

This is an activity demonstrating how pitch varies using water bottles, and allows students to investigate pitch further with rulers, straws, and water bottles.

This investigation involves a web quest and simulation to help students learn about the make-up and functioning of semiconductors as well as some applications. They will learn about p and n type materials, the pn junction, and what happens when an outside EMF source is added.

This activity is a field investigation where students list plants and animals they observe. Students will organize their data as producers, consumers, or decomposers and create a food web showing how they affect each other. They will predict what will happen if the food web becomes imbalanced by extinction or over population.

This activity is based on observations of mealworms form a question and make decisions as to the design of an investagation. Students use data collected to make a conclusion to their questions.

This activity is a combination of a field investigation and direct instruction at Minnehaha Falls. We are investigating Twin Cities rock types and weathering from the flowing water.

This activity is a field investagation where students will discover answers to their questions about the rock cycle.

Spreadsheets Across the Curriculum module. Students use the Compound Interest Equation and an annuity equation to calculate the growth of investments over time.

This activity will give kindergartner the chance to see what happend when they paint an iodine solution over a lemon juice message. They get to make thier own invisible message!

This is a POGIL activity geared for general chemistry students. The activity guides students through the process of determining how ionic and binary compounds are named as well as inorganic acids.

This activity is a hands on activity where students will gather information on their findings about iron in different cereals. Then use their finding and give reasonings of the differences and similarities.

This activity lends itself well to the review and repetition of previous topics and skills. The multi-faceted learning (and display of learning) is an excellent manner of getting the students to think about what they are doing and how they are answering.

This flash animation for the song "Irreplaceable" demonstrates how the availability of substitutes affects the price elasticity of demand. Beyonce notes that her current boyfriend is not "irreplaceable," meaning that her demand for him is elastic.

This activity is a mini-lab where students determine a procedure they might use to prove that air is matter.

This lab helps students to understand the density is state dependent and can change based on the state of the element.
