This is a classroom activity in which students will observe, question, and investigate the relationship between the sun and the earth and how that relationship causes day and night.

In this activity students investigate soil pH differences and buffering capacity as it relates to acid rain, interpret and present their findings, and develop a new, experimental question.

This activity is a classroom quick lab where students explore sand, soil, and water in relation to absorption and permeability.

This activity is a guided inquiry investigation where students gather data on which soil is the best for growing plants. Student will interpret their data, and develop a conclusion from the data. The student will determine which type of soil they would like to use in the next activity of making their own terrariums. The data collected could lead to further questions, which can be investigated in some extension activities.

This guided inquiry is a laboratory investigation on soil textures where students gather and analyze data, compare findings and develop new experimental questions.

Open tube resonators of nearly identical length produce sound waves with frequencies very close together. The difference between the two frequenciesy is the beat note frequency heard when two resonators (musical intruments)are slightly out-of-tune.

This activity is a classroom experiment where students learn about sound. Students will use musical instruments to explore the relationship between length and pitch.

This activity is a classroom activity where students use the inquiry method to answer the question "How is sound made?" by observing different sound producers and coming up with their own conclusion.

Students gather data on miniature cars and use this data to calculate speed and acceleration.

This activity is a guided exploration of how static electricity works and how it relates to lightning.

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.

This activity is a classroom investigation where student observe several properties of water; adhesion and cohesion. They will transfer this knowledge to predicting other materials that will have adhesion with water molecules.

This activity is a classroom activity where students will create a collage of pictures based upon precipitation/water during each season.

In this biology investigation, students will make observations of the growth of bean seeds to determine what plants need to live and grow in a healthy way.

This activity is an investigation of what colors make up white light. Students will explore through two different hands-on activities.

This activity is a classroom lab where students test common household liquids for pH level on the pH continuum, 1-14. They compare and contrast everyday use of the liquids, and how this relates to the liquids' pH property.

In this physics interactive lecture demonstration, students will investigate the effects of acceleration due to gravity in a number of different situations using a plastic water bottle. Based on an original activity from Peter Hopkinson, AAPT.

This observational inquiry activity involving careful descriptions of rocks and fossil including age will be used to create a scalar accurate geologic time scale. Students will observe and learn that the geologic time scale was created based on changes in fossil, rock, and atmospheric changes.

This guided inquiry activity is designed to help students understand the effectiveness of inclined planes to reduce the amount of force needed to move an object.

Students use an inquiry approach to describe the major biomes of Minnesota before taking a look at adaptations that make organisms successful in their environments.
