In this lesson, students describe weather conditions using common tools to measure the weather and a science notebook to record their data. Students will continue to obserce the weather each day of the school year, looking for new developments in the weather and changes due to different seasonal changes.

In this activity, students analyze a Direct Measurement Video of a pendulum using Vernier LoggerPro. Students plot position and time using LoggerPro video analysis tools, and then make calculated columns that show gravitational potential and kinetic energies. Students see a clear graphical representation of the relationship between the motion of the pendulum and the mechanical energies.

In this lab activity, students not only explore the meaning of density, but also use their math skills to graph mass/volume data, write an equation for a line and interpret the slope of the line. Students also find the density of two unknown mineral samples and use those values to differentiate between the two minerals. At the end of the lab, students and teacher discuss the following ideas: (1) density is a physical property that is independent of sample size, (2) why the students' measured density values are not the same as the known density values reported in the textbook , and (3) the "messy" nature of science, which requires multiple and repeatable measurements and requires careful attention to detail.

In this lesson, students will investigate two of the gas laws: Charles and Boyle's through a lab activity.

The students will discuss, define, and demonstrate the Earth's rotation and revolution around the sun. The students work as a whole class and in small groups to determine Minnesota's seasons in relationship to its revolution around the sun. Each group will write a paragraph explaining their reasoning (prediction). After whole group discussion, each student will reflect on his or her prediction (correct or incorrect and why).

In this lab activity, students will investigate a single replacement reaction while also determining mole ratios to determine percent yields.

In this lab activity, students will react magnesium with hydrochloric acid to produce hydrogen gas and collect data with a Vernier Gas Pressure sensor. The concepts of stoichiometry, ideal gas law, combined gas law, standard temperature and pressure, and the molar volume of a gas will all be used in this experiment.

In this lesson, students investigate motion graphs. Students predict what the distance-time and velocity-time graphs would look like for a student walking across the room for several different scenarios. Then students will use a motion detector to act out these scenarios and compare their predictions to those produced from the motion detector.

In this lab activity, students act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law. The emphasis here is on the process of science rather than the actual results. Students need to focus on how they would design a procedure to test Newton's hypothesis and then communicate that idea to others.

In this activity, students use miniature explosives (anatacid tablets and water in a film canister) to analyze action and reaction forces. Students will also explore how mass will affect the experiment. The distances that each canister travels is measured, recorded and later analyzed and discussed.

In this lab activity, students investigate the motion of different skateboarders pulled with various values of constant force. Using skateboarders of different masses and a variety of constant force values, students produce distance-time graphs for a number of trials. Students will then analyze the data using Newton's second law and discuss differences between trials, the effects of friction, and possible sources of error in the experiment.

In this activity, students will explore their location's climate in order to inform a pen pal of the type of weather he or she can expect to experience during an upcoming visit. Students will generate and explore a variety of graphs, charts, and map images and interpret them to develop your understanding of normal climate.

In this activity students will explore the weather in their area. Students will generate graphs, maps, and charts to develop an understanding of climate.

In this activity students will learn to analyze climographs to learn about the climate of an area.

In this activity, students will generate and view maps of average annual temperature and precipitation.

In this activity, students will explore leaves using inquiry and their senses. The students will go on a leaf walk investigating different leaves. They will bring back a few to the classroom to continue the investigation. The students will then draw and write about one of their leaves and then share with a partner and then the class.

In this unit students will learn what ocean acidification is and why it is happening, describe ways in which individual species and marine ecosystems might respond to ocean acidification, and describe how ocean acidification will impact the ability of oceans to sequester carbon.

In activity Part A, students will analyze a time-series graph to search for relationships between trends in atmospheric CO2, dissolved CO2 in seawater, and changes in ocean pH. Then, they will carry out a class experiment on the effects of increased amounts of CO2 on pH in sea water. This activity also focuses on understanding pH and ocean acidity. Included is a short interactive video about acids, bases, pH, and ions.

In activity Part B, students will review and analyze the results of research compiled by the Woods Hole Oceanographic Institute on the effect of ocean acidification on a variety of marine organisms. Students will then conduct their own research in a virtual laboratory interactive developed by Stanford University.

After completing this investigation, students should be able to: describe the biological and physical processes that make the ocean a carbon sink; describe the role of phytoplankton in maintaining the ocean biological pump- an important biological process; and use systems thinking to predict the causal effects of warmer water on the biological carbon pump
