In this activity, students use datasets from both the Northern and Southern hemispheres to observe seasonal and hemispheric differences in changes to atmospheric C02 release and uptake over time.

In this math lesson, learners use yarn to measure lengths such as arm span and height. This gives learners practice measuring with nonstandard units. Pairs of learners also compare their height and arm spans. They practice problem-solving and reasoning skills by discussing why there are similarities and differences between the lengths of yarn that represent arm spans and height. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

Through investigating the nature, sources and level of noise produced in their environment, students are introduced to the concept of noise pollution. They learn about the undesirable and disturbing effects of noise and the resulting consequences on people's health, as well as on the health of the environment. They use a sound level meter that consists of a sound sensor attached to the LEGO® NXT Intelligent Brick to record the noise level emitted by various sources. They are introduced to engineering concepts such as sensors, decibel (dB) measurements, and sound pressure used to measure the noise level. Students are introduced to impairments resulting from noise exposure such as speech interference, hearing loss, sleep disruption and reduced productivity. They identify potential noise pollution sources, and based on recorded data, they classify these sources into levels of annoyance. Students also explore the technologies designed by engineers to protect against the harmful effects of noise pollution.

In this math lesson, learners measure distances using an outline cutout of their own feet. This enables learners to practice using nonstandard units. This activity is recommended as a follow up to the "Measuring with Teacher's Feet" lesson (see related resources). This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

After conducting the associated activity, students are introduced to the material behavior of elastic solids. Engineering stress and strain are defined and their importance in designing devices and systems is explained. How engineers measure, calculate and interpret properties of elastic materials is addressed. Students calculate stress, strain and modulus of elasticity, and learn about the typical engineering stress-strain diagram (graph) of an elastic material.

This is a problem-based learning adventure game that engages the player in the role of scientist, historian, and detective. At the beginning, the student is presented with a problem that must be solved. During the mission, students conduct field and laboratory investigations with the aid of the MedMyst characters. This mission can be played within one class period (approximately 30 to 45 minutes) and the knowledge gained from this mission will help students understand how infectious diseases are spread. This mission covers vectors, malaria, history of malaria, and immune system. Each mission is a self-contained problem and may be played without reliance on the other missions. Also available in Spanish.

This activity uses a mix of multimedia resources and hands-on activities to support a storyline of investigation into melting sea and land ice.

Insert channels in a membrane and see what happens. See how different types of channels allow particles to move through the membrane.

In this activity from NOAA's Okeanos Explorer Education Materials Collection, learners investigate how methane hydrates might have been involved with the Cambrian explosion.

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

Students obtain a basic understanding of microfluidic devices, how they are developed and their uses in the medical field. After conducting the associated activity, they watch a video clip and learn about flow rate and how this relates to the speed at which medicine takes effect in the body. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit. They conclude by solving flow rate problems provided on a worksheet.

Students learn about the form and function of the human heart through the dissection of sheep hearts. They learn about the different parts of the heart and are able to identify the anatomical structures and compare them to the all of the structural components of the human heart they learned about in the associated lesson, Heart to Heart.

Spreadsheets Across the Curriculum module. Students use Excel Solver to find the linear combination of servings of two specified foods that minimize cost while meeting nutritional requirements.

The activity is a field trip to Minnehaha Falls where students will observe and record their findings in a science notebook.

This activity is a classroom guided inquiry lesson where the student will sort, identify, and classify Minnesota fish.

This activity is a classroom and field investigation where students will group Minnsota fish families and create their own pop can fishing rods.

In this video segment adapted from Hope in a Changing Climate, learn how an environmentally devastated ecosystem has been restored, benefiting both the local economy and global efforts to fight climate change.
