ELL students create and share a botanic field guide incorporating depiction, measurement, description, and classification of common Minnesota trees, shrubs, wildflowers, and plants.

This activity produces a fluent choral reading of Our Big Home: An Earth Poem, by Linda Glaser, when cooperative student groups rehearse, conduct vocabulary word study, and perform for their 4th grade peers.

In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air pollution. Specifically, students learn about the factors that affect water quality and the conditions that enable different animals and plants to survive in their environments. Next, students learn about groundwater and how environmental engineers study groundwater to predict the distribution of surface pollution. Students also learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. Additionally, students discover that the water they drink everyday comes from many different sources, including surface water and groundwater. They investigate possible scenarios of drinking water contamination and how contaminants can negatively affect the organisms that come in contact with them. Students learn about the three most common methods of waste disposal and how environmental engineers continue to develop technologies to dispose of trash. Lastly, students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. Also, they investigate the technologies developed by engineers to reduce air pollution.

Students develop critical thinking skills by interviewing a person who has perspective on environmental history. Students explore the concept of a timeline, including historical milestones, and develop a sense of the context of events.

In this activity, students create a "web" to identify and demonstrate the interactions among the living and non-living parts of an environment. This information allows students to better understand what an environment is and to also consider how engineers use teamwork to solve problems.

An activity designed to enable the students to access the impact of oil-development on environmentin Alaska. Students will draw conclusion based on various data and reading various views.

An important property of linear functions is that they grow by equal differences over equal intervals. In this task students prove this for equal intervals of length one unit, and note that in this case the equal differences have the same value as the slope. In F.LE Equal Differences over Equal Intervals 2, students prove the property in general (for equal intervals of any length).

An important property of linear functions is that they grow by equal differences over equal intervals. In this task students prove this for equal intervals of length one unit, and note that in this case the equal differences have the same value as the slope.

In this task students prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.

This task helps students understand the meaning of the equal sign and to use it appropriately.

This task asks students to use inverse operations to solve the equations for the unknown variable, or for the designated variable if there is more than one. Two of the equations are of physical significance and are examples of Ohm's Law and Newton's Law of Universal Gravitation.

This task requires students to use the fact that on the graph of the linear equation y=ax+c, the y-coordinate increases by a when x increases by one. Specific values for c and d were left out intentionally to encourage students to use the above fact as opposed to computing the point of intersection, (p,q), and then computing respective function values to answer the question.

We are obligated to provide enrichment opportunities and to appropriately challenge and engage these students. How do we find and monitor science enrichment activities for those students simultaneous to providing additional intervention and assistance to students who have yet to master the current concepts?

The purpose of this task is to directly address a common misconception held by many students who are learning to solve equations. Because a frequent strategy for solving an equation with fractions is to multiply both sides by a common denominator (so all the coefficients are integers), students often forget why this is an "allowable" move in an equation and try to apply the same strategy when they see an expression.

In this problem students must transform expressions using the distributive, commutative and associative properties to decide which expressions are equivalent.

This is a standard problem phrased in a non-standard way. Rather than asking students to perform an operation, expanding, it expects them to choose the operation for themselves in response to a question about structure. The problem aligns with A-SSE.2 because it requires students to see the factored form as a product of sums, to which the distributive law can be applied.

The purpose of the task is to get students to reflect on the definition of decimals as fractions (or sums of fractions), at a time when they are seeing them primarily as an extension of the base-ten number system and may have lost contact with the basic fraction meaning. Students also have their understanding of equivalent fractions and factors reinforced.

The accuracy and simplicity of this experiment are amazing. A wonderful project for students, which would necessarily involve team work with a different school and most likely a school in a different state or region of the country, would be to try to repeat Eratosthenes' experiment.

This activity is a field investigation where students find real-life examples of erosion in their school surroundings. Students will extend what they learned during stream table lessons about erosion, deposition, deltas, meandering streams, and dams.

This article provide a list of learning objectives and excerpts from the K-8 content standards of the National Science Education Standards that are associated with Principle 1 of the Seven Essential Principles of the Climate Sciences. Also provided are explanations of some common misconceptions on light, heat, and the seasons, plustools for formative assessment and ideas for teaching these scientific concepts. The article appears in the free, online magazine Beyond Weather and the Water Cycle, which focuses on one of the Seven Essential Principles in each issue.
