After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts of density and miscibility relate to water chemistry and remediation. Topics covered include miscibility, immiscibility, hydrogen bonds, hydrophobic and hydrophilic. Through the density column lab activities, students see liquids and solids of different densities interact without an understanding of why the resulting layers do not mix. This lesson gives students insight on some of the most fundamental chemical properties of water and how it interacts with different molecules.

In this field lab activity, students will determine the density, pH and water content of prairie soil, transition soil, woods soil, and riverbed soil and compare their findings.

Get your students interested in learning about ecological interactions with this One Direction music video parody.

This resource is about exploring how relationships are formed in an ecological system. Whether it be in a community, population, or even in a predator/prey situation. Energy flows through chains, webs, and pyramids in an ecological system. Understanding this energy flow helps us to see the diversity of the ecosystem and its inhabitants.

This video resource is presented as a real-world application of chemistry in the field of archaeology. Conservator, Nichole Doub, walks through the process of electrolytic reduction and how it is used to conserve archaeologically recovered artifacts. Use to support Maryland/NGSS for grades 5, MS, and HS. For 5-PS1-1, pair with the Exploratorium's "Copper Caper" activity for a similar reaction which can be conducted safely in the classroom--have students watch the video and discuss why the spoon formed tarnish and why the tarnish was not visible as particles moved from the spoon to the sacrificial anode. For MS-PS1-1, pair with the Exploratorium's "Indicating Electrolysis" activity and have the students explain the charges of oxygen/hydrogen and compare/contrast those with the silver and sulfur in the tarnish. Have students research silver sulfide (the usual tarnish found on silver artifacts) and model a single molecule of it before and after electrolysis. For HS-PS1-1 have students research silver sulfide and model a molecule of it prior to watching the video and predict what will happen when the positive or negative charges change. For HS-PS2-6, have students postulate why, historically, coins were made from silver and gold (with reference to their chemical reactions), then have students design a coin and specify a different metal to make it out of, explaining why the atomic properties of that metal make it appropriate for use in currency.

The students participate in many demonstrations during the first day of this lesson to learn basic concepts related to the forms and states of energy. This knowledge is then applied the second day as they assess various everyday objects to determine what forms of energy are transformed to accomplish the object's intended task. The students use block diagrams to illustrate the form and state of energy flowing into and out of the process.

Under the "The Science Behind Harry Potter" theme, a succession of diverse complex scientific topics are presented to students through direct immersive interaction. Student interest is piqued by the incorporation of popular culture into the classroom via a series of interactive, hands-on Harry Potter/movie-themed lessons and activities. They learn about the basics of acid/base chemistry (invisible ink), genetics and trait prediction (parseltongue trait in families), and force and projectile motion (motion of the thrown remembrall). In each lesson and activity, students are also made aware of the engineering connections to these fields of scientific study.

Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well. They will then pair with another superhero and create a dynamic duo out of the two elements, which will represent a molecule.

Students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending and torsion. In this activity, students play the role of molecules in a beam that is subject to various loading schemes.

This activity is an extension where students freeze a liquid, making ice cream.

In this 7th grade science lesson, students identify desirable traits in plants and take cuttings from parent plants to facilitate asexual propagation and produce offspring with identical DNA.

In this 7th grade science lesson, students review the structures and processes that allow flowering plants to reproduce, and then pick a flower from the garden to dissect and diagram.

In this 8th grade science lesson, students review the six essential elements of life and discuss how they function in the garden.

In this 6th grade Science class, students learn how to build a compost pile, learn about organisms needed for decomposition, and begin to understand the purpose of compost in the garden.

In this 6th grade science class, students consider how they use water in their daily lives and learn that water is a nonrenewable resource in a closed system.

In this 7th grade science lesson, students are introduced to the food system and play an interactive game called The Wind Blows.

In this 6th grade science lesson, students are introduced to the garden as a classroom. They meet the garden staff, tour the garden, learn the basic systems and routines of the garden classroom and are introduced to the Edible Schoolyard life skills and values.

In this 7th grade science lesson, students learn about levers and use them to make-work easier.

In this 7th grade science lesson, students deepen their understanding of pollen and pollinators by practicing the use of microscopes to observe pollen and bee species from the garden.

In this 6th grade science class, students observe mushrooms growing wild in the garden, handle examples of common edible mushrooms and learn about the lifecycle of fungi.
