This database of lessons is provided to support agriculture education in California classrooms. Over the last century, children have become further removed from the land that feeds and clothes us. And yet, Agriculture is the very basis of civilization—the food we eat, the clothing we wear, the material of our homes and many of our traditions and values…all coming from agriculture and collectively setting the pace for a nation's standard of living. The California Foundation for Agriculture in the Classroom works with K–12 teachers, and students to enhance education using agricultural examples.

After completing the associated lesson and its first associated activity, students are familiar with the 20 major bones in the human body knowing their locations and relative densities. When those bones break, lose their densities or are destroyed, we look to biomedical engineers to provide replacements. In this activity, student pairs are challenged to choose materials and create prototypes that could replace specific bones. They follow the steps of the engineering design process, researching, brainstorming, prototyping and testing to find bone replacement solutions. Specifically, they focus on identifying substances that when combined into a creative design might provide the same density (and thus strength and support) as their natural counterparts. After iterations to improve their designs, they present their bone alternative solutions to the rest of the class. They refer to the measured and calculated densities for fabricated human bones calculated in the previous activity, and conduct Internet research to learn the densities of given fabrication materials (or measure/calculate those densities if not found online).

Students construct three-dimensional models of water catchment basins using everyday objects to form hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human activities. Students discuss how engineers design structures that impact water collection, as well as systems that clean and distribute water.

Students drop marbles into holes cut into shoebox lids and listen carefully to try to determine the materials inside the box that the marbles fall onto, illustrating the importance of surface composition on dolphins' abilities to sense materials, depth and texture using echolocation. This activity builds on what students learned in the associated lesson about bycatching by fisheries and how it affects marine habitats and species, especially dolphins. Students learn how echolocation works, why certain animals use it to determine the size, shape and distance of objects, and how people can take advantage of dolphins' echolocation ability when developing bycatch avoidance methods.

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the current, I, for each set resistance value, students plot the three points on a Cartesian plane and note the line that is formed. They also see the direct correlation between the amount of current flowing through the lamp and its brightness.

Few people are aware of how crucial the sense of smell is to identifying foods, or the adaptive value of being able to identify a food as being familiar and therefore safe to eat. In this lesson and activity, students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. The teacher leads a discussion that allows students to explore why it might be adaptive for humans and other animals to be able to identify nutritious versus noxious foods. This is followed by a demonstration in which a volunteer tastes and identifies a familiar food, and then attempts to taste and identify a different familiar food while holding his or her nose and closing his or her eyes. Then, the class develops a hypothesis and a means to obtain quantitative results for an experiment to determine whether students can identify foods when the sense of smell has been eliminated.

"Resistance to therapy is a major hurdle in current cancer treatments. A major part of the problem is heterogeneity. Tumors, by their nature, have multiple cell lineages with varying characteristics. Among these are cancer stem cells (CSCs). CSCs can regenerate a tumor even after treatment kills many of its other cells. And they can go dormant, transport drugs outside the cell membrane, avoid apoptosis, and express resistance-conferring non-coding RNAs, all of which boost tumors’ resistance to treatment. A new review describes common CSC surface markers, deregulated signaling pathways, and resistance mechanisms as well as the status of research into CSC therapies. Current therapies targeting CSCs do not address tumor heterogeneity or the complexity of the tumor microenvironment..."

"Viral infection can be devastating. But some viruses are an important part of therapies for fighting diseases like cancer. Adenoviruses are one example – they deliver deadly payloads to cancer cells without harming healthy tissue. Or do they? A recent study suggests that adenovirus infection could promote the formation of glioma stem cells, the self-renewing cells that keep brain tumors alive and spreading. Experiments on glioma cells derived from human patients showed that adenovirus infection promoted the formation of tumorspheres, solid, spherical formations that develop from self-renewing glioma stem cells. When transplanted into mice grafted with glioma tumors, these formations promoted tumor growth. A closer look revealed three signaling molecules that adenoviruses activate during this process: TLR9, a pro-inflammatory receptor, NEAT1, a non-coding RNA frequently overexpressed in human tumors, and STAT3, a protein linked to tumor formation..."

Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and adhesive forces (the forces that causes water to "stick" to solid surfaces. The interaction between cohesive forces and adhesive forces causes the well-known capillary action. Students are also introduced to examples of capillary action found in nature and in our day-to-day lives.

As part of a (hypothetical) challenge to help a city find the most affordable and environmentally friendly way to clean up an oil spill, students design and conduct controlled experiments to quantify capillary action in sand. Like engineers and entrepreneurs, student teams use affordable materials to design and construct models to measure the rate of capillary action in four types of sand: coarse, medium, fine and mixed. After observing and learning from a teacher-conducted capillary tube demonstration, teams are given a selection of possible materials and a budget to work within as they design their own experimental setups. After the construction of their designs, they take measurements to quantify the rate of capillary action, create graphs to analyze the data, and make concluding recommendations. Groups compare data and discuss as a class the pros and cons of their designs. Pre- and post-evaluations and two worksheets are provided.

"For decades they’ve taken a backseat to their mineral counterparts. But today, organic materials are booming—not least of all for their applications in lithium-ion batteries. A new review article published in the journal ChemPlusChem discusses how one class of organics in particular is poised to yield high performance from a tiny but versatile package: carbonyl-based π-conjugated compounds. Like other organic materials, carbonyl-based π-conjugated materials present a unique and much-needed solution to the global energy crisis. Flexible, light, and naturally abundant, these compounds offer the prospect of nimble energy-storage systems with energy and power densities comparable to inorganic systems. What sets carbonyl-based π-conjugated materials apart from other organics is highly tunable electrochemical performance stemming from a versatile starting structure. The redox mechanism of carbonyls proceeds by a reversible one-electron reduction to form a radical mono-anion and the reverse reaction..."

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture. This activity was inspired by the Cabaret Mechanical Theatre, a group of automata builders based in England. Artists like Paul Spooner, Keith Newstead, and Carlos Zapata build beautiful narrative pieces using elegant mechanisms based on cams, gears, springs, and linkages. Working with simple materials, this activity is easy to get started, and may become as complex as your mechanical sculpture ideas.
