This document outlines a lesson plan on life energy processes and food production. It contains 4 stages: 1) explore, 2) firm up, 3) deepen understanding, and 4) apply. In the explore stage, students will assess their prior knowledge, be introduced to life energy processes, form questions, and generate ideas about how life energy can improve techniques and develop products. They will then group up to select ideas to challenge or explore further. The goal is for students to understand how life energy processes can be applied innovatively and profitably.

ICLR Friday Forum: Functional Recovery for Lifeline Infrastructure Systems (F...glennmcgillivray
On February 25, 2022 ICLR conducted a Friday Forum webinar titled 'Functional Recovery for Lifeline Infrastructure Systems', led by Craig A. Davis, Ph.D., P.E., G.E. of C A Davis Engineering.
Engineers design buildings and lifelines mostly to protect life safety, with few provisions to safeguard post-disaster functionality and recovery. Codes evolve, so older infrastructure tends to be less safe than new. As a result, natural disasters can damage utilities and transportation infrastructure (commonly called lifelines), kill and injure users, displace residents, close businesses, and cause other economic and socio-cultural harm. We cannot completely eliminate these risks, but we can improve community resilience by designing and retrofitting our lifelines with codes, standards, and policies that focus on post-disaster recovery. Engineers speak of these developing requirements and policies as “functional recovery,” meaning that we hope to design or modify lifelines to better ensure fast restoration of at least there basic functionality, even before all repairs are completed. Functional recovery requires acknowledging and accounting for the way lifelines interact—water service can rely on electricity and vice versa—so a functional recovery framework must ensure common degrees of reliability between interacting lifelines. In the United States, an effort is underway to develop recovery-based goals and functional-recovery design and retrofit guidelines and standards. The US Federal Emergency Management Agency and the National Institute of Standards and Technology are leading the development of recovery-based objectives for earthquake design, with consideration for future applications to other natural hazards.
Dr. Davis is a professional consultant on geotechnical, earthquake, and lifeline infrastructure system resilience engineering. He currently leads the development of functional recovery and operability concepts for lifeline infrastructure systems. Before opening a consulting firm, he led efforts to improve disaster resilience at the Los Angeles Department of Water and Power. He has written over 180 technical publications and has investigated numerous earthquakes.
Anaerobic Digester Workforce Training Curriculum DevelopmentLPE Learning Center
Proceedings available at: http://www.extension.org/67679
The Cornell University PRO-DAIRY Anaerobic Digester Workforce Development Project is a project funded by the New York State Energy Research and Development Authority, aimed at developing and delivering high quality educational programs targeted to a range of workforces within the dairy farm-based anaerobic digestion (AD) sector of the clean energy field. One of the barriers to growth of the AD industry in New York State, as identified by current AD operators, is the lack of a trained, skilled workforce to service and maintain different aspects related to the AD and biogas systems. These courses are aimed at developing a workforce to support this need, and to eliminate this barrier to growth.
Dr Wokje Abrahamse of Otago University and Dr Lauren Christie of Victoria University of Wellington present their views of research theory and engagement principles. Wokje introduces the theoretical barriers to change and discusses the results from a systematic review of 38 studies to determine the effect of interventions designed to conserve household energy use.
Given the findings from her PhD research, Lauren introduces five key principles that should be used when designing interventions to encourage the uptake of energy efficiency technologies. Both Wokje and Lauren conclude that in each and every case, 1 – the specific barriers to change for that target group and problem need to be understood first, and 2 – that a combination of approaches should be used.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

6. Stage 3
Teaching/Learning Sequence:
EXPLORE
As part of initial activities, learners shall be given an overview of life energy processes, what they are expected to learn
and how their learning shall be assessed. In this stage, diagnosis of their understanding life energy processes gained
from elementary science shall form part of the prerequisites. This also involves understanding or making meanings out
of the scientific knowledge obtained.
Learners shall:
1. undergo an assessment of their understanding of certain topics in elementary science such as different parts of the
plants, functions of each part, photosynthesis, and one-way flow of energy
(Suggestion: Assessment to use includes any of the following: paper and pencil test, use of checklist, use of
graphic organizer, pictures, etc. Teachers shall take note of learners’ prior knowledge and misconceptions, if any);
2. be introduced to the topic life energy processes
(Suggestion: Show video clips related to life energy processes. This could serve as a point of discussion among
the learners. This could also help the teacher in evaluating the prior knowledge of the learners.)
3. be oriented on related and varied resources and materials to be used in understanding life energy processes (see
resources and equipment/materials needed)
4. be given time to formulate questions on life energy processes and cluster these to initially find out what is/are
interesting for them
5. be given time to formulate other questions leading to the Essential Question with focus on how understanding of
life energy processes be used in improving certain techniques or practices and developing beneficial products
7. (Suggested Strategies: KWL, Focus Group Discussion, brainstorming, think-pair & square, dyads, round robin,
etc.)
6. generate as many tentative ideas (TI) to the Essential Question (EQ) as possible to show what they already know
about how life energy processes can be used in improving certain techniques or practices and developing beneficial
products
(Suggested Strategies: strategies to use include either brainstorming, Focus Group Discussion, graphic organizer,
concept mapping, etc. At this point, the teacher shall be careful not to reject learners’ opinion but shall encourage
them to give their ideas without being judged as right or wrong. Each tentative idea (TI) shall be written on the
board);
7. be grouped accordingly to choose some of the identified prior knowledge, alternative conceptions and tentative
ideas (TI). (Suggestion: Whatever each group of learners selected, the group shall be asked to challenge or
explore the validity of these prior knowledge, alternative conceptions or tentative ideas during the Firm Up Stage.)
8. be informed that they need to show their understanding of life energy processes in improving certain techniques or
practices and developing beneficial products
9. be informed that this product shall be assessed based on the following criteria: (a) innovativeness, (b)
marketability, (c) dependability, (d) profitability, (d) use of certain techniques and practices, and (e) manifestations
of life energy processes
(Suggested Activities: Brainstorming may be used to discuss how these criteria shall be used. For fast learners,
they shall be asked to develop their own criteria and rubrics and later compare these to the criteria found in this
Teaching Guide. Let them choose the most appropriate criteria by revising what they did or marrying both sets of
criteria so long as these will lead to an objective assessment of the product or performance. For average learners,
give them the criteria and develop the corresponding scoring rubric. Assist them to revise these rubrics until an
objective assessment can be made. For slow learners, give them the criteria and the rubrics. Ask them if they
understand and agree with these.)
8. FIRM UP
Varied learning experiences shall be introduced to help learners disprove alternative conceptions, examine/assess
prior knowledge, and begin to discover the validity of tentative ideas (TI) related to the EQ; make their understanding
of life energy processes real; equip them with skills and knowledge throughout the topic; and undergo differentiated
instruction to address their unique strengths and needs. This involves acquiring scientific knowledge which is about
accessing information, i.e., what information is needed, where information can be located and how information can be
gathered focusing life energy processes.
I. From Light Energy to Chemical Energy of Food
A. Introduction: Plant Parts and Functions
Using the chosen prior knowledge, alternative conceptions and/or tentative ideas (TI) to the EQ as starting/focal points
of investigation, learners shall:
1. classify the parts of a plant with complete parts according to their functions such as absorption of water and
nutrients, food production etc.)
(Main Ideas: Differentiation of the plant body into an underground root system and an aerial shoot system is an
adaptation to terrestrial life. The structure of roots is adapted to anchor the plant, absorb and conduct water and
minerals, and store food. The shoot system consists of the stems, leaves and flowers. The functions of the shoot
system include photosynthesis, reproduction, storage and transport.
(Suggested Strategies: cooperative learning, KWL, graphic organizers, oral sharing, meaning making, etc.)
(Suggested Activity: The learners may do the following activity and ask them to make inferences on
interrelationship of the plant organs based on activities performed.)
9. Directions: Classify the main parts of the plant according to the following functions.
a. leaves b. roots c. stem d. flower e. fruits f. trunk
Absorption of water Transport of water and Release of oxygen Food production Food storage
and nutrients nutrients
2. discuss concepts on specialized leaves, stems and roots;
(Main Idea: Modified structures with diverse functions have evolved in many plants for adaptation.)
(Suggested Strategies: discovery method, cooperative learning, etc.)
(Suggested Activity: Learners may observe specialized plant parts available in the school garden.)
3. revisit prior knowledge, alternative conceptions and/or TI on plant organ systems, if any.
(Suggested Activity: The teacher may ask each group of learners to discuss the prior knowledge, alternative
conceptions and/or TI which the group previously chose for investigation. This group shall be asked to reason out
for assessing, confirming or rejecting these respectively in the light of the activities conducted and analyses made
pertaining to plant organ systems.)
B.1. Light-dependent Reactions
Using the chosen prior knowledge, alternative conceptions and/or tentative ideas (TI) to the EQ as starting/focal points of
investigation, learners shall:
4. describe how requirements of the light reactions are obtained by plants
10. (Main Idea: The light-dependent reactions, or light reactions, constitute the first stage of photosynthesis, the
process by which plants capture and store energy from sunlight. In this process, light energy is converted into
chemical energy, in the form of the energy-carrying molecules ATP and NADPH.)
(Suggested Strategies: experimentation, modeling/teacher demonstration, concept mapping, etc.)
(Suggested Activities: Learners could relate the plant organs responsible for the acquisition of the requirements
for light reactions. The teacher may also let the learners perform LE Activity 1: Light and Chlorophyll
Development and LE Activity 2, Light and Photosynthesis. The teacher may present processes involved in light-
dependent reactions.)
5. revisit prior knowledge, alternative conceptions and/or TI on light reactions, if any.
(Suggested Activity: The teacher may ask each group of learners to discuss that prior knowledge, alternative
conceptions and/or TI which the group previously chose for investigation. This group shall be asked to reason out
for assessing, confirming or rejecting these respectively in the light of the activities conducted and analyses made
pertaining to light-dependent reactions)
B.2.. Light-independent Reactions
Using the chosen prior knowledge, alternative conceptions and/or tentative ideas (TI) to the EQ as starting/focal points of
investigation, learners shall:
6. describe how requirements of the light-independent reactions are obtained by plants;
(Main Idea: The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide
and other compounds into glucose.)
(Suggested Strategies: concept mapping, modeling/teacher demonstration, etc.)
(Suggested Activity: Learners could relate the plant organs used for the acquisition of the requirements for dark
reactions. The teacher may also present the processes involved in light –independent reactions. Note: Simulations
of these processes can be acquired from various resources such as video materials and internet.)
11. 7. compare the light and dark reactions
(Main Ideas: The light reactions produce oxygen gas and convert ADP and NADH+ into ATP and NADPH. The light
reactions take place within the thylakoid membranes. The dark reaction or Calvin cycle uses ATP and NADPH from
the light reactions to produce high-energy sugars. The Calvin cycle takes place in the stroma, the region outside the
thylakoid membranes.)
(Suggested Strategies: concept mapping, retelling, use of venn diagram, etc.)
(Suggested Activity: The teacher may show an instructional video of the light and dark reactions.)
8. summarize the factors that affect photosynthesis
(Main Ideas: Plants use photosynthesis to harness the energy in sunlight to make sugars from carbon dioxide and
water. The rate of photosynthesis is affected by light wavelength and intensity, temperature, humidity, carbon dioxide
concentration and water.)
(Suggested Strategies: role playing, collage making, use of graphic organizers, etc.)
(Suggested Activity: Learners in group may present differentiated activities that would summarize the factors
affecting photosynthesis. Activities may include role playing, collage making, etc.)
9. predict the possible effects of the oversupply and/or undersupply of the factors affecting photosynthesis

discuss among themselves how they could be able to present it in a creative and meaningful manner.)
15. discuss the stages involved in the sexual reproduction of flowering plants which include gamete formation,
pollination, pollen germination, double fertilization, fruit development and seed germination
(Main Ideas: Reproduction in angiosperms takes place within the flower. The anther produces male gametophytes,
the sperm is produced in pollen grains, which attach to the stigma on top of a carpel, in which the female
gametophytes (inside ovules) are located. After the pollen tube grows through the carpel's style, the sex cell nuclei
from the pollen grain migrate into the ovule to fertilize the egg cell and endosperm nuclei within the female
14. gametophyte in a process termed double fertilization. The resulting zygote develops into an embryo, while the
triploid endosperm and female tissues of the ovule give rise to the surrounding tissues in the developing seed. The
seeds develop inside protective structures called fruits. The seed will eventually germinate and grow into a new
individual. )

(Suggested Strategies: KWL, use of diagram or graphic organizers, etc.)
(Suggested Activity: The teacher may show an instructional video on respiration.)
22. explain how stored energy in glucose is released in respiration
(Main Ideas: Cellular respiration is the process that releases energy by breaking down food molecules in the
presence of oxygen. It has three main stages: glycolysis, Krebs cycle/citric acid cycle and electron transport. Each
of the three stages captures some of the chemical energy available in food molecules and uses it to produce ATP.
(Suggested Strategies: KWL, experimentation, think pair share, etc.)
(Suggested Activity: To test the speed of respiration, learners may perform LE Activity 8: The Rate of
Respiration.)
23. compare aerobic and anaerobic respiration in terms of ATP production and end products

respiration. The process of anaerobic respiration for production of energy can occur in either of the following: a.)
alcoholic fermentation wherein glucose is broken down to ATP, ethanol and carbon dioxide, b.) lactic acid
fermentation wherein glucose is broken down to ATP and lactic acid.)
(Suggested Strategies: use of graphic organizers, demonstration method, use of video materials and multimedia,
etc.)
(Suggested Activity: Learners may do LE Activity 9: Aerobic and Anaerobic Respiration.)
17. 24. cite situations that show how respiration occurs in organisms

of air: There are a number of fermentation pathways that different cells use. Yeast cells produce ethyl alcohol by
fermentation. Certain cells of our body, namely, muscle cells, use lactic acid fermentation. Depending on the
organism, some of the other products of fermentation include acetic acid, formic acid, acetone and isopropyl
alcohol.)
(Suggested Strategies: experimentation, think pair share, etc.)
