Alexander Eden – Connected Science Learning, 2024
It is critical to develop students' science communication skills as they progress through their education. One way this goal can be accomplished is by integrating Flip into educational programs. Through Flip educators create prompts that students respond to in video form, which leads to deeper discussion on various topics. This brief will share an…

Dykes, Jeff; Johnson, Kathleen; Cousins, Julia; Simpson, Leo; Hull, Iver – Bioscene: Journal of College Biology Teaching, 2021
We used a novel approach that combined direct PCR of plant tissue and SRAP DNA fingerprinting to seek to identify the crosses made in "Brassica rapa" used in the Wisconsin Fast Plants. Our goal was to develop a rapid method for students to use in a biology, botany, or genetics class to identify the parental types (purple stem, non-purple…

Daisuke Kajiya – Journal of Chemical Education, 2023
The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

Philip A. Kocheril; Makaela M. Jones; Jessica Z. Kubicek-Sutherland – Journal of Chemical Education, 2022
Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

Maeng, Jennifer; Gonczi, Amanda – Science Teacher, 2019
The idea that plants do photosynthesis but do not do cellular respiration is a common misconception among middle and high school students that often stems from an over-simplification of these processes in diagrams and formal science instruction. The activity presented here uses a conceptual change approach (Nussbaum & Novick, 1982) and an…

Fry, Kym; English, Lyn D. – Mathematics Teacher: Learning and Teaching PK-12, 2023
How might fourth graders address the problem of measuring the size of a leaf? And why might their classroom teachers choose such a shape to measure? One group of fourth-grade students in an urban Australian school were interested in knowing the sizes of leaves on a passionfruit vine growing at their school. The children were excited after a visit…

Arturo Garci´a-Zavala – Journal of Chemical Education, 2023
Poinsettia ("Euphorbia pulcherrima") contains anthocyanins that dissolve in water and exhibit color changes due to changing pH. This property makes the poinsettia extract a useful acid-base indicator for pH demonstrations. When combined with common household materials, this experiment can be used as an alternative low-cost tool in…

Mayta, Martín L.; Dotto, Marcela; Orellano, Elena G.; Krapp, Adriana R. – Biochemistry and Molecular Biology Education, 2022
The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

Lauren A. Keiller; Iain L. J. Patterson; Dominic M. Stewart; Iain A. Smellie – Journal of Chemical Education, 2023
The use of red cabbage ("Brassica oleracea var. capitata F. rubra") extract as a pH indicator is a versatile and popular demonstration that is employed by educators in many schools and universities. Previous variations of this demonstration have used red cabbage extracts to prepare paper that changes color when solutions of acid or base…

Wallee Naimi; Gail A. Vinnacombe-Willson; Stanley Saldana; Lionnel Ronduen; Heather Domjan; Naihao Chiang – Journal of Chemical Education, 2024
Stimulating interest in science at an early age is important for STEM education. This work details an educational activity utilizing the anthocyanins found in butterfly pea flowers ("Clitoria ternatea"). This activity was developed for use in official classroom settings, online, and/or at-home with parental or educator guidance. Primary…

Hooper, Clea – Teaching Science, 2022
In 2020, just as COVID-19 reached Australian shores, a group of enthusiastic teachers had been anticipating their imminent Bush Blitz TeachLive expedition to Rungulla National Park to take part in Australia's largest biodiversity survey. It took two years for their trip to eventuate, but it was worth the wait. Three candidates from the deferred…

Ciaccio, James A.; Hassan, Kareem – Journal of Chemical Education, 2020
Column chromatography of photosynthetic plant pigments is a common experiment in introductory laboratory courses for science majors and nonscience majors alike. We report a simple, rapid, reproducible, and small-scale solid--liquid extraction of photosynthetic pigments from inexpensive, store-bought dried herbs that affords a dark-green extract…

Wong, Choun Pei; Subramaniam, R. – Journal of Biological Education, 2022
While the use of ICT technologies in biology lessons is becoming more pronounced, it is not yet the case for those related to the use of advanced technologies. In this article, we focus on the use of an infrared camera for developing applications in biology. Infrared thermal imaging has become increasingly affordable, and it is now time for…

Jeffrey Grant; Patrick Murphy; Rebecca S. Barak; Marlene Hahn; Emma Leavens; Andrew L. Hipp – American Biology Teacher, 2025
High school biology students are provided few classroom opportunities to learn natural history or to see themselves as scientists. This poses a risk to their gaining the basic knowledge needed to play a positive role in the biodiversity crisis. However, science-as-practice in the classroom introduces the opportunity to equip students with…

Ross, Keith – School Science Review, 2021
We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…
