Podcasting is a powerful way for students to share their voice with the world. Along the way, they learn to communicate, engage in critical thinking, and go through the design process as they ultimately publish their work to an authentic audience. This site offers 20 creative ideas for podcasts you can do with your students.

Réseau de podcasts de culture générale
«Des podcasts courts et efficaces pour développer vos connaissances au quotidien. ...
Choses à Savoir est un réseau de podcasts de culture générale. 27 podcasts différents pour vous permettre de développer vos connaissances jour après jour.
Créé en 2015 par Louis-guillaume Kan-Lacas, Choses à Savoir rassemble aujourd’hui une équipe de passionnés (journalistes, professeurs, auteurs, scientifiques) bien décidés à partager leur savoir avec le plus grand nombre.
Chacun de nos épisodes est conçu avec en tête les 3 objectifs suivants: clarté, concision, stimulation intellectuelle. Nous en publions plusieurs centaines par mois.
Nous sommes aujourd’hui le réseau de podcasts le plus écouté de France (source ACPM) avec plusieurs millions d’écoutes mensuelles.»
Why do quantitative biologists sometimes claim that mRNA copy numbers are Poisson …
Why do quantitative biologists sometimes claim that mRNA copy numbers are Poisson distributed in simple models of gene transcription? The first video segment addresses this question under the simplifying assumption that mRNA degradation occurs after a well-defined, deterministic lifetime, and the second segment illustrates the same basic concept for the more realistic situation in which degradation is stochastic.

This free, online article, developed for elementary teachers, describes a Kindergarten polar science, standards aligned, unit centered on The Polar Express developing literacy, math, and science skills.

The result is an immersive, multimedia experience that brings players on a deep dive into key sequences and major science themes covered in the documentary and digital series. Using a combination of clickable 360 landscapes, 2D and 3D videos, animations, interviews with scientists, and mini-games, the Polar Lab takes players onto the ice and into the lab in search of evidence to answer big questions about Earth’s climate—past, present, and future. It also puts them in the driver’s seat, as they work with host Caitlin at “Polar Lab HQ” to collect data from the field, answer questions, and play games to keep the story moving through three action-packed missions…and what a story it is.

In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are included. This is part 1 of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences.
«Les étudiants prédiront la polarité des liaisons en utilisant les valeurs de l'électronégativité ; indiqueront la polarité avec une flèche polaire ou des charges partielles ; classeront les liaisons par ordre de polarité ; et prédiront la polarité moléculaire en utilisant la polarité des liaisons et la forme moléculaire.»

Students will recognize that pollinators play an important role in food production, gain an understanding of parts of plants, and see the way pollinators disperse pollen.

To gain a better understanding of the roles and functions of components of the human respiratory system and our need for clean air, students construct model lungs that include a diaphragm and chest cavity. They see how air moving in and out of the lungs coincides with diaphragm movement. Then student teams design and build a prototype face mask pollution filter. They use their model lungs to evaluate their prototypes to design requirements.

Graph reading and data analysis are highlighted in this activity where students identify the countries that produce the highest levels of polluting atmospheric emissions. They compare these data with the population of the countries, and describe how the percentage of total emissions and total population numbers are related. The resource includes the graph and a student worksheet. This is an activity from Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site.

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and ultimately, humans are responsible for it all.

To develop an understanding of modern industrial technologies that clean up and prevent air pollution, students build and observe a variety of simple models of engineering pollutant recovery methods: scrubber, electrostatic precipitator, cyclone and baghouse. In an associated literacy activity, students become more aware of global environmental problems and play a part in their solution by writing environmental action campaign letters.

We’re continuing our look at engineering materials with third main type of material that you’ll encounter as an engineer: polymers. They’re made of long, repeating chains of smaller molecules known as monomers and today we’ll explore their strange history of polymers and the things that contributed to how we use them today.

With a simple list of necessary supplies, science teacher Mrs. Seay gets her class completely involved in the task of identifying and classifying organisms found in local pond water.

Students design and build paper rockets around film canisters, which serve as engines. An antacid tablet and water are put into each canister, reacting to form carbon dioxide gas, and acting as the pop rocket's propellant. With the lid snapped on, the continuous creation of gas causes pressure to build up until the lid pops off, sending the rocket into the air. The pop rockets demonstrate Newton's third law of motion: for every action, there is an equal and opposite reaction.

Students will explain the concept of diversity and calculate various ways to measure diversities. Students will analyze data and factors limiting a population, and evaluate human impact on biodiversity. (Note: this unit was designed for an IB Environmental Sciences course.)

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than they are in another. How is that in any way useful to anyone ever? Hank uses the example a of West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar to what is called carrying capacity, the maximum population size that an environment can normally sustain), the initial organism gestation rate, and the availability of resources. How systems function often depends on many different factors. By altering these factors one at a time, and observing the results, students are able to clearly see the effect of each one.
