The lesson covered aquatic biomes, including freshwater ecosystems like rivers, lakes, and wetlands, and marine ecosystems divided into intertidal, neritic, pelagic, and abyssal zones. The learners discussed the characteristics of each zone and the types of organisms found there, as well as the importance of estuaries. This foundational biology topic is a key part of the curriculum for students at Southwestern College in Chula Vista. The next class is scheduled for Tuesday to continue with new biomes.

The lesson began with a review of food chains, energy pyramids, and the 10% rule. Following this, different types of terrestrial biomes—forests, grasslands, tundra, and deserts—were discussed, with a focus on their climate, geography, and biodiversity. For homework, one of the learners, a student at Indiana University Bloomington, was tasked with finding five examples of plants and animals for each biome.

During a recent biology lesson, an instructor and a student, who attends the University of South Florida in Tampa, thoroughly reviewed food chains, food webs, trophic levels, and energy transfer, including the 10% rule. The learner then practiced identifying producers, consumers, and and decomposers in both land and water food chains. To assess understanding, a worksheet on food chains was assigned, due before their next class.

In a recent lesson, two students discussed the differences between weather and climate, the flow of energy through ecosystems including producers, consumers, and decomposers, and the classification of consumers into herbivores, carnivores, and omnivores. One of the learners, who resides in Fort Wayne, will receive a snapshot of textbook notes from the other to help prepare for the next lesson. The next class is scheduled for Wednesday evening.

Shilpa Doultani tutored Rubi Rhea on pH calculations, balancing chemical equations (acid-metal carbonate reactions), neutralization, and Brønsted-Lowry acid-base theory. They practiced calculating pH and [H+] concentration, and Shilpa assigned Rubi additional practice problems on balancing equations and pH/pOH calculations to prepare for an upcoming exam. Rubi will complete a word document with balancing equations and email it to Shilpa, and also solve five PH and P questions that Shilpa will send.

Shilpa tutored Rubi in chemistry, covering mole concepts, stoichiometry, and gas laws through practice problems. Shilpa provided step-by-step guidance, and they planned a cumulative test to assess Rubi's understanding before her exam.
