6th Grade English Vocabulary Part 3 in the online public school classroom

NEW : We have introduced interactive worksheets, puzzles, and quizzes on www.CompleteK12Essentials.com We have quick links to seamlessly move from our website to our Youtube channel.


Additional videos in this series will follow, so be sure to subscribe to our channel and tell a friend. If you have comments or suggestions on future videos please visit our channel link above.

_________________ABOUT_____________________
Complete K12 essentials Youtube channel and Complete K12 Essentials.com was created to offer parents and teachers an online augmentation or alternative when public schools are not available. The need for standard curriculum that can be delivered via the internet became obvious during the pandemic of 2020. Teachers and school districts were left to create lesson plans and somehow connect with the students with very little time. The challenge was to give each child a method to connect with teachers and class mates to simulate a natural learning environment. Although we are still building our library of video lessons, you can use our videos to create lesson plans, review standardized material, introduce building blocks and drills, as well as assigning tests and quizzes on limited videos, such as vocabulary. We are building videos that will serve all students from kindergarten through the 12th grade. Recently launched on June 21st, 2020 our goal is to provide videos that will serve as a resource for those teaching or those looking to cover important standardized curriculum. We believe that access to a solid foundation of knowledge should be available to everyone who chooses to seek it. Many offerings online lean on animation to capture a child’s attention, which to a certain extent works, but they lose interest rapidly and the opportunities for learning are significantly reduced. This is especially true when the child has no obligation to retain the material or accountability to a teacher. Navigating through the material suitable for each grade level is a difficult task at best, so we have created the “SAFE LEARNING PLACE” logo and apply it to all of our videos to show you our dedication to providing good learning material that can be trusted across our whole channel. The curriculum will cover Math, Language Arts, Social Studies, Science, Technology, Music, Art, Health and Fitness, Foreign Languages, Life Skills, Career training, History and Law.

How can you tell if harmful bacteria are growing in your food? Students learn to culture bacteria in order to examine ground meat and bagged salad samples, looking for common foodborne bacteria such as E. coli or salmonella. After 2-7 days of incubation, they observe and identify the resulting bacteria. Based on their first-hand experiences conducting this conventional biological culturing process, they consider its suitability in meeting society's need for ongoing detection of harmful bacteria in its food supply, leading them to see the need for bioengineering inventions for rapid response bio-detection systems.

In this video, we're going to be covering 10 rules (with exceptions) for how to know if a noun will be masculine or feminine in Spanish.

Please remember that you don't have to memorize this list of words/rules! But it might be a nice reference for you to watch every now and again.

And Native speakers don't even pay attention to the "rules". You'll notice that with animals especially they might make a gender for an animal that is grammatically genderless.

Regardless, hopefully you find this helpful! Enjoy!

👍Please share this video with others and like it to help me get the word out on my videos!

And let me know about other troublesome topics you’d like in bite-sized form.

Students design and construct electromagnets that must pick up 10 staples. They begin with only minimal guidance, and after the basic concept is understood, are informed of the properties that affect the strength of that magnet. They conclude by designing their own electromagnets to complete the challenge of separating scrap steel from scrap aluminum for recycling, and share it with the class.

Having bones is pretty cool. They make our blood, let us hear, and keep us from being just a squishy puddle on the floor. But for every species with bones, there are at least 20 species on Earth with exoskeletons instead. And those exoskeleton animals are incredibly tough and strong. So why don’t WE have our skeletons on the outside? This is the story of bones!

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.

Educational video for children to learn interesting facts and characteristics about butterflies. Butterflies are invertebrate animals belonging to the insect group. 99% of butterfly species are herbivores and eat leaves and nectar. Only 1% of species are carnivores and eat small insects. Their weight can range from 0.017 Oz and 0.019 Oz, and their length from 1 and 12 inches.

This is a very useful and interesting video resource for children, it talks about the most important butterfly details, as well as a lot of interesting facts about them. It is an excellent video for early childhood education

Students explore the physics exploited by engineers in designing today's roller coasters, including potential and kinetic energy, friction and gravity. First, they learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters. Second, they consider the role of friction in slowing down cars in roller coasters. Finally, they examine the acceleration of roller coaster cars as they travel around the track. During the associated activity, students design, build and analyze model roller coasters they make using foam tubing and marbles (as the cars).

Students explore the phenomenon of electricity as they learn about current electricity and necessary conditions for the existence of an electric current. To make sense of this phenomenon, students construct a simple electric circuit and galvanic cell to help them understand voltage, current, and resistance. They also use the disciplinary core ideas of energy and electric current to better understand the crosscutting concept of energy transfer.
