How do i start a flip classroom?

 1.    Determine the technology required: You will require an online platform (such as Google Classroom, Edmodo, or Schoology) to host your video lessons, as well as other materials such as documents and worksheets. If you intend to create your own video lessons, you may also need to invest in recording equipment. 2. Create your video lessons: Determine which topics you want to cover and then create your video lessons. You can create your own videos on a computer or tablet, or you can host videos created by other educators on platforms such as YouTube or Vimeo. 3. Plan activities for in-class time: For the in-class portion of the flip classroom, plan activities that encourage students to engage with the material and apply what they've learned. To help students further explore the topics, use group discussions, problem-solving activities, and projects. 4. Explain the flip classroom concept: Before you begin your first flipped lesson, explain to your students what the flip classroom is and how it works. Make it clear to them that they are responsible for watching the video lessons and participating in the in-class activities. 5. Evaluate and adjust: Take some time after each lesson to reflect on how it went. Request feedback from your students and make changes as needed to ensure that the flip classroom is meeting its objectives.

What are the advantages and disadvantages of a flip classroom?

 Advantages:

1.    Increased student engagement: In a traditional classroom setting, it can be difficult to keep students engaged in the lecture. In a flipped classroom, students are actively involved in the learning process and can take ownership of their learning. 2. Students can work at their own pace: Students can work at their own pace and can replay video lessons if they need to review something that was covered in the lesson. This can help them better understand the material and can help them keep up with the rest of the class. 3. Less pressure on teachers: In a flipped classroom, teachers have more time to interact with students and answer questions, rather than spending all of their time lecturing. This can help teachers create a better learning environment for their students. 4. Increased access to technology: Flipped classrooms give students access to technology, which can help them learn more effectively and efficiently.

Disadvantages: 1. Difficulty in implementation: Flipped classrooms require a lot of preparation and planning, which can be difficult for teachers who don’t have the resources or the time. 2. Technology issues: Technology can be unreliable and can cause problems with flipped classrooms. 3. Lack of student motivation: Some students may not be motivated to watch the videos or do the assignments, which can lead to a decrease in learning. 4. Low engagement in video lessons: Video lessons can be boring and lack the engagement of a traditional classroom setting.

Which is the Flipped Workshop model in flip classroom?

 The Flipped Workshop model is a type of Flipped Classroom model that is based on problem-based learning principles. Students in this model are assigned to conduct independent research and problem solving prior to attending class. The teacher serves as a facilitator during class, guiding students as they work in small groups to discuss and solve the problem. Students must be ready to present their findings and solutions to the class.

Which is the Flipped Video model in flip classroom ?

 It is an instructional model that emphasises student-centered learning. It is predicated on the idea that students can watch instructional videos at home and then use class time for activities like discussion, problem-solving, and application. Teachers create videos that explain course material and assign them as pre-class assignments in this model. Teachers facilitate learning in the classroom through activities and discussions.

Which is the jigsaw model in flip classroom?

 The Jigsaw Model is a cooperative learning strategy in which students are assigned roles and complete a task in small groups. This model is frequently used in a flipped classroom, where students are given tasks to complete before class so that class time can be spent on more interactive activities like discussion and collaboration.

What is the role of a teacher in flip classroom?

 

In a flipped classroom, the teacher's role is to provide meaningful and engaging instruction, to create an environment that encourages student collaboration and problem-solving, and to facilitate learning in a way that maximises student engagement and understanding. The teacher should also be prepared to provide individualised support and feedback to each student as needed. Furthermore, the teacher should provide students with guidance and support as they explore, discover, and apply new knowledge and skills.

The best flip classroom model will be determined by the students' individual learning needs as well as the classroom's goals. The "Jigsaw" method, the "Flipped Video" method, and the "Flipped Workshop" model are all popular.

What is a Flip classroom?

 What exactly is a flip classroom?

The flip classroom teaching method is becoming increasingly popular around the world. According to a National Center for Education Statistics report, over 30 countries use the flip classroom teaching method in some form.

It is an instructional strategy and type of blended learning that flips the traditional learning environment by delivering instructional content outside of the classroom, frequently online. Rather than introducing new concepts in class and then assigning homework, the teacher assigns learning activities as homework and uses class time to work through activities and problems.

Grey Goo

It is a term used in nanotechnology

It refers to a disaster scenario in nanotechnology applications. 

What is nanotechnology

We can say it is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes,

In 1959, American physicist and Nobel laureate Richard Feynman introduced  the concept of nanotechnology. Throughout the 1990s, significant advances in nanotechnology, such as carbon nanotubes, were made. Nanomaterials were being used in consumer products even in the early 2000s. Although modern nanotechnology is relatively new, nanometer-scale materials have been used for centuries.

Now lets come to Grey goo

Kim Eric Drexler In his book "Engines of Creation," proposed an intriguing possibility for nanotechnology. Drexler imagined a future in which tiny machines known as assemblers could construct materials molecule by molecule. Using billions of these assemblers, you could create almost any material we can think of. The role of assemblers would be to put the molecules together precisely and produce what we want.

How do you manage to hire so many assemblers? You start by making a few in the lab. The assemblers are then instructed to construct other assemblers. In turn, these new assemblers will start building more machines. With each generation, the manufacturing rate becomes exponential, doubling.

But what if the production spirals out of control? This would result in the grey goo scenario. Assemblers would start converting all organic matter into more assemblers, consuming everything. The Earth would be reduced to a lifeless mass of nanomachines.

What is positive about grey goo

The potential of self-replicating machines. It can be used to solve energy-related problems like producing low-cost solar power, cure fatal diseases like cancer by boosting the human immune system, completely clean up the environment, and even allow for the restoration of extinct species.

Because the technology's basic building blocks are at the molecular level, the cheapness and abundance of materials would make it simple and inexpensive to create any product, even cheap pocket supercomputers.

Many scientists believe that building assemblers will be impossible for the foreseeable future.

Furthermore, due to the enormous complexity involved, creating such nanobots is difficult, and given current technological limitations, they are unlikely to be easily created. (Drexler himself has stated that such self-replicating machines would be unlikely to be built due to manufacturing inefficiency.)

Though Grey goo is not of concern yet, those working in nanotechnology should be aware of this.

Pressure Cooker Spill? Add few drops of oil

 Pressure Cooker Spill? Add few drops of oil

The surface tension of water is higher. The surface tension of water is 72 dynes/cm, while the surface tension of oil is 30–35 dynes/cm.

This causes water to spill out of pressure cookers.

Now Swacch cookers are introduce as an alternate remedy.

Addition of few drops of oil to dhal in a pressure cooker redues the surface tension of water and prevents spill.

Addition of castor oil to dhal is beneficial as it helps in bowel movement and  increases omega -3 – fatty acids 

Crown Shyness- an interesting phenomenon in nature!

 

What is this crown shyness? It is something seen in trees. The above pictures show a clear outline between trees as if social distancing is practiced!! 

When the tops of individual trees in the forest canopy avoid touching, it creates separation lines and boundaries in the sky. Crown shyness is the distinctive border that forms around trees.

Crown shyness (also known as canopy disengagement, canopy shyness, or intercrown spacing) is a phenomenon observed in some tree species in which fully stocked tree crowns do not touch each other, forming a canopy with channel-like gaps.

This crown shyness, may help trees in sharing resources and staying healthy.

Rupert's drop

 

Rupert's Drop

Prince Rupert’s drops are formed by dropping hot molten glass into cold water.

This gives a drop like tadpole shape (see the image taken from Creative common licence). The drop has a strong head and a tail.

This develops opposing forces of high compressive strength on the outside and high tensile strength on the inside making the tail incredibly sensitive. Even if you hit the bulky head portion with a hammer or a hard material it doesn’t break nor can a bullet pierce through.But if the tail is disturbed, then the drop is no more hard.

 

The drop becomes fragile when the  tail is distorted. Because of those opposing forces, a minor distortion to a drop’s tail causes the whole structure to explode, almost at 1lakh frames /second.

These drops are also called Batavian tears

Prince Rupert's drops were discovered in the 17th century

Rupert of Bavaria presented 5 drops to Charles II of England. These were turned over to the Royal Society for study in 1661.
