Answer:

Conducting online classes isn’t always easy and it needs creative thoughts to make students attentive. Teaching online requires completely different skillsets compared to physical classes.

However, my school and my teachers made our online class joyful, interesting, and effective during the pandemic. My teachers turned on the camera and engaged directly with students.

They are always energetic. The size of each class used to be not more than 20 screens. Online classes were recorded and have the accessibility of viewing whenever required.

Our teachers used whiteboards, pointers, screen sharing tools to make our classes effective. After completion of each lesson, we were engaged in polling. It helped in determining the student’s level of knowledge on a particular topic.

To engage the digital abilities, students should already have and create dynamic collaboration experiences that prepare your students for our digitized, globalized world.

Teachers should see collaboration and action through real classroom examples and learn a proven framework for effectively integrating collaboration into their instruction.

Answer:

Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as 'summer sleep'), helping to escape warm climates.

Snails need moisture to survive; so, if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as ‘summer sleep’), helping to escape warm climates. During this time, the snails will secrete mucus over their bodies to protect themselves from the dry, hot weather. As glamorous as it may sound, snails don’t always sleep for three years in their own mucus. When the weather is just right, snails do tend to follow a pretty regular sleeping schedule.  

At first glance, you may not assume that land snails live very fascinating lives. However, these gastropods live quite unique lifestyles. These animals are hermaphrodites, which means they have both male and female reproductive organs. They have no sense of hearing, and salt is potentially toxic for them. However, one of the most interesting aspects of their life is how they sleep. Exactly, how long can certain snails sleep for? You may be surprised by the answer.

How Long Can Snails Sleep?

Certain land snails can sleep for up to three years in hibernation or estivation. Yes, it’s true!  Although this extended nap may sound appealing at first, it is actually caused by less-than-ideal conditions.  

Why Do Snails Sleep So Long?

Does A Snails Sleep Schedule Differ From Humans?

Unlike humans, snails don’t abide by the rules of night and day. Generally, snails will sleep on and off in between periods of 13 to 15 hours. Afterward, they experience a sudden jolt of energy for the next 30 hours, where they get all their snail chores done!  

How Can You Tell If a Snail Is Asleep?

It can be pretty tough to determine whether or not a snail is sleeping, considering they don’t show any obvious signs such as having their eyes closed or snoring. However, there are still a few simple ways that can help you tell whether or not a snail is sleeping:

• The shell may hang away from their body slightly
• Relaxed foot
• Tentacles appear withdrawn a little

It may be easy to assume that the gastropod is dead, but don’t jump to conclusions when you see an immobile snail in the garden — it may just be taking a power nap.
