Here you can put a standout title, something that captivates your audience

Interactivity and animation can be your best allies when it comes to creating tables, infographics, or graphs that help provide context to the information and simplify the data for your audience. We are visual beings and it is easier for us to "read" images than to read written text.

Did you know that in addition to taking advantage of our resources, you can add any visual elements you want to complement the information? Try it out using the Image or Resources menus!

With Genially templates, you can include visual resources to leave your audience amazed. You can also highlight specific phrases or data that will be etched into the memory of your audience, and even embed external content that surprises: videos, photos, audios... Whatever you want!

Describe the problem you are going to solve and, above all, the reason why your idea is interesting

Animate your content and take it to the next level

Share your idea with an image

Provide context to your topic with a subtitle

Visual content is a universal, cross-cutting language, like music. We are able to understand images from millions of years ago, even from other cultures.

• They help break the monotony
• They illustrate what you want to convey
• They allow you to synthesize content
• They are an aesthetic resource
• They tell stories on their own
• They keep the brain awake.

Maps are a great ally, use them!

Interactive visual communication enhances communication results on any topic and in any context. Before you start creating, it is advisable to spend a few minutes thinking about what this map tells you.

Insert an awesome video for your presentation

And use this space to describe it. Multimedia content is essential in a presentation, to leave everyone amazed. Additionally, you will synthesize the content and entertain your audience.

Conduction

Conduction happens when the body directly comes into contact with a colder surface such as ice. Heat from the body will transfer to a colder surface causing loss of thermal energy.

Convection

Convection is the transferring of heat through air or water. In a cold, windy environment there is more heat loss due to the air carrying heat from the body's surface.

Radiation

Radiation is the emitted infrared heat energy that moves from the body's surface to the surrounding environment. In a cold environment the body will radiate heat away from exposed skin.

Respiratory Heat Loss

In a cold environment and breathing in the cold air causes the respiratory system to warm and humidify the air before it gets to the lungs. This causes heat loss from the body.

Knowing and understanding these mechanisms of heat loss in a cold environment is very important for athletes to effectively prepare for the frigid landscape. Through these processes the body lets our thermal energy in order to maintain a stable internal temp.
