What is an enzyme?

Enyzmes are biological                      . They                     the rate of a reaction without being used up in the process. Each enzyme is                      to one substrate as only that substrate's shape fits the enzyme's                                .

What happens to an enzyme at high temperatures?

Within 4 years, the areas between the trenches completely changed. It became a no man's land. Why do you think the area was called this?

Vermin such as rats and lice were a huge annoyance for the soldiers. Some spent time in between battles chasing and killing them.

Guarding the trench was an important responsibility and there were severe penalties for falling asleep! Why do you think this was the case?

Soldiers often wrote diaries about life at war as well as letters home to their families. Many have been preserved and act as valuable sources of information.

Not only did dogs keep soldiers company, they also delivered messages and even groceries between the trenches.

360° video of trenches in WW1

While checking out the video, you can look in all directions.

Give it a try!

Soldiers took it in turns to sleep during the day as the night was a good time to spy on the enemies. 

With a periscope, soldiers were able to see the enemy without risking their lives. A periscope works with 2 lenses by reflecting images from the outside down through the pipe.

Trenches were made in zigzag lines. Why do you think they were built like this?

Tangled barbed-wire was used to prevent the enemy from approaching the trench to attack.

Buckle up, class, because we're blasting off to learn about life on the International Space Station (ISS)! Imagine a massive metal spacecraft zooming around Earth at breakneck speed, completing a whole trip around our planet every hour and a half! That's the ISS, a giant science lab in space where astronauts live and work. It's kind of like a space apartment with rooms for sleeping, eating, exercising, and even conducting mind-blowing experiments!

The coolest part? There's almost no gravity up there, unlike here on Earth. That means astronauts float around like weightless superheroes! They use special velcro patches to stick themselves to the walls and have to squeeze their food out of pouches and slurp their drinks through straws. To see our beautiful planet, they peek through gigantic windows called cupolas, offering breathtaking views of Earth. Living on the ISS sounds like an out-of-this-world adventure, wouldn't you agree?

 An invisible force that pulls everything towards the ground here on Earth. In space, gravity is much weaker, allowing things to float freely.

A scientific activity designed to test something and learn new information. Astronauts on the ISS conduct all sorts of experiments to help us understand space travel and life beyond Earth.
