Hello, everyone! Recently, our school has carried out a survey on some of the students’ daily environmental habits. The results show that 85% of students remember to turn off lights when leaving the room. 60% use both sides of paper, while only 45% sort waste into different bins.

In everyday life, I make it a habit to turn off the lights when leaving the room. This small action helps save a lot of electricity. If every student in our school keeps doing this, we can save lots of electricity for a classroom to use for a whole month! This also reduces carbon emissions and helps fight climate change. It’s such an easy thing to do, but it is really good for the environment.

动物园环保之举
When I visit the zoo, I always take my rubbish away or put it into the correct bins. I never leave plastic bags or bottles behind. This small action helps protect the zoo environment. Rubbish left on the ground can pollute the soil and water. Some animals might eat plastic by mistake and become sick or even die. By keeping the zoo clean, I help create a healthier home for the animals and make the zoo a more pleasant place for visitors. I believe every small action matters. If everyone does the same, we can protect the environment better.

In daily life, I have a small habit — I always check that the gas and electricity are turned off before going to bed. This is a simple action, but it helps stop fires. Fire is one of the most dangerous disasters. If we forget to turn off the gas or electric appliances, a fire may break out and cause serious losses. My habit greatly reduces the risk of fire at home and keeps my family safe. I believe everyone should develop this good habit.

Jennifer Heldmann is a planetary scientist. Her team at NASA is looking for water on the moon and Mars, which will help decide if astronauts can live in these places.
When Jennifer was 10 years old, she saw the movie Space Camp. It is about a group of kids at a space camp who were sent to space. She loved the movie and became interested in space science. When she was at college, she learnt that people once thought there was no water on the moon. Later, she and her team started sending research tasks there. The information they received suggested that water might exist on the moon. That is really exciting news for the researchers. They love to discover something new.
When their team learnt that there was some form of water on Mars, they began to wonder: Is there anything living in the water Could there be life on a planet besides the earth
They also do research in Iceland and Antarctica, through which they learn how ice and water work in cold environments. Then they can research other planets with that knowledge. They can know how water behaves on the moon and Mars because they understand how it behaves on the earth.
In Jennifer’s opinion, kids are going to be the scientists and astronauts who’ll finally discover space mysteries. It is suggested that kids who are interested in space read more books. Having face-to-face communication with scientists is also a good idea.

Imagine this: you open the door of a car that has been parked in the sun, and you feel the air inside is much hotter than outside! That “hot-car feeling” is a tiny example of the greenhouse effect(温室效应). But what exactly is the greenhouse effect and how does it happen
Scientists said that greenhouse gases are causing the earth to be warm. Urgent action should be taken to protect our planet.
To find the answers, Li Na’s group did an easy experiment. Here’s their report and let’s see what they discovered!

Steps 1. Prepare two cups filled with soil, and mark A and B on the cups.
2. Stick the thermometers in cup A and cup B.
3. Put the two cups in the sunlight for 10 minutes and record the temperatures in the two cups in A1 and B1.
4. Place the glass jar upside down over cup A and keep cup B unchanged. After 10 minutes, record the temperatures in A2 and B2.
