Fill in the blanks:
Maybe you recycle cans, glass and paper. Do you know that nature recycles, too? One of the things nature (1)...recycles... is water.Water goes from oceans, lakes and river into the air. Water falls from the air as (2)...rain... or snow. Rain and snow eventually find their way back to the ocean. Nature's recycling program for water is (3)...called... the water cycle.
The water cycle has 4 stages: storage, evaporation, precipitation and runoff. Water on the Earth gets stored (4)...in... oceans, lakes, rivers, ice and even underground. Water goes from storage into the atmosphere by a process called evaporation. When water evaporates, it changes from a liquid (5)...into... a gas, called water vapor. Water vapor goes up into (6)...the... atmosphere. Water returns to the Earth as precipitation in rain or snow by changing into drops of water (7)...when... the air gets cold enough. Clouds are collections (8)...of... water droplets. Most precipitation falls into the oceans and go right back into storage.
Water that falls on land always flows from (9)...higher... places to lower ones. This flow is called runoff. Water from land flows into streams. Streams join together to make (10)...rivers... and eventually the water flows into storage in the oceans.

Vấn đề 8. Một container có hình khối có kích thước như trong hình. Các thùng có 54 lít nước trong đó. Bình muốn biết một xô đầy chứa bao nhiêu lít nước , do đó, ông đổ cả xô nước vào container và thấy rằng mức độ của nước tại 7 8 là chiều cao của container. Từ đó, ông có thể tính toán bao nhiêu lít nước một xô đầy chứa . Nếu container rỗng , bao nhiêu xô nước phải Bình đổ vào các container để làm cho nó đầy đủ?

To solve this problem, let's break it down step by step.
Step 1: Calculate the volume of the cuboid container.
The volume of a cuboid is given by the formula:
Volume = Length × Width × Height
Given:
Length = 12 meters
Width = 6 meters
Height = 4 meters
Volume = 12 × 6 × 4 = 288 cubic meters
Step 2: Convert the volume to liters.
Since 1 cubic meter = 1000 liters, we have:
Volume = 288 × 1000 = 288,000 liters
Step 3: Determine the volume of water after pouring a full bucket.
The water level after pouring the bucket is at 7/8 the height of the container, which means the volume of water is 7/8 of the volume of the container.
Volume of water = (7/8) × 288,000 liters = 252,000 liters
Step 4: Calculate the volume of water in one bucket.
Since initially, there were 54 liters in the container and after pouring the bucket, there were 252,000 liters, the volume of water in one bucket can be found by subtracting the initial volume from the final volume.
Volume of water in one bucket = 252,000 liters - 54 liters = 251,946 liters
Step 5: Determine how many buckets are needed to fill the container.
To find out how many buckets are needed to fill the container, divide the volume of the container by the volume of water in one bucket.
Number of buckets needed = 288,000 liters / 251,946 liters ≈ 1.144
Since Bình cannot pour a fraction of a bucket, he would need to pour 2 buckets of water to fill the container completely.

Read the passage carefully, and decide whether the sentences are True or False
Our school has a model club. The members of the club try to make water rockets. The students taking part in the club love discovering new things and learning science subjects. A water rocket doesn't cost you much. You can use the things you have used such as empty bottles, old types of bicycles. The model has two main parts : the base and the rocket. The pump in the base is made up of water pipes and it can increase the pressure of water. The rocket made from empty bottles should have blades in its tail and a pointed head. These parts help the water go in the correct path as the membershave planned. When we use the pump to incease the pressure of water, the rocket will take off and fly into the air. our school club has just won the first prize on making water rockets.
1. The members of the model club have a love of science.
=> T
