Exciting Trip to the Dinosaur Museum!

We are pleased to inform you about an upcoming trip to the Dinosaur Museum.

✿ Date: Next Friday

✿ Time: Departure from school (1) _______ 9:00 a.m.

This trip will provide an excellent opportunity to (2) _______ fascinating dinosaur fossils and learn about their history. Kindly remember to bring (3) _______ packed lunch, comfortable shoes, and a water bottle.

For any further inquiries or permission details, please contact your teacher.

We look forward to an educational and (4) _______ experience!

Scientists have found that insects and spiders know how (1) _______ healthy food. They studied a beetle and two types of spiders, all of which are predators, meaning they hunt and eat other animals. First, the insects were fed (2) _______ meals: some ate food high in fat, while others ate food high in protein.

Next, the scientists let the insects choose (3) _______ food. All of them picked food that gave them the (4) _______ they had missed in their previous meal. The beetles and spiders that ate high-protein food chose high-fat prey (5) _______ those that ate high-fat food picked high-protein prey. This shows that even small creatures like insects and spiders are careful about what they eat.

The Earth spins once every 23.9 hours and takes 365.25 days to complete a full (1) _______ around the Sun. Since our calendar year is 365 days, the extra 0.25 days each year adds up. To fix this, we add an extra day (2) _______ the calendar every four years. This day is called a leap day, and the year it happens is called a leap year.

The Earth's (3) _______ is tilted at 23.4 degrees. This tilt causes the seasons. When the northern part of Earth is tilted toward the Sun, (4) _______ gets more sunlight, so it is summer there. At the same time, the southern part is tilted away, so it is winter. Six months later, it is (5) _______ way around. During spring and autumn, both hemispheres receive about the same amount of sunlight, (6) _______ makes the temperatures milder and more balanced. This tilt and orbit together create our seasons.

1. The oceans of the Earth cover approximately 70% of the planet's surface and hold about 97% of its water. They are home to a wide variety of life, including thousands, or even millions, of different species of animals and plants. The oceans are essential in regulating the Earth's climate by distributing heat across the planet. Without the oceans, the Earth's hot areas would become hotter, and the cold areas would become colder.

2. Human activities have negatively impacted the oceans. The release of greenhouse gases into the atmosphere has caused the oceans to warm, which can lead to changes in the Earth's climate. Additionally, pollution from land, such as litter and oil spills, often finds its way into the oceans, harming marine life. It is important that we take steps to protect the oceans, as they are vital for sustaining life on Earth.

1. The northern grasslands of the United States, also called prairies, extend from the Dakotas to the Rocky Mountains. Researchers are discovering that these grasslands can help reduce the effects of climate change caused by global warming.

2. Unlike trees, which have roots underground and most of their structure above ground, grasses in prairies have long roots that go deep into the soil. When wildfires burn trees, a lot of carbon from the trees is released into the air. However, less carbon dioxide is given off during wildfires because grasses' deep roots store carbon dioxide in the soil.

3. The prairies are home to many types of grasses and flowers, such as western wheatgrass, blue grama, and switchgrass. These plants grow with flowers like purple coneflower, hairy sunflower, and bladderpod. This variety of plants is important because it provides food for pollinators like insects and bats. The prairies also support special birds, such as the sage-grouse and burrowing owl, and mammals like prairie dogs, elk, and pronghorn.
