2. It’s your turn to be the scientist! My goal is to figure out the reasons why the dinosaurs became extinct. I have to use my observation skills to look at the surrounding environment to find out what went wrong. 1 next

4. On the main screen there are many different areas to explore including the volcano, water, and soil. To get out your virtual microscope, click on the word. You will be able to see each area up close. Next, to pull out your virtual encyclopedia, just click on the book while you are looking under the microscope. Click on the “Scientific Findings” button and answer the question to continue. After you think you have enough information to solve the problem, click on the green “SOLVE” button! 3 4 next
7. Scientific Findings If you look at the soil, there are different layers. When the layers don’t match in a perfect line, it means that an earthquake probably occurred. Earthquakes can be caused by asteroid impacts. The ground shakes, and some plants die. Falling rocks can be dangerous. READING
12. Scientific Findings Volcanoes often erupt when an impact from an asteroid occurs. Hot ash and lava spread over the land and air during an eruption . The land around the volcano for miles becomes hot. Plants can’t survive in the intense heat. READING
17. Scientific Findings When there is a lot of smoke coming from a mountainous area, it usually means that a volcanic eruption is occurring. The ash in the smoke is very hot. When breathed in, it can damage lungs. READING
22. Scientific Findings Asteroids have “iridium” inside their rocks. When asteroids hit the ground, it creates a crater. Asteroid impacts often cause other natural disasters such as eruptions, earthquakes, and tsunamis. READING
27. READING Dinosaurs need food and water to survive. They cannot withstand high temperatures . Most dinosaurs were poor-average swimmers. Scientific Findings Dinosaurs are were very diverse. They can be small or huge, have horns or not, walk on 2 or 4 feet, and many other things. 10 11
32. Scientific Findings Large waves that go over the land are called “Tsunamis” (sue-NAH-mees). Tsunamis can be caused by impacts. Flooding the land can kill the plants. READING
37. Reading Scientific Findings Craters show where a large object crashed into the earth. Inside the crater, you have found pieces of “iridium”. Cracks in the ocean floor show that there was enough force from the asteroid to cause other natural disasters.
