science discovery challenge - dinosaurs

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.

Animals need certain things to stay alive:Food and WaterShelterPerfect Temperature Outside

When animals don’t get enough of these things, they die, and sometimes become extinct.

Dinosaurs are the same way!

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!

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.

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.

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.

Scientific Findings 8

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.

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.

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.

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.

Go back and read the encyclopedias again. They have lots of helpful information.

Make sure that you go back and read all the information. Try harder next time!

Now that you have completed the “Science Discovery Challenge”, you should know a lot more about natural disasters, and should’ve reinforce how animals become extinct.

All living things need certain things to stay alive. Dinosaurs have similar needs to animals from today.

CLASS DISCUSSION: Did all the dinosaurs become extinct? Maybe some were able to find enough food to live. Give examples of dinosaurs that are still around today.

next

Answer to discussion

Not all dinosaurs became extinct. The ones that were able to adapt to their

environment were able to survive.Some examples are: alligators, birds, and

lizards.

next

Write an short essay about the extinction of dinosaurs. Write 2 sentences about each of the following words.

VolcanoesTsunamisEarthquakesAsteroid Impacts

Answer the question, “How is the extinction of the dinosaurs similar to the extinction of animals?”

Take your essay home and study with your parents! You will have a short quiz next class!
