THIS WEEK IN SCIENCE

This week in science we learned about the water cycle, floods, drought and the atmosphere.

The water cycle:

Water in the ocean/lake/river evaporates. Then it mixes with air particles and forms a cloud (condensate). Then the clouds presipatate and let it rain. The water goes in to rivers or large bodies of water or underground and then eventually evaporates again.

Floods:

Floods can cause distruction! There is so much water that it takes a very long time to evaporate.

Drought:

Just the opposite of flood, there isn't enough water to survive. Crops animals and even people can die.

Atmosphere:

The atmosphere protects us from harmfull sun rays like uva, uvb, x-ray and infared. The layers are filled with different ammounts of gasses.

This week in science

This week in science we did the classification sheet. We classified pictures and organisms and we learned about Carolus Linaeus. He made groups of classifications.

Kingdom

Phylum

Class

Order

Family

Genus

Species

When we say something has a scientific name, we are talking about the last two classifications. Genus and Species.

We are caled homo sapiens. Our genus is homo and our species is sapiens.
