How do we affect our watershed?

You may have seen these plaques near street drains. They remind us that what we leave behind eventually will go to the Chesapeake Bay. It is important not to litter or pollute because it can affect the animals who depend on water, including humans!

Reflection Activity:

In your notebook brainstorm ideas about how you can help protect our watersheds.

What is a watershed? 

A watershed is an area of land where all the water above and below ground flows to the same place.

Can you guess which watershed Hartwood is a part of?

We are part of the Chesapeake Bay watershed and so are parts of six other states.

It looks like this......

All of this blue water eventually travels to the Chesapeake Bay.

Warm and Cold Fronts

We have learned about the types of precipitation and the clouds that create them.  But that doesn't really explain HOW the precipitation is created in the atmosphere.

Today we are going to explore air pressure and warm and cold fronts. Click on the link that that says Weather Maps.  It will take you to a website that explains what they are with a great visual picture.

When you are finished draw a picture of a cold front using red and blue crayons if you have them at home.  If not, write the words red and blue next to them.

You can also draw a picture of a warm front.  Remember...drawing helps you visualize your learning!

Weather Data

Have you ever wondered what the weather will be tomorrow? next week? or next year?

This is something that weather forecasters wonder about too. 

Weather forecasters look at many different variables:

Temperature is measured using a thermometer.

Wind speed is measured using an anemometer.

Rainfall amounts can be measured using a rain gauge.

Air pressure can be measured using a barometer.

How does the weather forecaster know how to predict the weather?

Click here for the video to watch tonight.

When you are done, answer the question on your reflection sheet.

Cloud Formation

Have you ever wondered what the names are for the clouds in the sky?  And what types of precipitation do they create any way?  This video will help you learn more about three of the main types of clouds that you need to know:

Cirrus clouds


cumulus clouds

Watch and learn.....

Looking for more???  
Here is a fun way to practice information about what types of precipitation falls from different cloud types. .
