YES!

Use your entrance ticket to answer the following questions………. How is it possible that the water in our bottles has been around for millions of years (even before dinosaurs)? What happens to rain water and water from lakes and rivers? After answering both questions, put your entrance ticket in your science folder.

For your water to have been to…. and For your water to have been drunk by….

What is a cycle?

A cycle is…… a series of steps a process things working together to make something happen

Talk about it with your group…… What are some cycles you know?

Cycles

So……. Why is it possible that a stinky skunk could have drunk my water too?

The Amount of Water on the Earth Never Changes!!! It’s the same water drank by dinosaurs, cavemen and even skunks! Water just keeps going through the same cycle over and over again The earth doesn’t ever get any new water! The water cycle includes the following steps: 1.EVAPORATION 2. CONDENSATION 3. PRECIPITATION 4. RUNOFF

During Today’s Lab……………………. You will be focusing on what happens during the water cycle.

Problem What happens to rain water and water from lakes and rivers?

Research You will be using the laptops to work together in your groups to investigate the water cycle and What happens to rain water and water from lakes and rivers?

Experiment We will be adding a hydrosphere to the “ biospheres ” we have created. Then, we will be adding two types of water: room temperature water and warm water.

Hypothesis Hypothesize what will happen in each of our biospheres.

Data Observe what happens in each of our biospheres and record your results in the data section of your packet.

Conclusion Develop a conclusion that tells what happened in your experiment and why your hypotheses is or is not correct.

WHAT QUESTIONS DOES YOUR GROUP HAVE about the water cycle? and About today ’ s problem: What happens to rain water and water from lakes and rivers? Brainstorm questions with your group and add them to your research questions in your packet

Instructions for Research Work together to answer all required questions in the research section of your packet Use the 3 required links on our homepage when your begin your research3 required links Work together to problem solve and find the information. Make sure everyone in your group is participating Record what you find in your packet

Write Your Hypotheses Make sure your Hypotheses relate to your research and today’s lesson What will happen inside your biosphere when room temperature water is added? If__________________,then______________. What will happen inside your biosphere when hot water is added? If_______________, then_________________.

Experiment 1.Let Mrs. Roffo know you are ready for the experiment. 2.Students will fill the bowl inside their 1 st biosphere with room temp water. 3. Students will seal the container with plastic wrap and place it on the towel. 4.To ensure safety, Mrs. Roffo will fill the bowl inside the 2 nd biosphere with heated water. Do not leave your group or come near the sink! 5.Mrs. Roffo will seal the container and put the container on a towel in the center of each group. 6.Observe your biospheres for 5-10 minutes. Record your observations in your data. Make sure your data is valid! Do not touch or move the biospheres!

Data Observe your biosphere for 5-10 minutes. Write about what you see happening in each of your biospheres. Draw pictures that show what is happening in each of your biospheres.

Conclusion Write a Paragraph Use the words and pictures from your data to write a paragraph that explains what happened in each of the containers. Tell why you got the results you did for each container. Answer the question: “Were my hypotheses correct, and why or why not?” Answer the essential question: What happens to rain water and water from lakes and rivers?

Lesson Closure 1 person from each group will explain what they have seen in their biospheres. Answer the following questions on your exit ticket: – How is it possible that the water from our bottles has been around for millions of years (even before dinosaurs)? – What happens to rain water and water from lakes and rivers? Hand your entrance/exit ticket in Keep your lab packet in your Science folder for tomorrow’s lesson
