How does this activity model the formation of raindrops? Key Concept Do you think other matter moves through the environment? Explain your answer. NOTE: There is no empty square in the puzzle between the words of two-word terms. How does matter move in ecosystems? Many types of are used over and over again in the environment. The way water and gases move through ecosystems and are used over and over is called a n. The path water follows as it moves from Earth through the and back to Earth is called the water cycle.
The three processes involved in the water cycle are evaporation, condensation, and.
Water changes from a liquid to a gas during the process of. Rain, snow, sleet, and hail are examples of. The Nitrogen Cycle 1. Nitrogen is an important element inwhich all organisms need to survive.

Sample student answer: No, the numbers of atoms on the reactants side and the products side do not match up. On the reactants side, there are one carbon atom, four hydrogen atoms, and two oxygen atoms.
On the products side, there are one carbon atom, two hydrogen atoms, and three oxygen atoms. Internal combustion engine vehicles. Tailpipe emissions include carbon monoxide, carbon dioxide, nitrous oxides, sulfuric acids, and water.
Hydrogen fuel cell vehicles can cause an increase in greenhouse gases and atmospheric pollutants like internal combustion engine vehicles do if the method of producing hydrogen does not rely on "clean" energy sources such as wind or solar power.

Since student experiments will vary, consider grading using a rubric or have students evaluate themselves using a rubric of their own design. A sample rubric can be found on p of this guide. Identify areas of physical and chemical changes in food. Include labels connected by lines to parts of the diagram.

Cities contain things such as schools and stores that enable them to function on their own. Many cities together make up another level of organization. Procedure 1. Read and complete a lab safety form. Cut out the City, Continent, Country, 2. Using a metric ruler and scissors, County, and State labels your teacher gives you. Use a different color for each square. Stack the squares from largest to 5. Use a glue stick to attach the City label to the smallest square.
Sort the remaining labels from smallest to largest, and glue to the corresponding square. Think About This 1. What is the largest level of organization a city belongs to? Key Concept How do you think the system used to organize where people live is similar to how your body is organized? Can any part of the system function without the others? Shaded letters will not be used. Crack the code by using the clues for hints.
After you read the clues and fill in the blanks, complete the chart with the number that corresponds to each letter you have used. A large animal is composed of trillions of tiny working together. Unicellular Organisms 1. Unicellular organisms are or prokaryotes. A cell without a membrane-bound nucleus is a n cell. A n cell has a nucleus surrounded by a membrane and many other specialized organelles. Multicellular Organisms 1. Each type of cell in a multicellular organism has a specific job that is important to the of the organism.Category: Documents.
Directions: In the space at the left, write U next to each statement that correctly identifies unicellular organisms. Write M next to each statement that identifies multicellular organisms.
Write B next to each statement that applies to both organisms. These organisms consist of cells. Each cell must carry out all life processes. Cells are specialized and perform specific functions. These organisms can be prokaryotes or eukaryotes. These organisms are always eukaryotes. Cells in these organisms differentiate. These organisms have stem cells. These organisms have tissues. Directions: Respond to each statement on the lines provided. Use your responses above to summarize the main differences between a unicellular organism and a multicellular organism.
Compare a prokaryotic cell and a eukaryotic cell. Directions: Use the terms from the word bank to order the levels of organization from smallest to largest.
Then write a definition of each term on the lines provided. Definition: 2. Definition: 4. Definition: 5. Directions: Answer each question or respond to each statement on the lines provided. What is a stem cell? What is the process by which cells become different types of cells? Why are stem cells in an embryo important? Why are adult stem cells important? What are unspecialized cells in plants called? Where are they located? Compare the chromosomes in a skin cell to a muscle cell in the same organism.
Include an explanation of how the two types of cells can be different. Give examples of where adult stem cells are located in people. List the four main types of tissues in humans. Then explain why the stomach has all four types of tissues. List the three main types of tissues in plants.
What do the stomach and a leaf have in common? Why do multicellular organisms have more that one organ system? From a Cell to an Organism The maps, itinerary notes, and cell phone were especially helpful to have, as well as access to the video on driving in Iceland. Overall, it was a great experience, and would consider coming back in a future year, with additional destinations beyond Iceland.
The most enjoyable holiday we have been on. The Icelandic people always made us very welcome and had high standards of service. We were thrilled and have already passed along your website to friends. Thank you so much for planning such a spectacular holiday for us. We plan to return and would love to work with NV again. We've been all around the world and agree that Iceland is at the top of our favorites. Hi Erla and Bjorg, I just wanted to drop you a quick note to let you know what a wonder time we had because you did such a good job setting up our trip.
You have a beautiful country and wonderful Icelanders. Everyone was gracious, warm and welcoming. We really enjoyed the snorkeling and the boat ride. We especially enjoyed stumbling onto the festivals. While in Norourland Eystra, stayed Daeli, we saw a Icelandic singer with a wonderful voice, Egill Olafsson in some ancient ruins at night that took our breath away. And while in Grundafjordur we saw a parade of four colors with music and fun afterwards until 11:30 pm.
It was cold to us but we stuck it out. Myvatn Natural Baths were fantastic. We did not want to get out.
The people at Nordic Visitor in Iceland are terrific. The trip was well planned with good Accommodations and excellent sightseeing adventures. I would highly recommend Nordic Visitor. Also, Erla and Bjorg. Erla made all the itinerary and Bjorg greeted us at the Nordic Visitor office. Bjorg spent an hour with us happily and professionally going over everything.
Uei and I returned to the U. I just wanted to tell you how much we enjoyed our trip and appreciate everything you did for us. Especially re-booking our hotels due to the volcanic eruption. Iceland is a beautiful country and we hope to return in the future. Lots of options with complete flexibility. Communication with Erla (the travel consultant) has been fantastic.
