Introduction to Biomes
How do energy and matter flow through Biomes?

The world is mad up of many different biomes. Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions. A biome is made of many similar but smaller ecosystems. Biomes are classified by their climate and average temperature and precipitation. Ecosystems contain interactions between the living things and the nonliving things in a certain area. In an ecosystem, the plants, animals, and other organisms rely on each other and on the physical environment - soil, water, and nutrients, for example. An ecosystem is often much smaller than a biome, although the size can vary. For example, the deciduous forest is the larger biome, but a pond is an ecosystem in the biome, with many plants, animals, and non-living components.

At any given time, ecosystems may get out of balance and will adapt or change. There are many different classifications of biomes, but we will focus on five major biomes:

1) Tundra
2) Rain Forest - tropical and temperate
3) Desert
4) Grasslands - tropical and temperate
5) Aquatic - the oceans

A travel agency is trying to boost travel to different parts of the world by increasing the advertising and selling vacations for nature lovers to explore different biomes. You have been hired to make a presentation to sell a travel package for naturalists to explore and learn more about your biome!


Each team will be assigned a biome by the teacher. It is the team's job to research the biome and gather facts and information about that biome and compare it to the forest biome which you have already studied. Each member of the team will become an expert in a particular aspect of the biome. Together the team will also explore how all the different parts of the biome work together and rely on each other. Compare your biome to the deciduous forest biome.

The expert areas for each biome are:

Botanist - Plant (Flora) Expert: Your job is to explore what kinds of plants are in your biome. List 10 common plants including some of the largest, smallest, and most unusual. Pick three of the plants to learn more about. For these plants, find what animals eat them, how they interact with other plants and animals, and what adaptations (changes) they have made to live in the biome. While using the sources, find images of your plants, writing down where the picture is. You may also draw a plant.

Zoologist - Animal (Fauna) Expert: What kinds of animals are in your biome? List 10 common animals in your biome including some of the largest, smallest, and most unusual. Pick three of them to learn more about. What part of the food chain are they? What plants or other animals do they depend on? What adaptations does the animal have to live in the biome? While using the sources, find images of your animals, writing down where the picture is. You may also draw the animal.

Geographer - Map and Area Weather Expert: Learn where your biome is located on the planet. List all the continents where you find this biome. For aquatic, list the different oceans and large bodies of fresh water around the world. Find what landforms are in the biomes. Write what the climate is like in all the areas that your biome is in. Find the latitudes of the biome. How does the location and climate affect the plants and animals? Make a detailed map coloring in your biome.

Conservationist - Ecology Expert: Find the human impact on the biome and how it affects the plants and animals. What are some ways that the biome has changed because of people. Have people helped or hurt the animals and plants in the biome? Has the food chain been affected by humans? Are these things people are doing to help the animals and plants in the biome?

Your group will need to work closely together to share your information.

Putting It All Together

Answer these questions together:

How do the plants and animals interact with each other?

What is the food chain in your biome?

How does the climate and location affect what the plants and animals do?

What have humans done to change the environment of the habitat?

Forces and Motion

I Like to Move It Move It Webquest

Forces and Motion Webquest - Grade 4

What is your favorite ride at an amusement park? One of the most popular rides at any amusement park is the roller coaster. People are attracted to roller coasters because of the height, length, and speed at which roller coasters travel. Can you design a new coaster for Six Flags that will be original and creative, yet thrilling and exciting at the same time?

Watch the following video: Roller Coasters. You will need to enter the Flanders username and password.

Six Flags wants to build a new roller coaster, but needs to know what forces affect roller coasters in order to build a safe ride for its customers. You have been hired by Six Flags to research information about forces and motion, and then to come up with an idea for a new coaster. After researching, you will test your coaster design ideas on specially designed websites. When you have finalized your design, you will submit this idea with a labeled sketch or drawing.

The world is filled with motion. Some motions just happen: the Earth revolves around the Sun, snowflakes fall to the ground, waves surge across the sea.
Other motions are under our control. We walk. We pick up things. We ride our bikes. But whether the movement is a planet revolving or you playing a game, the motion happens because of force.

Just What is Force?
Force is just a fancy word for pushing or pulling. If I push on something or pull on it, then I am applying a force to it. Forces make things move or, more accurately, makes things change their motion. Two natural forces that affect most of the motion we see are the force of gravity and electromagnetic forces.
Gravity is a force that pulls objects towards each other, like a person towards the ground.
Magnetism produces a force that can either pull two magnets together or push them apart, depending on how they're lined up.

Motion is all about forces. Forces act upon an object to get it moving, or to change its motion. So how is all of this motion measured? Scientists use some terms when they look at motion. How fast an object moves, its speed or velocity , can be influenced by forces. (Note: Even though the terms 'speed' and 'velocity' are often used at the same time, they actually have different meanings.)

Mass is another big idea in motion. Mass is the amount of something there is or how much matter it contains. It is measured in grams (or kilograms). A car has a greater mass than a baseball.

What is Inertia?
Inertia is actually not a force at all, but a property that all things have because they have mass. The more mass something has the more inertia it has. You can think of inertia as a property that makes it hard to push something around.
So, if an object is moving - its inertia (mass) will tend to keep it in motion, and if something is at rest, its inertia will tend to keep it at rest.

What is Friction?
Friction is a force that holds back the movement of a sliding object. When any two things rub against each other there is friction, like your two hands rubbing together, or your skis rubbing on the snow. When you rub your hands together they get warmer because of the friction. When you are ice skating, the friction between your skate blades and the ice melts little tracks of water in the ice because of the heat it makes.
The objects sliding against each other can be solid things, or they can be gases , like friction with the air slowing down your car, or liquids, like friction with the water slowing down a boat. Air resistance is a friction between an object and the air as it moves through the air.

What is Gravity?
Gravity produces a force that pulls objects toward one another. It is the force that keeps the Earth revolving around the sun and it's what pulls you to the ground when you trip.
