Fun with Venn Diagrams -Did you enjoy our Venn Diagram activity in class?  In this activity, take the Venn Diagram challenge!  See if you can figure out the rules of the Venn Diagram by placing the correct sizes, shapes, & colors into the appropriate circles.  When you think that you have finished, be sure to select the rule for each circle by selecting from the drop-down menu.  Once you have selected the appropriate rules click the "Check Rule" box to see if you were correct.  Good luck! If you enjoyed this activity, why don't you try your hand at these other math Venn Diagrams:

Even Numbers/Multiples of 5 Odd Numbers/Less than 20 Square Numbers/Odd Numbers Even Numbers/Prime Numbers

Leopards of the Night -We discovered in class that one way in which animals and insects are able to survive is by using a strategy called camouflage.  But did you realize that there is more than one kind of camouflage strategy?? In this activity, you will learn about the various survival strategies that animals and insects use.  Drag each animal over the label that best describes its survival strategy. Once you put the animal in the correct column, its name will appear.

The Disappearing Act -Why is it so difficult to see animals and insects when they lie perfectly still?  Oftentimes, it's not just their colors that blend in with the environment.  This activity will help explain why.

The Hidden Animals Game -Click on a particular animal and see if you can find this animal in each picture.  Some of the pictures are easy, but don't be fooled!  Some pictures are really challenging!

Bird Beak Adaptation Game -Do you remember playing the bird beak adaptation activity in class?  This game will really test your ability to figure out what type of beak works best for different ways of feeding!  Click here for an even more challenging version of this game!

Build a Fish -We learned in class that all birds have a certain design to their beak that enables them to capture specific types of food.  But the survival strategy of having a specific body design can be applied to just about any creature out there in the world!  In this activity, see if you can design a fish with the right adaptations to survive. Try different combinations and see which ones work together.

Mare's Build a Fish -Here is another activity that puts you in charge of designing a fish that best suits its environment.  What I particularly like about this activity, is that it lets you choose from 6 different environments.  Be sure to click on "instructions" before playing this activity.

The Food Chain Game  -This activity starts out REALLY easy and then gets more difficult as you go along.  See if you can correctly place each organism in the correct spot for each food chain.

Producers, Consumers, & Decomposers  -All living things need energy in order to survive.  Play this activity to learn how organisms can be classified by how they obtain their energy.

Carnivore, Herbivore, or Omnivore Part 1 -As you learned in the activity above, organisms that do not make their food directly from the Sun's energy are called consumers.  Consumers have different names based on the type of diet that they eat.  Click on this activity to learn more!

Carnivore, Herbivore, or Omnivore Part 2 -Once you've played the game above, let's see how you do with the selections of animals in this second game!

Fun with Food Webs -See if you can put all of the plants and animals in the correct spots for three different types of food webs- meadow, arctic, & pond habitats.

Build a Food Web -In this activity, your job is to build a food web.  Move each arrow from the predator and place it directly over what it eats.  If you are correct, the arrow will lock into place.  HINT: Feel free to move the pictures around on the screen so that you can easily see all of the feeding relationships!

Interdependence & Adaptation -The first thing you will need to do in this activity is select all of the living organisms in this forest habitat.  Be sure to click on the magnifying lens to learn more about each living organism.  Then click on "Sorter 1" to place each of those living organisms into a food web.  When you have finished "Sorter 1," then move onto "Sorter 2."

Make an Ocean Food Web -In third grade, you got a chance to learn about ocean habitats when you took your field trip to Sandy Hook.  In this activity, see if you can correctly place each marine organism in its feeding level in a giant ocean food web.  Be sure to use the hints and pay careful attention to the arrows drawn in the food web.  For best results, start by determining what producers belong at the bottom of the food web and work your way up from there!

Food Chain Reaction -A lot of people don't realize just how much the survival of each plant and animal affects the balance of a food web.  Play this game to learn more.

How Wolves Change Rivers -In 1995, the US Fish and Wildlife services reintroduced wolves back into Yellowstone National Park.  This fascinating short film explores how the reintroduction of wolves has had a far-reaching impact, not just on the entire ecosystem of Yellowstone, but even on the land and rivers themselves.

Variation of Life -In this activity, see if you can correctly classify different living creatures by a whole series of questions that they provide you with.
