Nature's Life Cycle
Overview:
In this podcast from The Friends of Auntie Litter", the Patrol learns that one very important characteristic of all living things--plants and animals--is they carry on respiration.  They also move, reproduce, grow, and take nourishment.  Bobby Bunkle describes a food chain as he scuba dives.  Since plants and animals are so important, it's crucial to protect the environment in which they live.  The Grunge, for instance, doesn't understand that trees provide animals with oxygen and homes, so he likes to cut them down.

Scorpion Science
Overview:
Scorpions are fascinating arachnids. We have spent over 3 months handling and caring for 2 Black Emperor Scorpions. This video shows one of them feeding on a Madagascar Hissing Cockroach. We have also managed to capture our scorpion as it appears under ultraviolet light. We hope you enjoy this gross yet fascinating footage.

Venus Flytrap Feedings
Overview:
Venus flytraps are carnivores. They eat meat. These plants contain 3 trigger hairs on the roof of the trap (mouth) and 3 hairs on the bottom. When an insect or anything triggers those hairs the plant snaps shut trapping its prey. Check out the video to see this amazing natural mechanism in action. NOTE: This video does not include audio.

In an Instant: Frog Feedings
Overview:
While showing the Frogs exhibit we decided to use our high speed video camera to capture frogs feeding. These videos were shot at 600 frames per second. It is amazing to watch their movements. Also watch the tongues and the eyes. NOTE: This video does not include audio.

Water Pollution
Overview:
For this activity, stream table models are utilized. Students introduce pollutants into the sediment in the stream table. Then they introduce water into the stream table and observe the sediment and “downstream” waterway.This demonstration shows how ground pollution and upstream water pollution can be carried downstream to other bodies of water and land. The “ground” in the stream table model has been polluted with green food coloring (before the water is added). As the water passes over the polluted area, the pollution contaminates the stream, surrounding land and the larger body of water at the end of the steam. After polluted water has entered into larger bodies of water (seas, gulfs and oceans), it can be spread to other areas by the Coriolis effect. The Coriolis effect is caused by the rotation of the Earth. The effect deflects objects moving along the surface of the Earth to the right in the Northern hemisphere and to the left in the Southern hemisphere. The resulting movements can cause pollution to spread far beyond its source and affect other parts of the world.

Planet H2O- Water Supply and Demand
Overview:
In this lesson, the students are instructed to imagine that they are in control of a small country. They are shown a pitcher that contains their country’s water supply. They are then asked to make decisions on where the water should go. The students are given small containers that represent their needs and demands for water. Water is distributed from the supply pitcher for each one of their demands. About 2/3 of our water supplies goes to agriculture and food production. Two-thirds (2/3) of the water from the supply pitcher is poured into the “agriculture” container. Students then list other demands...drinking water, water for cleaning, etc. Students are then presented with other factors that will influence their supply and demand. An environmental factor, such as a drought, will mean that the affected part of the country will have an increased demand (water is distributed from the supply pitcher). A great increase in the human population in another part of the country will increase their demand as well (water is distributed from the supply pitcher). When the supply pitcher is almost empty, the topic of water scarcity arises. Water scarcity occurs when the demand for water out paces the supply and causes water shortages.

Planet H2O- Water Pollution and the Aquatic Food Chain
Overview:
Biomagnification is the accumulation of a substance up the food chain by transfer of the pollutant in smaller organisms that are food for larger organisms in the chain. It generally refers to the sequence of processes which results in higher concentrations in organisms at higher levels in the food chain (at higher trophic levels). These processes result in an organism having higher concentrations of a substance than is present in the organism’s food. There is evidence that some carnivores at the ends of longer food chains (e.g. larger fish, birds of prey, HUMANS) can then accumulate the water pollutant from eating down in the food chain. Clean fresh water is vital to life on our planet. What can happen if our waters become polluted? How can that affect us as humans if it is happening in the water and to the organisms in that water? One of the ways pollution impacts humans is through food chains. We have to remember that we are part of the environment and as a result, part of the food chain. We eat many of the aquatic organisms, fish and shellfish, which can be detrimentally affected by water pollution.
