In 4th grade students are expected to use scientific investigation and reasoning in order to make informed choices in the use and conservation of natural resources and reusing and recycling of materials such as paper, aluminum, glass, cans, and plastic as well as plan and implement descriptive investigations, including asking well-defined questions, making inferences, and selecting and using appropriate equipment or technology to answer his/her questions. The use of podcasting in this CBL process will allow students to demonstrate comprehension of recycling, reducing, and reusing natural resources, while increasing awareness regarding sustainability.
In order for members of Gruene Kids as well as other students to create their own podcast, I have also uploaded (in a separate blog post) an instructional video which demonstrates how to navigate the technology.
Did you know there are different types of energy? Coal and gas are types of energy called “fossil fuels”. This means they were made a long time ago when the dinosaurs roamed the earth. The bad thing about using this type of energy is that when they are gone…they are gone and we can never get them back.
This is where renewable energy comes in. This type of energy comes from sources like wind, water, and sun. The best part about using renewable energies is that they do not pollute our environment. The challenge we face when we use renewable energy is that we can’t store it to use later. Can you figure out what happens then when the sun is not shining or the wind is not blowing?
We bet you have seen some of this type of energy in action. Have you ever seen one of these wind turbines? 600 of these turbines create enough electricity to provide power to 140,000 houses.
This week we focused on what effect litter has on the wildlife in our oceans. Did you know that the plastic rings that hold a six pack of soda cans together can harm our sea animals? Have you ever wondered how the trash gets from land into the oceans? We did some investigating and here is a little about what we found out.
Seals, dolphins, turtles and other marine wildlife can become trapped in nets and plastic items. The objects slip around their necks and the animals cannot get free from them. As the animal grows, the netting or plastic stays attached to them causing them to choke or starve to death. We were really sad about that.
We found out that in 1987 a law was passed that made it illegal to dump plastics into the ocean. We want to know if people are not allowed to dump plastic in the ocean, why are we still having so much trouble with it ending up there anyway. What can we do to help keep it from harming more marine animals?
The Center for Marine Conservation lists the following 12 items as most frequently found in the ocean. They are nicknamed the “dirty dozen”: cigarette butts, paper pieces, plastic pieces, styrofoam, glass pieces, plastic food bags, plastic caps and lids, metal beverage cans, plastic straws, glass beverage bottles, plastic beverage bottles, and styrofoam cups.
By looking at the list, we can tell that everything is a problem, but what can we do to help reduce the amount of plastic ending up in our oceans? Is there an alternative material that could be used?
This is a website we used to help us understand these things.
