One VHS video and teacher's guide. Photosynthesis is the process by which green plants on Earth capture and store the energy of the sun. The stored energy which is eventually converted to food products by the process of photosynthesis is what living things on the Earth use to carry out all their life activities. If green plants did not carry out photosynthesis life on earth would be drastically different. Photosynthesis is therefore an essential unit in the study of Biology. The program begins by stating that photosynthesis is the process by which green plants produce food for themselves and for animals. Viewers are asked to identify the raw materials and products of photosynthesis. On the Activity Sheet students are asked to list the things which surround plants.

The phrase 'free energy' is hard to hear these days. Every electrical product we use today consumes electricity and in the end, we are left wondering how to pay bills. Renewable sources of energy have been in vogue but with time, people came to realize that even solar and wind energy has its own shortcomings.

We need a form of energy that does not require heavy production cost and can continue for long periods of time. This home generator guide tells you that such form of energy is found in magnetic power. The perpetual magnetic power generators harness the energy created when two similar ends of magnet come together and produces energy. The energy produced can light your home perpetually. These can last up to 400 years and the electricity you receive is completely "free" of cost. Yes, energy can be free these days!

The magnetic power generator does not require any third - party interference or device to run the generator and neither does it need any external resource to power it. You maybe thinking that if such energy does truly exist then why the commercial electrical companies do not harness this energy? The fact is that if they do so then how can the big corporations earn their chunk of money? If people learn to create their own free energy, then how will the commercial sector survive! It's all about business, which is why the corporate sector suppresses this form of free energy.

Magnetic energy falls neither under renewable or non - renewable form of energy because the energy is created by the magnet only and thus, it is not dependent on any outside resources. They can run indefinitely and efficiently. Your home generator guide tells you how to create such device on your own. These DIY manuals explicitly explain the whole process of harnessing magnetic power. Even a novice can understand the process and follow it perfectly.

The home generator guide explains in great detail why it is beneficial to install a magnetic power generator in your home. Not only do you save money on electricity bills but you get a device that requires less maintenance cost and can function interminably without any hiccups. Magnetic power is the future of our planet.

Almost every household has plastic containers. They could be used for storing foods or other smaller items to promote organization in the house. However, do you know that some plastics are not really recyclable than the others? Do you use plastic containers that are safe for living? Check out the shopping guide below before you decide to buy plastic containers.

First of all, you need to know the different types of plastic. Plastics are put into categories based on their resin identification code. If you buy something made of plastic, you usually can see this resin identification code on the bottom of the plastic container. It normally comes with a recycling triangle logo that indicates a number in the middle. This number is the one you should be paying attention for.

Number 1 means Polyethylene Terephthalate (PET/PETE). You find this kind of plastic in plastic bottles or disposable soft drinks. When you buy one of those, make sure you dispose it after the first time use. PET is hard to clean and it absorbs and keeps bacteria and flavors.

Number 2 means High Density Polyethylene (HDPE). You can find it in jugs and liquid detergent bottles. HDPE doesn't transmit known chemicals to your food and normally the municipal recycling program accepts it.

Number 3 means Polyvinyl Chloride (V or PVC). It can normally be found in plumbing pipes, cooking oil bottles and meat wrap. PVC contains phthalates - a sort of softeners - that mess up with hormonal development. Avoid this number 3 in your plastic container if you want to use it to store food.

Number 4 means Low Density Polyethylene (LDPE). Found in grocery bags and cling wraps, this plastic is safe and recyclable. However, there are perhaps less recycling companies that want to take containers made of LDPE.

Number 5 means Polypropylene (PP) as normally found in yoghurt cups and cloudy bottles. This type of plastic is safe and recyclable. But like LDPE, it is not an item most favored by recycling companies to manage.

Number 6 means Polystyrene (PS). If you buy a take-out coffee, you are most likely served with cups made of PS. It is not a recommended plastic type for your containers as it could leach styrene - suspected as carcinogen on human - into the food stored.

Number 7 means other types of plastic resins that are not mentioned above, mostly invented post 1987. It includes Polycarbonate (PC), Polylactide (PLA) and BPA-Free plastics. PLA is fine to use for food-based containers as it is the type of plastic that is made from renewable resources with high starch content like potatoes and sugar canes. It is unrecyclable but since it is made from plants, these plastics can be composted. On the other hand, PC and BPA-Free plastics should stay avoided. Polycarbonate is the only plastic made with Bisphenol A, a substance that has been linked to various health problems like heart disease and obesity.

Now that you know which plastic is safe to pick, which type of plastic resin should you pick for your plastic containers?
