Packaging materials Styrofoam peanuts Newspaper/paper Cotton Plastic Bubble Wrap Popsicle sticks Paper clips Tape Straws January 5, 2006 Look up each item and find out details about how they are used in packaging fragile items. 6

Research • Styrofoam Peanuts – Packing peanuts are one of the most common types of foam cushioning available. Packing peanuts are normally measured in terms of cubic feet. Normally bags come in sizes ranging from 5 to 20 cubic feet. Packing peanuts are mostly made from recycled polystyrene or starch and come in various shapes and sizes. Log Date: January 6, 2006 Louisville Academy Elementary School 7

Research • Newspaper – Most packaging companies will carry a line of shredded materials in addition to packaging foam. Shredded newspaper, wood, and tissue are commonly sold to do the job of the styrofoam peanut. Log Date: Louisville Academy Elementary School 8

Research • Cotton – Cotton is a white or yellow-white vegetable fiber grown anciently in both the Old and New Worlds. The fibers come from a plant, related to the hollyhock. The plant requires a warm climate with about six months of summer weather for full development. It blossoms and produces bolls or pods of cotton fibers. The chief constituent of cotton is cellulose (87 to 90 per cent). Cellulose is a solid, inert substance that is a part of plants. Log Date: Louisville Academy Elementary School 9

• Bubble Wrap Research – “Bubble Wrap manufacturing starts as polyethylene resin, in the form of beads about the size of pea gravel. The beads go into a extruder - a long cylinder with a screw inside that runs its entire length. As the screw is turned, heat builds up and the resin melts into a liquid that is squeezed out of the cylinder into two stacked sheets of clear plastic film. One layer of the film is wrapped around a drum with holes punched in it, and suction is applied drawing one web of film into the holes that form the bubbles. The second layer of film is then laminated over the first so that when the two films are joined, they stick together and trap the air in the bubbles. ” Log Date: Louisville Academy Elementary School 10

Design AS A GROUP OF TWO Log Date: Louisville Academy Elementary School 15

Technological design step 2 Designing a solution or a product – Generate ideas on possible solutions or products – Evaluate the factors that will limit or restrict the design – Determine the trade-offs Log Date: Louisville Academy Elementary School 16

Technological design step 3 Implementing the design – Build and test – Identify any problems – If necessary, redesign the solution or product to eliminate any problems Log Date: Louisville Academy Elementary School 17

Experiment Procedures 1. Gather all materials needed for the experiment. 2 a. If the egg cracks or breaks, we will mark it on the recording sheet as cracked. b. If the egg does not crack or break, we will increase the height and drop it again. We will continue this process until the egg does crack or break. 3. We will repeat this process with each student Log Date: 18

8. In the future, how do you think you are better prepared to solve technological design problems after completing this experiment? Log Date: Louisville Academy Elementary School 35

Conclusion After conducting our experiment, based on the highest average height of drop, we concluded that ________, can be used as a good source of protection for packaging of fragile item. Log Date: Louisville January 10, 2006 Academy Elementary School 36

Application Millions of fragile items are shipped across the world daily. Ensuring that these packages reach their destinations safely and undamaged is a key service measurement on how well a carrier provides service. Companies such as the United States Postal Service, Fed. Ex, DHL, and UPS provide customers with the option of selecting their preferred type of packaging product that will be used to protect their items during transit. Log Date: Louisville January 10, 2006 Academy Elementary School 37

Application There are several types of materials used to enclose the fragile item to make certain that the item is secure and able to sustain any jarring. In our scientific experiment we selected 4 of the most commonly used packaging items to determine which products does a good job of protecting the fragile shipment. From the conclusion based on the experiment results, we can make a informed decision on which packaging material to use when shipping our fragile items.

Extension Optional addition for the egg drop: Bring in one item from home to add to the items given. You will work as a group of four to combine your items and complete a new eggcraft to drop on Tuesday. Items are optional and will not deduct points from your summative grade. I will provide you with a choice of cotton balls, bubble wrap, paper, or a balloon if you are unable to bring in an item. Log Date: Louisville Academy Elementary School 40
