“Paying it Forward” The “Pay it Forward” movement started with ripple effects of kindness many years ago. The Pay it Forward Foundation was started by Catherine Ryan Hyde in 2000. She wrote the book Pay it Forward, which was also turned into a major motion picture. Over 98 countries all over the world have already joined in this movement. Now we encourage YOU to join it. You should Pay It Forward because it is the nice thing to do. There are lots of different ways to help someone out: help someone cross the street, pay for somebody’s lunch, or offer to be someone’s partner in school. If someone does something nice for you, and you can’t repay them back, the least you can do is pay it forward, do something nice for someone else. Making a Difference In ELP, we decided to help the Humane Society by asking our families and neighbors for donations. We invited a volunteer from the Scott County Humane Society to come to Bridgeview so that we could learn more about the mission of the Humane Society and what needs they have. Mr. Porber brought his adopted dog to show how they help our community. After the visit, we designed flyers to hand out to local businesses to encourage people to adopt a pet. It’s never too late to acquire a new pet! We were able to collect a variety of donations from our families and neighbors, including: paper towels, laundry detergent, index cards, cat food, dryer sheets, glass cleaner, shoe boxes, and $100 to help the Humane Society with their expenses. People sometimes think that even if they make a difference it won't matter much but that is wrong because if you make a difference it might spark other people to make a difference, too.

In this unit in ELP, 5th grade learned about robotics. We learned that all robots have a "brain"/control center. All robots are programmable and can work on their own with at least one moveable part. They also have some sort of sensor. Machines are different, because they do not work on their own. We also learned that you will most likely not get it to work the first time. If it doesn't work, it is not the robot's fault - it is the programmer! Cubelets are cubes that link together to make a robot. Each cubelet has a different purpose, and you have to figure out which order to put them in to get the robot to do what you want it to do. Depending on how you put it in order, it will do a different task. There are three necessary parts: "think," "sense," and "act." Not all of the parts can touch the power cube, so the power flows throughout the magnetic cubes to get to the others. Check out our videos to see our processes and prototypes! The goal of this challenge is to work as a team to create a car that will travel the farthest distance while carrying weight.
"The Moving Present" - The materials we used for our car were 4 small plastic wheels, 4 blue straws for axles, 2 clear straws for the bearings, and 2 toilet paper rolls for the chassis. Our 1 variable we changed was to have longer wheels because before we had our small plastic wheels, which were rubbing on the car which caused friction. So we decided to take 2 blue small straws and cut them then tape them together and put a big clear straw over the top of the blue straws. The we added the small plastic wheels. After we re-designed we realized that the clear straw wouldn't allow our wheels to spin because it got stuck from the tape in the middle of our blue straws. Also, when we did our test with weight we added to many pennies and it made our car flip over. Perseverance may not work, but you should always keep trying. Go Moving Present!! "Candy Cane" - Our team name is Candy Cane. Our chassis is made of a toilet paper roll. It has a piggy bank penny holder, too. It is covered in string and tinfoil. It has 4 wheels with straw bearings and axles. Test 1: Our car was very successful. It went 6 feet and 2 inches. Test 2: We had too much weight in the back. It did a wheelie. Test 3: It was very successful. We put 3 pennies in the front and 3 pennies in the back. We learned that it needs to have even weight. "Team Tape" - For this challenge, we had to build a car. We could have used CDs for the wheels, but all three groups chose not to. The CDs wouldn't fit with small axles, so we decided against it. We learned about all the different parts of cars like the chassis, bearing, axles, and the wheels. Our group was called Team Tape because we kept layering tape on our vehicle. Our group had a toilet paper roll chassis, a big tube bearing, plastic wheels, and a plastic blue tube axle. Our car had aluminum foil at the ends to keep all of the pennies inside. Our car also had a penny hole at the top and string wrapped around it. We observed that the weight slowed it down and that the bearings were not straight, so we changed the bearings. This made our car go farther. Our car went the farthest with no weight. It went 3 feet and 8 inches. |
