At March 7

Jon dancing because with collected data that we needed

In March, the ph was about 6.9 and the turbidity of water had an average amount of 185.

I notice that our data had decreased and increased from September and November and January.

Next time we collect data, I wonder the ph and the turbidity would increase because the data has been increasing for 2 months.

In Project Collisions, I am creating a system to deliver foods to the peoples who can’t get foods easily. For example, peoples in the battle area, by drones. The drone will release the package from a height of up to 10 meters, and my job as an engineer is to develop a solution so that the box is protected in its fall.

For Drop 0, a package with the dimensions of was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold A hamburger, A drink and some fruits inside, items are organized like this:

The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.

Procedure

1. Person A folds the parachute twice. And bring it up.
2. Make sure Person A is carrying their computer to the drop area, person B is preparing for the drop and person C is waiting down to pick up and record the data after the package is dropped.
3. Person A Check the product, check if there is anything that’s not stable or need to finalize. (Checking for last minute completing)
4. Person C check if the Logger Pro is plugged into the computer and start video recording.
5. Person A goes up to the dropping area and measure the high for the drop. Person A aim for the force plate.
6. Person B make sure the product is at the needed height.
7. Wait for the video person B to start the video and the data recording.
8. Person B judges if the drop will be safe and if it is, send a signal to person A for the drop.
9. Make sure there is one person C waiting down to pick up the package and collect data.
10. Drop the package in a safe position.
11. Sit down together as a team, look over the package and the data.
12. Compare with what we had before.
13. Look at the mistakes and find out a solution then fix it.

*If successful:

• Encourage each other and keep the product safe in place.

*If not successful:

• Encourage each other, compare the data with drops before, look at the mistake, find a solution, fix the error. Collect data.

During the drops, I noticed that Sometimes, Our package will twist and also hit in the corner. So I thought that it was a big problem that we needed to fix. The following data was collected:

The average time it took for our package to fall the 5 meters was 1 Second. Using LoggerPro, we plotted out the fall of the package.

Our package got faster and faster.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was It hit the target, but it bounced and half a meter. As a project metric for accuracy, we want our project to 40~50cm.

The average force on impact was 98. As a project metric, our group has decided to make a parachute to 40

Summary: Project Metrics

Our team has determined that the three most important criteria to design towards are Accuracy, soft landing, and food in shape. Below, each metric is described, and the goals were determined by data from Drop 0.

• Soft landing land with force about 30~50 with is about 40% difference.
• Have accuracy and make it land on the force plate.
• Food is separated.

Our group is now building the first prototype. I hope that we have the things above.

In FA-7 science class, we investigated the size of an egg. At first, we saw this video on youtube about an egg changing its volume. In that video that we saw an egg that was put into vinegar for 24 hours and put into water and corn syrup also for 24 hours. And I was amazed by it. The size of the egg changed so much that I could see that the edges changed. And after looking at this video, we draw a simple model.

After drawing the model, we saw the video several times, and our group wrote a prestige. We also thought of independent variable and dependent variable. There were time, temperature, and size of the nicer was the thing that we came up with of, the nicer was the thing that we came up with.

In our first test, we used water for A, syrup for B, liquid soap for the C

1st experiment

Our groups understand that…

1. Sugar molecules can go inside of this egg. Vinegar melted the egg’s shell. But not big enough for the sugar molecules.

2.low density moves to higher density. So the egg got bigger/lower until the density is averaged out.

After in the vinegar

In my story, Justin faces problems between inequalities. Justin and his father is at one of the lowest places on society. Their job is to look for new thing on the ocean because sea level raised in a rapid speed, scientists wasn’t prepared for the resources. And Justin doesn’t get enough education for some knowledge.sustainable development goals 4, 10 explains Quality education and Reduced inequalities. With this problem, UN is also solving it. So, I believe that we (looking form the future) tried our best to do so.
