A week ago, we learned about cranks. Cranks are used in bikes, gas runned cars, and basically most modes of transportation. Cranks are wheels and axles connected with a connecter to make an object move. For example, they are used on trains. Have you ever seen a cartoon where a train moves past the screen? Do you remember those little turning rods that are connected to the wheels? Those are cranks in action.
A person can spit into a cup and the computer can see what kind of illness they have. The computer database will be filled with every single type of virus, and when the cup is put into the machine, within an hour or so, the computer will have found what is wrong with you.
Computer coding can include art and entertainment. When you have a bunch of lights that need to go on and off at certain times, humans can’t time exactly when to flip the switch or push the button, so people code a computer to turn the lights on and off at the right time. Another example of computer coding in art and entertainment are animated movies. They code the computer to do the motion, but the humans draw the actual pictures to create the whole movie.
What I enjoyed the most was learning that guinea pigs, rabbits and hedgehogs all ignore each other. I also enjoyed putting the garbage in the right bins.
If I see a piece of garbage is on the floor, I’ll make sure to pick it up and throw it away and I will make sure to put the garbage in the right bin.
For the past few weeks we have been pollinating our plants like an insect. What I mean is we transfer our plants pollen to another plants pistil. (the sticky part of the plant) after we planted we saw that seed pods were forming down the stem. When we acted like insects we rubbed cotton swabs on the stigma so we could get some pollen.
For our controlled our highest measurement was 11 cm and our lowest was 0 cm. Every plant was green. The most amount of leaves we’ve had so far is 10 and our lowest amount of leaves is 0. For our manipulated the highest measurement is 9 cm and our lowest measurement is 7 cm. The most amount of leaves that we counted is 20 leaves and the lowest amount of leaves is 7 leaves. All the plants were green.
I think the plants that have died are not going to come back, but I do think the ones that are healthy are going to grow fat, wide, seed pods. I also think that the healthy ones aren’t going to grow any longer, but I do think they’re going to stay healthy.
This is our blog post #2 for plants. In our controlled we are growing flowers. Some of our plants are dying. The highest plant measures 11 cm. Our lowest plant measures 6 cm long. Most of our plants are green, but the ones that are dying are brown and dark dark green. Our healthy ones are bright green and have flowers. The change with our plants since the start is that in the start we had no flowers and not even buds.
For our manipulated the highest measurement we had was 11 cm. Our lowest measurement is 7 cm. Our manipulated plant didn’t really change much ever since we put it in front of the window sill, so I guess our hypothesis was correct. Our manipulated grew a lot since the beginning of when we started to plant our seeds. The highest measurement 15cm. Our lowest measurement is 5 cm.
My group works really well together. I think that our manipulated is still growing because it still has enough sunlight and other plants can still survive without having a lamp light to depend on. It also has been watered and has good soil. Our group solved a problem our plants were wilting so we ask our teacher to give us something to support our plants. I wonder if natural sunlight is better than a lamp light?

My group’s question for our plants is: Will our plant grow if we put it on a window sill with natural sunlight? Our hypothesis is: If we put our plant in front of the window sill to get natural sunlight our plant will still grow because it will have the brightest light in the world. Our controlled plant has good soil, fertilizer, mysterious seeds, lamp light, and water. Our manipulated has natural sunlight instead of the lamp light that our controlled has.
For our plant set up we first put in some wicks that act like roots for the plant so it can soak up all the water it needs to survive. Then a layer of good soil. Then we put in a few pellets of fertilizer for our plant to make it grow. Next we we put in another layer of soil, but not filling up the cell to the top because we need to plant the seed. We plant the seed and cover it with more soil. All we need now is some patience and water.
We have been recording the plant growth since day three of our science unit. We have noticed some serious growth on our plants ever since we started to grow our anonymous plant. On the first day we started to record our plants we saw that it was ½ centimeter, 2 leaves and was green. But on the seventh day of recording the plant it was 2 centimeters, 8 leaves and was green.
Next was the manipulating part. Our first idea was to put the plant in no sunlight. But some other group ended up with that idea so instead of have having no sunlight we have “ Will our plant grow if we put it in natural sunlight? “ Our group is on our way to finding out our mysterious scientific question.

For our first track that we created we used strip magnets. There were six magnets on the track. We stacked three magnets on each side of the track. For our train we used two strip magnets. Each strip magnet was placed on each side of the train.
One problem that my group faced is that our disk magnets didn’t work so we used strip magnets. Another problem that we faced is that our track wasn’t lined up with our train so we put the strip magnets on the track closer together and IT WORKED! 😀
Our final design has a lot of strip magnets. We have two layers of strip magnets on the track and one layer of strip magnets on the train. Everything worked out because everything was lined up perfectly.
I feel really frustrated in the beginning but learning from our mistakes help us improve our train which made me feel less frustrated. We still did not succeed. But we still have improvements to make.
My group in the EDP process! Still have some trouble with the train and the track.
Technology doesn’t have to be electronic but it can be something that can be made so it can make life easier. Technology is made of anything that can make life easier.
Ice cube trays are technology because it helps mold ice into really fun shapes. Ice cube trays make life better because everyone has a fridge and no one makes ice so you can make ice at home with an ice cube tray and not take a trip to the store. An ice cube tray is small but useful it can fit in a freezer so you can make ice and have a lot
An ice cube tray is made of plastic and can be colored, rigid, light, rough and pointed.
Today was we created our maglev train on day 2. We didn’t have much success but a lot of failures. For my group’s success one side of our train levitated. For our failures one of the tracks for our train was facing the attracing side of our train. Another failure that we made was that the whole train wasn’t even levitating like it’s supposed to do. We put three disk magnets on each side of the train and three layers of strip magnets on each side of the track.
Today some things failed. First fail is that only one side of the train levitated. Another fail is that one side of the track was on the attracting side of the train. What my group learned from our fails is that the we had to flip the strip magnets on the tracks so it could repel the disk magnets on the train.
Our goal for the next design session is to make the train float and swiftly levitate across the track. Maybe our team could move on to the improve step of the EDP, but we still need to work on keeping the train levitated and levitate across the track!
A maglev train is a train that floats on a magnetic track. There are magnets on the train and track. The train floats about 10 centimeters above the track. The train can float can higher depending on how many magnets are on the track. For my group at first for the track our track only had one layer of repelling magnets so our train didn’t levitate. For our train we stacked disk magnets on the bottom of the train and the train levitated!
Today on the tracks we put two srtip magnets on the sides of our tracks and for our train we put disk magnets on each side to. With a few tweaks and a lot of tape our Maglev train worked. Now the moment of truth, with the power of one little tiny shove the train should float across the track and do what it’s supposed to do did it work?… we had to do something but time was almost done and I had figured out the problem. It was that there was nothing that was attracting the train towards it.
I think my group is cool we’re working together and talking about our ideas. It is a fun activity to do with friends and other classmates to get to know each other. We are working everything out and fidgeting with our magnets so it repels or attracts together. I really like my group.
