STEM PROJECT 1

Waves / Project 1

I learned about some types of waves, which has " water waves, sound waves, longitudinal waves, mechanical waves, amplitude and energy, also proportional relationships."

This STEM PROJECT 1 connect to the "water waves," we talked about that the waves will gives damages if the wave frequency keep increasing. So we know many things after researching "The longer wavelengths will have lower frequencies. The coastline recedes, and the seawater advances. The distance between consecutive wave crests or troughs decreases."

Wave & ocean currents / Tides and sea level rise: Wave actions, ocean currents, high tides, sea level rise.

Storms and cyclones / Changes in climate and precipitation: Extreme weather events, precipitation patterns, droughts.

Ways to protect ocean:

Don’t build the dune building, respecting wildlife and natural dunes, avoiding litter and collecting waste, especially your own waste, avoiding cars, motorboats and jet skis.

Original design: The Liquid Spongey

This can makes our beaches has less damage also collect salt and makes sea water turn into clean water. We can sell those salt and send the clean water to the water center.

The Ocean:

The reason why we think this idea can works is because it can make economies moves. Make more water, and help the country to has less lack of water problems. When the LIQUID SPONGE is collecting (absorbing) sea water, that makes the wave frequency decrease.

STEM PROJECT 2

Interesting part of Unit 3

The signals by using hands is making me feeling fun and interested, because that's another ways to helps us interact and communicate with others, people with disabilities, and some situations that you need a secret language instead of talking. I only learned about 2 ~ 5 hands laguage before, so this time I learned how to shows the signal of every letters by showing dots and lines by use one finger, and a five sign, all by hands. Also learned how to write that secret and special signs for sentences or words.

Project 2

This STEM PROJECT two is to find a optical illusion and describe about that picture (what type of illusion it is, how it works, what did I see, real life examples). I chose a Physiological Illusion, things we see will send messages to our brain, and your senses part of the brain will send back the messages that been changed and fix to you. That makes the illusion happens even though it’s just a simple nothing wrong picture or view. It will automatic re-read and understanding it by using the pass experience, back ground, and gives you a fixed image that was be over-understanding by yourself. Like the color, size, clear. So as this picture, there's four grey line, but it seems like two dark and two bright, but actually they are all the same. In this Unit, I learned a lot about color and light, lenses, reflection and refraction, convex and concave. (also part of Unit 2 lessons)

Future Unit 3

I might want to learn more about signals, which means different kind of signals, there's digital signals, hands signals, numbers signals, and maybe there's more signals that I don't hear before and see before. So that's the one I want to see and learn more about.

FINAL REFLECTION

Question 01

Explain how resources limit the growth of a population. Give examples and explain this topic in detail using 80 - 100 words. Remember to use terms such as "population", "resource consumption", and other scientific terms. (Page 3 - 42 of the book).

Question 02

Explain what a Solar and Lunar eclipse is and why they occur using 80 - 150 words. You can also explain why we do not see these eclipses every month. Remember to use terms such as "rotation", "revolution", and other scientific terms. (Page 53 - 108 of the book).

Question 03

Please reflect on this unit and explain which part you liked the most and why. Use 80 - 100 words to answer this question.

Q1.

If a place has less or not enough resources then it will impact people to choose their human settlement, and also will makes people slowly leaving that place because there's no more surival supports anymore, like "animals, water, trees, underground materials." So when the resources limit are getting lesser then the economies systems will also fall, people stop having new life (babies) because of they need to survive first, if the resources are not enough for the people who are living and exist now, then stop growing population and having babies will save themselves or make a bigger chance for them to survive.

Q2.

Solar is when the Moon is in front of the Sun, between the Earth and the Sun, then people on the Earth won't be able to see the Sun, and the Moon will have a light circle around the Moon, and all the sunlight will be covered by Moon. Lunar is the Moon is behind the Sun, so there's no chance for people on Earth to see it, and the Sun is between the Moon and the Earth. These kinds of events happens when the circle of the galaxy of the circle of Earth rotated to a limited time then it'll have this kinds of placement and events.

Q3.

I like the Moon unit, which makes me learned a lot about what is eclipse, rotation, revolution, different kind of Moon, and also more knowledge about the relationships between Moon and the Sun. I like this unit is not because of how much I learned it's because that I love Moon, every time I looking at it I feel calm and chill, it's a very beautiful ball in the universes, it shines in a soft and peace way to talk us slowly and no stressed-mind to fall a sleep. I finally know how the Moon works, for example: " why it has so much types and change shapes, and actually it didn't change shapes, it change the out look that we see by how much sunlight does it has on it."
