Hurumanu 5: Math Summary

In this part of the hurumanu, math, we began to look at tesselattions, tranfering into geometry. For this we look at the angles for such shapes, how each reflect, rotate and translate. One of the first activities that we did was making our own tesselations, colouring and cutting out patterns that are of symetry. Then we look at using a site in which to help us gain better knwoledge about how geometry works. For this we use Euclidea; a site where you need to accomplish task that would require the knowledge of how each of the shapes relate into each other. Moving forward we then look at the last of our topics. Algebra has been the main focus in this part of the hurumanu for several weeks. We first look at patterns and then started into a more complex algebra that need equations. Matheletics tasks were introduced, from graphs and other algebric forms. Finally, in this week we now make a presentation about algebra that would relate into the other part of this hurumanu, science. For this we look at the Fibonacci sequence, the natures code and we continue forward into making the presentattion which we have now finished. 

I have enjoyed this huruamnu greatly, I enjoyed learning about both algebra and geometry. The geometry that is with specific point into the angles, I enjoy the math that is needed for solving such questions. I like also the complecation that is involve in algebra, the representation using letters and both the "vagueness" of using such methods.  With the Fibonacci sequence I enjoy looking at it's peculiarity, how it cconnects to most of botany, the mystery behind such sequence and its future use. 

Lemon Batteries

 Aim: To produce an electrical current using Lemons.

Material:

• Lemon
• Copper electrode
• Zinc electrode
• Copper wire
• Voltmeter

Steps:

1. Roll lemon to soften the inside. 
2. Insert the copper at a reasonable depth in the lemon.
3. Insert the zinc electrode, nail, piece in the lemon, similar to the copper.
4. Connect the voltmeter to the wires.
5. Connect the wires to the copper and zinc plates, nails, wire, onto the voltmeter.

Findings: 

1 lemon = 1v

2 lemon = 1.8v

3 lemon = 2v

Volt changes, when the arrangement of the placement where the copper and zinc is put in.

 

Hurumanu 5: Week 11 - Circuits

We further continued our learning of electricity, volts, voltage and amps. By such in this hurumanu, we created diagrams, the diagrams each contains different types and ways in which a circuit can be made. For this, we created 4 circuits with half being series and the others parallel. In a series circuit, all are connected together in a single path. If a bulb has exploded the others will be affected by this and as such, they will all turn off. However, in a parallel, the electricity is separated and thus this will result in the disturbance of the other bulbs if one has exploded.

Huruamnu 5: Circuits and Electricity

d Series Circuit:

1. How many apms in the circuit? 5 amps
2. How many amps at A1 and A2? 5 amps
3.  How many amps in 1,2,3,4? 5 amps

Parallel Circuits:

1. A1 and A2 contain two amps
2. A1 has 1.5 amps A2 has 1.5.
3. A1 has 12 amps, A2  has 3 apms and A3 has also 3 amps. 

In a series cicuit, there is only one path for the current to take. The diagram above shows a battery (consisting of 2 cells) connectesd to two bulbs wired in sereis. If one of the bulbs in the cicuit (blows), then the cicuit will be open and current will stop flowing.

In a parallel cicuit, the current has more thann one way of moving around the cicuit. If one of the bulbs fails (blows), the other one will still have a current through it and will still glow.

Hurumanu 5: Science

This week, in Hurumanu 5, science. We continued to learn further about energy, in this we learn the many different types of energy. What kinds of energy can we see? Some notable examples that we use and see every day, is light energy, which enables us to see, energy--specifically light from the sun. Kinetic energy the energy released when we do any movement, walking, sprinting, running, throwing are all releasing kinetic energy. Energy is all around us, it only takes a small observation to see and realize the many types of energy that are present.

Science: Lab Safety

In this hurumanu, we are beginning to at last starting to learn. However, like other subjects and the previous learning about the science we first need to review how much danger lab could pose. We have now begun to look at safety that for our own benefit as well as for the benefit of others in this class. The rules of the lab were mostly created by us, which uses taht lab, though there are some exceptions. The rules as mentioned are to keep us away from harm, to take there are many hazards in the laboratory and thus we need these rules for our safety.

In this class, we have also started into looking at some words that we need to know about which are the following:

Safety: To protect yourself and or others from harm and danger.

Hazardous: When an object can be dangerous to you or has the potential to harm you.

Meniscus: The curved side of a liquid when it is in a container, or surrounded by solid.

Rules:

1. Put your bags under your desks.
2. Do not run inside the laboratory.
3. Do not play with the equipment.
4. Wear safety glass when are in an experiment that includes fire.
5. Do not eat and or drink in a lab.
