Algebra in Science

In this hurumanu, we have been learning how to solve algebra and geometry. It is really easy to solve algebra but it sometimes gets difficult when its expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division).

What I like about this Hurumanu is that we can learn but also played when all the work is finish. I also like how the teacher teaches us because it is really easy to understand.

Here Is a slide of how we proof algebra in science.

We showcased our learning of algebra by using the formula of speed. What we did was Velocity=distance / Times.  

Science Experiment, Lemon Power

This day in science is explaining to you guys what is the meaning of voltage and current. So the meaning of voltage is an electromotive force or potential difference express in volts. And the meaning for the current is the flow of charges from positive to Negative. 

Aim: To create voltage out of the lemon.

Method:

• Roll the lemon out so the inside is liquid.
• Stick a piece of zinc and copper into the lemon.
• Connect the lemon up to a voltmeter. 

Result: 

1 voltage

Closer 1 voltage

Opposite 1 voltage

Discussion: When we got the lemon we rolled the lemon so it turns it too liquidy, When we have rolled it out we have to charge these acidic particles. What happens was by rubbing the lemon this creates a current that flows. 

Conclusion: The Experiment work because it moves the voltmeter up to 1 volt, and then for all the lemon it was 2 and a half volts. 

Metal Work

 In Metalwork since last week, we have been making a dog tag from scratch on a computer, it is very easy to create it. We have finished making acrylic and the wood dog tag, we are now about to make the aluminum dog tag. 

Here is one of the examples

of the Wood dog tag:

Should cannabis be legalised?

Should Cannabis be legalized? In my opinion, Cannabis should not be legalized because it will harm the people that are using it. Some effects that will happen to you immediately when you used cannabis are sleepiness, low blood pressure, anxiety, Bloodshot eyes, and a lot more things that can harm you really bad. 

What will the effect of cannabis for a long period of time? The effects of using cannabis for the long term is your breathing will not going to be normal, you will increase the risk of having cancer on your lungs. There are a lot more things that can happen to you when you are using cannabis. 

If you are a pregnant girl and you are smoking cannabis, the Cannabis can be passed on to an unborn baby through the placenta, or to an infant in breast milk. Once that happens that will affect the baby.    

What will the effect of cannabis for a short period of time? There is a lot of things that can happen to you even though you only did it for short period of time. Here are some of the effects that will happen to you.  

• Short-term memory problems
• Severe anxiety, including the fear that one is being watched or followed (paranoia)
• Very strange behavior, seeing, hearing or smelling things that aren’t there, not being able to tell imagination from reality (psychosis)
• Panic
• Hallucinations
• Loss of sense of personal identity
• Lowered reaction time
• Increased heart rate (risk of heart attack)
• Increased risk of stroke
• Problems with coordination (impairing safe driving or playing sports)
• Sexual problems (for males)
• Up to seven times more likely to contract sexually transmitted infections
  than non-users (for females
