Weight | Measurement

Weight is how heavy an object or item is. The standard forms of measuring weight are tonnes (T), kilograms (kg) and grams (g). To measure these things, people often use scales or balance scale.

Estimating is an educated guess to the amount of something. If a person knows that the weight of a stick is 3 markers, then they can compare the markers on a scale. If they know the weight of the markers then they can make an estimation.

To convert kilograms to tonnes, divide the number by one thousand. To convert grams to kilograms divide by one thousand. If the measurement is 18 kg, then divide by one thousand the numbers shift to right.

Simple Machines

LI: to find information about simple machines.

Our focus for inquiry was about making labelled diagrams (information pictures) in order to understand what each simple machines are. The six simple machines are: pulley, lever, wedge, inclined plane, wheel and axle and screw. The pulley is a simple machine that is able to lift objects by pulling the rope that is attached to it. A lever can lift heavy-weight objects when someone pushes the beam down from the opposite side. The wedge can stop objects from moving. An inclined plane is a surface that has an angle on it and can make objects go up or down easily. The wheel and axle helps transfer things. A screw has the ability to pull its surroundings in as it goes into a material and stay put in it. We made an information picture for each simple machines and get a good understanding of each of them. At the end of this activity, we were able to give a breif description of each simple machine. I enjoyed this activity because I have researched about simple machines before and found it pretty easy.

Week 1 | Day 4 | Activity 3: Worth her Weight in Gold (Six Points) | Summer Learning Journey

LI: To make a travel brochure.

Today I completed the last activity for day 4. For this activity we had to make a travel brochure. Our task was to create a travel brochure for Tonga or a place that is important to ourselves. I made a travel brochure for Tonga. A brochure is a type of DLO that you use to write a lot of information. I enjoyed this activity.

Pulley | Simple Machine

LI: To learn what a pulley is.

A pulley is used for pulling heavy loads with the use of a rope and a wheel. It has a grooved rim around it. If we add more loops around it we divide the weight between the rope making it easier to finish the job. We had to list some things using a pulley. Our group had remembered the objects with a pulley from school trips.

Commenting Thread

Commenting threads are a continuous conversation that consists of greeting, feedback and an open question.

Commenting threads help to unlock more knowlegde and information about the work to the reader and establish a new understanding of their work. By answering open questions they can give more detail.

The comment thread shown below was very interesting and I learned new things about weight.

Topic 4 | Floating & Sinking

LI: to test the buoyancy of different materials.

Our focus for this week at science was about testing the buoyancy of different materials. First we discussed why some things float/sink/semi-float. Floating is the action of an object staying above water. Sinking is when something is unable to stay above water due to the density of it. Semi-float is when an object has the ability to both float and sink at the same time. We watched a video that explained what buoyancy/buoyant is. Buoyancy is the tendency of something that can float in water or a substance. 

After this, we gathered our materials and looked at the size of it, weight of it and what the object is made out of. We also made predictions on whether each object would sink or not. A prediction is an educated guess of something. Some of our objects were: cube, marble, tennis ball, rectangle block, plastic block and etc

We filled up our buckets up to 2/3 and started our experiment. My parnter and I started from the smallest objects up to the largest objects. Some of our predictions were correct. We noticed that the wood materials had the ability to semi-float. The plastic materials had the ability to float and the rubber materials could float/sink. 

I really enjoyed this experiment because it gave us the opportunity to learn about new things to do with buoyancy and sinking. One thing that I learned was that some objects have the ability to semi-float. I found this fact very interesting and cool. 

SSR Selfie | The Human Body

Today I completed the SSR Selfie can-do. The objective of the SSR Selfie can-do is to learn how to summarise or retell a text. The book I read was called: 'The Human Body' by Margaret Hynes and Andy Crisp. The book was very interesting and I learn many new things about the human body. One thing I learned was that: All the hair on your head combined can support the weight of two elephants.

Measurement | Maths

Measurement has two forms; Standard metric, imperial and non standard.

Standard metric measurement includes length, weight and volume. These are seasured in mm, c, M and km. G, kg, t. Ml and L. Measurement can also be done with non standard item as shown in the attached google presentation.

Measurment is using a range of tools to find information out about an object.
