How to make a catapult

What was the activity?

The activity was to make a catapult that works.

What is a catapult?

A catapult is a type of machine used as a weapon to throw rocks or other things such as hot tar, that would cause damage to something else. They shot rocks to break castle walls, or pitch or hot tar to set the target on fire. Catapults use weights and levers to send the rocks or other things into the air. 

  

What happened when I tested my catapult?

When I tested my catapult it throw my projectile and it worked quite well.

Reflection of the activity. What did you enjoy/learn?

When I read about my structure I learnt that the catapult was invented by the Greeks. I also learnt a lot about how a catapult works.  

How to make a anti gravity glass.

Today's activity?

Today's activity was to build an anti gravity glass and to do a sisomo (sight sound motion)

Anti gravity glass is?

So today I have created two forces which when they come together the create enough force that they can over come gravity.

Here is my video on how to build an anti gravity glass. 

 

What happened when I tested my anti gravity glass?

Well I didn't get soaked and I didn't wet the floor so I thought that it was a very successful experiment. And the water didn't fall out so it turned out to be very anti gravity.

Reflection of the activity. What did you enjoy learn?

I learnt a lot about how gravity work and a lot of things about gravity. 

How to make a sundial

Today the experiment I did?

The experiment I did was to make a sundial and do a sisomo (sight, sound, motion)

What is a sundial is? 

A sundial is a instrument that shows the time when the sun is shining. In the olden day when digital and analog clocks didn't exist they needed something to tell them the time.

Here is my video on how to make a sundial:

 

What happened when I tested my sundial?

Well it almost showed accurate time but it showed the correct hour.

Reflection of the activity. What did you enjoy/learn?

I really enjoyed doing the activity and I learnt a lot about how a sundial works. Now I know exactly how a sundial works

How to make a Xylophone

 Today the activity I did was:

To build a xylophone and do a Sisomo ( sight, sound, motion) how to make it.

A Xylophone is:

A xylophone is a musical instrument. Most xylophones are made from various metals and woods. In xylophones there are strips of varying lengths arranged in a row from the smallest strip to the biggest strip. Because of them being different lengths, they produce different kind of musical sounds.   

Here is my video on how to make a Xylophone:

 

What happened when I tested my xylophone:

Well it was very successful and I could hear the different sounds.

Reflection of the activity. What I enjoyed/learnt:

So far I have learnt quite a lot about how a xylophone works.

I enjoyed doing this activity very much.
