Week 4 science blog
So far this term we have done tug a war , catapults
balloon flying , ping pong ramps , chair pulley
and basket ball bouncing for science.
I found out that if you tape up the pom-poms
they fly further and better for the catapults.
I wonder how the air makes makes the balloon zoom faster.
Week 5 science blog
This week we have done a various amount
of things but I have done ping pong ramps
and this is what I wonder and found out about it after
my learning of ping pong ramps.
I found out that the ping pong ball will go
either faster or slower if you use friction because
if you use a different material to roll it down on
it will go faster or slower.
Now I wonder what different types of
materials will make it go faster or slower.
I also found out that you use force when
you push the ball down the ramp
because if you just let it sit there it won't roll
down the ramp.
Now after my learning I wonder what different
types of ways we can use to make it roll down the ramp
without pushing it down.
Also this term I have wanted to know if you can make it
roll down the ramp in many different ways
the reason I have wanted to know this is because
it usually just goes down the same old way… down.
Now I wonder what different materials will help it go
down the ramp in many different ways and many different angles.
Overall the ramp Pippa and I made worked pretty well.
Week 6 science blog
This week I got to choose between
3 push and pull activities this week.
They were basketball bouncing, ping pong ramps
and chair pulleys.
I chose to do ping pong ramps because I was wondering
lots about the different angles and different ways
I could do it and it was fun
I made my ramp in the rm 12 end in the
kitchen by myself so that I didn't get distracted from
my task easily.
I used rulers books containers and other
On my first test run the ping pong ball just
stayed in one place when I pushed it
and so then I thought that what if there's
a different way to push it down the
touching it so I got three domino pieces and
one orange log.
I put the log behind it one domino
behind the orange log and one on each side of the
ping pong ball.
On the next test run I pushed the back domino
and it fell on the ping pong ball
and the ball went shooting down the rulers
and into the basket.
After all that working now I wonder if
force is actually pushing it down.?
Week 7 science blog
Today for catapults we had to
write down a distance chart.
What we had to do on our distance charts was
do eleven tests with one pom pom and on each test
we added one rubber band and shot it
from our catapult and then measuring
it and writing it down on our chart my
longest one was four meters which was
9/8 rubber bands.
After we've done all eleven tests
with ten bands we have to do it all over
again but with three cotton balls and
starting with one rubber band so that means
that you only do ten tests.
Overall I think that my
measuring and catapulting went
pretty well but I still need to do the rest of the
test with three pom poms.
Week 7 science blog
Today for science we had the choice of either
doing card board pulleys or golf course and
I chose to do a golf course out of the two.
I have found out that making a golf
course for me is quite hard , because I
couldn't think any ideas for my course , and
I even had to get help for ideas for my course!
I wonder that if I had a plan for my course
it would've be easier for me to build and if I
could've done it better.
Overall after today I think I could've done better in my science.
Week 8 science blog
What is force?
Force is a word for push pull gravity and friction.
The difference between push and pull is that
push is your pushing something away from you
and pull is pulling something towards you.
Gravity is something that pins you down to
the earth and if we didn't have gravity everything
would just float out into space.
Friction either makes something go faster
For example you use the force push
when you push someone on a swing
because you have to push them away
from you so that they can swing
properly and you use the force
pull when you play tug a war
because you have to pull the
rope towards you.
Forces make things accelerate.
The bigger the force, and the lighter
the object, the greater the acceleration.
An object that isn't being pushed or
pulled by a force either stays still or keeps
moving in a straight line.
To make it you will need
a rubber band, a paper clip,
tape a spoon and popsicle sticks.
First you need to tape seven popsicle
sticks together as a flat surface,
then put the paper clip around the top of the
spoon, and then tape the top of the paper clip and
a rubber band to the spoon, after that strap
the rubber band around the bottom of the
popsicle platform that you made at the start
and then tape it there and tape the end of
the spoon to the end of the popsicle platform
I have found out from my grah that the
measurements from my one cotton ball
we're more steady than the three cotton ball
I have also found out that different
catapults can shoot the same distances
even if they’re completely different to
Another thing I have found out is
that the more rubber bands you have
on your cotton ball the more it bounces
and goes a less distance.
I wonder what would've happened if I had changed it
and what the effects would’ve been.
A next step for me is making it more stable because when I
pull it back it starts to break.
