 Task: You have to research and present a practical science experiment to the class.  You can choose any experiment you wish as long as it has a scientific purpose.  You will also need to have an excellent understanding of your experiment so you can present it and clearly explain it to the students in the class. You will be also required to fill in an experiment sheet that explains your experiment in detail.  Everybody will be given a mark out of 30 for this assignment.  You will be awarded a mark out of 10 for each of the following:- 

1.   The experiment itself.

2.   The presentation.

3.   The experiment sheet. 

The Experiment Sheet needs to include the following points

Experiment Name:

Aim of Experiment:

Equipment Required:

Experiment Steps:

Illustrations:

Experiment Findings:

The experiments are due Monday 27th October 2008, all experiments are due on the date (No extensions). Presentations will take place during Weeks 3. Failure to hand your assignment in on the due date (Week 3 2008) will result in 0 marks.

There are lots of sites on the internet to give you ideas. But remember it is your work I want to see. If you find a great site with lots of ideas put the link in the comments section and I will share the link with everyone.

  • Brain has sound memories
  • Dolphins can hear better than other animal
  • Sound can travel through walls
  • We hear because of sound waves made by vibrations
  • The shape of our ears help us hear sounds
  • If sound bounces off a wall it’s an echo
  • Kids can hear better than adults
  • Part of our 5 senses
  • Babies can hear before they are born
  • Quick vibration make a high pitch sound and slow vibrations make a low sound.

Things we found interesting about the way the podcast was made:

  • Some people liked the jokes some thought they weren’t really funny
  • Lots of interesting infromation
  • Different music
  • Well set out with sements
  • They had a quiz, it was a little bit too easy
  • Year 3
  • They said a lot of things that people might not know
  • Took turns
  • We thought it could go for a bit longer.
  • All the different sounds there are

 

What we would do:

  • Say information about sounds that they might not know
  • Make it stand out
  • Make some quizes to test other people on their knowledge about sounds
  • Show pictures to go with the topic
  • Take turns

 

Sounds we heard:

  • Bowling balls knocking the pins
  • Dogs barking
  • Tower bells were ringing
  • Water bubbles
  • Rain pouring
  • Race cars
  • Cows mooing
  • Sheeps

We floated all these boat creations to see if they would float or sink. They had to be able to hold a lego man.

We made our boat creations from bark, leaves, sticks, vines, reeds, palm leaves and seed pods.

We filled a tub with water and placed our creations carefully to test them. We tested them in three ways:

  1. To see if they stayed afloat
  2. To see if they could stay afloat in heavy winds
  3. To see if they could stay afloat in strong wave action

We used a book to create the winds and we used our hand to stir the water and make the waves.

Our observation

Lisa’s boat made of paper bark and plain bark wrapped with leaves floated a long time and passed all three tests. Jessica’s, Alexis’s, Chenaya’s, Julian’s and Abby’s passed only two of the three tests. The rest sank immediately when placed in the water.

Our findings

We found bark’s not the best thing to use, leaves float well but when they fill with water they sink. Paper bark was the best to use because it is light and flexible, it had many layers which made it waterproof. It’s canoe like shape made it stable and harder for the water to get into. The curved design and the sides going up made it harder for the water to get in as well.
