Writing Science Reports, Arrays and Prime Numbers

All the grade 5/6 classes assembled today in Mr Moore's room for a presentation all about how to write up a Science report. The session went for forty minutes and there was question and answer time. All of the grade 5/6 teachers presented some aspect of the presentation. Students were also shown samples of works done by students from lasts years grade 5/6 classes. They have four weeks to write up their reports. Students all have this guide which can serve as a check list in their Science books and I gave my students an additional copy to take home and keep near their computers. Students without  access to computers at home, which is a third of my class, will be given some time in class to word-process drafts they have written. 
 Here is the guide they were given:

Writing up an investigation as a scientific report

Step 1 Background /Introduction
Write a section explaining about what moulds are then...
  • Briefly outline what you are going to investigate.
  • Give a reason why the research is important and why you and other people would want to know the answer to the question

Step 2 Hypothesis
  • Your prediction(what you think) will happen.
  • Give good logical reasons to support this.
  • Refer to the information you already know

Step 3 Equipment and materials
  • A list of equipment

Step 4 Method
  • Use clear sentences to explain each step taken to set up and undertake the experiment
  • Order paragraphs so that each step is a new paragraph
  • Make sure they are in the correct order
  • Include a discussion of how you are making sure the experiment is a fair test.
  • Be clear about which variables you are controlling and how.
  • A digital photo of the equipment set up or a diagram would be useful to illustrate what you are saying.

Step 5 Results
  • You need to have kept good observations all the way through your investigation
  • Look at how you can put your observations into a table or graph
  • You may have a selection of photos or written observations

Step 6 Discussion
  • This section explains your results and gives a chance to discuss why you think certain things happened
  • You can include a section of what worked well and why
  • Discuss what didn’t work well and why
  • Think of ways you would improve the investigation if you did it again, e.g. were there variables that you could or should have controlled?
  • Suggest ways to build on from what you have done; another experiment to take the investigation further or to investigate new questions you have.

Step 7 Conclusion
  • What you have learned and why this is important to know.

Step  8 References/Cited Sources/Acknowledgements

A glossary could be included

Following this session we continued on with our arrays work started earlier in the week. This will be marked and returned to students on Monday morning.

After recess we spent thirty-five minutes completing the boundary walk of the school grounds to ensure the students knew where they can and cannot play during their recreational breaks.  It was then straight onto looking at their bread samples to make observations and to work on the bread mould unit up until lunch.  I assisted two students setting theirs up as they missed the lesson yesterday. So for them this was day 1. One pair of students found that one of their samples already had mould growth which was visible to the naked eye.



Students can access photos of their samples on the student drive. Students now all have their individual log-ons.

After lunch we did a lesson on prime numbers and looked closely at Sieve of Eratosthenes. 


We discussed instructional texts and they way they are set out. Students had to read this with care in order to sieve out the prime numbers. The solution was then displayed on the board.  

We finished the day with the second half of the story I started yesterday called The Sorcerer's Apprentice and looked at the use of alliteration in the book as well as a lot of new vocabulary.  I also added some Colin Thiele books to the classroom bookshelves. Nearly all the students have read Storm Boy. We will be viewing the film soon.

Mould experiments planned and set to go

Today students worked hard on planning their mould-growing experiments using bread as the food base. We discussed the idea of a fair test again and students set about making their plan and preparing their bread samples. Some are looking the effects of moisture, others are investigating the impact of preservatives, ultraviolet light and other at the differences that may eventuate between the plain, wholemeal or whole seed varieties or brands.

We also talked about how to write up a background, revisited the mould vimeo film we half-viewed the other day and looked at the information offered in four books which focused on fungi.  http://vimeo.com/20196310 Hopefully this film will run faster at your homes than at school. I have watched it three times and think it is quite a useful base of knowledge. It has an excellent part on Florey and Fleming and beneficial aspects of fungi which we haven't see at school because the download fails. It is definitely worth watching. There are also two books totally dedicated to Florey and Fleming available in the classroom for reading.

Today, Students also learnt about the use of bibliographies or cited-sources and learnt how to write up one. They have taken notes in their Science books.

Most students cut their bread samples down to 100 square centimetres so mould growth can be more easily converted to a percentage.

Throw in an assembly and a music lesson, and suddenly the day was over. A big WELL DONE to those four students who shared their reports on the book and film The Lorax. The deliveries were clear, informative and pretty much flawless.

A big thank you to all parents who came to the discussions sessions. 

Tonight's homework is to design a cover page for their investigation inserting an image and to start drafting up the background information on moulds. Some students need to think about how they are going to collect the data and record their observations on the three samples they have prepared.

"ei" and Microorganisms Jigsaw Puzzles

Today after assembly, House Meetings, Physical Education and Library students focused on their spelling. This week the letter group is "ei." Their homework tonight is to finish the spelling activities based on "ei". Eighty minutes was given in class and the unit explained.

 I also showed the students the microorganism jigsaw puzzle I made on the weekend. They will be making their own this week. Each jigsaw puzzle will have its own box, with a photo of the puzzle on the front and  an information panel about their chosen Marvellous Microorganism on the inside of the lid. We will be able to share this with our book buddies in a couple of weeks time.
