Revenge on the Vegies

We did "Which vegetable burns the quickest?" for our science fair experiment. We decided to do this experiment because we aren't humongous fans of vegetables and we just thought we'd try and get them back for all of the times we have been forced to eat them.

Yes, we're talking to you broccoli! But we actually didn't use broccoli in our experiment. All of the vegetables that we burnt were: Onion, cucumber, capsicum, avocado, carrot, lettuce, eggplant, pumpkin and potato. We burnt them in a pan over flames. (No oil in the pan.)

The results (These are the order in which they burnt. From 1st burnt being the one that burn the quickest and 9th burnt being the one that took the longest amount of time to burn):

1st Burnt = Lettuce
2nd Burnt = Capsicum
3rd Burnt = Eggplant
4th Burnt = Onion
5ht Burnt = Cucumber
6th Burnt = Avocado
7th Burnt = Potato
8th Burnt = Carrot
9th Burnt = Pumpkin

We found out a lot of things including that lettuce was the vegetable that took the shortest amount of time to burn and that pumpkin took the longest amount of time to burn. We found out that capsicum and eggplant skins are similar than we thought they were. And we also learnt that what is inside the avocado is oil, not water or juice.

our partnership was one thing that worked very well. We both co-operated and helped each other. Another thing that worked well, and payed off, was how the science board looked. We received a lot of compliments about the look and colour of our science fair board. And people could tell how much effort we put in to make it look all flash and pretty.

We found that getting everything done on time was quite a challenge. We only had a few days to run the tests, type up the information and border it and tape it onto the board. But it was worth it in the end.

Science Fair


This term we have been working on the science fair.We split into groups and decided on what we will do our project on.We decided to do a test on model boats. After we tested them we found out that Owens boat design worked the best in wind, Dylan's boat design work best in waves and Jades boat design work best in calm waters for a long time.

Black, White Or In-Between?


For the last few weeks, the whole of Mapua school has been doing science experiments for the annual Nelson Science Fair. Here is our story:


We (Kelly, Eva and Emma) decided on doing our experiment on chocolate!!! We surfed the net looking for some ideas and found the one we wanted: Which cadbury chocolate flavour is the best to use when modeling chocolate?

Once we had our question, we started to think of how we would judge the chocolates and what method we would use. We came up with three categories for testing- Fastest to Melt, Fastest to Set and Best Looking.

We then decided that our method would be to put a small plastic bowl in a bigger plastic bowl fill of boiling water and time how long it takes the chocolate to melt. We then would put the melted chocolate into the chosen moulds, place it in the freezer and time how long it takes to set. And finally, we would judge the appearance of the finished chocolate by looking at the outside, and then cutting it in half and looking at the inside. We rated the appearance out of 15.


We found the averages of all the tests (we did 3 tests for each chocolate in each category)

and then figured out the overall winner. The winner was dark chocolate, so if you are ever modeling chocolate, then use dark because it is the best thing when it comes to the easiest and best looking chocolates!


Although we didn’t make it into the Nelson Science Fair, we had a great time working in our experiment, and we definitely enjoyed eating it!

TO RISE OR NOT TO RISE?


We have spent this term completing some science boards that we displayed at the school science fair last Friday with the winnners going through to Stoke Science Fair which is held at the stoke Memorial Hall and all the schools around the region compete in. We did our science display board about which type of yeast makes bread rise the most. We had three different types of yeast Edmonds Surebake, Edmonds Active and Tasti yeast. The best yeast turned out to be the Edmonds Surebake the second best was Edmonds Active and in third place was the Tasti which turned out not very nice and it didn't look nice either. We found it a bit difficult having a limited time to complete our experiment but we managed to do it and only missed out by one point on getting through to the Stoke Science Fair.

Who needs soil?


For the past few weeks Room 11 has been working on the Mapua School Science Fair. We got into groups of three or two and each worked on our chosen science project. Our group, Emily, Jasmin and Eden worked on the project 'Who needs soil?'. Our question was 'What substance can watercress grow in other than soil?' and our hard work paid off, our group got into the Nelson Science Fair! We were so proud of our effort and determination, (in the class we were the second ones to finish!).

Some Like It Hot!

About 5 weeks ago laura and I decided on what we were going to do for science fair. Our amazing idea was What temperature out of boiling water at 9o'c warm water at 50'c room temperature at 30'c and ice cold at 10'c would keep a cut flower alive for the longest. Laura and I decided on this experiment because we thought it would be useful to know if there would be any way of preserving cut flower for longer. For the experiment we had 12 plastic cups 3 for temperature, we put 1/2 cup of water into each cup and then put 1 daffodil into each , we then changed the water every day at 10.20 am to heat it u or cool it down again. The results were that the boiling water killed the flowers within 4 days, the warm water killed the flowers within 5 days and so did the room temperature but the ice cold water kept the flowers almost perfect until the experiment was over. We found out that the reason the boiling water, warm and room temperature killed the flowers more quickly was because it excites the oxogen and lets it out while the waters boiling so there is not enough oxogen for the plant to survive. Laura and I think that we did quite well on our project and we really want to find out more about why there is not as much oxogen ing boiling water as cold. BUt overall Laura and I had a lot of fun doing our experiment and we can't wait until next time

To Glow Or Not To Glow

For the past couple of weeks Mapua School has been frantically getting ready for the Science Fair Expo day on Friday 9th September. In rooms 2,3,4 and 14 the classes have each entered a entry for the Mapua School Science Fair (MSSF). In the rest of the classrooms some friends were pair up in groups of 2's, 3's and 4's. Only eleven groups could get into the Nelson Science Fair.

Max and Isaac's science investigation starts here:


Our science fair investigation was about if a normal light would charge electrons more than a red light. To carry out the experiments we set up a light (one was normal and one was red) in a box and had a video camera filming the glow in the dark stars to see the reaction. We left the camera filming for about 2 and a 1/2 hours; After the 2 and a 1/2 hour we would
check the video on the video camera.


Here is a photo of us with our finished science board:



Science fair



Last Friday, 2011 science fair took place at Mapua school, after long weeks of hard work our science fair project came together. We came to the idea of can sugar beat fertiliser at growing plants because we thought it would be a good idea so that farmers can mass produce their crops at a cheaper cost, and we finally started our testing. After one week we had the results as we thought the fertiliser won but the sugar feed plants were tastier. We put lots of effort into our project and in the end it came to us not getting into the nelson fair and a chance to win some money. By Flynn & Jake

Feel it burn

This term we have been doing science which meant that we had to do a science experiment. Our experiment was what cooking oil catches on fire the fastest. We used the following oils, canola,sunflower,olive and rice-bran oil. After experimenting we found out that rice-bran oil is the safest oil, then olive oil is the second safest and then in third was canola and sunflower oil. The judges thought that we should be one of the three teams to go to the Nelson science fair.

Reding, relaxing, pjamas and fire


Flames flying, pyjamas burning and lots of typing to complete and present our science fair board. Our science fair project was " Which Pyjama fabric caught on fire the quickest. "

We tested 4 types of fabric which were polyester, nylon, satin and cotton. After we had completed 4 fair tests we discovered and average our results. The results were cotton burnt the fastest and we thought this was because cotton is a natural fibre and the thread is quite thin and soft. Satin burnt the second fastest. We thought that satin would burn the slowest because we predicted that it would just crumple up before it started burning. Nylon and polyester burnt the slowest. In our hypothesise we predict that polyester would burn the second fastest. we thought that polyester and nylon burnt the slowest because polyester is a synthetic fabric and it has a plastic type compound consisting of many different esters, blended together and formed into strings. Nylon also burnt the slowest and thought this was because nylon is also a synthetic fabric which is made of petroleum products and polymer.

We found that the most difficult stepping stones in this prosess was finishing on time, The tongs we were holding the fabric with were wonky and it was hard and getting our presentation right.

We worked together did our fair share of work and as a result of that we got placed in the top 3 out of yr 7&8 and we are now going to represent Mapua School in the Nelson science fair competition!!!
