Micro-Organisms Mouldy Bread

We found that the white bread went mouldy first, followed by the 50/50. We are still waiting for the brown bread to mould.

This is what most of the class had predicted would happen. As predicted the dirty hand went mouldy first then the clean hand and the control.

Tallest Freestanding Tower Challenge

Challenge- To build the tallest freestanding tower in 25 minutes using 20 stick of spaghetti, 1 metre of tape and 1 metre of string.

Problem-The tower has to hold a marshmallow at the top.

We used teamwork, communication, co-operation and various problem solving strategies to create the most successful tower.

The winning tower was…….41 cm tall!

The winning team 🙂

Bouncy Egg

Today we went out to bounce eggs as a continuation from our science fair last week.

Science Fair Ready

We are ready for our science fair!

We had lots of visitors and a very busy morning!

Further Yeast Investigations

Today we did an experiment, where we put different levels of yeast and sugar in bottles to see what combinations would release the most carbon dioxide and make the balloons the biggest.

Changing the amount of sugar

We found adding more sugar didn’t make a difference but adding more yeast made a big difference.

Still expanding!

The balloons are still getting bigger and everyone in the class is excited to see how big the balloons grow over the weekend.

 

Yeast Investigation

Today we did a yeast investigation, to see what temperature is the optimum condition for yeast to work. We used cold water, warm water and boiling hot water.

The sugar and the yeast have started to react and the balloons are still getting filled with carbon dioxide.  Everyone in the class are  excited to see how big the balloons grow over night!

Mouldy Bread

Today we set up an experiment to see which bread will go mouldy first.

We wanted to find out if the different types of bread would make a difference.

We also changed some of the conditions so see which variable will mould first. Wet/light, wet/dark, dry/light and dry /dark.

Watch this space!

Primary 7 Science Fair- 3 Week Homework Project

 

Over the next three weeks we are undertaking a mini science project. This science project will require you to undertake a personal inquiry into something scientific that you are interested in.

First pose a research question from an area of science that you would like to find out more about.

Next you are going to try to answer your scientific question. How are you going to answer this question? You will need to undertake some research and possibly even carry out an experiment.

Please see the attached sheet for further information.

Science Mini Project

Good luck! We hope you enjoy your Science Project and we can’t wait to set up our Science Fair on Thursday 5th March!

Biodiversity

Today we learned about biodiversity. We discussed the terminology for this topic – ecosystem, environment, habitat, producers, primary and secondary consumers, prey, predators, herbivores, carnivores and omnivores. We then looked at food chains and webs. The arrow points up the food chain showing the transfer of energy from one plant or animal to the animal eating it.

We then investigated our environment and the many ecosystems and habitats that could be found in the school. We looked for evidence of food chains and ecosystems at the banking, the scottish garden, sensory garden and around the new science garden. There are bug hotels, worm farms and ant habitats built around our school. We also found numerous insects, snails, slugs, bees, bees and little bites in leaves to show they had been eaten. We passed around the class camera recording the evidence we found.
