Predictions on the adaptations of a wild budgerigars

May26

We are doing a research project on animal adaptations on the budgerigars. We have to make predictions on what their adaptations are.

1 A budgerigar feathers are able to absorb water so they can go longer periods of time without water

2 They are brightly coloured (yellow and green) so the sun light reflects off of them and stay cooler and so they can camouflage in the more greener trees

3 They fly in big groups or flocks so they don’t get eaten by predators

4 They are able to fly for long periods of time to look for food and water

5 They eat lots of moist food to keep hydrated

Science Experiment

June22

In science, Aryaveer and I are doing a science experiment on freezing oil. Our science topic is chemistry/ changing matter. The year 5  standards is on our teachers blog and the rubric on what we are going to be assessed on is this document – Science-Experiment-Lab-Report-Rubric.

Aim: To see if the viscosity of oil will effect it from freezing and to observe if the viscosity will affect whether it is reversible and the speed.

Hypothesis/prediction: We predict that the viscosity of the oil will make the oil freeze at a very cold temperature and it will take a longer amount of time compared to the water. The viscosity is thick which will effect the way that it is freezes. It will melt slower because the thickness might take longer to get back to its original state.

This is a method download.

Observations: 

First taken out of freezer oil looks like butter

Both melting very quickly, water melting faster

Oil started melting very quickly faster than water

Oil took 22 minuets

Water took 32 minuets

Oil felt oily

Discussions: Oil is a lipids. They freeze at a very cold temperature after a long period of time because lipids can nearly stay in the same form no matter what the temperature unlike water. Lipids don’t have an significant freezing or melting point. They will slow down or stop depending on the temperature. The lipids caused the oil to freeze because our freezer was -10 degreese Celsius

Conclusion: Our prediction was that the frozen oil cubes would melt slower than the ice cubes but it did the opposite. The oil cubes melted 16 minutes faster than the oil cubes. This happened because oil is a lipid. They do not need a lot of heat to get to their back to there original state. We also predicted that the oil would freeze and it did. A future experiment we think we could do is a ice experiment we found on the internet. If you would like to look at it this is the website – ice experiment
