Science With Our Buddies

To finish the last of our science experiments we gathered on the oval to watch Luca and Sammy’s rocketship. We invited our Prep buddies to observe with us.

Luca and Sammy had conducted an interesting experiment where they deconstructed the ingredients of bicarbonate soda to see if they could highlight which element caused the reaction with vinegar. They then recombined the ingredients to see how close it was to manufactured bicarbonate soda and if it would cause a similar reaction.

To read more on their experiment go to either Luca or Sammy’s  site.

To check everyone else’s experiments and reports follow the links on the Class Blog listing on the right of this page.

On the oval the boy’s rocketship initially failed to impress, although once we gave it a vigorous shake to fully mix the vinegar and bicarb everyone was entertained by the result.

Today’s Maths

Goal:

I can use displacement to measure the capacity and volume of irregularly shaped objects

New Information:

1 cm3 = 1ml  and 1 L = 1000 cm3  (show litre cube and MAB 1000 cube) you can work out the (approx.) capacity of an object in ml by working out its volume (why only approx.?- because if you are talking about what it holds, strictly speaking, some of its volume has to be used up as the ‘container walls’)

When an object is placed in water it will ‘displace’ the exact amount of water that would fit inside it

 

Formula for regular shape

 

 

Process for irregular shape

 

 

Application:

What is a Fair Test?

In today’s lesson we will be investigating what is a ‘fair test’. We will also be exploring what is its relationship to a ‘control’ and ‘variables’.

Using the link you’ll find an interactive that asks you to run some fair tests as part of your work in a plant research laboratory. You will do them to answer questions from customers about the best way to grow plants.

You will investigate the effects of different variables (factors) on the growth of lettuces, peas and tomatoes. You’ll also research the answers to questions about how to achieve the best hydroponic growth conditions. The interactive allows you to examine the effect of key variables on growth: nitrogen, temperature, light intensity and light duration.

Once you are done, you might find http://splash.abc.net.au/home#!/media/1499363/the-elements-mystery-elements interesting.
