Science Fair

Term 4 Week 7

Last week room 19 conducted 3 experiments to learn how to follow the scientific method and complete a scientific investigation. The experiments also helped us with our writing topic which is writing procedures and explanations.

We are learning how to conduct a scientific investigation in preparation for our inquiry. This week we will get into groups and devise a science experiment to answer our inquiry question that is based on the sun and sun safety.

We will present these at our school science fair in week 9!

Chemical reactions- Making Hokey Pokey! 

The baking soda reacted with the hot dissolved sugar and maple syrup mixture, but why? 

We left it to cool and go hard, then we broke it up into 'crunchie' pieces! They were yummy! 

Physics and forces- Crushing cans! 

Daley heating the can with 1/4 cup of water in it over a hot flame. Others are observing. 

Look at all that steam- the pressure is building up inside the can!

Novie turning her can over into a tray of cold water- watch what happens next....

Hot air and steam hits the cold water causing the two extremes to combine....

Then 'CRACK' the can instantly crushes in on its self! 

 Fair testing- Bubble Trouble!

Making bubbles with different detergents found at home.  

Counting the bubbles and recording our results and observations.

Conducting several tests on each detergent so that the experiment is fair.

We worked in pairs, one person conducted the experiment, while the other recorded their observations. 

Writing up our experiments- Procedural writing and explanations:

Class exemplar of how to write up the science experiments (procedures and explanations)

Shared writing helps us with our own writing. Remember: always proof-read and edit!
