Thinking like a Scientist

Room 8 brainstormed how to think like a scientist!

We need to:

Predict what might happen - What do you already know? What do you think could happen?
Observe closely - use your senses - look, listen, smell, and touch (ask the teacher first)
Explain what has happened (share ideas) - What did you observe?  Why do you think that happened?
Ask Questions and talk with other scientists (peers) - What questions do you still have?  What do we need to find more information about?  What are your ‘what if?’ questions?  What are you still wondering about?    
Reflect and think - Why did it happen?  What did you find out/discover?  What do you want to learn more about now?
Record our findings and share them - DLO, draw, write, label, caption, photograph, video.

So far we have investigated how red cabbage is an Acid and Base Indicator and looked for chemical reactions (change in temperate, creating a gas, changing colour) when mixing calcium chloride (damp rid), baking soda and water. Here are a few photos from our Room 8 laboratory. 

We found out that when we mix the baking soda and damp rid together they created bubbles and gas (CO2). The plastic bag filled up quick and popped because of all the gas inside.

When we use Red Cabbage Water, the chemical in it called anthocyanin (an-tho-sigh-a-nin) turns red in acidic environments and bluish-green in basic environments.

What colour do you think lemon juice would turn, red or blue? What about hand sanitizer?
