Our  Primary 1 Scientists have been busy at work

• Let’s Investigate – Squeaky Clean
• We are learning what is the best liquid for cleaning.
• Success Criteria
• I can talk about liquids that clean (detergents)
• I can give my own experiences of a cleaning liquid such as: washing up liquid, shampoo or bubble bath.
• I can help to plan for the investigation, changing only one variable.
• I can make my guess.
• I can observe and record the changes.
• I can talk about the result and make my conclusions.
• We needed 3 bottles, water and 3 detergents
• We put the same amount of water into 3 bottles of the same size.
• We put the same amount of liquid into the three bottles but we changed the type of liquid.
• We used – washing up liquid, Shampoo and Bubble Bath
• We made our prediction.
• We shook the bottles to make bubbles.
• We observed and measured the height of the bubbles.
• We recorded the results and made our conclusions.

We noted that the washing up liquid produced the most bubbles and was the strongest detergent.
