How can turmeric be used as an indicator

This hands-on activity will teach them to predict, observe, record and discuss, or present their findings. Doing experiments will provide children with an opportunity to write by recording their observations with notes or drawings. Children enjoy doing experiments, and it can be highly motivational to write, even for more reluctant writers.

Research shows that people learn best for long-term memory at least when they learn through hands-on, practical experiences. Ambrose et al. See my other vinegar and baking soda experiments so that children can explore chemical reactions:.

It can be great for children to create their own experiments based on what they want to find out. Allow them to ask questions to extend their learning. Ask them: What questions do you have about these reactions?

Can you design an experiment to answer one of the questions? They may want to see if they can find the exact amount of vinegar to make the baking soda react.

They might want to see if a frozen baking soda ball reacts faster with vinegar than a dried baking soda ball. Alternatively, they may want to see if there is a difference in the reaction between vinegar and citric acid. Ambrose, S. How learning works: Seven research-based principles for smart teaching.

Spend 7 - 10 minutes with your group working on the assigned lab problem. Turmeric, a spice and color agent in many types of cuisine, is added to yellow mustard for flavor and color.

It changes color from yellow acidic form to red basic form at a pH of 7. Mustard also contains acetic acid. Given a sample of 0.
