It’s almost Earth Day!!!! To show appreciation, we had a guest today to show us how to be resourceful in sending messages to people. Our guest facilitator Alondra, one of our STEM Facilitators with Project Exploration, had a great activity on Invisible Ink. The concept was to write messages to each other using lemon juice. The girls were split up in pairs and to later exchange what they wrote on the paper. Alondra was very helpful in demonstrating each step to the girls and later allowing them to do it themselves.
The first step was to get the lemon juice. After Alondra and I cut lemons for the girls, they squeezed the juice out into their own cup. After that, had to set up their own candle. With Alondra’s help, the girls used the wax from the candle to stick the candle straight up on the desks. Since the candles are for the end of the experiment, it was time to get writing!! The girls had their own toothpicks as their “pens” to put the “ink” on the paper. After exchanging letters, they revealed the messages by slowly and carefully heating the paper without burning it with the lit candles.
Danaisha wrote “Hey with a smile” to Armani, Skye wrote a nice compliment to Darnasha, and Gentrice wrote her favorite saying to Ajah. It took some time to get the hang of it but I saw the girls helping each other out. They all expressed that they need to be very careful and it’s not okay to play with fire. The girls practiced fire safety techniques in order for things not to get bad and thanked Alondra for coming in and showing them a new way in writing letters. HAPPY
