A one-page handout for the lesson will be provided upon enrollment. Students will be testing the amount of citric acid in different citrus fruits by adding baking soda to the juice.  We suggest lemons, limes and oranges.  XplorStem Academy provides details for cutting the fruit and making the juice.  

Parents may want to help students prepare the juice in advance of class depending on the child's level of proficiency in using a knife and also strength to make the juice. Having fruit pre-juiced will not diminish the learning experience!  They will also need baking soda and soap.  We suggest clear plastic cups that hold up to 5 cups of solution (to minimize mess), measuring cups and spoons, a sharpie to label the cups and a paper plate again to minimize mess. Students will also need water as a control.  Normal tap water is fine for this experiment. 

除了 Outschool 教室外，本課程也使用：
XplorStem Academy

This course provides complimentary access to XplorStem Academy, a STEM education platform funded by the National Science Foundation. Through interactive Q&A sessions and concise educational videos, students delve into scientific concepts. Additionally, the platform offers detailed instructions for hands-on lab activities conducted in class. Following each session, students engage in wrap-up questions and an online evaluation. 

Password and Login information is supplied upon enrollment.

Parents have the option to generate a comprehensive PDF summarizing the covered topics, alignment with NGSS standards, lab reports, and assessment outcomes for future reference and documentation. 

While utilization of the platform isn't mandatory, our research indicates enhanced learning outcomes for students who engage with it. Rest assured, the platform maintains anonymity and does not gather any personal information about the student and is consistent with Outschool policies.

For some lessons, we may provide links to peer-reviewed articles outlining the history of the career and science topic covered in class.  This will be provided in the parent PDF and it is up to the parent to review with the child.

ADVISE: Please have the supplies ready for this class. Please provide your learner a clear space to work, any necessary eye, clothing or hand protections. Parents are encouraged to supervise from a distance and provide assistance as needed.
