每週 1 小時. Students can review class content using the XplorStem Academy App. They'll complete individual lab reports and assessments. Parents can print final PDF reports with covered standards, lab reports, key concepts, vocabulary, and assessment results as class summaries. This homework is not required but is provided as a way for students to reinforce concepts and for parents to document learning progress.評估
An online assessment will be offered to the student. It will consist of 3-10 questions in a multiple-choice format. One goal is to allow students to practice taking online assessments that will prepare them for state and national science testing.我們無法翻譯此文，請刷新頁面並再試一次。

In this introductory Byte-Sized Science Career class, explore the life of a real food chemist and learn why some foods taste sour and some foods taste sweet. All our classes are NGSS-aligned and offer a science lesson and hands-on sampling of various science career paths, giving students a glimpse into their exciting possibilities. In this class, students learn about chemistry and the key concept that special molecules in our food give it a unique taste! We will talk about molecules that make food sweet and sour. Then do a hands-on experiment where students test different sweet and sour citrus foods for acid content. Hint, it is the acid that makes the food taste sour! The test is a chemical reaction between a base (baking soda) and citric acid which is the acid found in citrus fruit. Students will also learn the basics of matter, chemical reactions and the difference between chemical reactions and changes in state such as transitions from solid to liquid to gas. Students will have access to XplorStem Academy the day before and after the lesson. XplorStem academy includes additional short-format videos, vocabulary and key concepts covered, questions and answers, lab report and an assessment that reinforce what was learned in class. All concepts will be covered during the virtual session. XplorStem Academy is a way to extend learning. A PDF summary of learning may also be generated out of the academy to provide work samples and document learnings.

父母的引導和規範
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.
供應清單
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.
