Multi-level Quiz & Test Options: The Science Starters curriculum allows multi-age students between grades 3 to 6 to be taught at the same time. For your convenience we have included two different levels of quizzes and final exams so that you can choose the ones most appropriate for your student’s age and educational abilities. Resource materials included are perforated and three-hole punched – making them easy to tear out, hand out, grade, and store. Suggested levels include: Level 1 – Grades 3 & 4 Level 2 – Grades 5 & 6 Workflow: Students will read two pages in their book and then complete one page of the Student Journal. Extra Projects are also assigned. Quizzes are given at regular intervals. Lesson Scheduling: Space is given for assignment dates. There is flexibility in scheduling. While each quarter has 45 days of assignments, they do not have to be given M-F. Some students may prefer to do more assignments each day, allowing for breaks on other days. Each week listed has five days but due to vacations the school work week may not be M-F. Please adapt the days to your school schedule. As the student completes each assignment, he/she should put an “X” in the box.
Approximately 30 to 45 minutes per lesson, two to three days a week Includes answer keys for quizzes and semester test

Since 1975, Master Books has been providing educational resources based on a biblical worldview to students of all ages. At the heart of these resources is our firm belief in a literal six-day creation, a young earth, the global Flood as revealed in Genesis 1–11, and other vital evidence to help build a critical foundation of scriptural authority for everyone. By equipping students with biblical truths and their key connection to the world of science and history, it is our hope they will be able to defend their faith in a skeptical, fallen world. If the foundations are destroyed, what can the righteous do? Psalm 11:3 As the largest publisher of creation science materials in the world, Master Books is honored to partner with our authors and educators, including: Ken Ham of Answers in Genesis Dr. John Morris and Dr. Jason Lisle of the Institute for Creation Research Dr. Donald DeYoung and Michael Oard of the Creation Research Society Dr. James Stobaugh, John Hudson Tiner, Rick and Marilyn Boyer, Dr. Tom DeRosa, Todd Friel, Israel Wayne, and so many more! Whether a pre-school learner or a scholar seeking an advanced degree, we offer a wonderful selection of award-winning resources for all ages and educational levels. But sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear. 1 Peter 3:15

Science Starters: Elementary Chemistry and Physics Course Description This is the suggested course sequence that allows one core area of science to be studied per semester. You can change the sequence of the semesters per the needs or interests of your student; materials for each semester are independent of one another to allow flexibility. Semester 1: Chemistry Investigate the Possibilities: Elementary Chemistry—Matter: Its Properties & Its Changes: Infused with fun through activities and applied learning, this dynamic full-color book provides over 20 great ways to learn about bubbles, water colors, salt, and the peridodic table, all through interactive lessons that ground students in their faith in God. Help tap into the natural curiosity of young learners with activites utilizing common household items, teaching them why and how things work, what things are made of, and where they came from. Students will learn about the physical properties of chemical substances, why adding heat causes most chemical changes to react faster, the scientist who organized a chart of the known elements, and the difference between chemical changes and physical changes. Semester 2: Physics Investigate the Possibilities: Elementary Physics—Energy: Its Forms, Changes & Function: This remarkable full-color book is filled with experiments and hands-on activities, helping third to sixth graders learn how and why magnets work, different kinds of energy from wind to waves, and concepts from nuclear power to solar energy. Science comes alive as students are guided through simplified key concepts of elementary physics and through hands-on applications. Students will discover what happens to light waves when we see different colors, how you can see an invisible magnetic field, the essential parts of an electric circuit, and how solar energy can be changed into electric energy. Investigate the wonderful world God has made with science that is both exciting and educationally outstanding in this comprehensive series!

Quizzes and Test for Use with Matter Testing: This series is appropriate for elementary students from 3rd to 6th grades. Because of this, we have included quizzes and tests in two different levels, which you can choose from based on your child’s abilities and understanding of the concepts in the course. Level 1: suggested for younger ages or those who struggle with application of the concepts beyond just definitions and basic concepts Level 2: suggested for older ages or those who can both grasp the scientific concepts and apply them consistently

Solar power can be used to make a pocket calculator work; cause driveway lights to stay on all night; provide power for space vehicles; other ways. 23. Uranium atoms were splitting in half and, in the process, small amounts of mass from the uranium atoms were disappearing and changing into huge amounts of energy. This agreed with what Einstein had predicted when he proposed his equation E=mc2. 24. No. Their purpose was to figure out a logical explanation for why barium was forming as uranium was bombarded with the neutrons. Generally, scientists seek to find explanations for things that have been observed in nature, while technologists and engineers seek to apply this information and make products or find solutions to problems. 25. When the resistance stays the same, an increase in the voltage (push) also increases the current (water flow). If the resistance (close nozzle part way) increases and the voltage (push) stays the same, the current (water flow) will be smaller. If the resistance is low (nozzle opened up) and the voltage remains the same, the current (water flow) will be greater. The damaging effect of an electric shock actually comes from high current. This means the circuits with the lowest resistance would have the largest current and would be the most dangerous. Quiz One, Level 2: Chapters 1-4 1.
