Create a memorable scientific experience for Halloween, end-of-school-year celebrations, summer camp programs, or any time of year. Students will follow the scientific method, record observations, and make inferences while exploring one of the BEST kid-friendly chemical reactions! A clear teacher guide, student pages, and video demonstrations are included.

Students will explore exothermic reactions by following the scientific method. They will discover if increasing the concentration of hydrogen peroxide affects the temperature of elephant toothpaste. The final activity allows students to create their own elephant toothpaste investigation. This can be completed as a whole class, in groups, or as a science fair project. The journal will take students step-by-step through the process. Perfect for meeting the Science and Engineering Practices of NGSS and CER.
Assessment is included.

The journal meets the Next Generation Science Standards

• 3rd-5th Grade Science and Engineering Practices
