Hands-On Physical Science. No-cost, easy-to-use activities teach physical science and develop scientific thinking! Developing Critical Thinking through Science presents standards-based, hands-on, minds-on activities that help students learn basic physical science principles and the scientific method of investigation. Methods Each activity is a 10- to 30-minute guided experiment in which students are prompted to verbalize their step-by-step observations, predictions, and conclusions. Reproducible pictures or charts are included when needed, but the focus is inquiry-based, hands-on science. Teaching Support: Preparation time is short, and most materials can be found around the home. Step-by-step procedures, questions, answer guidelines, and clear illustrations are provided. Practical applications at the end of each activity relate science concepts to real-life experiences. Have Your Students ever completed science experiments yet they were unable to explain: why the results came out the way they did, how science concepts relate to the real world. After completing Developing Critical Thinking through Science, your students will be able to answer the whys and hows. They will have a terrific time learning real hands-on science, and you'll enjoy it too! 144 activities. License: reproducible.
