In this lesson, students will review the basic ideas of heat, the direction it flows, and the results of this flow on the kinetic energy and expansion of the particles. Students will investigate this concept in a 5E lesson format using claim, evidence, reasoning in their conclusion. They will determine how different temperature water baths effects the ease/difficulty of opening jars with tight fitting lids and link these results to the knowledge that heat flows from warmer to cooler materials. Applying the knowledge that increasing the amount of heat of the matter will increase the kinetic energy of it's particles, will result in expansion of that matter. Because each type of matter has a different coefficient of expansion, the amount of expansion will vary in different materials. Students will realize that a jar with a tight fitting lid may loosen if hot water is applied.

Type: Lesson Plan

Students play a dice game to explore the differences between direct and indirect evidence. Student pairs roll dice and record the numbers rolled as a series of colors instead of numbers. Other pairs of students try to crack the color code to figure out the sequence of numbers rolled. In this way, students gain an understanding of how indirect evidence of climate change can be interpreted. In conclusion, the class discusses the various records made by humans and indirect evidence found in nature that can be studied to understand how climate has varied through time.

Key Concepts

• Scientists collect data from many sources to identify, understand, and interpret past changes in Earth's climate.
• Natural records of climate change, such as tree rings, ice cores, pollen and ocean sediments offer indirect evidence of climate change. They require knowledge of how the natural recorder works.
• Records made by humans , such as artwork, harvest records, and accounts of changing seasons, are more direct, but can be incomplete.

The Earth is 4.6 billion years old. That's a hard number to conceptualize. What does 4.6 billion look like, and what happened during all those hundreds of millions of years between the formation of our planet and now?

This BLOSSOMS lesson will help students conceptualize the enormity of geologic time and learn about important events in Earth's history. Students will also learn how geologic time can help explain seemingly incomprehensible processes, like the formation of the Himalayan Mountains from a flat plain to their current height, and the evolution of a tiny group of reptiles into enormous dinosaurs.
