In this lesson, students are introduced to trees and the many things we commonly use that come from trees. Includes introductory movement activity, guided discussion, a matching game, and fun facts.

NGSS: Partially meets 1-LS1-1, 2-PS1-1, 2-PS1-2

Common Core: W.2.7, W.2.8

Time: 30 minutes

Materials: "Apples to Oregon" book and three paper lunch bags labled: wood, food, cellulose.

Students bury various pieces of trash in a plotted area of land outside. After two to three months, they uncover the trash to investigate what types of materials biodegrade in soil.

Students are introduced to chemical engineering and learn about its many different applications. They are provided with a basic introduction to matter and its different properties and states. An associated hands-on activity gives students a chance to test their knowledge of the states of matter and how to make observations using their five senses: touch, smell, sound, sight and taste.

Fluids flow from hot to cold at an interface such as the surface of the bubble. As the bubbles begin to freeze, the still-liquid part of the bubble keeps moving, ripping ice crystals off the growing freeze front and tossing them around. Those ice crystals each create their own freeze front, making the bubble’s surface solidify faster.

This lesson invites young students to inquire about phase changes, about what happens as water changes into ice and as ice changes into water, observing ice melting and freezing under a variety of conditions.

Students are introduced to the basic principles behind engineering and the types of engineering while learning about a popular topic - the Olympics. The involvement of engineering in modern sports is amazing and pervasive. Students learn about the techniques of engineering problem solving, including brainstorming and the engineering design process. The importance of thinking out of the box is stressed through a discussion of the engineering required to build grand, often complex, Olympic event centers. Students review what they know about kinetic and potential energy as they investigate the design of energy-absorbing materials, relating this to the design of lighter, faster and stronger sporting equipment to improve athletic performance and protect athletes. Students consider states of matter and material properties as they see the role of chemical engineering in the Olympics. Students also learn about transportation and the environment, the relationship between architecture and environment, and the relationship between architecture and engineering.

PhD Science Grade Levels K–2 is available as downloadable PDFs. The OER consists of Teacher Editions and student Science Logbooks for every module.

With PhD Science®, students explore science concepts through authentic phenomena and events—not fabricated versions—so students build concrete knowledge and solve real-world problems. Students drive the learning by asking questions, gathering evidence, developing models, and constructing explanations to demonstrate the new knowledge they’ve acquired. The coherent design of the curriculum across lessons, modules, and grade levels helps students use the concepts they’ve learned to build a deep understanding of science and set a firm foundation they’ll build on for years to come.

Cross-curricular connections are a core component within PhD Science. As an example, every module incorporates authentic texts and fine art to build knowledge and create additional accessible entry points to the topic of study.

Three-dimensional teaching and learning are at the heart of the curriculum. As students uncover Disciplinary Core Ideas by engaging in Science and Engineering Practices and applying the lens of Cross-Cutting Concepts, they move from reading about science to doing science.

Students will determine a rule for classifying outdoor objects based on physical properties of matter.

Surface tension is caused by neighboring water particles being very slightly attracted to one another — this allows water to bead and lets water strider bugs walk on water. But there are limits to the attractive forces between water molecules, and the strength of those forces can be changed by changing the temperature of the water or by mixing other substances into the water. In warmer water the molecules are moving more, so the surface tension is less. That is why warm water is used for cleaning.

Students collect, categorize, weigh and analyze classroom solid waste. The class collects waste for a week and then student groups spend a day sorting and analyzing the garbage with respect to recyclable and non-recyclable items. They discuss ways that engineers have helped to reduce the accumulation of solid waste.

What's the Matter with Trash?Have you ever wondered what happens to trash once you throw it away?  You may know that it goes to a dumpster or that the trash collectors come and get it.  But, what happens then?  Some of the items you throw away will break down into smaller parts, some might get heated in fire, and others will get buried underground in landfills and might never break down at all!  Trash and the many ways humans “get rid” of it can cause a number of health issues for the community. You will explore the properties of materials we throw away and how you can make your community cleaner and healthier by learning to recycle, reuse, and reduce waste. You will then influence your community by convincing others to improve solid waste management.
