In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side. To make the effect more dramatic, cover the mirror with a cloth, climb onto the table, straddle the mirror, and then drop the cloth as you appear to "take off." This resource contains information about how this trick was applied during the making of the movie "Star Wars."

In this simple exploration, a coiled phone cord slows the motion of a wave so you can see how a single pulse travels and what happens when two traveling wave pulses meet in the middle.

This lab activity will not only draw on students' real life experiences but will also draw on student's previous lab experiences in proper laboratory techniques and data analysis performed in previous activities. The lab will incorporate the use of scientific inquiry methods and strategies while students develop reasonable answers to the questions asked.

This task requires students to work with very large and small values expressed both in scientific notation and in decimal notation (standard form). In addition, students need to convert units of mass.

Using the context of apples, students will apply their knowledge of heredity and genetics to distinguish between sexual and asexual reproduction as they explain how new varieties of apples are developed and then propagated to meet consumer demand for a tasty, uniform, consistent product.

Apple Scientists. This is the Lesson 3 Digging Deeper activity, from Unit 7 Plant Systems, from the DIGS (Developing Individuals, Growing Stewards) AmeriCorps Curriculum from CSU. The curriculum focuses on introducing students in grades 3-5 to Colorado agriculture, industry and environmental issues. The curriculum is matched to State Standards 2021. The curriculum upon request. Visit: https://engagement.colostate.edu/programs-old/developing-individuals-growing-stewards/

In this lesson, students will explore apples using their five senses. Includes activity instructions, extension activities, songs, and apple and five senses realted reading list.

NGSS: K-ESS3-1, 1-LS1-1

Time: 30 minutes

Materials: "Apples Grow on Trees" or other book about apples.

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.

Practical lab into the chemical reaction between calcium carbide and water and the resulting ignition of acetylene gas.

In this problem set students are given Rb/Sr and 87Sr/86Sr data for whole rock and mineral samples from three granitic intrusions in the Sierra Nevada. They use these data (in EXCEL) to calculate isochron ages and initial ages for the intrusions and then interpret their results. This problem is intended to teach some spreadsheet skills (linear regressions, graphing) as well as having them think about the use of radiogenic isotopes.

Application of Oral History to Economics: Family Economic History The assignment will connect an oral history approach to the examination of economic concepts such as opportunity cost of attending school, economic crises (inflation and unemployment, etc.), and standard of living over time. Particularly, students will interview parents, grandparents, or family members from older generations regarding the types of work they performed, economic decisions they have made, and the economic conditions while they were growing up. The project develops a student's ability to understand and integrate these concepts from a variety of perspectives and real world situation.

Does the real-world application of science depend on mathematics? In this activity, students answer this question as they experience a real-world application of systems of equations. Given a system of linear equations that mathematically models a specific circuit—students start by solving a system of three equations for the currents. After becoming familiar with the parts of a breadboard, groups use a breadboard, resistors and jumper wires to each build the same (physical) electric circuit from the provided circuit diagram. Then they use voltmeters to measure the current flow across each resistor and calculate the current using Ohm’s law. They compare the mathematically derived current values to the measured values, and calculate the percentage difference of their results. This leads students to conclude that real-world applications of science do indeed depend on mathematics! Students make posters to communicate their results and conclusions. A pre/post-activity quiz and student worksheet are provided. Adjustable for math- or science-focused classrooms.

This lab exercise provides students with activities utilizing vector operations within the context of the atmospheric and oceanic environments.

Best open source book in Discrete Math. Covers all the subjects in a standard Discrete Math class for mathematics or computer science students and contains sage cells for all subjects. Set Theory, Combinatorics, Logic, Relations, Recursion, Graph Theory, Trees, Algebraic Structures, Boolean Algebras, Automata, etc. Originally published commercially, its original text was peer-reviewed and was adopted for use at several universities throughout the country. Now in its open source version, has the same quality but it is free.

Students will use state and regional unemployment data for various education levels to create scatter plots and calculate correlation coefficients. Students will then compare scatter plots with different strengths of linear relationships and will determine the impact of any influential points on the correlation coefficient.

This is a writing assignment on the topic of environmental justice for a philosophy-oriented "Philosophy and the Environment" course. It provides somewhat realist scenarios for students to demonstrate their understanding of several theories and practices emerging from environmental ethical issues including race, class, gender, indigenous peoples, and international law and economics.

Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and answering a series of application questions, students apply their new understanding to explore a tissue of known surface area. Students then use the necessary relationships to depict a cancerous tumor amidst normal tissue by creating a graph in Microsoft Excel.

In this jigsaw-method activity on subduction zone volcanism, students apply lessons learned from four historic eruptions to the volcanic hazards associated with Mt. Rainier in the Pacific Northwest.
