This activity is a lab where students will be working with chemical changes and reactions. It's a simple activity that can be done with household items.

In 1950, Percy Julian was one of the few African Americans with a Ph.D. He was Chicago's man of the year and a groundbreaking scientist. But it wasn't an easy road. Denied teaching positions and the target of death threats, Julian struggled to get ahead in a racially hostile world. Learn more about Percy Julian's contributions to science and civil rights. These resources, adapted from NOVA: Forgotten Genius, explore how Julian revolutionized chemistry with the first synthesis of a chemical compound, as well as the challenges he overcame as an African American facing legalized segregation.

This resource is an interactive website assignment, which will allow students to explore the organization and elements of the periodic table. The resource includes a link to an outside source (interactive periodic table). The atomic number, atomic mass, period #, group #, classification, melting point, atomic radius, electronegativity, state of matter, boiling point, outer orbital, and abundance of each element can be found in the outside source. This resource will allow students to see for themselves how the periodic table is organized and the different properties of the elements, along with requiring them to answer various questions relating to the topics above.

This is an introduction to the History on the development and contributions of the modern periodic table.The lesson includes a PowerPoint, activities, Pretest and a lab.

This template is meant to be a guide for Nebraska Teachers when creating Units of Instruction for the BlendEd Best Practices Project. Headings and/or topics not included in the lesson plan should be marked N/A.

This Demonstration shows 3D bar charts of the periodic table with various element property values.

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev.

This module introduces D. Mendeleev's theories and the modern Periodic Table. Electron configuration as a function of table placement is discussed.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

This activity teaches students about the periodic table and how element properties can be predicted through periodic trends.

Explore naturally occurring frozen methane deposits under the sea with renowned geochemist Miriam Kastner and discover whether or not they are a hazard to climate change. (53 minutes)

Investigations into the oceanŐs role in the global carbon cycle have taken on increasing importance as scientists strive to understand the potential impacts of global change. Join Scripps ocean chemist Lihini Aluwihare as she explains how her research is helping to understand the biology, Geology|Earth Science, and chemistry of the oceans, and ultimately the Planet. (57 minutes)

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

This lesson is focused on the short-term cycling of carbon and is designed to put the processes of photosynthesis and respiration within a global perspective.

SYNOPSIS: In this lesson, students engage in activities and experiments to explore the concept of physical changes, and apply their learning to understand climate change-induced sea level rise.

SCIENTIST NOTES: The lesson introduces students to the physical changes of state from solid-liquid-gaseous phase. All materials, including artcicles and simulations, are well-sourced and relevant to improve students' ability in understanding the impact of physical changes in ice caps and its ambient environment and how they could take action to limit these changes. This lesson has passed our science credibility process and is recommended for teaching.

Positive

-Students work collaboratively in groups and with partners to share diverse ideas and perspectives.
-Students participate in hands-on learning to aid in understanding and participation.
-Students learn through a variety of pathways including kinesthetic, auditory, visual, etc. to engage with different learning.
-Students are given a variety of optional extensions to create the most meaningful change in their communities.

ADDITIONAL PREREQUISITES:
-It is recommended that teachers use this as a multi-day lesson in 5 parts. Use the Multi-Day Schedule Visual to determine appropriate stopping points for each day.
-Materials needed for the Physical Change Activity include the following:
-Ice
-Cup
-Playdough (one container per group)
-Different shaped cookie cutters (two per group)
-Materials needed for each group for the Investigate section experiment include the following:
-Two identical, clear, plastic containers (e.g., 6x6 inches)
-Clay, playdough, or small rocks
-Tray of ice cubes
-Ruler
-Cold water
-Piece of paper
-Permanent marker (optional)
-Materials may be substituted as necessary
-Students must create free accounts on the CK-12 website to participate in the simulations.

DIFFERENTIATION:
-All activities, experiments, and simulations can be completed in differentiated groups or as demonstrations at the discretion of the teacher.
-The article may be read aloud in groups or as a class to aid in understanding at the discretion of the teacher.
-Student Document questions may be completed individually, in mixed ability groups, or as a whole group led by the teacher.
-Videos may be paused and discussed in short segments.
-As noted in the TED video, the economic influences on climate change cannot be ignored. An extension to this lesson may be to include a social studies educator to teach students about the local economic elements and issues that contribute to climate change.

This module includes a mini-lecture (5 minutes) that defines specific heat capacity and includes an examples (no unit conversions).

This activity is a method of tying a multitude of physical (and chemical) properties together showing what makes a substance unique and identifiable. This activity is a great way to lead the students into developing their procedures, their further investigations, and yet giving them the feeling of responsibility and ownership for their learning.

This is a fun way to engage students on paradoxes or misconceptions about physical properties.  This module specifically targets common misconceptions about temperature, heat, and thermal conductivity.

Students will complete a laboratory experiment, followed by answering questions as to whether the changes were physical or chemical in nature.
