This is a hands-on activity to assess the students understanding of peptide and disulfide bonds formed during protein synthesis. Students demonstrate the process of dehydration synthesis by combining amino acids through peptide bonds creating molecules of water, and one protein amino acid strand. It can also be used to assess students understanding of the process of translation.

When will objects float and when will they sink? Learn how buoyancy works with blocks. Arrows show the applied forces, and you can modify the properties of the blocks and the fluid.

In this demonstration, the teacher will use a potato and hydrogen peroxide to generate oxygen in a closed environment. Students can then observe its effects on a burning wooden splint and on burning steel wool. They will understand that a large amount of energy can be released by the process of oxidation. As an extension, the teacher can discuss how the appearance of oxygen (produced by cyanobacteria) in Earth's early atmosphere initially resulted in the formation of large deposits of iron oxide (Banded Iron Formations) and then aided in the evolution of more complex life forms.

This is a short lesson plan for a second grade math class. This is a short lesson plan for a second grade math class. It aligns with the South Carolina College- and Career-Ready Standards for Mathematics Page 23: 2.MDA.7 Solve real-world/story problems involving dollar bills using the $ symbol or involving quarters, dimes, nickels, and pennies using the ¢ symbol.

This is a short lesson plan for a second grade math class. It aligns with Nebraska State Standard: MA 2.3.3.a Solve real-world problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately.

This set of animations and interactive simulations from the Byrd Polar Research Center at Ohio State University helps students develop an understanding of models used to understand the Earth system. Students consider the types of data that need to be included in a climate model, looking at inputs, outputs, and variables. The animations show how data is calculated for grid cells and assembled into a comprehensive model.

C-ROADS is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

Water is a limited resource that we use over and over again. The idea is to teach the science behind the water cycle, where water comes from and is located on the Earth. After research and developing and understanding of conservation students will create a water tower that will collect and store rainwater. Students will also create a Public Service Announcement (PSA) on water conservation.

By using the discrepant event of dropping a burning candle in a jar, students will predict, experiment, and discuss why the candle goes out as soon as it is caught.

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage and electric field.

Series of resources about the carbon cycle  with an accompanying assessment at the end.  

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

Learning Objective To familiarise students with the framework, key principles and statutes surrounding social work intervention with families and adult offenders.

This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to correct it-first, by exploring the reason for it, and then by presenting an alternate explanation. Materials needed for the demonstration include a small globe and a desk lamp for each group of students, a large ball, and overhead transparency. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Welcome to the CELLS alive BioCams. In these BioCams, you will get to learn about cancer and bacteria cells. However, these are a bit different from "livecams" you might find elsewhere on the web - these repeat at daily or shorter intervals in order to convey information on biological rhythms.

Cellular respiration is the process by which our bodies convert glucose from food into energy in the form of ATP (adenosine triphosphate). Start by exploring the ATP molecule in 3D, then use molecular models to take a step-by-step tour of the chemical reactants and products in the complex biological processes of glycolysis, the Krebs cycle, the Electron Transport Chain, and ATP synthesis. Follow atoms as they rearrange and become parts of other molecules and witness the production of high-energy ATP molecules.
