This lesson's primary focus is to introduce high school students to the concept of Elasticity, which is one of the fundamental concepts in the understanding of the physics of deformation in solids. The main learning objectives are: (1) To understand the essential concept of Elasticity and be able to distinguish simple solids objects based on degree and extent of their elastic properties; (2) To appreciate the utility of the elastic force vs. deformation curve through experiments; (3) To be aware of potential sources of error present in such experiments and identify corrective measures; and (4) To appreciate the relevance of Elasticity in practical applications.

This BLOSSOMS lesson discusses Carbon Dioxide, and its impact on climate change. The main learning objective is for students to become more familiar with human production of Carbon Dioxide gas, as well as to gain an awareness of the potential for this gas to effect the temperature of Earth’s atmosphere. This lesson should take about an hour to complete. In order to complete the lesson, the teacher will need: printed copies of signs representing the different products and processes that take place in the carbon cycle (included), samples of matter that represent those products, handouts for the students to create a graphic of the carbon cycle (included) and graph paper or graphing software for students to create graphs. In the breaks of this BLOSSOMS lesson, students will be creating models of the carbon cycle as well as observing experiments and analyzing data from them. It is hoped that this lesson will familiarize students with ways in which carbon moves through our environment and provide them with some personal connection to the impact that an increased concentration of CO₂ can have on air temperature. The goal is to spark their interest and hopefully to encourage them to ask and investigate more questions about the climate.

At the end of this lesson, students will be able to identify the forces acting on a sailboat and explain how the combination of these forces results in the forward motion of a sailboat. Students should be familiar with vectors and be able to use them to represent forces and moments, and also should be familiar with using free body diagrams to represent forces and moments. The classroom activity challenges are centered around small-group discussions based on the questions posed before each break. Free body diagrams, or another conceptual representation of his or her answer, should support each student’s solution to the questions posed in the video.

This tutorial will help you to understand how bone growth is different from the growth of many other organs. Although bone may appear to be rigid and lifeless it is actually living tissue that is capable of growth. Unlike soft tissues, bone cannot simply grow by adding additional cells and removing cells that are no longer necessary. The calcium laid down in bone gives the skeleton the strength and rigidity needed to protect and support the body. This rigidity means that expansion requires addition of cells on the outside and, when necessary, the removal of calcium and other materials on the inside.

Blood pressure is determined by the force of the blood acting on the walls of the blood vessels. Two factors determine the size of this force. One is the volume of blood being pumped through the vessel. The other is the size of the vessels.

You can explore concepts in many ways including:

• Describe the relationships between volume and amount of solute to solution concentration.
• Explain qualitatively the relationship between solution color and concentration.
• Predict and explain how solution concentration will change for adding or removing: water, solute, and/or solution.
• Calculate the concentration of solutions in units of molarity (mol/L).
• Design a procedure for creating a solution of a given concentration.
• Identify when a solution is saturated and predict how concentration will change for adding or removing: water, solute, and/or solution.
• Describe the relationship between the solution concentration and the intensity of light that is absorbed/transmitted.
• Describe the relationship between absorbance, molar absorptivity, path length, and concentration in Beer's Law.
• Predict how the intensity of light absorbed/transmitted will change with changes in solution type, solution concentration, container width, or light source and explain why?

Understanding molecular polarity by changing the electron-negativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D.

Some learning goals:
•predict bond polarity using electron-negativity values
•indicate polarity with a polar arrow or partial charges
•rank bonds in order of polarity
•predict molecular polarity using bond polarity and molecular shape

An electronic kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

Other options for exploration:

• Discuss basic electricity relationships
• Build circuits from schematic drawings.
• Use an ammeter and voltmeter to take readings in circuits.
• Provide reasoning to explain the measurements and relationship in circuits.
• Discuss basic electricity relationships in series and parallel circuits.
• Provide reasoning to explain the measurements in circuits.
• Determine the resistance of common objects in the "Grab Bag".

This simulation allows you to explore forces and motion as you push household objects up and down a ramp. Observe how the angle of inclination affects the parallel forces. Graphical representation of forces, energy and work makes it easier to understand the concept.

Some of the learning goals can be:

• Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
• Explain the effects with the help of a free body diagram
• Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
• Explain how the graphs relate to one another.
• Given a scenario or a graph, sketch all four graphs.

Type: Virtual Manipulative

The students will drag a red point across the screen in any direction they please and, in the process, will be able to see the forces that are being put on that point at any given moment.

Type: Virtual Manipulative

The students will try to move a red ball into a blue goal without touching the walls. They will have fun competing amongst themselves to get the best time but at the same time they will also be learning about vectors, velocity, and acceleration.

Type: Virtual Manipulative

This simulation demonstrates the physics of projectile motion. The user can fire different objects through a cannon, set its speed, angle and mass and observe the resultant motion.

Type: Virtual Manipulative

The students will rub a balloon on a sweater and see how charges are exchanged between the two objects. With these changes they will see their interactions.

Type: Virtual Manipulative

The students will have the opportunity to build their own circuit loop with the materials presented to them.

In this interactive Biotechniques virtual lab, you will isolate DNA from a human test subject and learn the uses for DNA obtained through extraction. The "Try It Yourself" section below the virtual lab gives instruction and background information about how to extract DNA from living tissue using basic materials available in grocery stores.
