Type: Lesson Plan

The purpose of this lesson is to introduce students to the concept of sea level rise as it occurs through climate change by having them examine 3 specific parameters:  ice distribution, thermal expansion, and analyzing and interpreting data.  The lesson and activities within the lesson were designed using the three dimensions of the Framework for K-12 Science Education and the Next Generation Science Standards – specifically crosscutting concepts, science and engineering practices, and disciplinary core ideas. While there isn’t any required pre-requisite learning required for this lesson, a general understanding of sea-level rise, glaciers, and climate may be beneficial to students. During classroom breaks, pairs of students will develop/discuss their models, revise their interpretations of their models or data, and think-pair-share their thoughts on the investigation segments.

Type: Lesson Plan

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.

The tutorial also covers more complex patterns of inheritance such those resulting from multiple alleles. Note: This resource is part of a larger collection of information regarding Genetics. Users may view information before and after the specific genetics components highlighted here.

Learn more about collisions with the use of a virtual air hockey table. Investigate simple and complex collisions in one and two dimensions.Experiment with the number of discs, masses and initial conditions. Vary the elasticity and see how the total momentum and kinetic energy changes during collisions.

Some of the sample learning goals can be:

• Draw "Before and After" pictures of collisions.
• Construct momentum vector representations of "Before and After" collisions.
• Apply law of conservation of momentum to solve problems with collisions.
• Explain why energy is not conserved and varies in some collisions.
• Determine the change in mechanical energy in collisions of varying "elasticity".
• What does "elasticity" mean?

The split brain experiments revealed that the right and the left hemisphere in the brain are good at different things. For instance, the right hemisphere is good at space perception tasks and music while the left is good at verbal and analytic tasks. This game guides students through some examples of the split-brain phenomenon and how the differences are understood.

This virtual manipulative will help the students to understand that osmosis is the movement of water molecules from an area of high concentration across a semipermeable membrane to an area of low concentration. This illustration of the diffusion process will help the students to understand the concept of osmotic pressure which is created by the movement of the water based on their concentration gradient and thus resulting in the difference of the solute concentration.

This virtual manipulative will help you investigate how Rutherford figured out the structure of the atom without being able to see it. This simulation will allow the you to explore the famous experiment in which Rutherford disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.
Further explorations of the tutorial could include:

• Describe the qualitative difference between scattering off positively charged nuclei and electrically neutral plum pudding atoms.
• For a charged nucleus, describe qualitatively how angle of deflection depends on: energy of incoming particle, impact parameters, and charge of target.

This activity will allow you to practice balancing a chemical equation. You will have to make sure you are following the law of conservation of mass and recognize what can change to balance an equation.
You can:

• Balance a chemical equation.
• Recognize that the number of atoms of each element is conserved in a chemical reaction.
• Describe the difference between coefficients and subscripts in a chemical equation.
• Translate from symbolic to molecular representation.

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

Students will pump gas molecules to a box and see what happens as they change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

• Students can predict how changing a variable among pressure, volume, temperature and number influences other gas properties.
• Students can predict how changing temperature will affect the speed of molecules.
• Students can rank the speed of molecules in thermal equilibrium based on the relative masses of molecules.

With this simulation you can:

• Investigate how pressure changes in air and water.
• Discover how to change pressure.
• Predict pressure in a variety of situations.

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.

This interactive cell membrane simulation allows students to see how different types of channels allow particles to move through the membrane.

Sample learning goals:

• Predict when particles will move through the membrane and when they will not.
• Identify which particle type will diffuse depending on which type of channels are present.
• Predict the rate of diffusion based on the number and type of channels present.
