Working with large datasets that support exploration of patterns is an essential first step in becoming fluent with data. In this dynamic data science activity, students can access part of the U.S. Census Bureau’s American Community Survey, containing demographic information about California residents (e.g., marital status, sex, place of birth, employment status, and health information). Students can try some of the suggested data science challenges, such as finding out the average income of Californians of different age groups in 2013, then engage in investigating their own questions.

Can we feed the growing population?
Only Sharing Permitted
CC BY-NC-ND
Rating
0.0 stars

Our agricultural system is made up of interconnected resources. The availability of these resources affects how much food we can produce. In this module, you will explore the resources that make up our agricultural system in order to answer the question: can we feed the growing population? Food production is faced with an ever-growing number of challenges. Growing enough food depends on the availability of resources such as arable land, sunlight, rain, and organic matter. Throughout this activity, you will explore land uses and soil quality through graphs of land use and crop production. You will run experiments with computational models to compare the effect of different management strategies on the land. You will not be able to answer the module's framing question at the end of the module, but you will be able to describe how humans can maintain and replenish important resources to be able to produce food long into the future.

There are two types of catalysis reactions: homogeneous and heterogeneous. In a homogeneous reaction, the catalyst is in the same phase as the reactants. In a heterogeneous reaction, the catalyst is in a different phase from the reactants. This activity addresses homogeneous catalysis.

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.

Ceramic Forces

Rating
0.0 stars

Explore what happens when a force is exerted on a ceramic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible for the material's mechanical properties. The molecular structure of each material affects how it responds to an applied force at the macroscopic level.

Charged and Neutral Atoms
Unrestricted Use
CC BY
Rating
0.0 stars

Explore the role of charge in interatomic interactions. The forces attracting neutral atoms are called Van der Waals attractions, which can be weak or strong, depending on the atoms involved. Charged atoms (also known as ions) can repel or attract via Coulomb forces, and the forces involved are much stronger. Oppositely charged atoms attract to each other, while similarly charged atoms repel. The attractive forces between atoms have consequences for their interactions in physical, chemical and biological applications.

Chemical Reactions and Stoichiometry
Unrestricted Use

Rating
0.0 stars

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also learn how to communicate what happens during a chemical reaction by writing the ratios of reactants and products, known as stoichiometry.

Watershed Awareness using Technology and Environmental Research for Sustainability (WATERS)

The WATERS project is developing and researching a student-centered, place-based, and accessible curriculum for teaching watershed concepts and water career awareness for students in the middle grades. This 10-lesson unit includes online, classroom, and field activities. Students use a professional-grade online GIS modeling resource, simulations, sensors, and other interactive resources to collect environmental data and analyze their local watershed issues. The WATERS project is paving a path to increased access to research-based, open access curricula that hold the potential to significantly increase awareness of and engagement with watershed concepts and career pathways in learners nationwide.

Comparing Attractive Forces
Unrestricted Use

Rating
0.0 stars

Investigate the difference in attractive force between polar and non-polar molecules by 'pulling' apart pairs of molecules. While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The force of attractions between molecules has consequences for their interactions in physical, chemical and biological applications.

Explore a NetLogo model of populations of rabbits, grass, and weeds. First, adjust the model to start with a different rabbit population size. Then adjust model variables, such as how fast the plants or weeds grow, to get more grass than weeds. Change the amount of energy the grass or weeds provide to the rabbits and the food preference. Use line graphs to monitor the effects of changes you make to the model, and determine which settings affect the proportion of grass to weeds when rabbits eat both.

Before Ernest Rutherford's famous gold foil experiment in 1911, it was not known how the positive part of the atom was distributed. His experiment showed that if you shot positively charged particles at the atoms in a very thin sheet of gold foil, that very rarely, a particle would bounce back from the foil rather than going straight through it. Experiment with changing the distribution of positive charge and see how it affects the paths of positively charged particles moving near it.

Concord Consortium: Atomic Structure
Read the Fine Print
Rating
0.0 stars

This interactive, scaffolded activity allows students to build an atom within the framework of a newer orbital model. It opens with an explanation of why the Bohr model is incorrect and provides an analogy for understanding orbitals that is simple enough for grades 8-9. As the activity progresses, students build atoms and ions by adding or removing protons, electrons, and neutrons. As changes are made, the model displays the atomic number, net charge, and isotope symbol. Try the "Add an Electron" page to build electrons around a boron nucleus and see how electrons align from lower-to-higher energy. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Concord Consortium develops deeply digital learning innovations for science, mathematics, and engineering. The models are all freely accessible. Users may register for additional free access to capture data and store student work products.

Concord Consortium: Chemical Bonds
Read the Fine Print
Rating
0.0 stars

This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

Concord Consortium: Electric Current
Read the Fine Print
Rating
0.0 stars

This 90-minute activity features six interactive molecular models to explore the relationships among voltage, current, and resistance. Students start at the atomic level to explore how voltage and resistance affect the flow of electrons. Next, they use a model to investigate how temperature can affect conductivity and resistivity. Finally, they explore how electricity can be converted to other forms of energy. The activity was developed for introductory physics courses, but the first half could be appropriate for physical science and Physics First. The formula for Ohm's Law is introduced, but calculations are not required.
