These worksheets were developed by Bryanne McDonough (PhD Candidate, Boston University) for a 6 week summer AS101 course taught at Boston University using the Openstax Astronomy 2e textbook. Each lesson was two hours long, so modification may be necessary for using these worksheets in a shorter class format, although many are already split into two parts. I'm open to feedback and would love to hear if you decide to use this resource in anyway: please contact Bryanne McDonough (bnmcd@bu.edu).

This is a concept attainment on the words: affect and effect. These words are easily confused because they are similiar. This teaching strategy has six steps for students to learn about the two words with activities that is facilitated by the teacher. At the end of the lesson, students should be able to learn the difference between affect and effect.

Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.

This is an Open Educational Resource created by University College Groningen (The Netherlands) students taking the course Biopsychology in Spring 2021.

In small teams, students were tasked with creating, composing, and curating an online portfolio dedicated to an interdisciplinary exploration of a topic of their choice. Their portfolio needed to be grounded in neuroscience, incorporate peer-reviewed research, and propose active learning exercises for future students and viewers.

Included topics:
- A trip through the world of psychedelics
- Alzheimer's disease
- Animal minds
- Biopsychological aspects of sexuality
- Consciousness
- Go with the flow: an interdisciplinary exploration of the flow state
- Happiness and well-being
- Hypnosis
- Intergenerational trauma
- Lucid dreaming
- Machine learning for mind reading
- Social and cultural neuroscience of prejudice
- Our sense of self
- Out of body experiences
- You and aesthetics

Please enjoy exploring their work!

Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

Construct and measure the energy efficiency and solar heat gain of a cardboard model house. Use a light bulb heater to imitate a real furnace and a temperature sensor to monitor and regulate the internal temperature of the house. Use a bright bulb in a gooseneck lamp to model sunlight at different times of the year, and test the effectiveness of windows for passive solar heating.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

This Project has been completed as part of a standard 10 weeks Calculus 3 asynhronous online course with optional WebEx office hours during Summer 2022 semester at MassBay Community College, Wellesley Hills, MA.

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.

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.

Users may register for additional free access to capture data and store student work products.

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.

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.

This concept-building activity contains a set of sequenced simulations for investigating how atoms can be excited to give off radiation (photons). Students explore 3-dimensional models to learn about the nature of photons as "wave packets" of light, how photons are emitted, and the connection between an atom's electron configuration and how it absorbs light. Registered users are able to use free data capture tools to take snapshots, drag thumbnails, and submit responses.

In this interactive activity, learners explore factors that cause atoms to form (or break) bonds with each other. The first simulation depicts a box containing 12 identical atoms. Using a slider to add heat, students can see the influence of temperature on formation of diatomic bonds. Simulations #2 and #3 introduce learners to reactions involving two types of atoms. Which atom forms a diatomic molecule more easily, and why? The activity concludes as students explore paired atoms (molecules). In this simulation they compare the amount of energy needed to break the molecular bonds to the energy needed to form the bonds.

In this interactive activity, learners build computer models of atoms by adding or removing electrons, protons, and neutrons. It presents the orbital model of an atom: a nucleus consisting of protons and neutrons with electrons surrounding it in regions of high probability called orbitals. Guided tasks are provided, such as constructing a lithium atom and a carbon-12 atom in the fewest possible steps. The activity concludes with a model for building a charged hydrogen atom (an ion). Within each task, students take snapshots of their work product and answer probative questions.

This activity describes the construction and use of a pneumatic cannon and free falling target used to teach the concepts of projectile motion in introductory physics.
