This is a short video outlining the causes and effects of a magnitude 9.2 earthquake in Alaska in 1964. Additional resources include a background essay and discussion questions.
This animation illustrates how seismic waves travel through the earth to a single seismic station. Scale and movement of the seismic station are greatly exaggerated to depict the relative motion recorded by the seismogram as P, S, and surface waves arrive.
In this unit, students will learn about ticker tape diagrams and vector diagrams. Lessons in this unit include: Introduction; Ticker Tape Diagrams; and Vector Diagrams. This unit includes animations and mini quizzes to check for understanding and facilitate learning.

This unit includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
In this unit students will learn how to analyze the motion of objects. Students will begin to make a mathematical connection with words that describe motion. This unit will focus on several examples of vector and scalar quantities (distance, displacement, speed, velocity, and acceleration). As students proceed through the lessons, they should give careful attention to the vector and scalar nature of each quantity. This tutorial also includes animations of each of the major concepts. At the end of each lesson students can check for understanding of concepts by answering concept questions.
In this unit, students will learn about free fall and the acceleration of gravity. Lessons in this unit include: Introduction to Free Fall; The Acceleration of Gravity; Representing Free Fall by Graphs; How Fast? and How Far? This unit includes videos, animations, and mini quizzes to check for understanding and facilitate learning.
Students will learn about the the hazards chemicals pose to the people who use them while learning about states of matter and kinetic molecular theory. First, students examine physical properties and hazards of substances and mixtures. Next, students examine how different gases respond to temperature changes and how different concentrations of salt water respond to temperature changes. Students engage in collaboration, analysis of data through board discussions, and writing an analysis using claim-evidence-reasoning. Using a phet simulation, students then model what happens to particles during increase and decrease in energy. Students then investigate thermal transfer through a water mixing lab. Finally, students engage in an ice cream engineering activity to examine how different substances in similar conditions can have different properties which may be harmful or beneficial.
In Part 1 of this unit, students will learn about data collection, graphing skills (both by hand and computer aided [Desmos]), and the fundamental mathematical patterns of the course: horizontal line, proportional, linear, quadratic, and inverse. Students perform several experiments, each targeting a different pattern and build the mathematical models of physical phenomena. During each experiment, students start with an uninformed wild guess, then through inquiry and making sense through group consensus, can make an accurate data informed prediction.
This activity is intended to introduce students to the distinction between vector and scalar quantities and to give them practice manipulating vectors (converting between X/Y and magnitude/angle representations) in a context that is concrete and easy to understand.

In this lesson, students collect 3 samples of soil from different outdoor locations, recording observations and questions about each location in their science notebooks. On the second day of the investigation, students will work in collaborative groups to investigate the soil using hand lenses, sifters/strainers, and sorting pans. Then students will share what they have learned with their peers.
Students will learn about elements, atoms, and the Periodic table through the phenomena - How do you know if your water is safe to drink? What kind of substances in water might be hazardous? First, student will learn atoms are made up of subatomic particles, which give rise to predictable properties through a phet simulation. Next, students will try to build their own table looking for patterns in element cards. Students will then look at properties of elements which are divided into metals and nonmetals. Student will then look at electron configuration through a POGIl activity. Students will also complete a flame test activity. Finally, students when end the unit with a engineering project examining water quality to determine if it is safe to drink.
This animation shows the effect of change the volume of a gas phase equilibrium mixture where the numbers of reactant and product molecules are different.

Students can work individually or in groups of 3 or 4 to create a solar oven out of a pizza box. Students are trying to figure out the best way to make a solar oven in order to melt the chocolate and marshmallow in the S’more. Students will be given a group of objects and tell them the basis of how to create a solar oven. The oven will need to be placed in direct sunlight for most of the day. This experiment works best on a very hot, sunny day.
Students are confronted with a scenario of a student who is texting and driving in the school parking lot and they are tasked to determine the effect of various parameters to see if a student will collide with a pedestrian. Students must begin by breaking the scenario down into more manageable parts to determine what must be studied about the situation. Through a series of labs and activities, students learn how to model and predict situations with constant velocity and acceleration. Then, coding a spreadsheet, students model the complex situation of a texting driver, reacting, and braking during a potentially hazardous situation to create an evidence-based argument.
