This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum cleaner. The site provides an explanation of what happens, asks questions about the activity, and also describes applications to flight. This activity is part of Exploratorium's Science Snacks series.

This activity is a lab investigation where students design a balloon car to collect data about speed and velocity.

In this structured inquiry activity students will work in groups/ teams to build a balloon rocket of their own design. The rocket will race in one dimension and require that they apply their knowledge of position, time, and velocity.

The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.

The purpose of this task is to provide students with a multi-step problem involving volume and to give them a chance to discuss the difference between exact calculations and their meaning in a context.

The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.

In the open ocean around the Bahamas, pods of wild Spotted Dolphins frolic in the sunshine. Sometimes, they get bored and approach boats. In this educational video, Jonathan joins dolphin expert Wayne Scott Smith to learn how dolphins interact with each other. Jonathan learns how to play the Bandana Game, a game of -keep away- that the dolphins invented and like to play with Scott. Please see the accompanying study guide for educational objectives and discussion points.

This real world task requires students to answer questions about equations for calculating compound interest.

This task asks students to use similarity to solve a problem in a context that will be familiar to many, though most students are accustomed to using intuition rather than geometric reasoning to set up the shot.

The purpose of this task is to help students understand what is meant by a base and its corresponding height in a triangle and to be able to correctly identify all three base-height pairs.

This task could be put to good use in an instructional sequence designed to develop knowledge related to students' understanding of linear functions in contexts. Though students could work independently on the task, collaboration with peers is more likely to result in the exploration of a range of interpretations.

This unit introduces basic computing concepts and terminology. It identifies common elements of computers, both in terms of hardware and software and provides information on selecting a computer by discussing the range of computer types, from desktops to laptops to servers. Finally, it provides a history of the development of computing and healthcare information systems over time.

This task involves a fairly straightforward decaying exponential. Filling out the table and developing the general formula is complicated only by the need to work with a fraction that requires decisions about rounding and precision.

This task describes two linear functions using two different representations. To draw conclusions about the quantities, students have to find a common way of describing them. We have presented three solutions (1) Finding equations for both functions. (2) Using tables of values. (3) Using graphs.

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).

In this activity, students learn about their heart rate and different ways it can be measured. Students construct a simple measurement device using clay and a toothpick, and then use this device to measure their heart rate under different circumstances (i.e., sitting, standing and jumping). Students make predictions and record data on a worksheet.

Every day, teachers make thousands of decisions: what content to teach, what activities to assign, who to call on, how to respond to a student question, how to react to student behavior. These day-to-day decisions can have an enormous effect on the lives of young people, for good and ill. They can open new doors or cause lasting harm; they can make students feel seen and valued, or dampen their interest in school. In this course, we will investigate these interactions, rehearse responding to difficult scenarios, and develop a set of equity teaching mindsets and practices to support all of our learners, especially underserved students.
With colleagues from your school or organization and online learners around the world, you will participate in four cycles of inquiry, practice, and action, and then complete a final action project. In each cycle of inquiry, you will examine and re-examine dimensions of inequality through educator mindsets, imagine community change through documentary case studies, rehearse taking action in thorny situations through digital practice spaces, and begin to lead change through action-oriented assignments. Our early investigations will focus on relationships and interactions with individual students, and pan out to examine the effects of bias on classrooms, schools, and communities. As you complete activities with peers online, you will develop a rich set of resources and exercises to use with your students and colleagues in your local context.
At the end of the course, you will have a better understanding of yourself and your students, new resources to draw on for helping all students thrive, and a plan to work with your school community to advance the lifelong work of equitable teaching.
This course is part of the Open Learning Library, which is free to use. You have the option to sign up and enroll in the course if you want to track your progress, or you can view and use all the materials without enrolling.

Becoming the Next Bill Nye is about using video production techniques to develop your ability to engagingly convey your passions for science, technology, engineering, and / or math. You’ll have the opportunity to script and on-screen host 5-minute YouTube science, technology, engineering, and / or math-related shows to inspire youth to consider a future in science.
