This short video and interactive assessment activity is designed to teach third graders about dividing by 1 digit numbers to find work.
The tutorial that the "DjangoGirls" initiative is using for all of its workshops. It's a very beginner-friendly tutorial with introductions to the command line, Python, Django, HTML and CSS. No previous programming experience is required.
Once participants have finished the tutorial, they will have a small working web application: their own blog. The tutorial will show them how to put it online, so others will see their work.
The tutorial is available in English, French, Chinese and Ukrainian. "beta" versions of translations to other languages are also available. (The English version is considered the "original" and is usually the most maintained, complete and up-to-date one.)
Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary, and then begin to question how we know that photosynthesis occurs, if we can't see it happening. Elodea is a common water plant that students can use to directly observe evidence of photosynthesis. When Elodea is placed in a glass beaker near a good light source, bubbles of oxygen will be released as products of photosynthesis. By counting the number of bubbles that rise to the surface in a five-minute period, students can compare the photosynthetic activity of Elodea in the presence of high and low light levels.
Students explore the concept of optical character recognition (OCR) in a problem-solving environment. They research OCR and OCR techniques and then apply those methods to the design challenge by developing algorithms capable of correctly "reading" a number on a typical high school sports scoreboard. Students use the structure of the engineering design process to guide them to develop successful algorithms. In the associated activity, student groups implement, test and revise their algorithms. This software design lesson/activity set is designed to be part of a Java programming class.
This is an online lesson which introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel, and practice investigating various astronomical images using the filter wheel. This material was designed to highlight how filters are useful to astronomers and show how a real astronomical telescope uses filters to image the Sun.
Students will analyze a photograph to learn about body image. They will also discuss how society views the human body in different cultures.
Students will learn about the juxtaposition of image and text to define the social and psychological mood of the civil rights movement in the United States.
Students will engage in visual and written activities that will support their creative process of choreographing a solo dance composition. The lesson includes motifs and the movement components -- body, effort, shape, and space (BESS elements from Laban Movement Analysis).
Testing is critical to any design, whether the creation of new software or a bridge across a wide river. Despite risking the quality of the design, the testing stage is often hurried in order to get products to market. In this lesson, students focus on the testing phase of the software/systems design process. They start by exploring existing examples of program testing using the CodingBat website, which contains a series of problems and challenges that students solve using the Java programming language. Working in teams, students practice writing test cases for other groups' code, and then write test cases for a program before writing the program itself.
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.
Dogzilla is a fantasy story of mice who protect their city, Mousopolis, from being destroyed by Dogzilla. The mice come up with a plan to give Dogzilla a bath, which scares him away.
It is common in the real world to see mathematical examples where the cents sign was used when the dollar sign was supposed to be used. Converting and comparing decimals and fractions can help clear up this misconception. Two real coupons clipped from a Sunday paper coupon section are included in this activity. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
How does infrastructure meet our needs? What happens when we are cut off from that supporting infrastructure? As a class, students brainstorm, identify and explore the pathways where their food, water and energy originate, and where wastewater and solid waste go. After creating a diagram that maps a neighborhood's inputs and waste outputs, closed and open system concepts are introduced by imagining the neighborhood enclosed in a giant dome, cut off from its infrastructure systems. Students consider the implications and the importance of sustainable resource and waste management. They learn that resources are interdependent and that recycling wastes into resources is key to sustain a closed system.
After watching video clips from the Harry Potter and the Goblet of Fire movie, students explore the use of Punnett squares to predict genetic trait inheritance. The objective of this lesson is to articulate concepts related to genetics through direct immersive interaction based on the theme, The Science Behind Harry Potter. Students' interest is piqued by the use of popular culture in the classroom.
Leslie Dodson's research focuses on the intersection of micro-enterprise and digital technologies in developing communities. She brings more than 25 years of experience and insight from a career as a broadcast journalist to the academic community. Leslie has been posted to Tokyo, London, New York and throughout Latin America, where she covered high-tech and bio-tech for CNBC and MSNBC, and international finance and the global emerging markets for CNN, NHK-Tokyo and Reuters. Along with covering international business, Leslie has reported on environmental issues from the Arctic, India, Nepal, Ecuador, Burundi and Uganda. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 21-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
Students keep a doodle journal while reading short stories by a common author. In small groups, students then combine their doodles into a graphic representation of the text.
Students learn about the relocation of Japanese Americans during World War II. Through an analysis of Dorothea Lange's photographs, the "Pledge of Allegiance," and a U.S. government flyer from 1942, students discuss the complexities of U.S. history and politics.
In this activity, students use the binary number system to transmit messages. Two flashlights are used to demonstrate how astronomy spacecraft to transmit images and other scientific data to Earth. This activity is part of Unit 4 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.
Students identify the actual colors of objects bathed in monochromatic light and learn how three colors of light can be combined to produce colors ranging from black to white. Students see how space observatories make use of monochromatic filters to collect data on the color of objects in space. The activity is in unit four of the "Space-Based Astronomy" guide that contains background information, worksheets, assessment activities, extensions, and alignment to national education standards.
In this episode of Crash Course Kids, Sabrina talks about why things on the bottom of the Earth, don't just fall off into space.
