Este video describe algunas de las formas en que se puede aplicar la electroforesis en gel en el mundo real, desde la medicina forense hasta la clonación de genes.
Read the minute-by-minute flight plan of Apollo 11. Links to other information about Apollo 11.
This site contains facts and images pertaining to the crew, spacecraft, and mission of Apollo 13.
A comprehensive site focused on all of the Apollo missions. Includes details on launches and moon landings, with charts, statistics, and images. Especially interesting is the list of "Top Ten Apollo Results," which explains the major discoveries from the Apollo missions.
This resource offers an in-depth exploration of the U.S. space program and the role President John F. Kennedy took in setting the agenda for manned space flight to the moon.
Learn how apoptosis is different from cell death by injury. Learn the role of this process in development and body maintenance. [10:48]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Grades 9-12. Describes the logic behind the development of Newton's law of universal gravitation. Beginning with Johannes Kepler and his three laws of planetary motion, content walks the reader through Newton's thought process and development of this theory. Detailed diagrams and animation of planetary motion are also provided.
Practical lab into the chemical reaction between calcium carbide and water and the resulting ignition of acetylene gas.
To create HIV-resistant immune cells with the gene editing tool CRISPR-Cas9, a specific macrophage gene must be disrupted.
This final lesson in the unit culminates with the Go Public phase of the legacy cycle. In the associated activities, students use linear models to depict Hooke's law as well as Ohm's law. To conclude the lesson, students apply they have learned throughout the unit to answer the grand challenge question in a writing assignment.
This interactive will present the varying applications of the laboratory technique Polymerase Chain Reaction, also known as PCR.
Does the real-world application of science depend on mathematics? In this activity, students answer this question as they experience a real-world application of systems of equations. Given a system of linear equations that mathematically models a specific circuit—students start by solving a system of three equations for the currents. After becoming familiar with the parts of a breadboard, groups use a breadboard, resistors and jumper wires to each build the same (physical) electric circuit from the provided circuit diagram. Then they use voltmeters to measure the current flow across each resistor and calculate the current using Ohm’s law. They compare the mathematically derived current values to the measured values, and calculate the percentage difference of their results. This leads students to conclude that real-world applications of science do indeed depend on mathematics! Students make posters to communicate their results and conclusions. A pre/post-activity quiz and student worksheet are provided. Adjustable for math- or science-focused classrooms.
Questo video descrive alcuni dei modi in cui l'elettroforesi su gel può essere applicata nel mondo reale, dalla medicina legale alla clonazione genica.
Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and answering a series of application questions, students apply their new understanding to explore a tissue of known surface area. Students then use the necessary relationships to depict a cancerous tumor amidst normal tissue by creating a graph in Microsoft Excel.
In this jigsaw-method activity on subduction zone volcanism, students apply lessons learned from four historic eruptions to the volcanic hazards associated with Mt. Rainier in the Pacific Northwest.
In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust.
This is one page from a site on Welks. It tells about how many of the eggs will survive, the growth rate, how old a whelk can live to be, and it talks about poorly distrubited genes.
Through a video lecture, students discover the visual side of the important applications of mathematics in practical life. More specifically, they will understand the relationship of mathematics and decoration or art.
This video segment adapted from "Building Big" illustrates the strength of the arch in bridge design and construction. [1:47]
