This article, reprinted from the fall 1979 LBL News Magazine, was written about Dr. Luis Alvarez and his part in the study of geological sediments and the great extinctions.
Visit this site for an interactive tour of the atom and all aspects of particle physics. View the animations available with almost every description on this site. A great place for the fundamentals of particles and forces including a fine glossary. Shows how scientists? views of the fundamentals have changed over time. Wow!
This video narrates the curios case of the Berlin patient who was the first person considered cured of HIV.
Paula has landed on an unknown island. She learns a lot about all the different animals on this island. Join her and learn with her.
Bermuda is a mysterious place. Meet Scotty and his family and join them on their holiday to learn about energy transfer in ecosystems.
Learn about states of matter on a flight tour over the Atlantic Ocean.
Demonstrate Bernoulli's Principle using balloons and and pop cans. Real world concept of lift can be applied to an airplane demonstration.
Bernoulli's principle relates the pressure of a fluid to its elevation and its speed. Bernoulli's equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity. Students learn about the relationships between the components of the Bernoulli equation through real-life engineering examples and practice problems.
See Bernoulli\'s principle in action as you supply some fast-moving air to levitate a ping pong ball.
This activity is designed to help students understand the structures and functions of the cell by building a model.
There has been a lot of talk about free online resources but this is the first I have seen that involved anything having to do with FREE digital textbooks. Had to share!
Learn some facts about the Western pond turtle in this book. Includes audio narration in English and Spanish with text in English.
This is an impressive site about beta-thalassemia. The disease is caused when the body cannot make an important blood protein. You can find information about causes, diagnosis, treatment, lifestyle, and inheritance at this interactive multimedia site.
This site resource offers tutorials on the gas laws, balancing chemical equations, and quantum mechanics.
Students use the scientific method to determine the effect of control surfaces on a paper glider. They construct paper airplanes (model gliders) and test their performance to determine the base characteristics of the planes. Then they change one of the control surfaces and compare the results to their base glider in order to determine the cause and effect relationship of the control surfaces.
Students will make predictions and conduct an experiment using marbles to figure out what types of things can cause a moving object to change direction. Included is a video of the lesson in action, pictures, discussion questions, and a recording sheet.
Students will be able to determine a way to change the direction of a moving object by conducting a simple experiment. Included in this lesson are videos of the activity in action, a printable recording sheet, pictures of the set-up for the experiment, and discussion questions.
Use this assessment to see what your students have learned about adaptations. This type of assessment allows students to observe and make open-ended claims backed up by evidence. Included are a power point presentation, student quiz, and a video explanation.
Through the use of movement and observation, the students will be able to identify objects that can be moved and identify and problem solve how to move objects. Included in this lesson are videos of the activity, a vocabulary chart, and examples of students' work.
Students will explain commonalities in animal life cycles as well and to compare life cycles of different animal groups.
