Insert channels in a membrane and see what happens. See how different types of channels allow particles to move through the membrane.
In this 16 minute video, Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their answers.
Also included are a concept map, slideshow, worksheet and full transcript of the video.
Transcript added from YouTube subtitles. You can use this to write your own worksheet or quiz.
Explore what happens when a force is exerted on a metallic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible for the material's mechanical properties. The molecular structure of each material affects how it responds to an applied force at the macroscopic level.
List of countries with their annual methane emissions. The data are from 2005. The data are given in total annual emissions, thus must be compared with economic activity, geographic and most importantly, population data to be relevant.
Observe changes in potential energy as molecules self-assemble into micelles.
How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.
Sample common Science Investigation Rubric for middle school performance tasks and assessments.
Overview of the activity: Introduce students to the Brainpop videos to open the discussion of what magnets are and how they can be used.
The Student Handouts for these minds-on activities challenge students to actively develop their understanding of biological concepts and apply these concepts to the interpretation of scientific evidence and real-world situations. The Teacher Notes provide learning goals, instructional suggestions, relevant scientific background, and suggestions for preparatory and follow-up activities. Many of these activities are explicitly aligned with the Next Generation Science Standards.
This a hands-on activity that can be used to show the effects of mining on the environment.
These teacher notes summarize important concepts for students to understand concerning mitosis and meiosis, including the principle that understanding meiosis and fertilization provides the basis for understanding the fundamentals of inheritance. The proposed sequence of learning activities will help students understand and learn these major concepts and progress beyond common misconceptions. This overview provides links to suggested activities which include a hands-on simulation of mitosis meiosis and fertilization, a card sort of activity, a vocabulary review game and discussion questions.
This game helps students to enjoy reviewing vocabulary related to mitosis, meiosis and fertilization. Each card in the deck has a target vocabulary word and two related taboo words that the student may not use when giving clues so the other students in his or her small group can guess the target word. Many students have trouble learning the substantial new vocabulary required for biology, and this game lets students have fun while reinforcing their understanding of key terms.
This minds-on activity is designed to help students review the processes of mitosis and meiosis and to ensure that students understand how chromosomes move during mitosis vs. meiosis. Students arrange the cards from a shuffled deck of the stages of mitosis and meiosis in the sequence of steps that occur during cell division by mitosis and another sequence of steps that occur during cell division by meiosis.
In this hands-on, minds-on activity students use model chromosomes and answer analysis and discussion questions to learn how the cell cycle produces genetically identical daughter cells. Students learn how DNA replication and mitosis ensure that each new cell gets a complete set of chromosomes with a complete set of genes. Students learn why each cell needs a complete set of genes and how genes influence phenotypic characteristics. Finally, students analyze exponential growth to understand how a single cell develops into the trillions of cells in a human body. This activity helps students meet the Next Generation Science Standards.
The student will investigate and understand simple machines and their uses. Students are learning the purpose, function and environmental examples of simple machines in their daily lives. These comprehension “mix-ups” are a great way to monitor students’ understanding of the content along with checking reading comprehension.
Science Instructional Plans (SIPs) help teachers align instruction with the Science Standards of Learning (SOL) by providing examples of how the content and the scientific and engineering practices found in the SOL and curriculum framework can be presented to students in the classroom.

Students will participate in a 5E lesson. To ENGAGE, students will connect their understanding of the characteristics of life to the fundamental molecule of life: DNA. To EXPLORE, students will extract DNA from fruit in a hands on (or video of a) lab, and then, students will act as Watson and Crick and use clues to discover the structure of DNA. In the EXPLAIN section, students will use slides to fill out guided notes on the structure of DNA and RNA. To ELABORATE on their understanding of DNA, students can participate in the CRISPR-Cas9 interactive and the Regulation of the Lactase Gene click and learn. Formative evaluations of students's ability to model DNA include (1) using an online interactive, (2) using their bodies as a class, and (3) using a cut and paste model. Finally, the summative EVALUATE is a DNA Model FlipGrid in which students use various materials to construct and explain the structure of DNA.
