This activity is designed to compare and contrast the anatomy of the leg bones of a bird vs. a human.
In this field investigation, students compare various soil samples taken from specific locations. Students compare samples, record data, create a chart or graph, and journal.
The lesson is designed for fourth grade students using scientific investigation to identify and compare the basic parts of a plant and animal cells. This activity consists of several steps over a period of several days. It includes student use of microscopes for observations and journals to collect data to identify and classify the basic parts of plant and animal cells. The assessment has an individual component and uses student work.
This scrollable explains why there are so many inactive ingredients in drug tablets. Not only does the medicine need to be released in a way that is effective, but customer preferences, shelf life and storage considerations must also be taken into account. Exploring the mechanisms of how tablets interact with the body helps explain the important roles of each type of ingredient.
Explore how populations change over time in a NetLogo model of sheep and grass. Experiment with the initial number of sheep, the sheep birthrate, the amount of energy sheep gain from the grass, and the rate at which the grass re-grows. Remove sheep that have a particular trait (better teeth) from the population, then watch what happens to the sheep teeth trait in the population as a whole. Consider conflicting selection pressures to make predictions about other instances of natural selection.
In this activity, you will read the book "Diary of a Worm" and then your students will create their own diary.
Esta vía describe cómo la ADN ligasa, una enzima clave en la replicación del ADN, se usa en la clonación de genes para crear un plásmido recombinante. Esta vía es compatible con el laboratorio 3 de ABE: Creación de un plásmido recombinante.
Esta vía explica cómo se utilizan las enzimas de restricción en la clonación de genes para obtener las piezas de ADN que crearán un plásmido recombinante. Esta vía es compatible con los laboratorios ABE 2, 2a, 3, 4 y 4a.
This lesson will focus on the dynamics and interactions surrounding coral! While exploring in Aurelia, you will have seen the different organisms that call coral reefs their home. This lesson will expand on coral, how they create such a uniquely diverse and productive environment, how organisms within this habitat support each other through symbiosis and how these natural interactions can be used to protect our coral reef
ecosystems.
Estimated time required: 1-2 class periods.
Technology required for this lesson: Tablet or Smartphone.
Grades 6-8. In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of the plants' stem, leaves and roots. They use these observations to guide their solution to the engineering design problem. The biological processes of photosynthesis and transpiration are briefly explained to help students make informed decisions about planning and interpreting their investigation and its results.
What do bats have to do with coronaviruses? As it turns out, the adaptation to flight may be what turned bats into perfect virus reservoirs. One of these viruses, the new coronavirus, likely jumped the species barrier to humans causing the initial 2019 outbreak in China. This pathway explores the outbreak from the perspective of medical professionals working to accurately diagnose and treat patients, scientists racing to understand the source of the outbreak, and public health officials implementing solutions to control its spread.
In questo video didattico, gli insegnanti delle scuole superiori Anu Deshpande e Aaron Matthieu spiegano cos’è un plasmide e perché è uno strumento utile nella biotecnologia.
This activity is a field investigation where students observe plants, animals, and insects that are common to Minnesota.
This activity is a field investigation of the biodiversity in a given area. The exercise will give students experience making scientific observations and creating a dichotomous key.
Esta animación describe el modo en que las bacterias se cultivan en el laboratorio y las distintas fases del crecimiento bacteriano, incluidas la fase de latencia, exponencial, estacionaria y de mortalidad.
This activity is a field investigation where student gather data on organisms they find in or around a pond.
Esta animação descreve como é efetuada a cultura de bactérias no laboratório e as diferentes fases de crescimento bacteriano, incluindo as fases de adaptação, exponencial, estacionária e de decaimento.
Questa animazione descrive come i batteri vengono coltivati in laboratorio e le diverse fasi della crescita batterica, che comprendono latenza, crescita esponenziale, stazionarietà e morte.
This activity will help students learn about Minnesota animals and characteristics that distinguish them from one another.
Questo video spiega come ordinare le molecole piccole utilizzando una tecnica chiamata cromatografia su colonna.
