Identifying Pond Microorganisms

In this activity you will use MULTIPLE websites to try to identify some of the microorganisms you are observing in your sample of pond water. En esta actividad, utilizará MÚLTIPLES sitios web para tratar de identificar algunos de los microorganismos que está observando en su muestra de agua de estanque.
This is just a picture... you can get ideas from it, but you need to use the websites below to try to identify what you see in your pond water. Esta es solo una imagen ... puede obtener ideas de ella, pero debe usar los siguientes sitios web para tratar de identificar lo que ve en el agua de su estanque.

Use the following websites to help you identify as many of the organisms you can see in our pond water sample as possible. Draw detailed diagrams of the organisms you see and draw a comparison diagram from one of the websites. Use los siguientes sitios web para ayudarlo a identificar la mayor cantidad posible de organismos que pueda ver en nuestra muestra de agua de estanque. Dibuje diagramas detallados de los organismos que ve y dibuje un diagrama de comparación de uno de los sitios web.

You MUST try to identify the organisms you see in your water sample by using the images and descriptions you find on the websites. Take a look at several of the websites before you decide what you think the organisms are. DEBE intentar identificar los organismos que ve en su muestra de agua utilizando las imágenes y descripciones que encuentre en los sitios web. Eche un vistazo a varios de los sitios web antes de decidir qué cree que son los organismos.

Reverse Image Search
You can also use your phone to photograph what you see in your microscope and use "Reverse Image Search" to find similar photos and websites that have similar photos. Go to Google Images and click the little camera icon to "search by image" then upload your photo to see what sites come up. This may help you find out what organisms you've discovered. También puede usar su teléfono para fotografiar lo que ve en su microscopio y usar "Búsqueda inversa de imágenes" para encontrar fotos y sitios web similares que tengan fotos similares. Vaya a Google Images y haga clic en el pequeño ícono de la cámara para "buscar por imagen" y luego suba su foto para ver qué sitios aparecen. Esto puede ayudarlo a descubrir qué organismos ha descubierto.

Esto es solo una imagen ... vaya a Google Images para usar esta función.

Once you think you've identified a microorganism you may search for other images or videos of it online to confirm your identification.  Una vez que piense que ha identificado un microorganismo, puede buscar otras imágenes o videos en línea para confirmar su identificación.

Also try to identify any organelles you can in the microorganisms you observe. You may see nuclei or flagella or other organelles. También trate de identificar cualquier organelo que pueda en los microorganismos que observe. Puede ver núcleos o flagelos u otros orgánulos.

If you use other website, please write them on the back of your "Identifying Pond Water" lab sheet.  Si usa otro sitio web, escríbalos en el reverso de su hoja de laboratorio "Identificando el agua del estanque".

A timeline of life.... 4.5 Billion years of evolution

A timeline of life.... 4.5 Billion years of evolution

Evolutionary Events and Geologic Time (Deep Time)

Once you've calculated the number of years  between each of the evolutionary events and the distance between each event on your timeline, create an accurate timeline including the number of MYA (millions of years ago) each event occurred.

Use the following images and links (
and others you find on your own) to find images to use as guides for drawing a representative diagram of each event on your timeline. (I included the first few which are more difficult to find... you can find the others on your own.)

Be careful to organize your timeline so you have enough room to draw images for each event... this is easy at the beginning, but very difficult toward the present day... events happen faster and faster toward the present.

This simple video does a great job of explaining what the Photosynthesis Equation means at the molecular level. - It's on YouTube, so it may not work at school.

Photosynthesis Virtual Lab - 

This is just an image... read the rest of the post to find the virtual lab.

In this lab you will be using a computer simulation to test out different variables to see how they affect the rate of photosynthesis.
En este laboratorio va a utilizar una simulación por ordenador para probar diferentes variables para ver cómo afectan a la tasa de fotosíntesis.

Use the handout to keep track of your experiments and your data.
Utilice el folleto para mantener un registro de sus experimentos y sus datos. 

Here is a much more advanced video that takes us deep inside chloroplasts to see what's going on in terms of actually moving electrons around.
