25 Strangest Geological Formations On Earth

Of the 25 strangest geological formations in this video, which 3 are your favorite, why, and how did they form?

Leaf Classification

What type of leaf is #1, #2, and #3?  What are some ways other than by vein pattern can you classify leaves?

Pink Sand Beach

Time for some blog homework 6th grade!  Read the article linked below and explain why the sand on this beach is pink.  Pretty amazing right!?!

Wheat Seeds Switch

What differences did you notice between each of your plants?  How did plants always grown in the light compare to the ones switched to the light?  How did plants always grown in the dark compare to those switched to the dark?  What conclusions can you make about plants from this experiment?

Wheat Seeds

First blog post of the year!!!  Woo hoo!!  Hello awesome fifth graders.   Please use the comments below to describe the differences between wheat seeds grown in the light and seeds grown in the dark.  Explain what you think is happening to cause these differences

Heating Earth Materials

How did the temperature change differ between the soil and the water? 

Small Intestines and Kidneys

What was the approximate length of the pig's small intestine?  What 2 portions of the kidney are being pointed to by the probe?

Crater Impact!!

What variables did you test today?  How did your variables affect the size of the crater produced?

Pig Dissection Day 2

What parts of the digestive system were you able to identify today?  Describe each generally.

Pig Dissection Day 1

What observations were you able to make about the external anatomy of your pig?  Is your pig a male or female?  How do you know?

Sheep Eye Dissection

Identify and describe the parts of the eye pictured here.  Well done today BTW.  You guys rock!!!

Chemistry in a Bag

What were you able to determine by doing the experiments in a bag that you were not able to determine by doing the experiment in a cup?

Chemical Reactions

What were some of the products in today's reactions?  Was your hypothesis support or not support by your observations?  Which reactions were exothermic?  Was does that mean?

Nature Walk

How did having a dichotomous key help you to identify the trees on our walk? What made it difficult to identify the trees?

Classifying Leaves

1. Why do scientists classify organisms?
2. How do you write a correctly punctuated scientific name?
3. Why don't we just use the English or common name for organisms in science?
4. Recall the leaves you classified. What are three leaf traits or characteristics you used to classify the leaves?

Planet and Star Size Comparison

Saturated Salt Solution

How many grams of salt did it take to saturate 50ml of water?  What does saturated mean?  What did we use as a solute?  Do you think the water could hold more salt if the water was heated or cooled?

Natural Selection Graphs and Analysis

For the Natural Selection Lab, make graphs for all of your data.  If you did not finish the lab, make prediction graphs for the parts you did not finish and explain why you predict these results.  For your analysis, explain the results of each simulation, to include the questions asked on yesterday's blog post.  Include how this activity was a representation of actual events.  Also include the limitations of this activity (for example, how could you have manipulated the results)

Natural Selection Lab

How did the color of the environment (paper) effect the population (macaroni)?  What happened after several generations?  What do you predict will happen when you use white paper?  What do you think would happen to these species if there were no predators?  What would need to occur for speciation to occur?  How does this activity relate to evolution, natural selection and the fitness of a species? 

Cracking Your Genetic Code Response

What do you think are the benefits and disadvantages of knowing the contents of your genome? Would you want to know your chances of getting a disease that you could do little about (like Huntington's disease)? What would be the consequences of knowing? Do you think those consequences out weigh the benefits? Would you do things differently if you found out that you would get the disease? If so, what would you do differently? If not, why?

Your response should be a minimum of 250 words and answer all of the above questions. Responses should show thoughtful reflection. I recommend that you copy and paste your comment from a word document just in case it erases (so that you do not cry yourself to sleep). You are welcome to turn in a hard copy. This will replace a test for CH 14 and will be worth 50 test points.

Layering Liquids

Why were you able to layers the liquids in today's lab?

Salt Concentration Lab

Explain how it is possible to determine the relative concentrations of 3 unknown salt solutions.

Transcription and Translation

What is the role of RNA polymerase in transcription?  What is the product of translation?

Science Olympiad Practice

Nice work completing your first prototype for your wheeled vehicle!

Koolaid Concentration

What were the solute and solvent in today's lab?  Which solution was most concentrated?  Which was most diluted?  What caused solutions to be more concentrated?

Salt Solution

How were you able to determine the mass of the salt in your salt solution?  Was this a direct or derived measurement?

DNA Models

Separating a Dry Mixture

Banana DNA

Why did we add each solution to the banana?  Describe what the DNA looked like.  Do you think it would differ in appearance if we used a different fruit?  Why/why not?
