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)
