Here is a picture of it in the first instar stage.

Cabbage White Butterfly Eggs are here!

We just received our Cabbage White Butterfly Eggs before break and have placed these on the radish leaves.  We should see the larva emerge soon!  Here are the eggs under the digital microscope.

Some of you bean plants did not grow as expected.

You may use this image as and example of growth and leaf structure.

Friday December 12th- Parts of a Flower.

Students started to look at flowering plants today to understand the different structures in a flower.  This will allow them to begin to classify the plants into the categories of perfect or imperfect which links to the ways they can reproduce.  

They took pictures with our digital microscopes and took cross-sections of the pistils of some plants.  

Here are some of the images they took.

Celestron Digital Microscopes

This week, students got to explore using the new Celestron Digital Microscopes. These microscopes were purchased with grant money awarded to the 7th Grade Science teachers by the Yarmouth Education Foundation (Thank you YEF!). Here are some shots students took of everyday objects. Can you identify any?

Wow Bugs!

Today the students were introduced to a parasitic wasp, the Wow Bug.  

Here are some images at scanning and low power.

Starting to use Hand Lenses and Magnification

Today our students revisited their definitions of "What does it mean to be living?"

After that, they moved onto using hand lenses.  They studied text in their book as well as pennies to try to find distinguishing marks.  Many were able to locate initials of the artist who created Lincoln's portrait. 

 The rest of this week we will explore light compound microscopes, how to focus into a specimen and what a good scientific sketch is composed of.
