Summer Science
How can you keep students thinking about science over summer break? We
suggest offering them science-based activities that they can do on their
own without much expense or equipment. We’ve gathered some for biology,
chemistry, earth and environmental science, and physics that fit the
bill. Check them out at the link below.

Rat Dissection, External Exam
If you are currently dissecting rats in your lab, don’t miss the
opportunity to address comparative anatomy. We’ll show you how to start
with a thorough examination of the rat’s external anatomy that helps
students gain insight about this animal’s habitat, behavior, and
relatedness to humans. Click the link below to begin the exploration. |
Proper Storage of a pH Electrode
With the end of the school year approaching, it’s time to start
preparing your lab equipment for summer storage. The professionals at
Hanna® have some tips for storing and maintaining pH electrodes. Given
proper care, electrodes will have optimal service life and yield
accurate readings. Visit the link below for the basics. |

It’s Summer Break, but My Classroom Is Alive!
It’s time for summer break and your classroom is filled with critters.
No, we’re not talking about the students that liked biology so much they
can’t bear leaving. We’re talking about the critters in your aquarium,
terrarium, and petri dishes. What do you do with them over summer break?
See our expert’s suggestions below. |
Order Now, Get It Later!
Sometimes delayed gratification is a good thing. For instance, you want
to order your fall supplies now, but don’t need them delivered until
August. No problem; just give us your preferred delivery time when
ordering by phone, fax, email, or Web. When August rolls around, you’re
set. Click the link below to learn more. |

Which One Melts Faster?
Here’s a fairly quick and inexpensive way to demonstrate heat transfer
(conduction) and the difference between conductors and insulators.
|
1. |
Divide your class into groups and let each group examine a block of
aluminum and a block of plastic. |
|
2. |
Ask each group to form a hypothesis about which ice cube will melt
faster; one placed on the aluminum block or one placed on the plastic
block. (Most groups will say the one on the plastic block will melt
faster.) |
|
3. |
Test the groups’ hypotheses by placing each of the 2 blocks in its own petri
dish, and then placing an ice cube on top of each block. The ice cube on the
aluminum begins to melt immediately, and you can hear the oohs and aahs
coming from all over the room. |
|
4. |
Use a stopwatch to time the process. |
I let the kids touch the aluminum and plastic during the demonstration and they
are always amazed at how cold the aluminum gets while still melting the ice. To
conclude, I have students identify the conductor and the insulator, and then
write a statement about what they have learned.
