Preschool Class –
Today, we
continued our study of density – how tightly bound together molecules are.
We
demonstrated that salt water is more dense than tap water; therefore, some
items can float on salt water and not on tap water.
HOMEWORK: Find
something at home that sinks in tap water.
Do you think it will float in salt water? Draw a picture of your prediction. Bring the item to class and we will test it
on our salt water next week!
Level One –
Our chant to
practice: http://www.youtube.com/watch?v=2YyOUTZXaII
Today, we
once again demonstrated the property of water to stick to itself. We put drops of water on a penny and watched
the water form a dome before it overflowed.
We then
reviewed the datum that soap weakens water’s surface tension. We then tried to put the equal amount of
soapy water droplets on the penny as we did with tap water.
HOMEWORK: Think about what interests you for scientific
experimenting. Let’s talk about your
science fair ideas next week.
Level Two –

This week’s
focus: More on the Scientific Method
Your Learning Goal:
Think of
questions and form hypothesis that would be testable.
Video to
Watch and create your own notes:
Example of the Scientific Method
HOMEWORK:
Please think up one scientific question and a
hypothesis that you could develop from that question. If you have any problems, please feel free to
email me: libbymonte@yahoo.com.
I will not be able to answer any email on Monday
before class; therefore, please email me before then. Thank you.
Bring your
completed notes back to class on Tuesday.
Remember try to find the most important bits of data from the video and
record those in your science notebook. Please
also bring any questions you have about the videos.

Videos to Watch:
Conducting an Experiment Using the Scientific Method
You should have learned a bit more about experiments that
follow the scientific method.
If your experiment is conducted correctly, then another
person should ___________________________.
Why does she use four glasses and why does she repeat the
experiment?
Scientific Method – Myth Busters
Be able to identify the parts of the experiment.
HOMEWORK:
Please think up one scientific question and a
hypothesis that you could develop from that question. If you have any problems, please feel free to
email me: libbymonte@yahoo.com.
I will not be able to answer any email on Monday
before class; therefore, please email me before then. Thank you.
Please bring your video notes, questions and hypothesis to
class on Tuesday.
Scientist Assignment:
Where did your scientist(s) attend school? What was his or her scientific training?
