Preschool Class –

Today, we continued our discussion of states of matter.  We reviewed and then learned about density – how tightly bound together molecules are.  Some items are very dense – like a rock.  Some items are less dense – like a cotton ball.

We demonstrated this concept by weighing the same amount of different matters.

HOMEWORK:  Find something in your house that is more dense than water and will sink in your sink or bathtub.  Can you find something less dense than water that will float on top of the water?  Draw a picture in your journal.

Level One –

Today, we practiced our prediction skills again and reviewed the surface tension of water.  We reviewed that water molecules like to stick together and this creates the “strength” of the water’s surface to support weight.

We demonstrated the “stickiness” of water molecules by watching water rise above the surface of a container before it overflowed.  We used our magnifying glasses.  Yay!

We had a lovely time with classmates sharing their science treasures.  Thank you, Amelia, Ruby and Charleigh!

HOMEWORK:  Show your parents or sibling how water rises up over the edge of a glass before it overflows.  You can predict how many drops will hold together until the glass overflows.  Test your prediction.  Have fun!

Kindergarten Class –

Today, we reviewed the three states of matter – solid, liquid, and gas.  We reviewed the traits of these states.

We changed the state of matter in class.  We melted a candle thus turning solid wax into a liquid.  The best part was turning chocolate chips into a melted liquid and chilling it back into a solid.

Homework:  Find some matter in your house that can change from a solid to a liquid, or liquid to solid, or any change of state.

Please draw a picture of that matter in both states in your Science Journal.

Level One –

Our chant to practice: http://www.youtube.com/watch?v=2YyOUTZXaII

Today, we practiced our prediction skills. 

First, we learned about the surface tension of water.  We conducted a few demonstrations about water tension.  After we made several observations, we began and demonstration but stopped halfway.  Each student made a prediction about the outcome based on our prior knowledge.

HOMEWORK:  Find something at home that you think can be held up by the water’s surface tension.  Test your prediction.

Preschool Class –

Our students are still focusing on the three states of matter.  Today, we learned some properties of each:

Gases: molecules far apart, usually can’t see gas, takes the shape of its container

Liquids: molecules close together, visible, takes the shape of its container

Solids: molecule together tightly, visible, usually holds its shape

Your young scientist was presented with a Science Journal to record things he or she notices in their world.

We learned about tally marks today.  They may need to practice this with you or at least get a refresher.

HOMEWORK:  Watch a friend, parent or pet for one or two minutes.  Record how many times he or she blinks using tally marks.   If your child can write, he or she can spell out the name of the person or pet.  A drawing of the observed one is totally okay.

Level One –

Today in class, we reviewed observe and infer.  There should be a handout pasted in your student notebook. 

If you get confused or are unsure in any way, please email me: libbymonte@yahoo.com.

HOMEWORK:

1) Continue to practice the chant: http://www.youtube.com/watch?v=2YyOUTZXaII

2) Observe a place, person or animal.  Record three factual observations – something that is a fact, not opinion.  Then, make one inference from all the information that you have.

(Example:  I see a neighbor’s house at night.  There are no cars in the driveway.  There are no lights on in the house.  There is a package from the postal worker on the front porch that has not yet been picked up.  Those are my facts.  I will infer that my neighbor is not home.)

3) Please record this in your science notebook and bring it back to class.

This week’s focus: Creating a Scientific Question

Your Learning Goal:  What is a good scientific question?

VIDEO:  A Testable Questions (Very short video with examples of Testable Questions)

http://www.youtube.com/watch?v=zeJRLHtCCBg

There are notes from class and a homework assignment.  The notes should be pasted into your science notebook.

HOMEWORK:  Compose one bad scientific question for each of the points from your notes.  Example (Good Scientific Questions are not about opinions.  My bad question is:  Is hot chocolate the best drink for the winter?)  (Good Scientific Questions can be proven true or false.  My bad question is:  Do aliens live on Mars?)

When your bad questions are complete, think hard and create TWO scientific questions about which you could create an experiment or do a test.

If you are not sure and you want to chat with me, please email me any time – libbymonte@yahoo.com.

Bring your notebook back to class on Tuesday.  Please also bring any questions or cool observations that you would like to share.

This week’s focus:  Testable Questions

Learning Goals: 

·       What makes a good scientific question?  

    Be able to list several do’s and don’ts. 

·       Continue to explore a note-taking format that best suits your learning style.

·       Continue to find out information on your scientist.  Try to find out what she or they did specifically in words that you and all of us will understand.  Please think about a good scientific question that she or they would have asked.  Think of good question that would be testable.

Preschool Class –

Let’s get ready for the Science Fair!  Yes, your young curious student can prepare a display for the HLACNY Science Fair.  In class, we will continue to do experiments and gradually learn how to ask a good question, how to make a test for that question, and then make conclusions.

I have found a video series – Dino Dan by Sinking Ship Entertainment – that exposes the youngest scientist to the scientific method in an easily digested format.  The cool, colorful dinosaurs are an added bonus. These videos are in our library system and I strongly encourage you to share these short videos at home with your student. 

Today, we learned the three states of matter – solid, liquid and gas.  We played a game identifying substances correctly.  We captured the gas created when a liquid (vinegar) and a solid (baking soda) mixed to create a gas (carbon dioxide). 

Here is a video for your student to watch for fun on the three states of matter: http://www.youtube.com/watch?v=btGu9FWSPtc

Level One –

We are going to explore the scientific method in preparation for the upcoming Science Fair.  Yes, your child can perform a very basic experiment, learn something fun, and present it at the Science Fair. 

Here is a cute chant that we are going to learn in class:

http://www.youtube.com/watch?v=2YyOUTZXaII

Please have your student practice the chant at home.  

The site below that will give you an overview of what we will be learning.  Though the steps are a bit different from the chant, the material is the same.

 http://www.smartfirstgraders.com/scientific-method-for-kids.html

Your student will be exposed to some new vocabulary.  Each will be provided with a home study sheet weekly.  It is hoped that you will assist your budding researcher with his or her homework.

After we have completed our study of the scientific method, I will assist these eager scientists during class time to find an experiment or project that will meet their interests and age level.  If you find one with your child, that is no problem!

Homework:

• Review chant several times.
• Sit and observe your backyard for ten minutes.  Write down what you see or draw pictures.  Bring that back to class to share.
