Water! Help from blogger Mia Peselman

By Anonymous
This week we started a new science unit on water! To start, the children brainstormed what they knew about water already. We then took turns acting out different activities you might use water for (brushing teeth, washing hands, swimming, showering, etc) 

Following this, the children got a chance to observe water in a cup, and then place a utensil in the cup and see how the water changed (or didn't change). They also placed an image behind the cup to see how the image changed. 


Mia's observations: When the spoon was on the far side of the cup it looked bigger and when it was closer to you it looked smaller. When the spoon came out of the cup the water level went down. 

The next day, we tried an experiment with a penny. We were trying to see how many drops of water the penny could hold. Mia's observations of the penny are below:

When you drop water on a penny until it fills up all the way the water falls off because there was no more room. If you were very careful, you can make a larger bubble on the penny.

We learned that the reason the water collects on the penny is due to surface tension. When there is too much water on the penny, the tension breaks and the water falls off.

                                        Here are some pictures of both activities!






















Ask your child you tell you about the following science terms:

Spotlight on the Middle School Fall Play

The Middle School After School Drama Elective will be presenting "The Trumpet of the Swan" in November and the students are hard at work staging, designing, creating and learning many theater skills that can be used during the performance process.  The following information has been submitted by our Grade 8 Student Officers who are members of the International Thespian Society (ITS) in the Rashi Middle School Theater Program.  As we get ready for our Fall show, we’d like to share a little bit about how we’ve been preparing for it in the tech booth. The lighting system is mostly up and running again as it was taken down at the end of last year for lighting maintenance. We’ve been working to arrange it in a way that is comfortable for the technicians in the Tech Booth to be able to program the lights for the show. We’ve also been gathering and designing the sound cues, and we’re getting ready to program them into the soundboard.  Ari I - ITS President - Class of '24 In the

Spotlight on the Lower School Show

This year I have had the opportunity to work with the lower school students on their wonderful After School fall show, The Twelve Dancing Princesses . I am the Production Assistant for the show. As somebody who has worked with Bonny in the Rashi School Theater Program for a very long time, I love seeing all the students show their love for theater every Monday. It brings me so much joy when I get to work with them and give them acting advice, the helpful tips and tricks that I was taught when I was younger by the student leader helping out. I love being able to work with the students and gain closer bonds with them as both a regular student and a role model. I choose to work with these students because I know how fun and exciting drama can be especially when you are a part of a younger age group. I feel like the older you get the more awkward or ¨embarrassing” certain shows and roles can be, which can affect your acting because it might be a little out of your comfort zone. This parti
