What can you do today for Earth Day?
Enjoy the Earth's beauty. Go for a bike ride or walk. Play a game outside. Time spent outside is time not spent using electricity or other energy sources. It's a gorgeous day today. Here are some things happening around the city:

Science
On Friday we conducted an investigation involving the CHANGES OF STATE. How did we change the states of water? The answer is all about heat or energy. When we add heat, we "excite" the particles in matter. They begin to move faster and in the case of a solid, they lose their fixed shape and change to a liquid. In the case of the liquid, the particles move even faster, spread apart, lose their fixed volume and change to a gas. The same thing happens when you remove heat (make things colder). The particles slow down and are closer together. Question for Tuesday (tomorrow we have track and field try-outs), why were there water droplets on the BOTTOM of the pie plate? Where did they come from?

There are some great video clips on the carousel (click the snowflake on the Board website) in grade 5 S&T.

Can you come up with 1 - 2 examples for each change of state? For example, frost on the grass in the fall is an example of deposition. The water vapour (gas)  in the air hits the cold grass, and changes of ice crystals (solid).

Math
Our times tables quizzes continue next week. KEEP PRACTICING. We have 7 students who have successfully answered 50 questions in about 3 minutes. By the end of the week, I predict the number to be much higher. Scores are definitely heading in the right direction. Be proud of your improvement Knowing your facts fluently will be such a help in math as you get older.

Here are a few grade 4 word problems for review:

Reminders:

• Track and field try-outs tomorrow (Monday). Although the weather forecast is warm, the morning will still be COLD. Dress in layers (sweatpants, sweatshirt, gloves hat, jacket), bring your water bottle,  gym clothes (underneath), running shoes and extra snacks to eat. All that physical activity outside will make you hungrier!
• Grandparents Day on Thursday
• End of the year field trip permission form and money. We have 6 parents who have requested to accompany us on the bus. Parents will be chosen by lottery. If more spaces become available, we will let you know. Thank you for volunteering!
