Dec 13 Set up decorations for Christmas concert and spent extra time working on our math probabilty presentations.


 * Dec 12**
 * Today we prepared our study notes on mass, weight, and gravity**


 * I found a very cool link to an applet where you can calculate your weight on other planets! Haven't you always wanted to do this?**

 * Dec 8**


 * Today we prepared for our Christmas Concert**


 * Dec 7**
 * 7K Today we will write our Topic 3: Mass and Weight study notes**
 * Check out this video!**

 * 7T Tody we will work on our Mass Mania and Wonderful Weight Lab**


 * Dec 6**


 * 7K Today we will be using the 16 page booklets we made from a single piece of paper (thanks to Amy for finding the youtube link that taught us this cool little book). We will be working on our Mass Mania Wonderful Weight lab and measure the mass of objects in the classroom using a balance. We will convert our measurements to kilograms and then use that value to estimate and calculate the weight of objects on earth.**
 * 7T Today we learned how to use balances and learned how to convert grams to kilograms.**


 * Dec 5**


 * Today we learned about the difference between mass and weight. We found out that Mrs. Kidd has a mass of 63kg and her weight is about 600N! Students also measured their mass and determined their weight.**


 * Dec 2**


 * Today we learned about forces. We learned about gravity and Sir Isaac Newton. We also discussed Einstein's theory of gravitational pull.**
 * We learned about how to measure force using spring scales.**
 * Dec 1**


 * Today we wrote our Topic 1 and Topic 2 quiz on structures. Please make arrangements to write your test as soon as possible if you were absent today.**


 * Nov 30**

Today we reviewed topic 1 and 2 for our quiz tomorrow.

 * Today we finished our topic 2 notes and began reviewing for our quiz on Thursday.**


 * Nov 28**
 * SCIENCE QUIZ FOR TOPIC 1 and 2 has been postponed until Thursday...thanks for the great examples and discussion in class. Your sharing of ideas helps us make real life connections to the concepts we are learning.**

7K Today we completed our Topic 2 notes and discussion on Describing Structures. Next day we will be working on a Topic 2 Review sheet and then we will be studying for our quiz on Thursday.

7T Today we learned about joints, laminations, fasteners and adhesives. We will be completing our Topic 2 notes on Describing Structures next day.

7K and 7T - today we will work towards completing our Topic 2 notes and discussion. Next week we will begin reviewing for our Unit 4 - Topic 1 and 2 quiz. media type="youtube" key="j-zczJXSxnw" height="216" width="317"
 * Nov 25 - Reminder: Topic 1 and 2 quiz coming up next week! Planned for Wednesday Nov 30.**
 * Nov 24**

7K and 7T today we will continue with our Topic 2 notes and discussion on describing structures: We discussed margin of safety, joints, fasteners and laminations.

post it on our wiki somewhere and we can show it and discuss your find in class!
 * Nov 23**
 * 7K Today we will begin our Topic 2 notes and discussion on Describing Structures.**
 * Reminder:** I have found some pretty cool videos links for this describing structures lesson but if you find something even better...

7T today we will work on our Golf Ball Bridge lab. Be sure to bring your bridge investigation from last day to class to help you with your design!

7K today we will be going to central office during science time to participate the the "Under My Skin" seminar. Don't worry, class! It's not about parasites;)


 * Nov 16**


 * Today we will work on our Bridge Basics Investigation**

 * in preparation for our Golf Ball Bridge Challenge**
 * Strength of Shapes Applet:**

[]
 * Characteristics of Materials applet:**


 * ...here is a preview of our bridge lab**
 * [[file:Golf ball Bridge.docx]] and [[file:Bridge Basics Investigation.docx]]**


 * Nov 9 and 14**




 * Today we will practice classifying types of structures**




 * We will analyze and compare a natural frame structure to a manufactured frame structure.**

See page 275 in your textbook "Frame it Activity


 * Picture from our Egg Structures activity!**



Today we will be learning about different types of structures:
 * Nov 8**
 * Natural vs. Manufactured structures**
 * Frame Structures**
 * Mass Structures and**
 * Shell Structures**

We will be using our knowledge of these structures in an egg drop challenge experiment where we design a structure to protect a raw egg as it undergoes a free fall due to the force of gravity.

Eggs-periment Handout:



Thinking outside the box for an egg drop challenge - you will love the creativity!
