As a wrap up students were tasked with building a Marble Rollercoaster using pool noodles split in half. They were able to challenge themselves by adding various simple machines, gaps/jumps in the rollercoaster, making tunnels, label and understand kinetic and potential energy transformations and stay within a budget. I have attached pictures of the designs students came up with below.
Any students who would like to work on some mental math doing some practice mobiles using the Solve Me Puzzles website I have added the link below.
The Mechanical Systems Quiz will be tomorrow in class. It is a mix of multiple choice, matching, short answers and problems involving calculations.
The Mechanical Systems Review Quiz will be on Tuesday, May 21. I have attached a review that students can do if they need some guidance while studying. I will put the key up on Monday for those wanting to check their answers.
The unit quiz is tomorrow for these topics. Some review questions for those who would like some extra practice.
This week students have been working on Pythagorean Theorem. We started off my reading a story and then having a silent discussion about the story of the Theorem. We followed this by showing some proofs and building some simple right triangles. I have attached some questions for extra practice tonight.
We have also continued our work with Efficiency. Some questions that we did in class today include what has been attached below.
This week we started a new unit in Science, Mechanical Systems. We touched briefly on this unit when we were doing our Grade 8 Mobile Escape Rooms. This week we reviewed Simple Machines and have started to cover the concept of Work and Mechanical Advantage.
On Tuesday there will be a quiz on Linear Relations. Students are expected to be able to complete a table of values, graph using 4 quadrants, derive a formula from table of values and be able to write expressions using word problems. I have attached some of the word problems we worked on this week in class.
All students who are away for Band Camp on Tuesday and Wednesday will be making up the Quiz Thursday at Lunch and will be allowed to also continue during the flex period. Bring your lunch.
Some extra practice for anyone who would like to study some more over the weekend.
Students are working on various Light and Optics Topics. Students will have class time this week to both work on the presentations and present. I have attached all topics below in case anyone needs it.
We have continued with some new topics in Light and Optics. This has included colour, the wave model of light and revisiting the Electromagnetic Spectrum.
For the wave model of light students are expected to now both what a wavelength is, and parts of a wave including crest, trough, rest point, amplitude as well as what frequency is and how to calculate frequency.
We also revisited the Electromagnetic Spectrum. Among learning the different types of waves that exist we also discussed how Gamma Rays hold an incredible amount of energy and that they are not green as we cannot see them and being inundated by a massive amount Gamma Rays would not lead us to becoming The Hulk but rather becoming The Not Alive.
Finally students were given some time to explore white light, prisms and laser pointers. They were all able to show how white light is indeed composed of all the colours of the rainbow. Laser pointers were used to reflect and making some laser mazes with mirrors.
Students exploring various light properties.
Our best demonstration of white light being a combination of all the colours of the rainbow.
We will be moving onto Linear Relations next week on Tuesday. A reminder that Monday we will be having a final Linear Relations Quiz. Students will need to know Distributive Property, combining like terms and solving equations that have variables on both sides.
