Grade 7 Physics Lessons for Spring 2023
Assessments: to be arranged
Test date: 2.5
| Week number | Starting date | Lesson content | Lesson resources and links | Homework |
| 2 | 9.1 | Introduction to physics this year. | Information sheet The Finnish sauna - how to survive it..... | .Read the sheet you were given in class and then complete this form |
| 3 | 16.1 | Understanding heat and temperature - what are they ? How are they measured. Temperature scales The particle model. | How does heat move within the sauna ? Why are the benches wooden, and not made from metal ? Why do Finnish children stick their tongues against cold metal posts ? States of matter introductory video The Particle Model diagram Explaining properties of solids, liquids and gases Lesson notes | Voluntary homework - a couple of videos for you to watch if you are interested How many states of matter are there ? Thermal expansion Also, think about why birds' legs don't freeze when they stand for ages in freezing cold water. |
| 4 | 23.1 | Heat and expansion. How a liquid in glass thermometer works. Measuring temperature. | Expansion when heating Reviewing the particle model Why materials get bigger when they get hotter. Looking at thermometers - liquid in glass; digital. A temperature measurement of water in the school. Lesson notes | Complete this form Note ! If you missed the lesson, do not do the homework but make sure you: watch these videos Temperature scales How an old thermometer works and in your notebook explain how the thermometer works. Drawing the particle model diagram too may be useful for the test later. |
| 5 | 30.1 | How we record results and data Understanding heat transfer | Reviewing the experiment from last time Recording data - rules! How heat energy moves Conduction of heat along a bar Conduction animation -internal energy Convection particle video Radiation video Quick video clip explaining convection currents Lesson notes | This form |
| 6 | 6.2 | Reinforce ideas about heat transfer Using the scientific method for black/white object experiment | Fluffy bird Heat loss from a human body in cold weather Do black objects cool more quickly than white objects ? Thermal image Radiation video Investigation planning sheet Using the scientific method Lesson notes | Spend some time going through the notes, and the work you have already done. In your notebooks, write down any questions you have about the work - things you do not understand etc. We will review these next lesson. |
| 7 | 13.2 | Identifying variables Carrying out the experiment | Review of questions from the homework Lesson notes Results from last lesson Understanding variables What are variables. powerpoint presentation | Read this page on how animals keep warm in cold conditions. Then choose ONE of the 15 methods and explain how it works in your own words, but using the ideas of conduction, convection and radiation. This is not easy as there are many different explanations, so just try to keep it simple. The easier examples are numbers 3,5,7, 9, 11 and 13. Spend a maximum of 20 minutes on this task. Send your work to me in an email or as an attachment. karin.parker(at)eduouka.fi |
| 8 | 20.2 | Variables | Results from last lesson Lesson notes What are variables. powerpoint presentation | Over the next week, pay attention to your outdoor clothing and think about how it keeps you warm. How does it use conduction, convection and/or radiation ? No need to write anything - but it would be useful if you did. |
| 9 | 27.2 | Planning the investigation | Investigation instruction sheet Assessment criteria IB version Assessment criteria - student friendly version for grade 7 Explanation sheet for the writing frame - bilingual .png) Writing frame (pdf) Writing frame as google doc- please save a copy or download it | It's ski break, so no homework BUT all of you have projects on going, so if you want to spend time on these - like 20 minutes - that is fine. But this is not compulsory! |
| 11 | 13.3 | Doing the investigation | Make sure that you have completed the plan/method section of your investigation | |
| 12 | 20.3 | Completing the investigation | Lesson notes | Complete the investigation - it is due at the start of next lesson |
| 13 | 27.3 | Introducing waves. | What are waves ? The electromagnetic spectrum. The dress Resonance and shattering a wine glass | No homework |
| 14 | 3.4. | Wavelength, amplitude, frequency. Units. Light in nature Light pillars, YLE November 2022 Why is the sky blue ? What is colour ? Primary colours of light How we see colour Short video A longer video if you would like to know more. It is old but valid The dress How light interacts with surfaces - absorbtion, reflection, scattering Lesson notes | When you see some beautiful natural colours in the sky, try to work out what causes them eg aurora, sunset, halo, rainbow. Take a photo of it and email it to me to say how amazed you were by its beauty. No deadline- whenever you want. Maybe even in 20 years. | |
| 15 | 10.4 | Reflection of light | How light interacts with surfaces. Rules for drawing light rays Law of reflection Lesson notes | Reflection from a curved mirror. Take a shiny metal spoon and look at your reflection from the spoon when it is concave side up and then convex side up. In your notebook describe the reflections eg bigger, smaller, upside down, left-right reversed. Does it matter how far away you are ? |
| 16 | 17.4 | Reflection from curved surfaces. Refraction | Lesson notes | Study for the open notebook test in week 18. Get your notes sorted out. How to study for the test - click here Here is a video I made for last year's groups to help them study for the test. |
| 17 | 24.4 | Studying for the test | Lesson padlet Lesson notes Lesson resources - the car turning/explaining refraction | Same as last week: study for the open notebook test in week 18. Get your notes sorted out. How to study for the test - click here. Here is a video I made for last year's groups to help them study for the test. Here are links and PIN numbers to some of the Kahoots you have done this term: Heat transfer 08410999 Visible light 05931543 Variables 05054132

| 18 | 1.5 | Test | ||
| 19 | 8.5 | Refraction and reflection | What is refraction ? Refraction through curved prisms and lenses. Total internal reflection. Lesson notes | No homework |
| 20 | 15.5 | Sound | Frequency and musical notes. Hearing. If you missed the lesson, watch this video. There are no lesson notes. | No homework |
| 21 | 22.5 | Sound - digital and analog Lesson notes Ultrasound imaging Decibels - comparison of loudness Measuring decibels - mentions logarithmic scales |
