Experiment: Measuring the weight of masses

Experiment: Measuring the weight of masses

(0)
This video is aimed at pupils at KS3/4. It shows a video of an experiment where 100g masses are put onto a forcemeter, calibrated in newtons. It allows the measurement of the force for each mass. There are questions to focus pupils on the relationship between the masses and the weight. It can be used as a graphing exercise to calculate the value of the constant ‘g’. There is a PowerPoint slideshow to help focus the activity if used in a classroom. This resource forms part of a sequence with two other resources: This resource https://www.tes.com/teaching-resource/experiment-stretching-a-metal-spring-12952559 https://www.tes.com/teaching-resource/experiment-stretching-a-rubber-band-12952565

Experiment: Stretching a metal spring

(0)
This is a video aimed at pupils in KS3/4 that shows an experiment of a metal spring being stretched. The stretching happens when masses are added to the end of the spring. There is an introduction the experiment, which aims to help pupils understand the most important ideas. After each mass is added the spring, the video zooms in on the scale to allow pupils to read this. This can form the basis of a graphing activity to find the relationship between the masses added and the extension of the spring. There is a PowerPoint slideshow to help focus the activity if used in a classroom. https://www.tes.com/teaching-resource/experiment-measuring-the-weight-of-masses-12952546 This resource https://www.tes.com/teaching-resource/-12952565

Seafloor Spreading - graded questions

(0)
This activity contains a powerpoint with graded questions & answers and matching pupil activity sheets, designed to be used at the end of a lesson and/or the start of the next lesson to review previous learning. The questions are based on OCR 21st Century Science Specification, although could be used with other exam boards. Clicking through the show reveals answers one a time. There are two slightly different activity sheets for differentiation - one has key words, the other without. These reduce to A5 easily, the ideal size for most pupils. Please note grades are approximate.
Home experiment: Infrared remote control

Home experiment: Infrared remote control

(0)
In this video, which is aimed at KS4 pupils, you can see an infrared remote control. The remote control is pointed at the camera and a button is pressed. You can see the signal from the remote control, even though it would be invisible if you were to look at it with your eyes directly. The camera used is sensitive to infrared and so shows it up on screen. Pupils may be able to repeat this experiment at home, although some cameras include infrared filters to reduce glare from sunlight, so it may not show up properly. This resource is part of a sequence with the following three other resources: EM spectrum grid https://www.tes.com/teaching-resource/resource-6341301 EM spectrum sort cards https://www.tes.com/teaching-resource/resource-6341302 This resource UV lamp and washing powder https://www.tes.com/teaching-resource/resource-12952892

Experiment: UV and washing powder

(0)
In this video, which is aimed at KS4 pupils, washing powder is shown under an ultraviolet lamp. This shows the fluorescence from the washing powder as the UV light is absorbed and visible light is emitted from the powder, making it appear much brighter than the washing powder would be if it was simply reflecting the light.

Experiment - melting ice & freezing wax

(0)
In this video, which is aimed at KS3 pupils, a video is shown with changes of state of matter for ice and wax. The melting ice takes place on a two surfaces, a conductive surface (aluminium pan) and and an insulating surface (wooden chopping board). The video shows how the time of melting differs for each surface. The experiment also shows wax freezing on the same two surfaces. Pupils can compare the times and suggest explanations as to why the times differ. The video includes prompts to support their thinking.

Video Experiment: A pair of forcemeters

In this video, you will see an experiment where a pair of identical forcemeters are pulled apart. There are questions that focus pupils on the force pair interaction. It asks pupils to make predictions, then shows what happens in the experiment.

Thinking About: A hot-air balloon rising

(0)
In this video, which is aimed at KS3/4 pupils, a hot air balloon is shown rising. Pupils are asked to describe and explain what they see and are reminded that there is a heater in the balloon. This can be used as part of a lesson about density, where pupils can use the idea of the hot air being less dense than the cooler air around it, therefore causing the balloon to float.

Experiment: Tangerine mystery

(0)
In this video, which is aimed at pupils in KS4, a tangerine is shown. Firstly it is weighed, then is shown floating on water. Then it is peeled, weighed again, and then pupils are asked to predict what will happen when it is placed in water. There is an element of surprise in the video that aims to help challenge preconceptions that they might hold.

Experiment: Making a fruit 'battery'

(0)
In this video, which is aimed at KS3/4 pupils, a fruit ‘battery’ is shown. The ‘battery’ has been made with different pairs of metals for the electrodes. Readings are shown in the video for the potential difference (voltage) across the electrodes for each pair. Pupils can then consider the connection between reactivity of the metals and the results of the experiment.

Objects in Space sort cards

(1)
Key words: Universe, Galaxy, Solar system, Sun, planet, asteroid, constellation. This is a sort card activity and powerpoint show to support the task. It gets students thinking about objects in space. The powerpoint show comes in two forms, with or without the word constellation. The addition of the constellation card adds a real opportunity for cognitive conflict and helps iron out a preconception of what a constellation is.

Greenhouse Effect starter - Draw what you think

(0)
A simple but effective activity to establish prior knowledge at the start looking at the topic of the Greenhouse effect. Learners can be encouraged to use scientific vocabulary and ideas. It is a great way of finding out how they think a greenhouse works before looking at the atmospheric effect. Works well when working in small groups (e.g. 3) on a large piece of paper. Really helps them to think when they are asked to justify their reasoning. Right-click then 'save as&' the web link to download the PowerPoint show.

Maths Skills - Units - SI Units Starter

(1)
These are a sequence of powerpoint shows designed as an instant engagement task (rolling on screen as learners enter the room for immediate engagement with learning). Learners write down the the SI units for the named quantity. More able learners could provide SI units in terms of fundamental base units. They are essentially the same task (with rearranged slides) but get progressively more demanding (as the changeover of slide gets faster) as the numbers in brackets increase. Start the students with (1) and then as they get faster, use the more demanding versions
