Work to be completed during the week commencing 4th May 2020.
All work is available via remote access for the school. It can be found in samples\science\working from home.
Food webs For ecosystems to function they need energy; and we can see how this energy moves through ecosystems with food chains. Make a start by watching this video then complete the work on the school shared area.
This week we are going to investigate catalysts in more detail and how they affect chemical reactions. We have already discussed catalysts when we looked at factors which affect the rate of reaction. Use the PowerPoint and this video to find out how catalysts work, then complete the worksheet and research task.
Secondly, we are going to learn about limiting and excess reactants. Start by going through the PowerPoint to learn what these terms mean. Then higher students need to watch this video and have a go at calculating which reactant is limiting the reaction. Remember that if you are stuck watch the video again and look through the worked examples on the PowerPoint and worksheet.
Continue following the on-line lessons. This week’s lesson is on Forces and Energy.
You can download the worksheet from the link in the video.
