Undoubtedly, rather breath-taking paintings can be created in ink. Yet, the picture that appears on the leaves of a white carnation as a result of an intriguing experiment certainly competes with those paintings. What does the vascular tissue consist of? What do the terms "xylem" and "phloem" stand for? What do they look like? What are vascular bundles and what types do they have? How can they be examined? The following lesson plan provides ideas for teaching plant water transport.
1. Let's introduce the parts of the vascular tissue and the basic idea behind their operation.
Tracheophyta both transport water and water solutes in tubular formations. The vascular tissue can be divided into two parts, namely the xylem and the phloem. While the xylem transmits such ions that become dissolved in it, from its root towards all the other organs, the phloem transmits organic materials having been dissolved in water from the leaves towards all the other organs.
Is it possible to teach ethical behavior? Apparently, this is an existing and legitimate suggestion. Now let’s try it! With Ethics Unwrapped University of Texas makes an attempt to teach such basic ethics for students that are useful when coping with the challenges of the business world. Certainly, economic crises of previous years pinpoint how crucial it would be to live up to ethical standards in the business sphere. Had it been for conforming to basic ethic norms, the whole American credit crisis could’ve been prevented.
Famous people – no matter if historical figures or contemporary celebrities – never cease to impress us. mozaTool Hall of Fame helps students to find out more about them with just a couple of clicks.
Though the Hall of Fame app including more than 1,000 famous people can be found among history tools, it can be used in almost any classes, just use the filter panel to narrow the list of people according to your needs.
Click on the clock icon in the right bottom corner of the list view window to filter by time period. The slider under the timer enables you to produce a historical who’s who for a time period as short as 60 years, which can be used e.g. for exploring the contemporary peers of the historical figure/artist the students are just learning about.
The course book has always been an essential part of the teaching-learning process. It is the storehouse of information used both to learn and to teach from. If I take a course book I can work with all the information gathered in it. However, this in itself is not satisfying any longer as students look out for something more and teachers are also eager to provide them with more.
Previously, fitting all the whiteboard, the slide projector, the audio and video playback equipment in a lesson plan called for the teacher to do a thorough and lengthy preparation. To combat this problem, mozaBook offers a tremendous opportunity. All the additional content with which we wish to boost our lesson, for what up until now we had to use various tools at the same time, can now be collected in one place.
Pictures, sounds, presentations etc. prepared in mozaBook can be directly related to the lesson's material. Moreover, each element can be attached to the adequate lesson plan in the course book and can be launched right from there, whenever needed.
I've found a gripping article the other day about researchers who had examined the network system of the Greek epic poem The Odyssey, mapping 1700 connections of 342 characters. Interestingly enough, they have found that the network system of the epos is very similar to that of the network systems of Facebook or Twitter.
According to the writers of the article this indicates that the poem was probably based on real events. They studied Beowulf and Iliad in a similar manner and with the same results. However, the Irish epic Tain Bo Cuailnge did not pass the test.
Therefore, I have searched for software that is free of charge and which can be exploited in visualizing networks. The solution turned out to be the open source application Gephi, which makes us pro network analyzers. We can settle the intersections one by one but it is also possible to load an Excel file and then there are several ways of visualizing the network. Although, what is it good for? We can use it to make sociograms in the class but also to discover the relation system of an ecosystem.
There is an entertaining (and extremely addictive) game based on Google Street View called GeoGuessr. Our task is simple: we are dropped off somewhere in the world, at random, and we must guess on the world map in the top-right corner where we think that place could be.
In GeoGuessr, we can walk up and down the area with the Streetview app until we discover some kind of signal (such as signs or people). I used it in one of my lessons to practise intelligent speculation and teach forming conditional sentences.
