Teaching science lessons can be a bit complex due to some concepts that may need the teacher to help learners understand them better. This is because such ideas are abstract or need one to imagine them but are not tangible or directly visible, for example, the cells in organisms, the solar system, and others. Therefore, the teacher must use various teaching aids like pictures and video presentations. Also, science teachers can use PowerPoint for science-related learning presentations. Teachers looking for teaching aids for their science classes can visit to learn how to incorporate PowerPoint presentations in their teaching.

Here are some ways you can use PowerPoint for presentations in your Science classes:

To Act as Digital Laboratories

digital laboratories The various science disciplines involve experiments conducted in the lab so that learners can observe the reactions and results. For example, Chemistry has experiments involving mixing two or more substances and observing the reactions. For example, an acidic liquid can be added to a litmus solution to see the color changes.

Since it is not always to have a lab session, the science teacher can have PowerPoint presentations showing pictures for every step and the result or observations. This could make the students understand the concept better because pictures get committed to the memory better than oral descriptions. The good thing is that such digital labs can even be used for remote learning.

To Explain Abstract Concepts

Since such things can only be imagined, the teacher needs some aids to help learners grasp those concepts. Using PowerPoint to present such ideas in pictorial format help the teacher to explain those things more clearly for the learners to understand them better. Colored and well-labeled pictures would be best to explain such intangible things.

To Present Key Points for Lessons

For very long topics with many sub-topics, for example, the classification of animals, learners could easily get lost or not connect one idea and another. The science teacher can use PowerPoint presentations to list the main ideas so the students grasp the flow of the topic. However, as the teacher uses the slide presentations, they must ensure they do not put too much text. Lots of texts are boring and make the teacher resort to reading them, which further messes things.

Top Qualities of a Good Public Speaker

Employers and school managers use public speakers to trigger action in their organization. Public speaking is indeed a powerful tool to trigger the change in any organization. The problem, however, is that all public speakers are never the same. Some are more powerful and influential. This is why, when looking for an excellent public speaker for your audience, you should do some research.

Ensure that the public speaking coach that you hire has the potential of bringing the desired changes in your organization. The following are the qualities that you should look out for in an excellent public speaker coaching.


Anyone who claims to be a professional speaker needs to show this by exhibiting a high level of confidence. Research has shown that confidence is key to public speaking, and if your speaker cannot show any confidence, then they might even not be able to deliver any point.

This, however, does not mean that nervous people can never be great public speakers. They can if they find a way of beating the nervousness. One of such ways is to master the topic of discussion. This, therefore, tells you that if you find a nervous speaker, there is a possibility that they do not know much about the topic.

Passion is actually one of the things that drive people to greater heights. This, therefore, tells you that if a speaker is not passionate, they might not be able to make any difference to your audience.

But how do you tell whether or not a speaker is passionate about what they do? Well, it is straightforward. You need to observe how they talk to you. Their mastery of the language can also tell you more.

Good Voice Modulation

The voice of a public speaker can make people sleep instead of listening. So when looking for a public speaker for your audience, it is good to consider the voice. You need to find someone who speaks naturally. If the audiences realize that the speaker is talking in a voice that is rehearsed, there is a possibility that they will lose interest. You also need to make sure that the speaker is audible.

Short and Sweet

There is no need for talking for too long when no one is listening to you. This is why great public speakers would always want to keep it short and sweet. It is never a good idea to speak for a long time when you know that people are not actually listening to you.
