How to Create Animations for your Science Video Using Powerpoint: Part One


In this tutorial i will show you how to
create simple but effective animations with PowerPoint that can be exported as a movie file for use in your video projects. OK, so let’s take a quick quick
look first at a couple of animations that I did in PowerPoint. The first one you see here…. let’s play
it uh… this shows the oiling of a wetland. And the oil uh… here is floating on the water surface and now
it’s soaking into the ground. the plants die and the soil collapses. Okay that’s a very quick simple example. Here’s another one showing the concept of subsidence and let’s play it and what this is going to show is a skyline the city as the uh… soil that has accumulated compacts and consolidates, subsidence occurs. and i wanted to relate that to sea-level
rise and so I continued with showing what causes the increase in the ocean surface and then I wrapped it up by showing how subsidence and sea-level rise combined to equal the total submergence that an area experiences. So how did i create these in PowerPoint? Let’s take the subsidence example to illustrate. Close these windows out. and let’s open up uh… my file that i created and PowerPoint. Okay, first i decided on the sequence of
steps and i created a basic diagram to begin the sequence. and this case i wanted to show a land platform that would sink over time in relation to
the water level. the ocean level And this is easily created with the
shape function by selecting the rectangle shape here and that’s it; that’s all i did in this case and so i have a rectangle here
representing the soil platform, the land
platform and another rectangle representing the
ocean I next I created a city profile by again using the shape function to create the buildings. the rectangles and triangles used to create the roofs. And it’s important to group called the
components of a feature that is going to be moving
together so that they all move together in succeeding slides and so you can see
that all these different components in this grouping; they’ve all been grouped. uh… up here. If you look up here under arrange, you see that they are grouped and i can ungroup if I want but we want them grouped. okay so now when I move this in the succeeding
slides they are all going to go together. Now you can I could have also drawn plants to create a wetland here that
would be sitting on this platform instead of the cityscape but here i wanted to use a sinking city
like new orleans to illustrate the idea of subsidence okay now all you have to do is to duplicate this slide and if you select the slide over hear here in your slide navigator and go to edit and select duplicate that slide is duplicated and now what you can do is you can
change something on this slide to move the movie forward and, ahm, we take that out ’cause i’ve already duplicated it here and then here and what i’ve done in this slide is I’ve added uh… another component and here I’ve added a component that gives a microscopic view of soil particles and again this is just a box and it contains some drawings of soil particles that i created with line and connector option here i just use the scribble and drew a particle and I… filled it with a brown fill so and you can move it in there and uh… resize it uh… you can rotate these so that they don’t all look
exactly the same uh… you can reverse them; you can do various things
with it so that’s how that’s how i created this and then again I grouped all of those
so that they all move together and here they are ungrouped and grouped. okay so that’s that’s a key point to
keep in mind Then what i wanted to do… was I
wanted to show what happens when the particles are
squeezed together and what i did then was to squash the box and to do that uh… all you do it is grab one
of these points and pull the box down so that it is, ah, smaller and the
vertical direction and so that’s that’s all i did to create this next this next slide and uh… as I’m doing uh… adding these elements i’ve started adding text as you see here and arrows just a very simple explanation uh… of what is going on uh… as water and gas are squeezed out of the spaces between
soil particles the soft sediments compact and I add extra slides in here so that i have enough time if i want
to add voice over and and explain or read what is written in the text Okay now the next one…you can see
what i’ve done here it is I’ve started i removed the microscopic view of the soil particles and now i’m beginning to animate the movement of the soil surface and
again all i did was I moved the soil surface by squeezing the box from that position to this position and so when you go from this slide to
this slide it appears that the soil surface is sinking and i do it again in the next slide and squeeze the box even lower and i continue doing that and as you scroll through these you can see it looks like the soil surfaces are decreasing and again
it’s important to duplicate each previous slide so everything is precisely
the same it’s in the precisely the same position except for the element that you
want to be changing So next I moved to explaining sea level rise and what causes this and so i added another uh… bit of text
here and then in the next slide I… introduced a photograph showing
an icescape an added some text explaining that as
global temperatures rise and land based ice melts oceans expand and if we scroll through that we then see what’s happening. I am
raising the height of the ocean surface. And, it keeps getting higher and higher and then i explained that this is called
eustatic sea-level rise. and then in the final slides i wanted
to explain the concept of relative sea level rise and so for that what i did was i simply
added a dashed line showing where the ocean surface was
initially and then had an arrow…put in an arrow
pointing to where it ended up and so this this shows the distance over which the ocean height has changed and then in the following slide I put in another dashed line showing where the land form was initially and where
it ended up and uh… combined this equals the total submergence that this
cityscape is experiencing so now we’ve got a complete sequence of slides starting
from the beginning and we scroll through them and you begin to see how the movie is going to come out okay i’m going to stop there and i will
continue the tutorial in part two
