What is so special about science anyway?

What do scientists do that is so special?

These articles and resources link with classes 1 and 2 of my Young Scientists course. Unlike my usual lists of resources, these are largely aimed at parents and teachers. There are many texts for reading, with a few lesson plans in there.

If anyone has any good resources that specifically deal with the scientific method and are not articles, blog posts or lesson plans, then please let me know.

1.What is science?

The Understanding Science site from the University of California at Berkeley is a great resource. Here’s their article about what science is.

I’ve used their Mystery Boxes activity a few times and still think it is a good one.

Also see their science checklist here .

2. What do scientists look like?

Let’s get rid of the awful stereotypes of mad, male, white, geeky scientists in white lab coats with glasses and crazy hair. Yes, some scientists fit the stereotype, but science is far more applicable and accessible than that. Here are some pictures of real scientists in many different fields, and information on PBS Kids about what they do in their jobs.

There’s also a blog called Real Scientists which I’d love to recommend but I don’t think it’s particularly child friendly, unless your child doesn’t mind wading through piles of text. Maybe try looking at the tags #realscientistsofInstagram or #womeninscience on Instagram.

3. Benefits of science

Science impacts all of our lives. You can’t be a ‘science skeptic’, even if you claim not to understand science, because science, and the benefits of science are all around us. (Another page from the University of Berkeley’s Understanding Science website.)

Maybe you could play an informal game with your child where you both think of any area of life and say how science helps us in that area. For example, science helps us to play sports not only by understanding how our body works and how nutrition fuels our muscles, but also by understanding the psychology of visualisation.

4. The scientific method

Science Buddies have an overview with resources and free printable poster. (The image below just shows a section of the poster.)

I also liked this explanation by Alina Bradford on livescience.com.

“Science is a systematic and logical approach to discovering how things in the universe work. It is also the body of knowledge accumulated through the discoveries about all the things in the universe.”

How to Make your Science Project Scientific.” This book was great last year for teaching my 10 year old about the scientific method, although it is very wordy with few diagrams or pictures.

5. Asking questions

Read this article from The Guardian (Jan 2014).

6. Quantitative vs qualitative observations

There’s a good lesson here on Teachers pay Teachers.

This cartoon video is a bit annoying but does emphasise the difference between quantitative and qualitative measurements

7. Forming hypotheses

The science kids at home website has a clear and simple explanation of hypotheses.

Here is an activity linked to the ‘Dinosaur Train’ TV program, for younger children, but with adaptation or extension ideas for older children.

Note that the hypothesis formed must be testable and falsifiable. In my classes I ask the children to predict not only what will happen if their hypothesis is correct, but what will happen if their hypothesis is incorrect.

 

What do you think?

Were these links helpful? I’d love to know what you use to help your primary children understand the scientific method.

 

Young Scientists 2016

I started my YOUNG SCIENTISTS course again this term. I’m trying to get primary children thinking and working scientifically!
Last year, when I presented this course for the first time, all the children had plenty of fun but I had to re-think what I was doing after the first few classes. This year’s course has loads of new activities plus some old favourites like making slime. It is still my hope that in carrying out all the activities the children will start to understand about what the scientific method means.

The photos above are from last year’s course.

This term, we started by discussing the questions “What is science?“”What do scientists look like?” and “What do scientists do?” The children sorted some cards with pictures of real scientists and other famous figures. They also drew a picture of a (stereo)typical scientist on my  whiteboard. The aim of this was to show them that scientists do not conform to the stereotypes and that anyone can be a scientist.

We used my mystery boxes (based on the instructions on the Understanding Science website) but I didn’t spend very much time on this. I’ve done this activity with some of the children already and it is a great activity but I probably should have cut it out from this class to allow more time for the measuring activity which followed.

I was trying to get the children to appreciate the value of quantitative observations. I had provided three activities that required the children to take averages. I asked them to find the mass of one M&M (without precise scales), the thickness of one piece of paper and the time for one heartbeat. I’m not sure that many of the children understood what they were meant to do. I instructed a few children on how to take their pulse, and I set a minute timer on my phone but not all children did this, and one child still insisted that his heartbeat was once every 2 seconds, without measuring it.

In the second class I talked a little about last week’s activity and then introduced the idea of testable and non-testable questions. In order to investigate a question scientifically, we must first of all pose it as a question. Simply saying “I am interested in the water absorption properties of nappies (diapers)” doesn’t provide a question that can be tested. Instead you could say “Do certain types of nappies absorb more water than others?” Then you can turn it into a testable question by choosing several named brands and setting up an experiment where a measured volume of water is poured onto them and you measure how much is not absorbed.

The activity for this week was making slime, but doing so in a quantitative way. There are instructions all over the internet for this. I used the instructions from the Science Buddies site because it is set up more like an experiment than just a sensory activity. In this experiment you compare the slime produced with different ratios of glue solution to borax solution. We discussed the safety aspects of using borax and all children decided to wear safety glasses when doing the activity. I wanted the children to fill out an investigation sheet including their hypothesis and predictions, but again this meant that the time for actually making the slime was limited. I’ll try to learn from this and allow more time for the activities in later classes.
I provided the investigation sheet because towards the end of the course the children will carry out their own investigation and present it to the rest of the class. This will probably be done in pairs or groups. I want them to get used to the planning part of scientific investigations and not just carrying out the investigation.
Here’s a brief outline of the next few weeks:
Class 3: Variables. Another hands on activity (investigating the foam produced by dishwashing liquid). Planning an experiment to do next week.
Class 4: Carrying out the experiments planned in Class 3. Recording the results and drawing conclusions.
Class 5: Analysing results and sharing results (communication and collaboration between scientists). I will show a poster of a scientific experiment so they see one way that scientists share their work with others. Start to plan the experiments they will carry out and present to the group.
Class 6: Carry out the experiments they planned in Class 5. Record results. Discuss and decide if they want to change anything.
Class 7: Final experiments – repeating or changing what they did last week. Starting to prepare their talks or posters for the last week. (The rest of the preparation will need to be done at home.)
Class 8: Final talks/posters, presenting their investigations to the rest of the group.
