- Coke density: very useful. It is very difficult for them to understand the relation between mass and volume, even when they know examples of objects which are more dense than others. Advantage: you can reward a student with a coke if he or she answer a question correctly. I found also the video very accurate to make them realised about what they eat or drink, and how important is to have a balanced diet.Lab Mistery Solution
- You can also put together some liquids into a bottle such as alcohol, oil, water and golden syrup to see the layers depending on their density.
- Cheese candles: with this lab we could teach them to notice the difference between observations and inferences.
- Bess Beetle Warm Up Question: If the beetle could talk, I'm sure he would disagree, but it's a good lab for students. In order to find what percentage of their body mass a Bess Beetle can pull, we added some weights to a clip tied to a string tied to the mid section of the poor Beetle. What they can learn from this lab is that sometimes they are able to check the information they are told.
On Wednesday 29th we continued with the following labs:
- Egg Bungee Jump: In this lab we should predict how many rubber bands will it take to successfully complete a Bungee jump from the ceiling of the classroom. The students will need to apply their ideas about potential and kinetics energy and how they are related. Furthermore, they will need to apply the scientific methodology to collect the data.
- Lab Mistery Solution: Working in pairs, we should identify which letters of unknown substances matched with which numbers. The most interesting learning in this is to be aware of how important communication is in the field of science. We must communicate our results to our partner in the better way in order to reach solution for a problem. In addition, they will learn that in investigation the individual work is as essential as the collective work.
