Science

We have started a new science unit - Mixtures and Solutions. In this unit students will experiment with a variety of materials to see how they combine together. Throughout the unit we are also focusing on making detailed observations, keeping organized notes, making predictions and recording our outcomes. We began by combing a variety of fruits to make our first mixture!

     We followed this up by experimenting to see if combining gravel, salt and diatomaceous earth with water would also create a mixture. We then discussed whether or not mixtures can be separated, and if so how. We used filters and evaporation as methods of separating mixtures. We have discussed and defined both mixtures and solutions. Every solution is a mixture, but not all mixtures are solutions. Ask your child an example of a mixture and a solution. 

We explored the process of saturation, using both salt water solution and citric acid. We weighed our 50 mL of water before we added the materials, and then after to see how much salt or CA it would take to saturate the water. 

We will also explore chemical reactions.
