We practiced observing in class and saw some fun reactions.  After we learn more in the unit we will determine why the reactions took place.

In class we had 6 mystery substances.  We used physical properties to figure out if the substances were powders and crystals.  We also found out that vinegar is an indicator for baking soda and iodine is an indicator for starch.  We learned about using the pH scale to find out if our substances were acids or bases and we learned that substances react to heat.

In class we made math board games about factors, multiples, and divisibility rules.  My team made a game about multiples.

In class we learned about 3 dimensional solid figures.  We learned that these shapes are 3 dimensional because you can measure their length, width, and height.  We learned about the faces, edges, and vertices of our shapes and we made nets of different 3 dimensional figures. 

In Math Enrichment we created frequency tables, bar graphs, and line plots using data we collected.
