At Cogitania’s Saturday Botany workshop fourth graders continued their exploration of plant identification and the classification system first introduced by Carl Linnaeus, a Swedish Botanist.
Read MoreThis week we continued exploring different cognitive biases.
Read MoreAt Cogitania’s Saturday Botany workshop fourth graders returned to Brookline to determine the identity of the plants the students observed at the Tower Hill Botanic Garden.
Read MoreThis Monday completed our work with motion in 2 dimensions given an initial starting angle. Again, we started the session reviewing Pythagorean theorem and basic trigonometry and went over the basic equations that govern projectile motion.
Read MoreAt Cogitania’s Saturday Botany workshop fourth graders visited the Tower Hill Botanic Garden in Boylston, Massachusetts. As the students arrived at the garden the rain stopped just in time to allow us to explore the outside gardens.
Read MoreThis week, we explored the notion that because the brain provides us with many shortcuts in life (which allows us to spend less effort to do everyday tasks), sometimes the shortcuts can lead us to behave in ways that are illogical.
Read MoreToday we took a more detailed look at the diffusion equation to understand it's nature and behavior, in preparation for understanding its origin. Our starting point was to review last week's idea that the concentration profile evolves according to how "concave" the concentration profile is.
Read MoreAt Cogitania’s Saturday Botany workshop fourth graders explored bulbs and bulb-like structures that are the plant food storage organs during dormancy.
Read MoreGoing places with 2D Projectile Motion
Read MoreThe students were asking many excellent questions, and the best part is that sometimes they were answering each others' questions.

Next time, we will start to see the relationship between Brownian motion and diffusion by thinking about the spreading of ink in water
Read MoreThis Monday we focused continued out investigation into Kinetic and potential energy. Students again worked with their projectile motion devices and we recorded the data and used Excel to interpret out findings. With the data, we could back calculate the max height of the Ping-Pong projectile given the elastic membrane being pulled back “x” inches.
Read MoreThis week, we picked up on where we left off and talked about the Stroop effect, which shows how interference can affect performance on a task. We made our own variations of the Stroop task (ask them to test them on you!).
