We are honored to name Joon Yeider, a 1st Grade Teacher at Chabot Elementary in Oakland, as a 2020 Science Super Star!
Joon first had her class explore how to use the Sun, a toilet plunger, and shadows to tell time – by making Sundials. This experiment can easily be duplicated by students, as all they would need is a stick and a place near soil. Importantly, it allows students to work outside during a beautiful day.
Students worked together to figure out how many rocks would be needed as markers, to tell how much time has passed.They noticed when 20 minute intervals passed and, due to their diligent observations, began to notice which direction shadows pointed depending on where the sun is in the sky. By working together, students were able to help others discover answers to incomplete perceptions.
I have an EL student who benefits from the hands-on component to Science content, but also had the group work mentality. He has started to share his ideas in his group and in whole group discussions.
After the experiment, the students were ready to write about their predictions and observations in their notebooks, but first, Joon had them review new vocabularly. By going over the experiment, clearing up misunderstandings, and making stronger connections via discussion, she ensured no student was being left behind.
Joon's top tip for other teachers:
Don't be afraid. Start off slow, maybe set a goal; more time answering the focus questions, time set aside to asses notebooks with grade level, sign up for a workshop or PD.
