Divide into science committees.
Your teacher will divide you into groups.
Formen un comités científico.
Su profesor(a) los va a dividir en grupos.
Grab all necessary materials.
Your teacher will have all materials. You need 1 tray, 4 sets of velcro dots, one pack of sand, one empty sand timer, and your science paper tools!
Tomen sus materiales.
Su profesor(a) tiene los materiales. Necesitan 1 bandeja de papel, 4 pares de velcro adhesivos, 1 paquete de arena, 1 reloj de arena vacío y los materiales de paper científicos.
Step 1:
Fold the four sides of paper tray along the dotted line.
Paso 1:
Dobla los cuatro lados de la bandeja en donde vez la línea punteada.
Step 2:
Paste the velcro dots on top of the white circles found in the corners of your paper tray. Make sure you are using a fuzzy and a scratchy velcro dot in every corner.
Paso 2:
Pega el velcro adhesivo encima de los círculos blancos encontrados en las esquinas de la bandeja. Asegurate que estes pegando el lado suave y el lado rasposo en cada esquina.
Step 3:
Connect the velcro dots together at each corner to make your tray.
Paso 3:
Pega juntos los puntos adhesivos de velcro de cada esquina para crear la bandeja de papel.

BAR GRAPHS!
Let’s take our findings from our
table and make them into a BAR GRAPH.
BAR GRAPHS!
Use the data from the table on page 75 to
create a bar graph. The # of seconds should be represented on the Y axis and the amount of sand represented on the X axis (see image).

Test your sand timer
with different materials!
Let’s test our sand timer
using other materials.
Tests with
different materials!
Remove sand from the sand timer and substitute it with sugar, salt, or water. Use the same method you used with the sand to keep track of the time.
Once you’ve tested all of them, rate them
from best to worst.
Healthy Habits!
Think of other timed healthy habits.
Healthy Habits!
In your groups, research other healthy
habits (brushing teeth, mindfulness breathing, exercising) and find out how much time
is the ideal amount of time to do it for.
Game Design
Create your own game that uses
the sand timer you just created.
Game Design!
Your game should be focused on healthy habits. For example; promoting exercise by encouraging people to do certain movements for 30 seconds (running in place, jumping jacks, hopping on one foot, push ups, sit ups, etc.).
Reflect!
Think about your own habits.
Reflect!
Use this time to reflect and write about your own habits on a notebook. You can write:
