This lab provides two chemical reactions for students to perform in groups (endothermic and exothermic) and one teacher demonstration reaction (elephant toothpaste). After each reaction the students can reflect on which type of reactions they performed/observed and they are introduced the counting atoms and balancing equations for chemical reactions.

This lab requires two separate days for data collection to show the effects of osmosis using dissolved shell eggs and two solutions (Solution A - Hypotonic and Solution B - Hypertonic). The students will find starting and ending mass to calculate percent change in mass and graph their findings. Students will then reflect on which type of solutions each would be classified and what would be considered an Isotonic solution if one were given.

Biology Homeostasis Lab Activity Students will perform a series of activities to increase and decrease their heart rate and record bpm. Students will graph and answer reflection post-lab questions to make connections to homeostasis and bodily functions/processes.

Properties of Water Lab Activity Water Penny Drop Lab Activity Students will answer questions about experimental design and properties of water to test the validity of an experiment while re-enforcing the concept of cohesion and adhesion (capillary action).

Symbiotic Relationship Comic Strip Project - Assignment Students select one of the three symbiotic relationships to create a comic strip demonstrating the concepts behind their interactions. An example has been provided for reference.
